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

Embodiment Construction

[0025] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0026] Such as image 3 As shown, the 3D mode color shift improvement method of a preferred embodiment of the present invention includes:

[0027] Step S101 , analog-digital conversion correction; the video signal corrected by analog-digital conversion is a video signal with a color temperature of 9300K or a video signal with a color temperature of 6500K. After analog-to-digital conversion and correction, four color space conversions are performed on the video signal, which are respectively marked as OFF, SMPTE C, EBU and ITU 709. Wherein, the OFF means not performing color space conversion on the video signal. The SMPTE C, EBU and ITU 709 are respectively converted video signals in corresponding color spaces.

[0028] Step S102, gamma correction; the gamma correct...

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...
