Abstract
The utility model relates to a liquid crystal color control device which is characterized by comprising a shift register chip (1), a power circuit (2), a liquid crystal driving chip (3) and an LCD display circuit (4); the power circuit (2) is connected with the shift register chip (1); the liquid crystal driving chip (3) is connected with the shift register chip (1); the LCD display circuit (4) is connected with the liquid crystal driving chip (3); and a photoresistor is arranged in the shift register chip (1). The liquid crystal color control device can automatically control the color and brightness of a liquid crystal display screen, so that the liquid crystal display screen adapts to different environments and facilitates the actual operation of a user.
Description
(1) technical field
The utility model relates to a kind of liquid crystal color control device.
(2) background technology
On the Industry Control regulator cubicle in modern times, the electric equipment products of liquid crystal display are more and more, the technology of LCD is also more and more ripe, LCD is the product that lcd technology and shadow casting technique combine, it has utilized the electrooptical effect of liquid crystal, by the transmissivity and the reflectivity of circuit control liquid crystal cells, thereby produce different gray-levels and coloury image.The main image device of LCD projector is a liquid crystal board, and what liquid crystal board used is active liquid crystal, can be by the brightness and the color of relevant control system control liquid crystal board.Yet traditional LCDs and operating environment have very big related, and when being subjected to the influencing of extraneous light, the demonstration contrast of LCDs is less, has caused display effect relatively poor.In order to reach best display effect, the user will regulate according to the difference of LCDs ambient light and show contrast and brightness, and this has brought very big inconvenience just for the user when practical operation.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of liquid crystal color control device, this liquid crystal color control device can the auto-control LCDs color and brightness, make LCDs adapt to different environment, and made things convenient for user's practical operation.
The purpose of this utility model is achieved in that a kind of liquid crystal color control device, it comprises shift register chip, power circuit, lcd drive chip and LCD display circuit, described power circuit links to each other with the shift register chip, described lcd drive chip is connected with the shift register chip, described LCD display circuit links to each other with lcd drive chip, is provided with photoresistance in the described shift register chip.
The beneficial effect that the utlity model has is:
This liquid crystal color control device can judge that the power of extraneous light comes the color and the brightness of auto-control LCDs by photoresistance, thereby has overcome the weakness that traditional LCDs can not adapt to varying environment.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: shift register chip 1, power circuit 2, lcd drive chip 3, LCD display circuit 4.
(5) embodiment
As figure, the utility model relates to a kind of liquid crystal color control device, it comprises shift register chip 1, power circuit 2, lcd drive chip 3 and LCD display circuit 4, described power circuit 2 links to each other with shift register chip 1, described lcd drive chip 3 is connected with shift register chip 1, described LCD display circuit 4 links to each other with lcd drive chip 3, is provided with photoresistance in the described shift register chip 1.
The utility model liquid crystal color control device is by the size and the angle of the filter of regulator solution intracrystalline portion, transmitting illuminant is arranged to controllable light source, the power of light and then the color of regulating liquid crystal display are judged in the variation of the voltage that produces of the change in resistance by photoresistance again.
Claims (1)
1. liquid crystal color control device, it is characterized in that: it comprises shift register chip (1), power circuit (2), lcd drive chip (3) and LCD display circuit (4), described power circuit (2) links to each other with shift register chip (1), described lcd drive chip (3) is connected with shift register chip (1), described LCD display circuit (4) links to each other with lcd drive chip (3), is provided with photoresistance in the described shift register chip (1).
