Display that automatically adjusts the viewing angle

The present invention relates to a display, and more particularly to a display that automatically adjusts the viewing angle.

Liquid crystal displays have become the mainstream technology of today's TV screens because of their advantages of power saving, low radiation, and light size. However, since liquid crystals are directional materials, they must be optically angularly dependent, allowing users to observe obliquely. The brightness will vary from vertical to vertical, and it will mean that the oblique contrast changes. Generally, the larger the oblique angle is, the smaller the contrast (CR) is. The basic viewing angle is defined in contrast. There is still a maximum oblique angle of 10. In fact, the viewing angle of a liquid crystal display is good or bad. There should still be the worst acceptable degree according to factors such as color shift (Gray Level Inversion) and Grayscale Inversion (Transmittance Uniformity). Defined to the corner, but the current definition of the perspective is still based on contrast.

Therefore, although there have been many techniques for wide viewing angles, in reality, there is still a problem of image quality degradation when the user obliquely views the display screen, but the subjective feelings of the human eyes are different, and the worst image quality that each individual can perceive. It is also the same, the only thing that can be ensured is that the image quality of the user from the front is optimal. Therefore, a computer device capable of adjusting the viewing angle of the display has been proposed. As shown in FIG. 1 , FIG. 1 is a perspective view of a computer device that can adjust the viewing angle of the display, which includes a display 10 , a rotating device 11 , a base 12 , a keyboard 13 , and a shake . The lever 14 and the computer main body 15 use a stepping motor as the turning device 11 and are disposed on the display 10, and the stepping motor is controlled in a wireless or wired manner in conjunction with the rocker 14 to adjust various angles of the display 10. , can be adjusted to the appropriate perspective with different users. In addition, most of the home monitors still need to manually adjust the monitor base. Some people have proposed using the remote control to control the viewing angle of the screen. However, these methods are still not convenient for modern users, and the manual adjustment process is extremely easy. Damage the fragile panel.

Therefore, the inventor was in the spirit of active invention, thinking about a display that can automatically adjust the angle of the panel according to the remote control or the location of the person. After several studies, the invention was completed.

In view of the above problem of inconvenient adjustment of the display, the present invention provides a display with adjustable viewing angle, comprising: a display panel, a rotating mechanism, a base, a micro control unit, a receiving unit, and a transmitting unit.

To adjust the viewing angle of the display panel. Therefore, in this case, the micro control unit judges the orientation of the remote control signal and drives the rotation mechanism to rotate, so that the display can automatically adjust the appropriate viewing angle according to the position of the remote controller to provide the user with the best viewing quality.

The display panel of the present invention may be a liquid crystal display panel, a plasma display panel, or an organic light emitting diode display panel.

Wherein, the rotating mechanism of the present invention may be a motor.

Among them, the angle of the invention may range from -15° to +15°.

The signal transmitted by the transmitting unit of the present invention may be an ultrasonic signal, an infrared signal or another wireless signal transmission signal, and the above object may also be achieved.

Wherein, the transmitting unit of the present invention can automatically transmit a signal at intervals or can manually transmit a signal.

2 is a schematic diagram of a display with adjustable viewing angle according to a preferred embodiment of the present invention. FIG. 2 shows a display panel 20, such as a liquid crystal display panel, a plasma display panel, or an organic light emitting diode display panel. A rotating mechanism 21, such as a motor, is coupled to the display panel 20 for rotating the display panel 20 within an angular range, such as -15° to +15°; a base 22 carries the rotating mechanism 21; and a micro control unit 25 The inside of the display panel 20 is electrically connected to the rotating mechanism 21; a receiving unit 24 is located inside the display panel 20 and electrically connected to the micro control unit 25; and a transmitting unit 23, such as a remote controller.

FIG. 3 is a schematic structural diagram of a system for automatically adjusting a viewing angle according to a preferred embodiment of the present invention. FIG. 4 is a flowchart of automatically adjusting a viewing angle according to a preferred embodiment of the present invention, wherein the transmitting unit 23 is used at intervals. Automatically transmitting a signal (step 31), the receiving unit 24 receives the signal transmitted by the transmitting unit 23 (step 32), such as an ultrasonic signal, an infrared signal or other wireless signal transmission signal, and transmits the signal to the micro control unit 25, the micro control unit After estimating and judging the orientation of the signal (step 33), it is compared with the current orientation to determine whether it is necessary to automatically adjust the display panel angle (step 34). If necessary, the micro control unit 25 generates an electrical signal to the rotating mechanism 21 to drive the rotation. The mechanism 21 is rotated at an appropriate angle (step 35), such as -15° to +15°, to automatically adjust the viewing angle of the display panel 20. Therefore, according to the technical content of the above preferred embodiment of the present invention, the display panel 20 can automatically adjust an appropriate viewing angle according to the position of the remote controller to provide the user with the best viewing quality.

5 is a flow chart of manually adjusting a viewing angle according to another embodiment of the present invention, in which the transmitting unit 23 is manually transmitting a signal (step 51), and the receiving unit 24 receives the signal transmitted by the transmitting unit 23 (step 52), for example, The ultrasonic signal, the infrared signal or other wireless signal transmission signal, the receiving unit 24 transmits the signal to the micro control unit 25, and the micro control unit 25 estimates and determines the orientation of the signal (step 53), and then generates an electrical signal to the rotating mechanism. 21, the driving rotation mechanism 21 is rotated by an angular range (step 54), for example, -15 to +15 to adjust the viewing angle of the display panel 20. Therefore, according to the technical content of the above another embodiment of the present invention, the user can manually operate the remote controller to adjust the viewing angle of the display panel 20 to provide satisfactory viewing quality.

Please refer to FIG. 6a-c for a schematic diagram of automatically changing the angle of the display with the remote controller according to a preferred embodiment of the present invention. According to the habit of watching TV, the remote control 23 is usually placed near the viewer's hand for easy access.
