Driving Method of Liquid Crystal Display with Tri-Gate Driving Architecture

Abstract

A driving method of a liquid crystal display having a tri-gate driver architecture. A liquid crystal display having a tri-gate driver architecture comprises multiple sub-pixels arranged in an array; the sub-pixels comprise red sub-pixels, green sub-pixels, and blue sub-pixels; each of the sub-pixels is electrically connected to one scan line and one data line; sub-pixels in each column are arranged according to a preset sub-pixel color sequence from top to bottom repetitively; sub-pixels in each row have the same color. When being driven, the sub-pixels are driven at an interval of every 3N rows sequentially, N being an natural number greater than 1; when 3N rows of sub-pixels in each interval are driven, first, N rows of sub-pixels of a first color are consecutively driven from top to bottom, then N rows of sub-pixels of a second color are consecutively driven from top to bottom, and finally N rows of sub-pixels of a third color are consecutively driven from top to bottom. The driving method of a liquid crystal display having a tri-gate driver architecture can improve the charging rate of a monochromatic image, and eliminate the problems of color cast and uneven displaying of a liquid crystal display caused by undercharging of pixels.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a driving method of a liquid crystal display with a tri-gate driving structure. Background technique [0002] Liquid crystal display is currently the most widely used flat-panel display, and has gradually become a display device with high-resolution color screens widely used in various electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. monitor. The liquid crystal display commonly used at present usually consists of upper and lower substrates and a middle liquid crystal layer, and the substrate is composed of glass and electrodes. If there are electrodes on the upper and lower substrates, displays in vertical electric field mode can be formed, such as twisted nematic (TN, Twist Nematic) mode, vertical alignment (VA, Vertical Alignment) mode, and multi-domain vertical ...

When displaying a monochrome picture, the driving waveform is as image 3 As shown, the Data line is driven by the IC driving voltage provided by the data driving IC. Since the voltage on the Data line is always in a state of high and low changes, the monochrome screen is a heavy-duty screen for the Tri-gate drive architecture. The charging capacity of the pixels Very poor, it is easy to be insufficiently charged, resulting in poor picture display and reduced display quality
