Please refer to FIGS. 1-4 together. An electronic device 100 according to an embodiment of the present invention includes a casing 20 , a display screen 30 and a cover 40 . The electronic device 100 may be a mobile phone or a tablet computer or the like. The electronic device 100 in the embodiment of the present invention is described by taking a mobile phone as an example. Of course, the specific form of the electronic device 100 may also be other, which is not limited here. Since the display screen 30 in the mobile phone is covered by the cover plate 40 , the indication of the display screen 30 in the illustration is the approximate position of the display screen 30 .

The casing 20 includes a bottom wall 22 and a side wall 24 extending from an edge of the bottom wall 22 . A groove 26 is enclosed by the bottom wall 22 and the side wall 24 . The display screen 30 is accommodated in the groove 26 . The cover plate 40 covers the display screen 30 and is supported on the side wall 24 . A light absorbing structure 10 is disposed between the edge of the cover plate 40 and the housing 20 to absorb the light emitted by the display screen 30 and transmitted to the edge of the cover plate 40 .

Please refer to Figure 4. While the display screen is emitting light, the light emitted by the display screen will be emitted from the edge of the cover plate and reflected by the housing, and then emitted to the outside of the housing, thus forming a strong light between the cover plate and the housing , affecting user experience.

Please refer to FIG. 5 , the electronic device 100 according to the embodiment of the present invention absorbs the visible light generated by the display screen 30 and reflected by the cover plate 40 to the outside of the housing 20 by setting the light absorbing structure 10 , so that the visible light cannot be reflected out of the cover plate 40 . The edge is used to solve the problems that affect the user's use and experience. The process is simple, the implementation difficulty is relatively low, and it has economic benefits.

Please further refer to FIG. 1 and FIG. 3 , in the electronic device 100 , the casing 20 is mainly used for accommodating and protecting these components, preventing external factors from damaging these components. In addition, the housing 20 is substantially a rectangular frame, so that the electronic device 100 formed after the housing 20 is assembled with the electronic device 100 is rectangular. In order to make the electronic device 100 more beautiful, the corners of the casing 20 may be rounded so that the electronic device 100 has a rectangular shape with rounded corners. In addition, the housing 20 can be formed by machining aluminum alloy with a CNC machine tool, or can be formed by injection molding of polycarbonate (PC) or PC+ABS material. The bottom wall 22 and the side wall 24 form a groove 26 to accommodate the display screen 30, which improves the tightness and integrity of the mobile phone components.

The material of the cover plate 40 may be made of light-transmitting materials such as glass, ceramics or sapphire. Since the cover 40 is an input part of the electronic device 100 , the cover 40 is often touched by bumps or scratches. For example, when a user puts the electronic device 100 into a pocket, the cover 40 may be scratched and damaged by a key in the pocket of the user. Therefore, the material of the cover plate 40 can be made of a material with higher hardness, or a hardened layer can be formed on the surface of the cover plate 40 to improve the scratch resistance of the cover plate 40 .

It can be understood that the cover plate 40 is supported on the side wall 24, that is, there is physical contact between the cover plate 40 and the side wall 24, and in order to improve stability, the cover plate 40 and the housing 20, that is, the side wall 24, can be bonded by optical glue. For fixing, the optical glue not only adheres and fixes the cover plate 40 and the housing 20 , but also transmits the light emitted by the display screen 30 .

Referring to FIGS. 5 and 6 , in some embodiments, the light absorbing structure 10 includes a light absorbing layer 12 coated between the edge of the cover plate 40 and the housing 20 .

It can be understood that the light-absorbing layer 12 is coated between the edge of the cover plate 40 and the housing 20 to absorb the light generated by the display screen 30 and reflected in the cover plate 40 . Since the visible light is reflected through the edge of the cover plate 40 , Therefore, coating the light absorbing layer 12 on the edge of the cover plate 40 can absorb visible light more effectively.

In one embodiment, the light absorbing layer 12 can be ink. If the panel of the display screen 30 is black, black ink is applied; if the panel of the display screen 30 is white, the edge of the cover plate 40 is coated with white ink and then black ink. This can ensure the consistency of the appearance of the mobile phone and solve the problem that strong visible light affects the user's use and experience. The number of layers of ink applied to different appearances of the electronic device 100 is different. The more layers of ink, the darker the displayed color, and the electronic device 100 with a darker appearance is suitable, which can be selected in actual implementation. The ink has a large density, so visible light cannot penetrate the ink layer and be absorbed, and the ink can be dried and bonded quickly after coating. The dried ink film layer has water resistance, acid resistance, alkali resistance, light resistance, abrasion resistance, Wear-resistant and other resistance, ink is easy to obtain, and the implementation method is simple and easy to implement, which can reduce production costs. Of course, the light-absorbing layer 12 is not limited to ink, and can be other materials with the same or similar functions, which can be selected in specific implementations.

Please refer to FIG. 5 , in some embodiments, the light absorbing layer 12 is coated on the side 41 of the cover plate 40 .

The visible light is reflected to the side of the electronic device 100 through the edge portion 48 of the cover plate 40. Specifically, the visible light is reflected through the side surface 41 of the cover plate 40. The side surface 41 is the part of the cover plate 40 close to the side wall 24 of the middle frame. For a curved surface with a certain radian, coating the light-absorbing layer 12 on the side 41 can effectively absorb reflected visible light, and the range of visible light reflected by the side 41 can reduce the coating area of the light-absorbing layer 12 to avoid waste of resources. Of course, the light-absorbing layer 12 is not limited to be coated on the side 41 of the cover plate 40, and can be coated on other positions under the premise of ensuring that visible light is absorbed or that visible light cannot be reflected to the side of the mobile phone, which is selected in actual implementation.

In some embodiments, the side wall 24 includes a mounting surface 242 connected to the side surface 41 of the cover plate 40 , and the light absorbing structure 10 includes the rough surface 14 formed on the mounting surface 242 .

It can be understood that the surface of the installation surface 242 is a rough surface 14, which can disperse and reflect visible light, and reduce the reflection intensity and concentration of visible light. Likewise, in one embodiment, the light-absorbing layer 12 can be coated on the mounting surface 242 to form two or more layers of light-absorbing layers 12 in the electronic device 100 to enhance the absorption of visible light.

Referring to FIGS. 5-9 , in some embodiments, the cover plate 40 includes a flat plate portion 42 and a curved portion 44 extending downward from the edge of the flat plate portion 42 , and the cover plate 40 is supported on the side wall 24 by the curved portion 44 superior.

The arrangement of the flat part 42 and the curved part 44 of the cover plate 40 conforms to the user's usage habits. The flat part 42 is easy to operate and makes the appearance smooth and beautiful. The curved part 44 is convenient for the user to hold and carry. stability of electronic equipment.

In some embodiments, the display screen 30 includes a display area 32 and a non-display area 34, the cover plate 40 covers the display screen 30 and includes a middle portion 46 corresponding to the display area 32 and an edge portion protruding from the edge of the middle portion 46 48 , the edge portion 48 covers the non-display area 3432 , and the light sensor 50 is disposed under the edge portion 48 .

Since the cover plate 40 covers the display screen 30, the cover plate 40 and the display screen 30 have structural similarities. It can be understood that the display area 32 of the display screen 30 is a flat panel, the non-display area 34 is a curved surface, and the display screen 30 is a curved screen. , so that the light passes through the curved surface so that the light sensor 50 arranged under the edge area of the display screen 30 receives the light, and then transmits the data signal to the processor to realize the light receiving and analysis. Specifically, in order to ensure that the light sensor 50 can sense light entering from the edge portion 48 of the cover plate 40 , the orthographic projection of the edge portion 48 needs to cover light sensing. In one embodiment, the light sensor 50 can be disposed on the bottom wall 22 (as shown in FIGS. 6 and 7 ). In another embodiment, the light sensor 50 can be disposed on the lower surface of the edge portion 48 of the cover plate 40 (as shown in 8 and Fig. 9), more, the light sensor 50 can be 1 or more numbers such as 2, 3 or even 4 etc., and the single light sensor 50 is the most basic sense of light, and occupies the electronic device The space of the electronic device 100 is small, and the more the light sensors 50 are, the more accurate the light sensing is, and the space occupied by the electronic device 100 is also increased.

In some embodiments, the area ratio of the display area 32 to the cover plate 40 is greater than 90%.

Specifically, by setting the area ratio between the display area 32 and the cover plate 40, after the display screen 30 is pasted by the cover plate 40, the display area 32 can display the content effect with a larger size area, which not only improves a good user experience , and effectively increases the screen-to-body ratio of the electronic device 100 to achieve a full-screen effect.

In some embodiments, the light sensor 50 is a proximity sensor, and the proximity sensor is used to emit infrared light to an object outside the electronic device 100 and generate a distance detection signal according to the infrared light reflected by the object, and the distance detection signal is used to detect the distance between the object and the cover plate. The distance between 40.

The proximity sensor in the embodiment of the present invention can be understood as an infrared distance sensor, and the working principle of the infrared distance sensor is mainly based on the ranging function of infrared rays. The infrared distance sensor includes an infrared emitting tube and an infrared receiving tube. When the infrared rays emitted by the transmitting tube are received by the receiving tube for a short time, it indicates that the distance is relatively short; when the receiving tube receives the infrared rays emitted by the transmitting tube for a long time, it indicates that the distance is short Far. Automatically adjust the display and extinguishing of the display screen 30 by the distance of the detection distance. If the mobile phone is relatively close when the user answers the phone, the display screen 30 does not need to be brightly displayed, and the extinguishing of the display screen 30 can be controlled by the induction of the light sensor 50. Not only can it improve the comfort of use in different environments, prevent users from misoperation, but also save power.

Referring to FIG. 5 , in some embodiments, the electronic device 100 includes a coating layer 60 coated on the lower surface of the edge portion 48 , the coating layer 60 is used to transmit infrared light and block visible light.

In this way, the influence of visible light on the distance detection accuracy of the light sensor 50 can be eliminated, the intensity of the infrared rays emitted and received by the light sensor 50 can be ensured, and the distance detection accuracy can be improved.

In one embodiment, coating layer 60 is IR ink.

Further, the light transmittance of the IR ink to infrared rays is greater than 85%, the light transmittance to visible light is less than 6%, and the wavelength of infrared rays that can be transmitted is 850nm-940nm. Since the IR ink has low transmittance to visible light, when the electronic device 100 is viewed from the outside, the optical sensor 50 disposed under the edge portion 48 cannot be perceived based on human vision. At the same time, since the IR ink has the characteristics of high transmittance to infrared light, the light sensor 50 can stably emit and receive infrared light, ensuring the normal operation of the light sensor 50 . Of course, the coating layer 60 is not limited to ink, and can be specifically selected in an actual implementation mode under the premise of ensuring that the interference of visible light and the stability of infrared rays can be eliminated.

In some embodiments, the light sensor 50 is an ambient light sensor 50 for receiving the visible light transmitted through the edge portion 48 and generating a light intensity detection signal for detecting the intensity of the visible light.

Specifically, when the user uses in different environments, the ambient light is received by the light sensor 50 through the curved surface 44 of the cover plate 40, and the intensity of the external light is calculated through the data of the processor so as to automatically adjust the brightness of the display screen 30, which improves the The experience of the electronic device 100 and the comfort of use, and the power saving, prolong the use time of the electronic device 100 .

In some embodiments, the lateral dimension of the cover plate 40 is larger than that of the display screen 30 .

In this way, the cover plate 40 can cover the display screen 30 relatively comprehensively, and cooperate with the housing 20 to better protect the display screen 30 .

In some embodiments, display screen 30 includes an OLED display screen.

Specifically, the display screen 30 may be an OLED display screen (Organic Light-Emitting Display, organic light-emitting display screen), the OLED display screen has excellent light transmission performance, and the light sensor 50 may be arranged under the OLED display screen without affecting the display screen 30. For the normal display function, the light can also pass through the OLED display screen and be received by the light sensor 50 . It can be understood that the display screen 30 may also adopt a Micro LED display screen, and the Micro LED display screen also has good light transmittance. Of course, these display screens 30 are only exemplary, and the embodiments of the present invention are not limited thereto.
