PERIPHERAL COMPENSATION SYSTEM AND METHOD FOR PIXEL MATRIX, AND DISPLAY SYSTEM

摘要

Provided are a peripheral compensation system and method for a pixel matrix (100), and a display system. The peripheral compensation system comprises: a row scanning driver (200), a compensator (400) and a column driver (300), wherein the column driver (300) comprises a display signal generation module (301), and the display signal generation module (301) comprises a first digital-to-analogue conversion module (311) having a gamma correction function, a second digital-to-analogue conversion module (312) and a first analogue addition module (313). Therefore, while performing precise gamma correction on a digital original signal, the peripheral compensation system has a simple structure, and the number of bits of the first digital-to-analogue conversion module is small; and a correction operation can also be performed during the display of a display system, so that the refresh frequency of compensation information can be increased to the maximum extent.
