Title: PIXEL MATRIX PERIPHERAL COMPENSATION SYSTEM, METHOD THEREOF, AND DISPLAY SYSTEM
Abstract:
A pixel matrix peripheral compensation system, a method thereof, and a display system are provided. The peripheral compensation system comprises a grid scan driver module (200), a column data driver module (300), and a compensation module (400). The compensation module (400) is connected to M column pixel units (101) by means of M column feedback signal lines respectively, and is used to detect an electrical characteristic change of a pixel matrix (100) to send a second display signal to the pixel matrix (100) to perform compensation on each pixel unit (101). Addition of a first display signal and the second display signal in the pixel units (101) is realized, accurate gamma correction is performed on the first display signal, the structure is simple, and the number of bits of a first digital-to-analog module (301) and the number of bits of a second digital-to-analog module (401) are also small. If analog domain addition is adopted, a high-voltage analog adder can be replaced by a medium-voltage or low-voltage adder.
