Embodiment Construction

[0025] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0026] A kind of demura hardware realization method that saves hardware storage space of the present invention comprises the following steps,

[0027] Step S1, image capturing;

[0028] Step S2, according to the mura degree of the captured image, determine the size of the required compensation block;

[0029] Step S3, calculating the compensation value of each compensation block;

[0030] Step S4, compensate the image.

[0031] In the step S1, the image capture is realized by taking images with a CCD camera.

[0032] In the step S2, the mura degree of the captured image is determined by analyzing the pixel brightness and color distribution characteristics of the captured image, and then identifying the mura degree according to an algorithm.

[0033] In the step S3, calculating the compensation value of each compensation block is to ge...

Abstract

The invention relates to a demura hardware implementation method capable of saving hardware storage space. The method includes: Step S1, capturing an image; s2, according to the mura degree of the captured image, judging the size of the required compensation block; step S3, calculating a compensation value of each compensation block; and S4, compensating the image. According to the method, the hardware space of the demura can be saved.

Description

technical field [0001] The invention relates to a demura hardware realization method which saves hardware storage space. Background technique [0002] Such as figure 1 As shown, each sub-pixel (sub-pixel) of AMOLED has a different compensation value, which requires a large hardware space; [0003] (1), the demura hardware space of prior art: [0004] Among them, m*n is the screen resolution (panel resolution), [0005] is the offset width (per subpixel). [0006] (2), demura hardware implementation steps of the prior art: [0007] STEP-1: Image capture. [0008] STEP-2: Calculate the compensation value of each sub-pixel. [0009] STEP-3: Compensate the image according to the compensation value. [0010] Wherein, each sub-pixel in the prior art has a different compensation value, which will occupy a relatively large hardware space. [0011] It can be seen that in the prior art of hardware implementation of AMOLED dumra, each sub-pixel has a different compensation ...
