Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0033] It can be seen from the analysis of the background technology that the charging time of the storage capacitors of each row of the LCD panel will be shortened with the increase of the pixels of the liquid crystal panel. It will seriously affect the image quality of the liquid crystal display, mainly because the voltage at both ends of the storage capacitor on each pixel determines the flip angle of the liquid crystal molecules. For this reason, the present invention mainly proposes a liquid crystal display processing method, device and equipment from the perspective of how to increase the voltage at both ends of the storage capacitor on each pixel.

Abstract

A liquid crystal display processing method, device and apparatus. The method comprises: sending, by a timing controller (100) and for each frame, N STV signals corresponding to the frame to a gate driver (133) first; sequentially controlling, by the gate driver (133) and according to the N STV signals, each row of TFTs (135) of a liquid crystal panel to be turned on in advance for N times; sending, before the end of the first advance turn-on of an Mth row, an (N+1)th STV signal to the gate driver (133); and controlling, by the gate driver (133) and according to the (N+1)th STV signal, each row of the TFTs (135) in the liquid crystal panel to be turned on for the (N+1)th time, such that a source driver (134) performs final charging on said row of storage capacitors (136), and at the same time, performs pre-charging on a row of storage capacitors having the TFTs (135) being turned on in advance. In the liquid crystal display processing method, each row of storage capacitors (136) in a screen is charged for at least twice before displaying one frame, and in turn, a charging duration for each row of storage capacitors (136) in the liquid crystal panel is increased, such that charges between both ends of storage capacitors (136) in each row can meet the requirement of displaying a frame as much as possible, thus improving the display quality of a liquid crystal display.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a liquid crystal display processing method, device and equipment. Background technique [0002] Currently, Liquid Crystal Displays (LCD for short) are widely used in desktop computers, mobile phones, televisions, and various office automation and audio-visual equipment. LCD mainly includes: Thin Film Transistor (TFT for short) LCD, Thin Film Diode (TFD for short) LCD, Ultra Fine Bright (UFB for short) LCD, etc. Among them, TFT LCD It is an active matrix type liquid crystal display. It is a flat capacitor composed of two layers of glass substrates sandwiching liquid crystals. The storage capacitance of this capacitor is charged by the TFT embedded in the lower glass plate to maintain the required power of each frame. Voltage until the next frame is updated, and the amount of electricity on the storage capacitor determines the content of the frame. [0...
