Description

Anti-peep film, display device and terminal and preparation method thereof Technical field

The present invention relates to the field of optical protective film technologies, and in particular, to a peep prevention film, a display device and a terminal, and a method for fabricating the same.

Background technique

Today's mobile phones, tablets and other terminal devices use a wide viewing angle, which provides a good display experience when reading or browsing content at a large viewing angle. However, while the user enjoys the screen display effect, the people in the vicinity of the environment can also clearly see the display content of the screen, and there is a great hidden danger to the security and privacy of personal privacy.

Nowadays, the solution for reducing the viewing angle of the display device for mobile phones, tablets and other terminal devices is to attach a peeping film to it, for example, attaching a peeping film to a notebook. ATM machines mostly pay a peep-proof film on the surface of the screen, reducing the viewing angle of the display, so that only the operator's perspective can clearly see the display content, and achieve the purpose of protecting privacy. The principle of the privacy film is a polarizing effect, which can reduce the viewing angle, but the viewing angle has only one range. And if it is attached to the surface of the display screen, only one of these ranges will be used unless the anti-spy film is torn off, which causes cost waste and difficulty in operation.

Summary of the invention

The embodiment of the invention provides a peeping film, a display device, a terminal, a peeping film manufacturing method and a terminal display method, which are used for freely setting different display screens according to different usage scenarios that the user can use. Perspective.

In view of this, the first aspect of the present application provides a privacy film, the privacy film comprising:

a driving layer and a retaining wall structure; the driving layer is provided with a plurality of the retaining wall structures; the retaining wall structure is a transparent cavity filled with a transparent filling liquid and non-transparent particles, the non-transparent particles carrying the same sex Charge.

When the anti-spy film is applied, a retaining wall structure is next to a pixel, and the retaining wall structure is transparent in some cases, and can be blocked by changing the distribution of non-transparent particles in the body when needed. The line of sight of the pixel is viewed from some angles to achieve the anti-peep effect of the anti-peep film. It should be noted that the retaining wall structure can determine the angle of view of the anti-peep film by different distribution patterns of non-transparent particles in the body. The non-transparent particles can move freely in the transparent filling liquid, so that when the non-transparent particles receive an external force due to the voltage, the distribution pattern can be determined as needed.

In conjunction with the first aspect of the present application, a first embodiment of the first aspect of the present application includes:

The transparent carrier and the circuit layer are disposed in the transparent carrier. When the circuit layer is loaded with voltage, the distribution of the non-transparent particles in the retaining wall structure is changed.

The role of the transparent carrier is mainly for carrying the circuit layer. When the circuit layer is energized, according to electromagnetic induction, the distribution of charged non-transparent particles in the retaining wall structure can be affected, thereby changing the viewing angle of the anti-spy film. In some feasible embodiments, the lines distributed in the circuit layer may be in one-to-one correspondence with the retaining wall structure, or may overlap with a part of the retaining wall structure, which is not limited herein.

Since the terminal using the anti-spy film can control the transparency of the retaining wall structure in the anti-peep film by controlling the voltage of the access line of the driving layer, the user can freely set the viewing angles of different display screens according to different use scenarios. There is no need to tear off the peeping film and put it on. Moreover, since the anti-spy film is attached to the display screen, each of the retaining wall structures overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.

A peep-proof film sticker is attached to the display screen, and the structure of the anti-peep film retaining wall overlaps with the pixel black area of the display screen.

A transparent adhesive layer is disposed between the privacy film and the display screen for bonding the privacy film and the display screen. The privacy film and display can be bonded by an optically clear adhesive, also known as a clear adhesive layer. The optically clear adhesive referred to herein may be an optical clear adhesive (English: optical clear adhesive, abbreviation: OCA) or an optically clear resin (English: Optical Clear Resin, abbreviation: OCR), which is not limited herein.

Since the terminal using the anti-spy film can control the transparency of the retaining wall structure in the anti-peep film by controlling the voltage of the access line of the driving layer, the user can freely set the viewing angles of different display screens according to different use scenarios. There is no need to tear off the peeping film and put it on. Moreover, since the anti-spy film is attached to the display screen, each of the retaining wall structures overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.

The user can freely set the viewing angles of different display screens according to different usage scenarios, without the trouble of tearing off the peeping film. When the anti-spy film is attached to the display screen, since each of the retaining wall structures overlaps with one pixel black area of the display screen, overlapping with the pixel light-emitting area is avoided to affect resolution and brightness.

A third aspect of the present application provides a terminal, including:

a processor, a bus, and a display device provided by the second aspect of the present application; the processor and the display device are connected by a bus; the processor is configured to acquire a view adjustment instruction; the processor is further configured to adjust the circuit layer according to the view adjustment command a voltage to control a distribution pattern of the plurality of non-transparent particles in the transparent filling liquid, and a distribution manner of the non-transparent particles in the transparent filling liquid determines a size of a display viewing angle of the terminal.

Since the terminal using the anti-spy film can control the transparency of the retaining wall structure in the anti-peep film by controlling the voltage of the access line of the driving layer, the user can freely set the viewing angles of different display screens according to different use scenarios. There is no need to tear off the peeping film and put it on. Moreover, since the anti-spy film is attached to the display screen, each of the retaining wall structures overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.

A fourth aspect of the present application provides a terminal display method, including:

Obtaining a viewing angle adjustment instruction; adjusting a voltage of the circuit layer according to the viewing angle adjustment command to control a distribution manner of the plurality of non-transparent particles in the transparent filling liquid, and determining a distribution manner of the non-transparent particles in the transparent filling liquid The size of the display view of the terminal.

In some feasible embodiments, if the command accepted by the terminal is to reduce the display viewing angle, the road layer is loaded with the same electrical voltage as the charge carried by the non-transparent particles to drive the non-transparent particles away from the transparent filling liquid. The direction of the driving layer is moved such that the retaining wall structure forms a non-transparent retaining wall of a certain height, the height of which determines the size of the display viewing angle of the terminal.

It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

Since the terminal using the anti-spy film can control the transparency of the retaining wall structure in the anti-peep film by controlling the voltage of the access line of the driving layer, the user can freely set the viewing angles of different display screens according to different use scenarios. There is no need to tear off the peeping film and put it on. Moreover, since the anti-spy film is attached to the display screen, each of the retaining wall structures overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.

It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

As shown in FIG. 1 , the embodiment of the present application provides a privacy film 100, and the privacy film 100 includes:

The driving layer 101 and the retaining wall structure 102 are provided with a plurality of retaining wall structures 102 on the driving layer 101.

In the embodiment of the present invention, when the privacy film 100 is applied, that is, when the privacy film is attached to the display screen, a voltage is applied to the driving layer 101, and the privacy film 100 can change the viewing angle of the display screen. . It should be noted that the magnitude and electrical properties of the loaded voltage have an influence on the size of the viewing angle of the display screen 100.

The retaining wall structure 102 is a transparent cavity filled with a transparent filling liquid 1021 and non-transparent particles 1022, and the non-transparent particles 1022 carry a homogenous charge.

In the embodiment of the present invention, the transparent filling liquid 1021 may be a transparent, non-corrosive solution. This is not a limitation. In the embodiment of the present invention, the non-transparent particles may be pure black particles or white particles, or may be mixed colors, as long as they are non-transparent and electrically chargeable particles, other materials may also be used herein. . In addition, the shape of the non-transparent particles 1022 may be spherical or cubic, as long as it is small enough, and can flow in the transparent filling liquid 1021, which is not limited herein. The material of the non-transparent particles 1022 may be a charged metal or other materials capable of carrying a charge, which is not limited herein. It should be noted that it is common knowledge to charge the non-transparent particles 1022, and no further details are provided herein.

In the embodiment of the present invention, the retaining wall structure 102 determines that the privacy film 100 changes the size of the viewing angle of the display screen. In some possible embodiments, when the privacy film 100 is attached to the display screen, a retaining wall structure 102 is adjacent to a pixel of the display screen. Typically, the retaining wall structure 102 is vertically disposed on the driving layer 101. Above, of course, the retaining wall structure 102 can also be disposed obliquely on the driving layer 101. The retaining wall structure 102 is filled with a transparent filling liquid 1021 and non-transparent particles 1022, and the non-transparent particles 1022 can be changed in distribution by the driving layer 101.

Specifically, when the driving layer 101 is not applied with a voltage, the non-transparent particles 1022 are maintained at the bottom of the retaining wall structure 102 adjacent to the driving layer 101. When the driving layer 101 is loaded with a voltage, the distribution of the non-transparent particles 1022 is changed. For example, the non-transparent particles 1022 are driven to the middle, top, or evenly distributed of the retaining wall structure 102 to obstruct the view line at certain angles of the display screen, thereby achieving an anti-spying effect.

In the embodiment of the present invention, a plurality of retaining wall structures 102 are disposed on one side of the driving layer 101, and the distribution of the non-transparent particles 1022 in the body of the retaining wall structure 102 can be driven by the driving layer 101. Specifically, when the driving layer 101 is loaded with a voltage, the distribution manner of the non-transparent particles 1022 in the body of the retaining wall structure 102 is directly affected, thereby determining the size of the viewing angle of the privacy film 100. Since the distribution of the driving layer 101 by the magnitude of the applied voltage can flexibly control the distribution of the non-transparent particles 1022 in the body of the retaining wall structure 102, the viewing angle of the privacy film 100 can also be flexibly controlled. It should be noted that the retaining wall structure 102 generally needs a plurality of, preferably, when applied, just distributed in the non-pixel area of the display screen, that is, in the black area of the pixel, in the wide-angle mode, It won't block any pixels. When it's a narrow angle, it can also control the angle very well. In other feasible embodiments, the retaining wall structure 102 may be disposed only in the vertical pixel black strips as needed, or the retaining wall structure 102 may be disposed only in the horizontal pixel black strips, or may be based on other The requirements set the distribution of the settings, which is not limited here.

The driving layer 101 includes a transparent carrier 1011 and a circuit layer 1012. The circuit layer 1012 is disposed in the transparent carrier 1011. When the circuit layer 1012 is loaded with a voltage, the non-transparent particles 1022 are distributed in the retaining wall structure 102. The situation has been changed.

In the embodiment of the present invention, the driving layer 101 is composed of a transparent carrier 1011 and a wiring layer 1012. The material of the transparent carrier 1011 may be polyethylene terephthalate (PET) or glass, and is not limited as long as it is non-conductive and transparent. The circuit layer 1012 is a conductor, and may be made of metal or other non-metallic conductor materials, which is not limited herein.

The circuit layer 1012 is disposed in the transparent carrier 1011. The circuit layer 1012 is disposed in the transparent carrier. When the circuit layer 1012 is loaded with a voltage, the distribution of the non-transparent particles 1022 in the retaining wall structure 102 is changed.

In the embodiment of the present invention, the transparent carrier 1011 functions mainly for carrying the circuit layer 1012. When the circuit layer 1012 is energized, the distribution of the charged non-transparent particles 1022 within the retaining wall structure 102 can be affected according to electromagnetic induction, thereby changing the viewing angle of the privacy film 100. In some feasible embodiments, the lines distributed in the circuit layer 1012 may be in one-to-one correspondence with the retaining wall structure 102 or may overlap with a portion of the retaining wall structure 102, which is not limited herein. It is generally not set in the pixel area, because if the line distribution in the circuit layer 1012 cannot affect the retaining wall structure 102, there is no sense of existence, and the retaining wall structure 102 is generally not disposed in the pixel area because it is disposed in the pixel area. In the present invention, there is no meaning in existence.

The retaining wall structure 102 is a transparent cavity. The transparent cavity is filled with a transparent filling liquid 1021 and a plurality of non-transparent particles 1022 are built therein. All the non-transparent particles 1022 carry a homogenous charge.

In the embodiment of the present invention, the non-transparent particles 1022 can be freely moved in the transparent filling liquid 1021, so that when the non-transparent particles 1022 receive an external force due to electricity, the distribution pattern can be determined as needed.

It should be noted that the function of the non-transparent particles 1022 is to block the line of sight in other directions for the adjacent pixels, so that the anti-spy film 100 can play its intended role. Therefore, the higher the non-transparency of the non-transparent particles 1022, the better the anti-seepage effect is when the other conditions are constant.

In some possible embodiments, as shown in FIG. 5, a schematic diagram of a process for fabricating the anti-seepage film 100 for the anti-seepage film 100 is used: a transparent transparent film is formed by using an optical transparent adhesive; and a plurality of transparent base films are formed on one side of the transparent base film. a groove; fill all the grooves with a transparent filling liquid 1021; place a plurality of non-transparent particles 1022 in the transparent filling liquid 1021, the non-transparent particles 1022 carry a homogenous charge; a layer made of a transparent solid material a transparent carrier; a circuit layer is disposed in the transparent carrier; and the transparent carrier is attached to the recessed side of the transparent base film.

In some possible embodiments, the transparent base film is made of optical transparent adhesive OCA as a material, and one side of the transparent base film is a groove in the shape of the retaining wall structure 102, and may also be a transparent resin OCR. The recess is filled with a transparent filling liquid 1021 so that the built-in material can move freely, so that the privacy film 100 can function. In some feasible embodiments, the groove may be a rectangular parallelepiped or a cylinder. The top view may be a groove or other shape as long as it is in the black area of the pixel when used. There is no limit. It should be noted that, when other conditions are constant, the more black areas of the pixels provided with the retaining wall structure 102, the better the anti-spying effect. In the embodiment of the present invention, the transparent base film functions as a bonding on the one hand, and functions as a cavity for accommodating the transparent filling liquid 1021 and the non-transparent particles 1022 on the one hand, as long as the above functions can be performed, other materials are also used. Yes, it is not limited here.

In the transparent filling liquid 1021, a plurality of the non-transparent particles 1022 are placed, and the non-transparent particles 1022 carry a charge of the same nature, that is, a positive charge or a negative charge, which is not limited herein. The recess is filled with a filling liquid 1021, and the filling liquid 1021 has built-in charged non-transparent particles 1022. This is the retaining wall structure 102 referred to in the embodiment of the present invention. In some possible embodiments, the transparent solid material may be made of phthalate PET or glass, as long as it is transparent and can be insulated, which is not limited herein.

In the embodiment of the present invention, the circuit layer 1012 is a conductor, and may be made of a metal or a non-metal conductor material, which is not limited herein. When a voltage is introduced to the wiring layer 1012, the non-transparent particles 1022 undergo a corresponding reaction according to the voltage. That is, when the electrical conductivity of the introduced voltage is the same as the electrical conductivity of the charge carried by the non-transparent particles 1022, the non-transparent particles 1022 are driven away from the driving layer 101, and conversely, are attracted to the driving layer 101.

It should be noted that the circuit layer 1012 in the driving layer 101 can be loaded with alternating current to control the position of the non-transparent particles 1022 in the retaining wall structure 102 at the retaining wall structure 102. In other possible embodiments, the circuit layer may also be divided into two layers, one layer is loaded with the same electrical charge as the non-transparent particles 1022, and one layer is charged with the opposite polarity of the non-transparent particles 1022 to control The position of the non-transparent particles 1022 in the retaining wall structure 102 is at the position of the retaining wall structure 102, which is not limited herein.

In some possible embodiments, when the electrical layer is loaded with the electrical charge of the charge carried by the non-transparent particles 1022, the non-transparent particles 1022 are away from the driving layer, and it is known that the non-transparent particles 1022 are driven to the corresponding positions. Loading an electrical opposite charge to the charge carried by the non-transparent particles 1022, The non-transparent particles 1022 are placed in the desired position.

The transparent base film has no groove on one side, a groove on the other side, and a filling liquid 1021 in the groove. At this time, the surface needs to be sealed, otherwise the liquid inside may leak out. In the embodiment of the present invention, The drive layer 101 can be attached to the grooved side so that the groove can be sealed.

The user can freely set the viewing angles of different display screens according to different usage scenarios, without the trouble of tearing off the privacy film 100. Moreover, since the anti-spy film 10 is attached to the display screen, each of the retaining wall structures 102 overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.

In the embodiment of the present invention, the display 201 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like, which is not limited herein. In the display screen 201, where each pixel is distributed, and there is no pixel between each pixel, it is called a pixel black area. In the embodiment of the present invention, the retaining wall structure 102 of the privacy film 100 may overlap with the black area of the pixel. Preferably, as shown in FIG. 3, the retaining wall structure 102 of the anti-spy film 100 may overlap with the black area of the pixel one by one. That is, any pixel black area has a wall structure 102 overlapping with it, and vice versa.

In some possible embodiments, the privacy film 100 and the display screen 201 can be bonded by an optically clear adhesive, also known as a clear adhesive layer. The optically clear adhesive referred to herein may be an optical clear adhesive (English: optical clear adhesive, abbreviation: OCA) or an optically clear resin (English: Optical Clear Resin, abbreviation: OCR), which is not limited herein.

The user can freely set the viewing angles of different display screens according to different usage scenarios, without the trouble of tearing off the peeping film. Moreover, since the anti-spy film is attached to the display screen, each of the retaining wall structures overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.

The terminal 300 in the embodiment of the present application is described above. The method for manufacturing the privacy film 100 in the embodiment of the present application is described below.

As shown in FIG. 7, the terminal display method includes:

601. Obtain an angle adjustment instruction.

In the embodiment of the present invention, the execution subject is the terminal 300 in the embodiment, and the processor in the terminal can acquire and execute the view adjustment instruction. In some feasible embodiments, the instruction may be from a user operating on the screen, or may be based on an externally received instruction, which is not limited herein.

602. Adjust a voltage of the circuit layer according to a viewing angle adjustment command to control a distribution manner of the plurality of non-transparent particles in the transparent filling liquid, and a distribution manner of the non-transparent particles in the transparent filling liquid determines a display viewing angle of the terminal.

In some possible embodiments, if the command accepted by the terminal is to reduce the display viewing angle, the circuit layer is energized, so that the circuit layer is loaded with the same electrical voltage as the charge carried by the non-transparent particles to drive the non-transparent The particles move in a transparent filling liquid away from the driving layer, so that the retaining wall structure forms a non-transparent retaining wall of a certain height, the height of which determines the display viewing angle of the terminal.

It should be noted that when the circuit layer is loaded with the same electrical charge as the non-transparent particles, the non-transparent particles may be brought close to the driving layer such that the height of the retaining wall structure is zero. Even when the terminal is flipped, the control of the retaining wall structure can be guaranteed.

If the command accepted by the terminal is to enlarge the display angle of view, the road layer is loaded with a voltage opposite to the electrical charge of the charge carried by the non-transparent particles or a voltage is not applied to drive the non-transparent particles in the transparent filling liquid away from the driving layer. The moving, or non-transparent, particles automatically fall on the face of the drive layer such that the height of the non-transparent retaining wall of the retaining wall structure is lowered or height-free to determine the size of the viewing angle.

As shown in FIG. 8, in other feasible embodiments, when the terminal is energized at the driving layer, if the electrical property of the energized voltage is consistent with the electrical property of the non-transparent particles, the non-transparent principle is due to the principle of homosexual repelling. The particles are away from the driving layer, and the non-transparent particles can be concentratedly distributed in a small section in the structure of the retaining wall to achieve the function of blocking the pixels, shielding the large-angle light, and reducing the viewing angle. In this case, the non-transparent particles can achieve some degree of anti-spying effect under the driving of the driving layer.

Specifically, when the voltage is the same as the electrical property of the non-transparent particle and the voltage is large, the considerable viewing angle of the pixel can reach a minimum θ3; when the voltage is the same as the electrical property of the non-transparent particle and the voltage is small, the pixel is considerable. The viewing angle may be a minimum θ1. In some feasible embodiments, θ1 may be 180°, that is, there is no anti-peep effect, which is not limited herein; when the electrical voltage of the applied voltage is the same as that of the non-transparent particles, On the contrary, since the magnitude of the voltage of different electrical properties is controllable, the considerable viewing angle of the pixel can be controlled to θ2, where θ1 ≥ θ2 ≥ θ3.

However, as shown in Fig. 8, the θ2' angle and the θ3' angle actually have no anti-peep effect. In order to achieve a better anti-spying effect, the non-transparent particles may carry different amounts of electricity, such that when a voltage is applied by the driving layer, the non-transparent particles may be relatively evenly distributed within the retaining wall structure, as shown in FIG. When the terminal is energized in the driving layer, the non-transparent particles can be relatively evenly distributed in the retaining wall structure, and a non-transparent retaining wall is formed in the retaining wall structure to shield the large-angle light, thereby reducing the viewing angle. When the electricity that is not energized or energized is opposite to the electrical property of the non-transparent particles, the transparent retaining wall body does not change the traditional direction of light, that is, restores a larger viewing angle, and the height of the charged charged ball, The purpose of controlling the viewing angle can be achieved.

The user can freely set the viewing angles of different display screens according to different usage scenarios, without the trouble of tearing off the peeping film. Moreover, since the anti-spy film is attached to the display screen, each of the retaining wall structures overlaps with a pixel black area of the display screen to avoid overlapping with the pixel light-emitting area and affect resolution and brightness.
