Partition driving processing method, processing device and displayer

Abstract

The invention provides a partition driving processing method, a processing device and a displayer. Different kinds of partition compensation and promotion of the simulation reference voltage are carried out through the partition Gamma Table, all-directional Gamma compensation in the perpendicular direction is achieved, the consistent luminance of a picture in the perpendicular direction is achieved, accordingly, the problem of up-and-down picture undercharging picture luminance uniformity caused by the fact that up-and-down signal delay of a 4K2K display screen is large is solved, and the problem of up-and-down crosstalk of the picture under a 3D mode is solved.

Description

technical field [0001] The invention relates to screen display technology, in particular to a partition drive processing method, a processing device and a display. Background technique [0002] In recent years, with the rapid development of screen display technology, revolutionary technologies have appeared again and again, from cathode ray tube (Cathode Ray Tube; CRT for short) to liquid crystal display (Liquid Crystal Display; LCD for short) technology, from cold cathode fluorescent tube ( ColdCathodeFluorescentLamp (abbreviation: CCFL) backlight to energy-saving and thin light-emitting diode (LightEmittingDiode; abbreviation: LED) products, from 2D to 3D technology products, every new display technology update has brought great economic and market benefits to manufacturers. This More and more companies are taking the lead in thinking and preparing for the technology and products of the "post-flat TV era". What is the next generation of revolutionary technology in the disp...

Problems solved by technology

Therefore, the number of pixels (Pixel) in the vertical direction becomes twice that of the 1080p display screen, which increases the number of driving lines on the line, and the equivalent impedance and capacitive reactance of each segment are large, making the initial end (near the driving circuit) One end) and the most terminal (the end far away from the drive circuit) drive signals are very different, so that the signal delay at the upper and lower ends of the picture is relatively large. Specifically, the drive signal at the beginning end is not distorted, so it will be immediately on the rising edge of the drive signal. reach the set driving voltage value, and the final terminal is distorted due to the influence of equivalent impedance and capacitive reactance, so the rising edge of the driving signal does not immediately reach the set driving voltage value, but by a period Due to the delay of time, the charging of the upper and lower images is insufficient, which makes the brightness of the upper and lower images uneven, especially in the 3D state, which makes the crosstalk between the upper and lower images very large

[0006] Therefore, how to solve the defect of uneven brightness caused by insufficient charging of the upper and lower screens of the 4K2K display screen has become an important issue to be solved urgently in the industry.
