Abstract

The invention provides a display verification method. The display verification method comprises the following steps: S1, selecting a picture range; S2, carrying out accumulation after comparison; S3,judging whether the cumulative number in the step S2 is greater than or equal to a threshold value or not, if yes, ending after the output display is normal, and if not, performing the next step S4; and S4, outputting an error prompt and ending.

Description

technical field [0001] The invention relates to a display verification method, in particular to a display verification method using an FPGA verification algorithm for a display panel. Background technique [0002] Field programmable gate array (field programmable gate array, FPGA) is mainly used for signal processing and various high-speed analog simulations. It is also an effective means to verify the design of complex chips and chip designs through FPGA verification, which can make up for The lack of software simulation simulation reduces verification time. [0003] Display panels such as liquid crystal display panels and light-emitting diode (Light-emitting diode, LED) display panels, the pixel structure of the picture image is composed of red, green and blue sub-pixels. In order to realize image display, generally through the pixel The structure conversion algorithm obtains the gray scale of each sub-pixel. At present, the display panel uses FPGA to verify the pixel st...
