Curved surface display panel correction method and system,

Abstract

The invention discloses a curved surface display panel correction method and system. The curved surface display panel correction method comprises steps of providing a curved surface display panel andan optical sensor, photographing the curved surface display panel through the optical sensor, obtaining position information of an image default compensation point of the curved surface display panelaccording to a collected image, obtaining corrected position information of the image default compensation point, calculating an image default position compensation value of the curved surface displaypanel through a processing module according to the obtained position information of the image default compensation point, storing the image default position compensation value into a time sequence control module and assembling the time sequence control module with the curved surface display panel. As a result, the curved surface display panel correction method and system can correctly find the position of the compensation point in the curved surface display panel, performs correct default compensation on the curved surface display panel under a curved surface state and improves quality of a product of the curved surface display panel.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a correction method and system for a curved display panel. Background technique [0002] With the development of liquid crystal display (LCD) towards lighter, thinner and larger, due to some uncontrollable factors in the actual manufacturing process, the physical characteristics of the LCD display panel are different, resulting in more than one pixel. Within the range of, the phenomenon of uneven brightness when displaying pure grayscale images, which is called the Mura phenomenon of image defects in the industry. [0003] The image defect Mura phenomenon has become a bottleneck restricting the development of LCD. By improving the process level or improving the purity of the material, the probability of the occurrence of the image defect Mura phenomenon can be reduced. For the LCD display panel that has been manufactured, its physical characteristics have been finalized. In o...

Problems solved by technology

At present, curved LCD TVs are becoming more and more popular among the public, but after the panel is bent from a flat state to a curved state, the liquid crystal in it will be squeezed by the bending stress of the glass and other unpredictable image defects Mura ( It does not exist in the flat state of the panel, but it is added after bending), so the defect mura cannot be repaired in the flat state of the panel, and then the panel is bent into a curved surface. The only way is to repair the defect mura compensation in the state of the curved panel

[0005] The image defect mura compensation and repair methods in the industry are all based on the panel being in a flat state, because there is a difference in the display area of ​​the panel captured by the camera in the flat state and the curved state, and the flat length in the curved state is smaller than that in the flat state, so It is not possible to directly use the existing planar image defect mura compensation repair method to calculate the defect mura compensation value of each area of ​​the panel in the curved surface state, and it is necessary to develop an image defect mura phenomenon compensation method suitable for the curved surface panel
