Abstract

The invention provides an electronic device for realizing pixel jitter calculating based on a graphics processor. A central processor receives the image data, corresponding to a first image code, transmitted by the electronic device, a display displays the image data corresponding to a second image code, the graphics processor converts the image data corresponding to the first image code into the image data corresponding to the second image code and applies a pixel jitter matrix group to generate a corresponding pixel jitter signal, the pixel value of each pixel in each frame is driven to sequentially compare with the threshold of the corresponding matrix of the jitter matrix group, and the intensity of the pixel value is increased when the pixel value is larger than the threshold of the matrix. The invention further provides a method for realizing pixel jitter calculating based on the graphics processor. By the electronic device and the method, the problem that tire marks or blocks exist in LCD image display in the prior art is solved, and display quality is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electronic device and method for realizing pixel shake calculation based on a graphics processor. Background technique [0002] Liquid crystal displays (LCDs) are commonly used as screens or displays for a variety of electronic devices, including consumer electronics such as televisions, computers, and handheld devices such as cellular phones, audio and video players, gaming systems, and the like. Such LCD devices generally provide flat panel displays with relatively thin and low weight packages, which are suitable for use in a variety of electronic products. Furthermore, such LCD devices typically use less power than Kirby's display technology, making them suitable for use in battery powered devices, or other environments where it is desirable to minimize power usage. LCD devices typically include thousands (or trillions) of image components, ie pixels, arranged in rows and...
