Liquid crystal module display correction method and equipment

Abstract

Embodiments of the present invention provide a liquid crystal module display correction method and equipment, the liquid crystal module includes at least two liquid crystal layers, the method includes inputting a predetermined grayscale driving signal to each pixel in the fault area, and determining the fault area The actual brightness of the internal liquid crystal module; the fault area is located in the first liquid crystal layer; according to the actual brightness and the predetermined gray scale driving signal, determine the compensation value of each pixel in the fault area; load the compensation value to In the driving signal of each pixel in the correction area corresponding to the fault area, so that the liquid crystal module displays normally; the correction area is located in the second liquid crystal layer, and the second liquid crystal layer and the first liquid crystal layer are different liquid crystal layers. The embodiment of the present invention can compensate the display defects of the liquid crystal layer in the faulty area by adjusting the brightness of the liquid crystal layer in the non-faulty area, thereby reducing the maintenance cost and shortening the maintenance cycle compared with replacing the entire liquid crystal module.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of liquid crystal display, and in particular to a method and equipment for correcting the display of a liquid crystal module. Background technique [0002] Liquid Crystal Display (LCD) is a flat panel display device with excellent features such as high definition, thin profile, light weight, and low power consumption. It is widely used in thin TVs, computer monitors, and electronic billboards. [0003] Currently in the LCD industry, whether it is In-Plane Switching (IPS) or Vertical Alignment liquid crystal (VA), when the LCD panel has a display problem with poor lines, it is due to poor lines. It is a hardware problem, so it cannot be compensated by backlight or software, and the display problem can only be solved by replacing the LCD panel or display module. [0004] However, the maintenance cost of the above solution is high, the maintenance cycle is long, and logistics costs an...

Problems solved by technology

[0003] Currently in the LCD industry, whether it is In-Plane Switching (IPS) or Vertical Alignment liquid crystal (VA), when the LCD panel has a display problem with poor lines, it is due to poor lines. It is a hardware problem, so it cannot be compensated by backlight or software, and the display problem can only be solved by replacing the LCD panel or display module

[0004] However, the above solution has high maintenance cost, long maintenance cycle and will generate logistics and storage fees, which will damage the interests of consumers and manufacturers.
