Embodiment Construction

[0051] The specific methods, steps, features and effects of the pixel array driving method according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0052] The following descriptions mainly focus on TFT liquid crystal displays, but those skilled in the art should know that this driving method can be applied to any similar array display driving device.

[0053] The thin film transistor type liquid crystal display is mainly composed of a thin film transistor array substrate, a color filter array substrate and a liquid crystal layer, wherein the thin film transistor array substrate is composed of a plurality of thin film transistors arranged in an array, and each thin film transistor is configured composed of one pixel. Each pixel contains two pieces of pixel electrodes, one of which is electrically coupled to a common potential, and the other is coupled to the data controlled by the thin film tra...

Abstract

The driving method is applicable to pixel array. The pixel array includes multiple pixel groups in same row, and at least one pixel group includes multiple pixels. In the method, pixel electrode potential of each pixel in a pixel group is in potential in same phase, and pixel electrode potentials of each pixel in adjacent two pixel groups are in potentials in inverted phase. Only one grid line drives two adjacent pixels in row. First pixel in a pixel group and a pixel in adjacent column are driven by same grid line. Being as high opening rate, the driving mode for pixel array provides even brightness and stable gray graph.

Description

technical field [0001] The present invention relates to a driving device suitable for liquid crystal displays, in particular to a driving method for a pixel array with a high aperture ratio (Aperture Ratio) and a pixel array driving technology that can provide a stable gray-scale picture (Grey-scale Picture). . Background technique [0002] Generally speaking, liquid crystal displays are distinguished according to driving methods, which can be divided into passive driving and active driving liquid crystal displays. The liquid crystal display used in common mobile phones is a passive driving liquid crystal display. Due to the serious capacitive coupling (Capacitor Coupling) phenomenon of this type of liquid crystal display, the image quality is low, such as residual image, poor contrast and slow response rate. and other phenomena, and it is usually driven by multitasking, which is much more complicated than that of active-driven LCDs. Therefore, if this type of LCD is to ach...
