Problems solved by technology

[0004] Considering that it takes a long time to configure the preset parameters for Mura repair, many LCD panel manufacturers do not configure the preset parameters for Mura repair on the production line, and scrap the defective LCD panels directly, causing a lot of waste

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, a unique Mura repair architecture for the secondary development of LCD panels is characterized in that it includes an LCD panel connected to each other and a timing control module, and an electrically erasable programmable read-only module connected to the timing control module. Memory 1 and EEPROM 2.

[0029] The timing control module has a general input / output interface.

[0030] The general input / output interface includes two settings, one is set to not perform mura repair, and the other is set to perform mura repair; the initial setting is not to perform mura repair.

[0031] The EEPROM 1 stores all other data except the Mura repair; the EEPROM 2 stores the Mura repair parameters.

[0032] Such as figure 2 As shown, a unique Mura repair method for the secondary development of liquid crystal display p...

Abstract

The invention discloses an exclusive Mura restoration framework for secondary development of an LCD panel; the exclusive Mura restoration framework comprises mutually connected the LCD panel and a time sequence control module, and an electrically erasable programmable ROM 1 and an electrically erasable programmable ROM 2 connected with the time sequence control module. The time sequence control module comprises a general input / output interface having two setting modes, wherein one mode is to perform Mura restoration, the other mode is not to perform Mura restoration, and the initial setting is not to perform the Mura restoration. The exclusive Mura restoration framework can carry out secondary development for substandard products LCDs selected by a LCD factory, thus preventing resource waste.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a unique Mura repair framework for secondary development of liquid crystal display panels. Background technique [0002] Current liquid crystal display products mainly use direct-type LED backlight technology or side-type LED backlight technology to illuminate the liquid crystal panel to realize the display of the picture. When the brightness of the LED is uneven, the LED light cannot be evenly illuminated on the LCD panel, and Mura with uneven brightness appears on the screen (Mura refers to the moiré phenomenon caused by uneven brightness of the display); The different distances between the display unit and the LED will also lead to uneven LED light on the LCD panel and Mura appearing on the screen, which will affect the display effect of the LCD product and reduce the viewing quality of the screen. [0003] In the traditional process, the liquid crystal display panel adjusts a...
