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

The invention provides a liquid crystal display processing method, apparatus and equipment. For each frame of picture, a time controller sends N STV signals corresponding to the frame of picture to one gate driver; the gate drivers control N-time pre breakover of thin film transistors (TFTs) at all rows of a liquid crystal display panel successively according to the N STV signals; before closure of the first pre breakover at an Mth row, N+1th STV signals are sent to the gate drivers; according to the N+1th STV signals, the gate drivers control the N+1th breakover of the TFTs at all rows of the liquid crystal display panel, so that source drivers carry out final charging of storage capacitors at all rows conveniently; and meanwhile, pre charging of the storage capacitors at all rows after pre breakover of the TFTs is carried out. According to the liquid crystal display processing method, before displaying of one frame of picture, charging of the storage capacitors at all rows in the screen is carried out at least twice and thus charging time of the storage capacitors at all rows of the liquid crystal display panel is prolonged, so that the electric quantities at the two ends of the storage capacitors at all rows can meet the requirement of picture displaying to the greatest extent and thus the picture quality of the liquid crystal display device is improved.

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 (Thin Film Transistor, referred to as TFT) type LCD, thin film diode (Thin Film Diode, referred to as TFD) type LCD, ultra-thin clear (Ultra Fine Bright, referred to as UFB) type LCD, etc. LCD is an active matrix type liquid crystal display. It is a plate 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. The voltage until the next frame is updated, and the amount of electr...
