Method and apparatus for adjusting gray-scale chromatic aberration for display panel and display device
First Claim
1. A method for adjusting gray-scale chromatic aberration for a display panel, comprising:
- inputting a data signal of a test picture to sub-pixels of the display panel, for causing the display panel to display the test picture;
collecting optical parameters of respective regions in the test picture;
comparing the optical parameter of each region in the test picture with an optical parameter of a standard picture; and
adjusting the data signal inputted to the sub-pixels such that a difference between the optical parameter of each region in the test picture and the optical parameter of the standard picture falls within a predetermined range,wherein the optical parameter comprises a color coordinate and its corresponding brightness;
wherein the method further comprises adjusting a gray-scale color coordinate of the test picture in response to a difference between the color coordinate of each region in the test picture and the color coordinate of the standard picture has an absolute value smaller than a first predetermined threshold.
