Problems solved by technology

[0002] As an important component of the touch display screen, the touch panel is relatively close to the human body during actual use. However, most of the current displays cannot quickly adjust the brightness. It will be interfered by the strong light of the display, which not only affects the user's operation, but also easily causes damage to the user's body, especially the user's retina. Therefore, it is necessary to improve the traditional touch display screen so that the touch display screen can Automatically adjust the brightness according to the change of the distance between the user and the touch screen, so as to ensure the operation and display of the touch screen

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as Figure 1-2 As shown, a touch display screen for automatic brightness adjustment based on distance detection includes a display device 1, and a dimming module 2, a touch screen 3, and a distance detection module 4 arranged on the side of the display device 1 in sequence. The internal devices of the display device 1 There is a processor 5 and a controller 6 , and the processor 5 , the controller 6 and the control circuit 7 are sequentially connected between the distance detection device 4 and the dimming module 2 .

[0019] The dimming module 2 is a dimming liquid crystal layer.

[0020] The light transmittance adjustment range of the dimming module 2 is 40%-90%.

[0021] The light transmittance of the dimming module 2 decreases as the output voltage of the control circuit 7 increases, and finally becomes translucent.

[0022] The distance detection module ...

Abstract

The invention relates to a touch display screen for automatic brightness adjustment based on distance detection, which comprises a display device, a dimming module, a touch screen and a distance detection module sequentially arranged on the side of the display device; a processor and a controller are arranged inside the display device; the processor, the controller and the control circuit are sequentially connected between the distance detection device and the dimming module. The touch screen for automatic brightness adjustment based on distance detection, through at least two sets of distancedetection modules, As that distance between the user and the display device is reduced, the power supply voltage of the dimming module is increased through the control circuit, so that the light transmittance of the dimming module is quickly adjust, the display brightness of the display device is adjusted, and the influence of the display brightness on the user is avoided.

Description

technical field [0001] The invention relates to the technical field of touch screen equipment, in particular to a touch display screen for automatic brightness adjustment based on distance detection. Background technique [0002] As an important component of the touch display screen, the touch panel is relatively close to the human body during actual use. However, most of the current displays cannot quickly adjust the brightness. It will be interfered by the strong light of the display, which not only affects the user's operation, but also easily causes damage to the user's body, especially the user's retina. Therefore, it is necessary to improve the traditional touch display screen so that the touch display screen can Automatically adjust the brightness according to the change of the distance between the user and the touch screen, so as to ensure the operation and display of the touch screen. Contents of the invention [0003] The object of the present invention is to pr...
