Abstract

An embodiment of the invention discloses a public electrode voltage compensation method and device and a time schedule controller, relates to the field of liquid crystal displays, and can solve the problem of display frame pixel gray scale deviation generated by inversion of positive polarity and negative polarity of gray scale voltage. The public electrode voltage compensation method includes: performing statistics on gray scale data of each pixel of a display frame, calculating gray scale deviation ratio between two adjacent lines of pixels, obtaining public electrode voltage compensation signal parameters according to the gray scale deviation ratio, generating positive and negative polarity information of the public electrode voltage compensation signal parameters according to pixel voltage polarity reversal signals, and generating public polarity voltage compensation control signals according to the public electrode voltage compensation signal parameters and the positive and negative polarity of the public electrode voltage compensation signal parameters so as to enable a public electrode generation unit to generate public electrode input voltage with compensating voltage waveform according to the public polarity voltage compensation control signals.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a common electrode voltage compensation method, device and timing controller. Background technique [0002] With the increasing maturity of photoelectric display technology, the application fields of flat panel display devices are becoming more and more extensive. At present, based on its characteristics such as long life, high light efficiency, low radiation, and low power consumption, liquid crystal displays have gradually become the mainstream research direction of display equipment products in recent years. Among them, in order to ensure the normal display of the display screen, the liquid crystal display uses the voltage difference between the common electrode voltage and the gray scale voltage when displaying the pixel gray scale, and uses different voltage differences to represent different gray scales. [0003] However, during the research and development process, t...
