A method and system for improving viewing angle deviation of a display panel

Abstract

The invention provides a method and a system for improving the visual role deviation of a display panel. The method comprises the following steps: S1, when the white balance adjustment is not carriedout on a measurement display panel, the actual tristimulus values corresponding to the full gray scale red, green, blue and white under the front view angle and the side view angle are taken as raw data; S2, setting 255 gray-scale white RGB gray-scale value; S3, calculating the theoretical RGB gray scale value of the whole gray scale white balance; S4, calculating the actual color coordinate difference data of the front-view angle and the side-view angle when the display panel displays the image picture under the theoretical RGB gray scale value of the full gray scale white balance; 5, calculating that difference data between the actual color coordinate difference data and the set specification data as the first difference data; S6, judging whether the actual color coordinate difference value satisfies the set specification, if not, adjusting the 255 gray-scale white RGB gray-scale value according to the first difference data, and returning to step S3. The invention can effectively improve the visual role deviation of the display panel, and does not increase the cost of the central control panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method and system for improving viewing angle deviation of a display panel. Background technique [0002] VA (Vertical Alignment, Vertical Alignment Technology) display has the problem of large-view role shift of the busbar, and the problem of color shift in the perspective of skin color is even more serious. For such problems, it is often improved through the design of the display screen; for example: designing the pixels of the display screen, modifying the pixels of the display screen to an 8domain solution, or Tcon (also called logic board, screen driver board, The function of improving the viewing angle has been added to the central control panel) for improvement. [0003] The principle of 8domain’s solution is to divide the pixels into main pixels and sub-pixels when preparing pixels. The main pixels and sub-pixels will have different area and voltage ratios, so...

AI Technical Summary

Problems solved by technology

This solution requires hardware expansion of Tcon, which will increase the cost of Tcon, and through this solution to improve the viewing angle, when the display panel is in low grayscale, there will be flickering problems and poor image quality
