Problems solved by technology

[0003] Existing technology implementation: the current demura scheme is based on the front view. After the demura treatment panel, the mura phenomenon has been greatly improved from the front view, but the corrected panel can still be seen from the side view. To the more serious mura, which greatly affects the overall effect of demura

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0029] Figure 1 ~ Figure 3 Shown are three specific embodiments of the system of the present invention for obtaining demura from different viewpoints.

[0030] figure 1 The schematic diagram of Embodiment 1 of the present invention shown in the present invention uses multiple sets of optical systems 2 to simultaneously collect mura information of different viewing angles of the LCD TV 1, and the number of optical systems 2 used depends on the fineness of the viewing angles to be compensated. The main...

Abstract

The invention provides a demura implementation method based on the side view angle of a liquid crystal television. The method comprises the following steps: (1) acquiring mura information of differentview angles; (2) according to the mura information of the different view angles, generating demura compensation lookup tables LUTs under the different view angles; and (3) improving the demura effects of the different view angles according to the demura compensation lookup tables LUTs under the different view angles. With the method provided by the invention, the serious mura phenomenon existingwhen the liquid crystal television is watched from the side view angle is improved, and the method is suitable for compensating luminance mura and chrominance mura.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a demura implementation method based on the side view angle of a liquid crystal television. Background technique [0002] LCD TVs have the advantages of small size, low power consumption, and high resolution, and are widely used in daily life. However, its production process is complicated. During the manufacturing process, various display defects will inevitably occur. The most common ones are uneven chromaticity caused by abnormal CF, abnormal display brightness caused by uneven brightness of the backlight module, etc. These display defects are called It is mura phenomenon. These factors will cause visual discomfort and seriously affect the quality of the LCD panel. In order to improve mura defects, de-mura technology has been widely used. The de-mura technology improves the display uniformity of LCD TVs by changing the gray scale of the display screen according to the brig...
