Problems solved by technology

However, due to the adaptability of human vision to the environment, whenever the brightness of the environment changes, the light parameters such as the brightness of the display device previously set cannot be optimally matched with it, and the device needs to be manually re-set the relevant parameters to achieve the best display effect; Otherwise, when viewing the LCD monitor for a long time, it will aggravate the fatigue of the eyes, thus affecting the eyesight
Generally, people do not manually adjust the light parameters of LCD devices at any time, so in order to see the display content clearly under different ambient light, the relevant light parameter values ​​are often adjusted to a relatively large value. When the ambient light is weak, the power consumption will be affected. A certain waste, but also has a certain impact on the service life of the backlight

Embodiment Construction

[0012] In Fig. 1, a liquid crystal panel (1) and its backlight driving module (2) and a video processing and liquid crystal display driving module (3) constitute the core part of a currently known liquid crystal display product. The video processing and liquid crystal display driving module (3) receives the original video image signal for processing, and makes the liquid crystal panel display images through the liquid crystal display interface (6) (such as TTL, LVDS, analog RGB, etc.). The main control microcontroller (4) controls the work of the video and liquid crystal display driver module (3) through some control ports, including the optical parameter control port (10) and the IIC bus (9), and the relevant storage information is stored in the memory device (5 ), due to the non-active light-emitting technology of liquid crystal display, its light source is generated by its backlight part. At present, almost all the backlight parts of the liquid crystal panels provide switch...

Abstract

An intelligent light tuning system of the LCD display adds a light sensitive component, automatically adjusting the liquid phototropism lightness, LCD lightness, contrast, and color value through light sensed to the environment. It can reduce the fatigue to the eye of users; protect the user's eyesight, reducing the power consumption and radiation at certain level, extending the phototropism durability of the liquid.

Description

technical field [0001] The invention relates to an intelligent dimming system for liquid crystal display equipment. Background technique [0002] At present, the backlight of known liquid crystal display devices (such as liquid crystal televisions, liquid crystal displays, notebook computer monitors, portable DVDs, etc.) is constant or manually adjustable, and parameters such as brightness, contrast, and color saturation are also manually adjusted by buttons. However, due to the adaptability of human vision to the environment, whenever the brightness of the environment changes, the light parameters such as the brightness of the display device previously set cannot be optimally matched with it, and the device needs to be manually re-set the relevant parameters to achieve the best display effect; Otherwise, when viewing the liquid crystal display for a long time, the fatigue of the eyes will be aggravated, thereby affecting vision. Generally, people do not manually adjust the...
