Embodiment 1

[0043] See figure 1 , figure 1 A schematic diagram of a pixel arrangement design provided for the prior art. At present, liquid crystal display devices can adopt column inversion (column inversion) driving method and flip pixel (flip pixel) pixel arrangement design at the same time, so the arrangement method of pixels is H-stripe (horizontal stripes), and this arrangement method is used in the display If the screen needs to be turned on for a long time, the drive device will overheat. For example, when the light is turned on for 30 minutes, the measured temperatures of the same position of different COF (Chip On Film, chip-on-film) are 105.2°C, 100.4°C, 105.9°C, 108.2°C, 106.7°C.

Abstract

The invention discloses a pixel data optimization method, a pixel matrix driving device and a display. The optimization method comprises the following steps: acquiring a first pixel data set; obtaining a second pixel data set according to the first pixel data set; obtaining an initial amplitude difference according to pixel data of two adjacent rows of pixels in the second pixel data set; and obtaining pixel output data of the n rows * M columns of pixels according to the initial amplitude difference and a preset threshold. According to the invention, the initial amplitude difference obtained by the pixel data of the two adjacent rows of pixels is compared with the preset threshold value, so that a final pixel gray-scale value to be displayed by each pixel can be adjusted according to a comparison result, and the energy consumption of the driving device can be improved. Therefore, the overheat phenomenon of the COF driving device is improved, and the visual effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of image display, and in particular relates to a method for optimizing pixel data, a pixel matrix driving device and a display. Background technique [0002] With the development of the information society, people's demands on display devices are increasing rapidly. In order to meet this demand, display devices represented by liquid crystal display devices (LCD, Liquid Crystal Display), plasma displays (PDP, Plasma Display Panel), and organic light emitting display devices (OLED, Organic Light Emitting Diode) have been rapidly developed. develop. Among flat panel display devices, liquid crystal display devices are being used more and more widely due to their advantages of low weight, small volume, and low energy consumption. [0003] The liquid crystal display device includes various display modes such as twisted nematic (TN) mode, electrically controlled birefringence (ECB) mode, vertical alignment (Verti...
