Abstract

The invention discloses a display panel drive device and a display panel, the main content of which includes: relying on a drive chip or other software modules in the drive integration unit, integrating a virtual algorithm and a backlight adjustment algorithm in the drive integration unit, Therefore, the algorithms that should be integrated in two independent processing systems are integrated into one drive integration unit, so that one processing system can realize the virtual display function and the backlight adjustment function. On the one hand, it can effectively improve the image information. On the other hand, it avoids additional wiring due to the addition of virtual algorithms or backlight adjustment algorithms.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel drive device and a display panel. Background technique [0002] Virtual display technology is widely used in the field of display technology at present, mainly through pixel sharing, each virtual pixel borrows each sub-pixel in the adjacent virtual pixel to display the color it lacks, and realizes the same display as each original pixel function, thereby increasing the image resolution of the frame to be displayed. The backlight adjustment technology is to calculate the backlight brightness value of the adjusted backlight module according to the brightness information of the detected image of the frame to be displayed, and adjust the backlight module according to the brightness value. The brightness value is adapted to the image information, and the grayscale brightness information of the image matching the brightness of the backlight is determined, and then sen...
