Example Embodiment

[0041] Reference figure 1 The method for correcting the color difference of the display screen provided by the present invention includes the following steps.

[0042] S1. Draw the color coordinate of the pixel point according to the test image as the target color coordinate, and the color coordinate of the pixel point records the composite three primary colors of each pixel on the screen when the test image is displayed on the display screen.

[0043] In this step, the pixel point is X i Y j Indicates, specifically, X i Y j Represents the pixel points in the jth column on the i-th row on the X-axis and the Y-axis in the measured image. Since the test image is the image to be displayed on the screen, the size of the test image is consistent with the screen, and the pixel point X i Y j The coordinate position of is positioned according to the screen. The three primary colors of each pixel in the target color coordinate, namely the red color value, the green color value and the blue...

Abstract

The invention discloses a display screen chromatic aberration correction method, and includes the steps of: S1. drawing pixel point chromaticity coordinates as target chromaticity coordinates according to a test image; S2. generating an actual measurement image according to the test image, and extracting pixels of a plurality of coordinate points of the actual measurement image; S3. comparing synthesized three primary colors of the extracted points with synthesized three primary colors of corresponding coordinate points in the target chromaticity coordinates, and judging whether chromatic aberration exists; S4. drawing pixel point chromaticity coordinates of the actual measurement image as actual measurement chromaticity coordinates; S5. calculating an chromatic aberration value of corresponding coordinate points of the actual measurement chromaticity coordinates and the target chromaticity coordinates, and generating initial chromatic aberration coordinates; S7. obtaining average deviation coordinates according to the initial chromatic aberration coordinates and contrast chromatic aberration coordinates; and S8. after a subsequent to-be-displayed image is compensated according to the average deviation coordinates, sending the to-be-displayed image after compensation to a screen to be displayed. The display screen chromatic aberration correction method is in favor of unification of standards for screen display chromatic aberration judgment, and guarantees the precision of chromatic aberration compensation of the to-be-displayed image.

Description

Technical field [0001] The invention relates to the technical field of display screens, in particular to a method for correcting the color difference of the display screens. Background technique [0002] With the increasing development of electronic technology, liquid crystal display technology is more and more widely used in people's daily life. At present, in the liquid crystal screen in the prior art, the voltage of each pixel of the liquid crystal screen is fixed during a face-changing display period, so that the liquid crystal molecules can move to obtain a certain light transmittance to display the picture until the next picture period. Different speed-limiting voltages are applied to change the light transmittance of liquid crystal molecules and display different images. This kind of display method will have the problem of image retention when displaying fast-moving pictures, which may cause problems such as picture color crosstalk, and cause problems with the display pic...
