Abstract

The invention discloses a liquid crystal display panel, a driving method thereof, and a display device. The liquid crystal display panel includes a plurality of gate lines and a plurality of data lines, wherein the plurality of gate lines and the plurality of data lines are crossed to form a plurality of pixel units which are arranged in an array, the gate lines are divided into a first group of gate lines to a n-th group of gate line, the number of the first group of gate lines to the n-th group of gate lines is identical, and the n is a natural number greater than or equal to 2; a control unit which is connected to a gate driver, and is used for controlling a scanning driver to successively open the first group of gate lines to the n-th group of gate lines while a close down action is executed, wherein the opening timing sequence of the n-th group of gate lines delays Delta t than the opening timing sequence of the n-1-th group of gate lines, the Delta t = CV / Ion, the C is capacitance of the pixel units, the V is on-state voltage of the pixel units, and the Ion is on-state current of the pixel units. The invention further discloses a driving method thereof and a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel, a driving method thereof and a display device. Background technique [0002] The display driving architecture of thin film transistor-liquid crystal display (TFT-LCD) is as follows: figure 1 Shown: When starting up, the power supply circuit (Power-IC) outputs the high-level voltage VGH and timing signal XON for driving the scanning line to the scanning line driving circuit (Gate DriverIC) after receiving the high-level starting voltage VCC. The Gate Driver IC outputs the VGH signal to each scanning line in turn, and turns on the TFT switch of each row of pixels, so that the corresponding pixels receive the data (Data) signal voltage, thereby displaying the screen. [0003] TFT-LCD is a voltage-holding display device, and each pixel needs to hold a certain amount of charge during the screen display period. After the TFT-LCD is turne...

AI Technical Summary

Problems solved by technology

The larger the Igh, the easier the VGH wiring around the TFT-LCD panel will be damaged

The surge current has the following problems: the higher the high level VGH of the scanning line, the greater the current Igh flowing into the scanning line through the TFT; the larger the size of the TFT-LCD panel, the greater the Igh; the higher the resolution of the TFT-LCD panel, Igh bigger

Changing the wiring of the array substrate, the development and verification cost of TFT-LCD is very high
