Pixel charging method of liquid crystal display panel

Abstract

The invention provides a pixel charging method of a liquid crystal display panel. Each pixel unit is defined by a gate line and two data line. The liquid crystal display panel uses an hG-2D driving mode in which two adjacent gate lines can be simultaneously activated, the signal of pixel units in each column is simultaneously provided by two data lines, and all pixel units on two adjacent gate lines can be charged simultaneously. A relative charge mode is characterized in that every two adjacent gate lines are divided into a group; each group of the gate lines is activated for two times; the first time is pre-charging time, the second time is actual charging time; certain time is arranged between two pulses; the charging time of each pixel unit is defined as T, the actual charging time is defined as t, the T = the pre-charging time + t and the interval time of two pulses is t. In the hG-2D driving mode, a phenomenon of insufficient charging or erroneous charging is prevented while charging time is doubled by adding the pre-charging time and changing a pre-charging driving mode.

Description

technical field [0001] The present invention relates to the driving mode of hG-2D driving in the liquid crystal panel, in particular to the grid driving mode which can double the charging time. Background technique [0002] As large-size, high-resolution panels become more and more mainstream, the problem of insufficient charging is also becoming more and more prominent. At present, the commonly used methods to solve the problem of insufficient charging include Gate bilateral input, pre-charging, etc. [0003] figure 1 A graph of the relationship between resolution, frame rate and charging time, such as figure 1 As shown, as the resolution or frame frequency increases, the charging time becomes shorter and shorter, and the problem of insufficient charging becomes more prominent. [0004] figure 2 It is a schematic diagram of a 64.5-inch LCD panel, such as figure 2 As shown, the high-resolution large-size panel adopts the Gate bilateral input method to solve the proble...

AI Technical Summary

Problems solved by technology

So, when using the Figure 5-7 Although the hG-2D driving method shown can improve the above problems, the charging time is still not long enough, and the phenomenon of wrong charging will still occur under severe screen conditions

[0010] Furthermore, in order to pursue a high aperture ratio, the line width of the gate line and data line is further refined, and the charging problem will be more serious at this time.
