Problems solved by technology
Since the general image format is RGB, and the pixel structure of the AMOLED screen is RGBG, the two do not match
[0004] When the AMOLED module is turned on for testing, the module needs an RGBG pixel structure. During the test, there are special circumstances that may temporarily add built-in pictures (RGB format input), so format conversion (RGB-RGBG) is required to reach the point The purpose of the screen, in the existing technology, in order to facilitate the development of OLED modules, the general use of dedicated host computer software for pixel structure conversion, for some specific pictures simply using the host computer configuration is not flexible and efficient, and the instant verification capability is insufficient

The invention discloses a chip for image conversion, an RGB-RGBG pixel structure conversion device and method. The chip for image conversion comprises a bus control module, a frame buffer module, an RGB time sequence generation module, a frame processing module, an algorithm conversion module and an image output module, wherein the frame buffer module reads RGB image data from a memory according to a control instruction of the bus control module and transmits the RGB image data to the RGB time sequence generation module; the RGB time sequence generation module generates a time sequence signalrequired by a display module to be tested according to the display resolution parameter of the display module; the frame processing module associates the time sequence signal with the RGB image data,and transmits the associated time sequence signal and RGB image data to the algorithm conversion module; the algorithm conversion module performs RGB-RGBG format conversion on the RGB image data to generate an RGBG image to be tested; and the image output module outputs the image to be tested to the display module for display according to the time sequence signal.
Description
technical field [0001] The invention relates to the technical field of module display and testing. More specifically, it relates to a chip for image conversion, an RGB-RGBG pixel structure conversion device and method. Background technique [0002] With the continuous development of science and technology, digital image processing technology has penetrated into every field of science and technology, and people cannot do without image processing in modern social life. Active matrix organic light-emitting diodes (AMOLED) have many advantages such as wide color gamut, low power consumption, thinness, flexibility, etc., and have broad application prospects in smart phones and smart displays. [0003] AMOLED displays generally adopt an RGBG pixel structure. Since the general image format is RGB, and the pixel structure of the AMOLED screen is RGBG, the two do not match. [0004] When the AMOLED module is turned on for testing, the module needs an RGBG pixel structure. During t...
