Problems solved by technology

[0004] However, as far as the prior art is concerned, since the twisting time of the liquid crystal unit is longer than the response time of the display screen, when the display screen has changed the image screen, the previous screen still has no time to recover and update the screen, so smearing will occur. If the response time is prolonged, it will cause the display screen to lag, especially when the user is engaged in animation games or watching movies and animations.

Abstract

This invention discloses a driver of a display screen, which integrates the drive circuits of the display screen and the backlight module set to make the image display time sequence of the screen to match up with the bright and dark sequence of the lumen scale of the variance period of the backlight module set so as to increase the quality of images displayed by the screen.

Description

technical field [0001] The invention relates to a driving device of a display screen, in particular to a driving device applied to a display screen equipped with back light source illumination and capable of improving the image quality of the display screen. Background technique [0002] The liquid crystal display (LCD), which utilizes liquid crystal unit molecules to twist the image, is widely used in various electronic products. After adding the audio and video playback function, the dynamic image quality of the liquid crystal display becomes the first choice for users to choose the liquid crystal display. main judging factor. [0003] At present, when image processing is performed on LCD screens, it is often found that the color of the LCD screen is not realistic enough, and the main reason for this is the influence caused by "reaction time" and "contrast". The response time referred to here refers to a The time required for a liquid crystal cell to go from emitting ligh...
