Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0030] The terms 'first', 'second', etc. in the present invention may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first control could be termed a second control, and, similarly, a second control could be termed a first control, without departing from the scope of the present invention. Both the first control and the second control are c...

Abstract

The invention provides a pixel driving method and device. The method comprises the steps of detecting whether a received picture to be displayed is a reloaded picture or not; if the picture to be displayed is the reloaded picture, converting the picture to be displayed into a corresponding gray scale picture according to a preset conversion rule; generating a data wire signal according to data information of the gray scale picture so as to drive each sub pixel to display the gray scale picture. The pixel driving method has the advantages that the problem that too much heating is caused since a source electrode driving chip displays the reloaded picture can be effectively avoided; meanwhile, heat radiation fins do not need to be attached on the source electrode driving chip by the method; the manufacturing efficiency of a liquid crystal display is not influenced.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a pixel driving method and device. Background technique [0002] With the development of liquid crystal displays and people's pursuit of high-definition and other display effects, some liquid crystal displays with high resolution and high frame frequency have appeared on the market, such as liquid crystal displays with a resolution of 4096×2160 and a frame frequency of 120 Hz . However, high resolution and high frame rate will cause serious heating problems of the data driver chip, especially in the case of displaying heavy screens, the heat of the data driver chip is more serious, and the higher the resolution and frame rate, the higher the temperature of the data driver chip. The fever gets worse. At present, the physical cooling method is mainly used, that is, a heat sink is pasted on each data driver chip to increase the heat dissipation area of ​​the...
