AI Technical Summary

Technical Problem

It is difficult for the prior art to effectively drive high-resolution display screens, especially products with 5500*5500 resolution. The output capabilities of a single display driver chip and a backlight driver chip are limited.

Method used

It adopts a display module design, including a display panel, a backlight module and a driving circuit. The display panel is divided into two parts, upper and lower, and is driven by the first and second display driving circuits respectively. The backlight module is driven synchronously with the light sources superimposed on the upper and lower split screens through a matrix light source and a backlight driving circuit, respectively, to realize bilateral driving.

Benefits of technology

It realizes effective driving and brightness compensation for high-resolution products, improves the driving capability of the display module, and is suitable for higher resolution display screens.
