CN105023539A 一种像素矩阵的外围补偿系统、方法和显示系统 有权

一种像素矩阵的外围补偿系统、方法和显示系统
Abstract:
本申请提供一种像素矩阵的外围补偿系统、方法和显示系统，其中外围补偿系统包括：行扫描驱动器(200)、补偿器(400)、列驱动器(300)，列驱动器(300)包括显示信号产生模块(301)，所述显示信号产生模块(301)包括具有伽马校正功能的第一数模转换模块(311)、第二数模转换模块(312)和第一模拟加法模块(313)。本申请对数字原始信号进行了精确伽马校正的同时，结构简单，第一数模转换模块的位数低；本申请还可以在显示系统显示的时候进行校正操作，从而可以极大限度的增加补偿信息的刷新频率。
Abstract(English):

The invention provides a peripheral compensation system and method of a pixel matrix and a display system. The peripheral compensation system includes a row scanning driver (200), a compensator (400) and a column driver (300), wherein the column driver (300) includes a display signal generation module (301), and the display signal generation module (301) includes a first digital-to-analog conversion module (311) having a gamma correction function, a second digital-to-analog conversion module (312) and a first analog addition module (313). While performing precise gamma correction on a digital original signal, the peripheral compensation system is simple in structure, and the number of bits of the first digital-to-analog conversion module is small; and the peripheral compensation system can also perform correction operation during display of a display system, thereby greatly increasing the refreshing frequency of compensation information.
