3D (Three Dimensional)-mode color cast improving method

Abstract

The invention provides a 3D (Three Dimensional)-mode color cast improving method, which comprises the steps of: 1, correction of analog / digital conversion; 2, gamma correction; 3, verification of just noticeable difference, wherein the gamma correction comprises 2D-mode gamma correction and 3D-mode gamma correction, and the 3D-mode gamma correction comprises color correction of 3D-mode color cast and correction value memory management. Compared with the prior art, the 3D-mode color cast improving method disclosed by the invention has the advantages that by means of the color correction of the 3D-mode color cast and the correction value memory management, the repeated gamma correction and the verification of the just noticeable difference under the 3D mode are avoided, and thus, the gamma correction and the verification of the just noticeable difference only need to be carried out under the 2D mode. Accordingly, the 3D-mode color cast problem can be improved effectively, the time for the gamma correction and the verification of the just noticeable difference is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a manufacturing method of a display device, in particular to a manufacturing method for improving 3D color shift of a display device. Background technique [0002] In recent years, with the continuous advancement of display technology, users have higher and higher requirements for display quality (such as image resolution, color saturation, etc.) of the display. However, in addition to high image resolution and high color saturation, displays capable of displaying 3D stereoscopic images have also been developed in order to meet the needs of users for viewing real images. [0003] At present, 3D stereoscopic display technologies can be roughly divided into stereoscopic (stereoscopic) in which observers need to wear specially designed glasses to watch, and auto-stereoscopic (auto-stereoscopic) in which the observer directly watches with naked eyes. But in the glasses-type stereoscopic display technology, there will be a color sh...

Problems solved by technology

[0004] In the prior art, in order to improve the color shift problem in 3D mode, it is necessary to perform Gamma Alignment in both 2D and 3D modes. When it is necessary to correct video signals with two different color temperatures and four different color gamuts, You need to do 8 sets of gamma values ​​in 2D mode and 8 sets of gamma values ​​in 3D mode, which will double the processing time of the Gamma Alignment System (Gamma Alignment System), and the JND Check System (minimum perceivable Poor system) inspection time is relatively doubled, which directly affects the production efficiency of the factory
