Embodiment Construction

[0046] The present invention provides a method for improving the visual deflection of a display panel, such as figure 1 As shown, the method includes the following steps:

[0047] S1. Measuring the actual tristimulus values ​​of the full gray scale red, green, blue and white under the front view angle and the side view angle when the white balance adjustment is not performed on the display panel, and use these actual tristimulus values ​​as raw data. Here, the tristimulus value can be measured by a color analyzer, and the selected side view angle can be 30 degrees, 45 degrees, 60 degrees, and so on.

[0048] S2. Set the RGB grayscale value of 255 grayscale white; for example, you can set the grayscale value of 255 grayscale white to 255, 254, 254, that is, 255 grayscale white consists of 255 grayscale red, 254 grayscale green and 254 gray scale blue composition.

[0049] S3. Calculate the theoretical RGB gray scale value of the full gray scale white balance according to the set RGB ...

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, and in particular to a method and system for improving the visual deflection of a display panel. Background technique [0002] The VA (Vertical Alignment, vertical alignment technology) display screen has the problem of large visual role deviation of the bus bar, and the color deviation problem under the skin color viewing angle is more serious. To solve such problems, it is often through the design of the display to improve; for example: design the pixels of the display, modify the pixels of the display to 8domain, or use the Tcon (also called logic board, screen driver board, The central control panel is added to improve the viewing angle function for improvement. [0003] The principle of the 8domain solution is to divide the pixels into main pixels and sub-pixels when preparing pixels. The main pixels and sub-pixels will have different areas and voltage ratios, so that the main pixels and ...
