Problems solved by technology

It can be seen from the figure that after the Mura area is adjusted to be consistent with the normal area at the front viewing angle, the gamma coefficient curve may not be consistent with the normal area due to the characteristics of the Mura area in the large viewing area area, which will seriously affect the quality of the flat display panel and reduce the Flat panel display panel production yield

Embodiment Construction

[0034] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0035] see Figures 5 to 7 , the present invention provides a compensation method for a large viewing angle Mura area of ​​a flat display panel, comprising the following steps:

[0036] Step 1. Provide a flat display panel, the flat display panel includes several main pixels, and the flat display panel includes a Mura area and a normal area.

[0037] Each of the main pixels includes: a red sub-pixel, a green sub-pixel and a blue sub-pixel, such as Image 6 shown. Both the mura area and the normal area include several main pixels.

[0038] Step 2. Two or more main pixels in the Mura area are used as a group of Mura area brightness adjustment units.

[0039] In this step, the Mura area is divided into several brightness adjustment areas, eac...

Abstract

The invention provides a compensation method for a flat display panel large-viewing-angle Mura area. The compensation method for the flat display panel large viewing angle Mura area includes the following steps: 1. providing a flat display panel which comprises a plurality of main pixels, wherein the flat display panel comprises a Mura area and normal areas; 2. setting two or more main pixels in the Mura area as a group of Mura area brightness control unit; 3. providing a drive circuit which drives the flat display panel, wherein the drive circuit provides a plurality of gamma voltages; and 4. utilizing the drive circuit to apply two or more types of gamma voltages on the plurality of main pixels in each group of Mura area brightness control unit to enable a gray scale coefficient of the front-viewing-angle and large-viewing-angle Mura to approach to a gray scale coefficient of the normal area, and the brightness of the whole flat display panel is consistent. According to the compensation method for the flat display panel large-viewing-angle Mura area, the gray scale coefficients of the Mura area at various viewing angles are enabled to approach to the gray scale coefficient of the normal area, and flat display panel production yield is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for compensating a large viewing angle Mura area of ​​a flat display panel. Background technique [0002] Nowadays, with the vigorous development of science and technology, the types of information products are introduced to meet the different needs of the public. Most of the early monitors were Cathode Ray Tube (CRT) monitors. Due to their bulky size and high power consumption, the radiation produced was harmful to the health of users who used the monitors for a long time. Therefore, the displays on the market today will gradually be replaced by liquid crystal displays (Liquid Crystal Display, LCD). [0003] With the development of science and technology and the needs of people's material life, the size of flat-panel displays is getting bigger and bigger, especially liquid crystal displays, which have developed from small sizes such as 14 inches and 17 inches to 40 in...
