Description

Mobile terminal

The present invention relates to a mobile terminal having a window including curved surfaces at four ends.

Recently, various techniques have been proposed regarding the waterproof structure of a mobile terminal. This is because the mobile terminal is easy to get into a space where water or other liquids are accommodated, as users can easily carry it. If moisture or other foreign matter penetrates into the inside of the mobile terminal, moisture or other foreign matter may interfere with the flow of an electric signal inside the mobile terminal or cause a short circuit. In addition, since the internal parts of the mobile terminal are made of fine electronic parts, even if moisture or other foreign matter infiltrates in a small amount, the parts may be corroded or premature aging may be promoted.

In order to maximize the output area of the display part and minimize the bezel area, the waterproof tape was attached between the front window and the frame in the upper and lower areas of the mobile terminal and between the display part and the frame in the right and left areas. Some of the waterproof tapes are attached to the back surface of the front window and some of the waterproof tapes are attached to the back surface of the display.

In order to solve this problem, there is a method in which a space is provided between disconnected waterproof tapes to inject connection seals. However, since it takes a long time to cure, productivity is deteriorated and defects And a lot of problems.

The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity thereof without mechanical contact using an electromagnetic force or an infrared ray. The proximity sensor 141 may be disposed in the inner region of the mobile terminal 100 wrapped by the touch screen as described above or in proximity to the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

The control unit 180 may include a gesture detection unit and a coordinate transformation unit. The gesture detection unit detects the touch gesture from the touch sensor. The touch gesture includes all the touch operations originating from the touch sensor. If the mobile terminal 100 does not provide a touch function, it detects a user command input through an input unit such as a mouse. The gesture detection unit manages the touch sensor and includes an application program interface (API) that allows the user to easily use the touch gesture in the application. An API is an interface that controls the functions provided by an operating system or programming language for use in an application. The gesture detection unit receives a user command for executing the camera control application through the API, and receives a user command for controlling the activated application.

The coordinate transformation unit receives the coordinate input by the user command from the gesture detection unit, and generates a position change value of the touch input based on the coordinate. If the user performs a touch on a specific object, the coordinates of the point where the touch is input are extracted. When the user performs a drag operation, the coordinates on the drag path are extracted at regular intervals or intervals. The coordinate transformation unit can grasp the direction and distance in which the drag is performed through the extracted coordinates, and converts the direction and the distance to the value where the position of the object should be changed.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

A gyro sensor is a sensor that measures the change of orientation of an object that is rotating. The gyro sensor can estimate the amount of rotation of an object by inversely estimating the position of the origin by using a gyro effect generated when the object rotates. There are various types such as a mechanical type which rotates directly on three axes, a MEMS type tuning fork type using Coriolis force, and an optical type which uses a difference in arrival time of a laser. In general, small-sized devices that can be carried by the user or are easy to use are equipped with the smallest MEMS-type gyroscope sensor.

The acceleration sensor senses the dynamic force such as acceleration, vibration, and shock, and can sequentially detect the motion state of the object. A piezoelectric type that detects the electric charge generated when a force is applied to a piezoelectric element to obtain an acceleration, a coin type in which a conductor detects an electromotive force generated in proportion to its velocity when moving in a magnetic field to obtain an acceleration, And detection model and acceleration model.

Since the gyro sensor and the acceleration sensor determine the position of the watch-type mobile terminal 100, the gyro sensor and the acceleration sensor can be collectively referred to as a position sensor.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The contents input by the first and second operation units 123a and 123b can be variously set. For example, the first operation unit 123a receives a command such as a menu, a home key, a cancellation, a search, and the like, and the second operation unit 123b receives a command from the first or second sound output unit 152a or 152b The size of the sound, and the change of the display unit 151 to the touch recognition mode.

On the other hand, a rear input unit 123c may be provided on the rear surface of the terminal body as another example of the user input unit 123. [ The rear input unit 123c is operated to receive a command for controlling the operation of the mobile terminal 100, and input contents can be variously set. For example, commands such as power on / off, start, end, scrolling, and the like, the size adjustment of the sound output from the first and second sound output units 152a and 152b, And the like can be inputted. The rear input unit 123c may be implemented as a touch input, a push input, or a combination thereof.

The rear input unit 123c may be disposed so as to overlap with the front display unit 151 in the thickness direction of the terminal body. For example, the rear input unit may be disposed at the rear upper end of the terminal body such that when the user holds the terminal body with one hand, the rear input unit can be easily operated using the index finger. However, the present invention is not limited thereto, and the position of the rear input unit 123c may be changed.

When the rear input unit 123c is provided on the rear surface of the terminal body, a new type of user interface using the rear input unit 123c can be realized. In addition, the above-described touch screen or rear input unit 123c replaces at least a part of the functions of the first operation unit 123a provided on the front surface of the terminal body so that the first operation unit 123a is not disposed on the front surface of the terminal body The display unit 151 can be configured as a larger screen.

Meanwhile, the mobile terminal 100 may be provided with a fingerprint recognition sensor for recognizing the fingerprint of the user, and the controller 180 may use the fingerprint information sensed through the fingerprint recognition sensor as authentication means.

When the battery 191 is detachably attached to the terminal body, the rear cover may be detachably coupled to the rear case 102.

FIG. 2 is a view showing a first embodiment of a mobile terminal 100 having a curved display portion 151, and FIG. 3 is a cross-sectional view taken along the line A-A and B-B in FIG. The size of the display unit 151 becomes larger and the size of the bezel located around the display unit 151 becomes smaller. In recent years, in order to reduce the size of the bezel in the vertical direction, the display unit 151 is extended upward to a portion excluding the upper part of the audio output unit 152a and the camera 121a to maximize the size of the display unit 151 I can raise it.

In addition, an organic light emitting diode (OLED) display which does not require a backlight can be used as the material of the display unit 151 is diversified. When the organic light emitting diode display is used, the thickness of the mobile terminal 100 can be reduced and the curved surface can be realized because the thickness thereof is thin. In particular, when the display unit 151 is disposed on the curved surface, the display unit 151 having a larger size can be mounted.

The display unit 151 according to the present invention is arranged to be bent at both ends in the first direction by using the organic light emitting diode display so that the display unit 151 having the maximum size in the size of the first direction of the mobile terminal 100 is mounted . However, the organic light emitting diode display may be curved in one direction, such as paper, but curved in the overlapped portion when curved surfaces are formed in two directions.

Accordingly, the organic light emitting diode display includes a curved surface portion 1512 which forms a flat flat portion 1511 in the middle portion and curved at both ends in the first direction without forming a curved surface in the second direction perpendicular to the first direction . The first direction may be the left and right direction in the drawing, the second direction may be the up and down direction in the drawing, and the upper and lower direction may be the first direction and the second direction may be the left and right direction depending on the embodiment. Hereinafter, the first direction is represented by the left and right second directions, and the upper and lower directions are represented by the same reference numerals.

The case 101 supporting the display unit 151 on the rear surface of the display unit 151 may have a curved surface at the left and right ends when the display unit 151 has the curved surface portion 1512 at the left and right ends. 3B is a cross-sectional view of BB of FIG. 2, showing a display portion 151 having a curved surface portion 1512 bent in a first direction and a first edge portion bent in a first direction at left and right ends in a shape corresponding thereto 221 are shown.

Even though the display unit 151 has no curved surfaces at the upper and lower ends, the front surface of the case 101 may also have curved surfaces at the upper and lower ends so that all four ends may include curved surfaces. The window 200 covering the display unit 151 and forming the front surface of the mobile terminal 100 may have a shape corresponding to the shape of the front surface of the display unit 151 and the case 101.

Conventionally, a flat glass is bent to form a curved window. However, this method can only form the window 200 having a constant thickness, and the curved surface portion 1512 can not be formed in both the first direction and the second direction . However, the present invention can be manufactured by taking the window 200 in a mold, and thus the window 200 having the curved surface in the second direction as well as the curved surface in the first direction and the complex curved surface can be manufactured. The curved surfaces of the left and right sides of the window 200 and the case 101 may be formed in the first and second edge portions 200 and 200, (221), and curved surfaces of the upper and lower portions are referred to as a second edge portion (222).

When both the first edge portion 221 and the second edge portion 222 include a curved surface, the corner portions of the window 200 and the case 102 are formed by combining a curved surface in the first direction and a curved surface in the second direction, A third edge portion 223 having a curved surface is formed. The number of the first edge portions 221 is two, the number of the second edge portions 222 is two, and the number of the third edge portions 223 is four. The width of the first edge portion 221 and the width of the second edge portion 222 may be equal to each other. In this case, the third edge portion 223 may also have the same width as the first edge portion 221, 3 edge portions 223 of the first substrate.

The display unit 151 includes a flat portion 1511 at a flat center portion of the window 200 and a curved portion 1512 extending in a horizontal direction at the flat portion 1511. The curved portion 1512 extends from the first edge portion 221 of the window 200 ). 2, in order to reduce the sizes of the upper and lower bezels, the upper and lower ends of the display unit 151 are disposed at the boundaries between the second edge portion 222 and the flat portion of the window 200 . That is, the width of the second edge portion 222 and the size of the bezel (a) of the upper portion and the bezel of the lower portion may be the same. At this time, the width of the bezel b in the left and right direction is smaller than the width of the first edge portion 221 .

In this case, however, in the design for reducing the size of the bezel in the upper and lower portions, the display portion 151 is positioned 1513 on the complex curved surface portion 223. 3A is a cross-sectional view taken along line A-A of FIG. 2, in which the display portion 151 is located on the complex curved surface portion 223, but the display portion 151 is folded.

4 is a view showing a second embodiment of a mobile terminal 100 having a curved display, and Fig. 5 is a cross-sectional view of C-C and D-D of Fig. In order to solve the above problem, the display unit 151 may be spaced apart from the second edge unit 222 and spaced apart from the complex curved surface by a predetermined distance e as shown in FIG. 5 (a) is a cross-sectional view of CC, FIG. 5 (b) is a cross-sectional view of DD, and the cross-sectional view of DD is the same as that of the BB of the above-described embodiment, and the sectional view of CC does not overlap with the complex curved surface portion 223 The problem that the display unit 151 is folded can be solved. However, as shown in Fig. 4, there is a problem that the size of the upper bezel c becomes larger (the size of the right and left bezels d is the same).

6 is a view showing a mobile terminal 100 having a curved display of the present invention, and Fig. 7 is a cross-sectional view of E-E and F-F of Fig. The present invention can reduce the size of the upper bezel and prevent the display unit 151 from being overlapped with the second edge portion 222 and the third edge portion 223 by using the first edge portion 221 of the window 200, The width and the curvature of the two edge portions 222 may be different from each other, so that the area of the third edge portion 223 can be minimized.

Since the first edge portion 221 overlaps with the curved surface portion 1512 of the display portion 151, the width of the second edge portion 222 can be minimized while the third edge portion 223 has a width It will decrease.

When the window 200 is directly manufactured in the mold as described above, the thickness of the window 200 may vary as shown in FIGS. 7A and 7B. The shape of the front surface of the window 200 and the shape of the back surface are not formed so that the front surface is flat to the end portion and the back surface has the curved surface, the first edge portion 221 and the second edge portion 222 are formed . The thicknesses of the first edge portion 221 and the second edge portion 222 may be changed by making the curvatures of the front surface and the back surface of the first edge portion 221 and the second edge portion 222 different from each other.

If the first edge portion 221 and the second edge portion 222 of the window 200 are formed thicker than the flat middle portion, the screen is further enlarged due to the lens effect, and the curved surface portion 1512 of the display portion 151, Even if it is bent in the direction of the back surface of the terminal, it can be seen to protrude in the front direction.

7 (a), since the display unit 151 does not overlap the third edge unit 223, the display unit 151 does not include the curved surface in the second direction, and as shown in FIG. 7 (b) And a curved surface portion 1512 bent in the first direction at the left and right end portions. In addition, since the size of the second edge and the third edge is reduced, the display unit 151 can be further extended in the vertical direction, and the size of the upper bezel f can be reduced.

As described above, the mobile terminal 100 of the present invention includes not only the first edge portion 221 including the curved surface at the left and right ends but also the second edge portion 222 including the curved surface at the upper and lower ends, And a window 200 structure capable of reducing the size of the bezel of the display device.

The thickness of the window 200 of the first edge portion 221 may be increased to provide a lens effect and the shape of the back surface of the window 200 is determined according to the shapes of the display portion 151 and the case 102, The shape of the entire surface of the window 200 can be freely formed, and the degree of freedom of design can be increased.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
