Embodiment Construction

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the method for repairing defective display provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] Figure 5 A flow chart of a maintenance method for displaying defects provided by Embodiment 1 of the present invention, such as Figure 5 As shown, the method includes:

[0041] Step 101 , detecting a display defect of the display panel.

[0042] Specifically, the display panel can be detected to detect a display defect of the display panel.

[0043] Step 102 , repairing the part of the structure that shows the defect, so that the size of the remaining structure that shows the defect is smaller than the inspection standard value.

[0044] Specifically, buring repairs can be performed on partial structures that display poorly. Preferably, the size of the remaining structure can be the diame...

Abstract

The invention discloses a method for maintenance against display badness.The method comprises the steps of detecting display badness of a display panel; and maintaining part of the structure subject to display badness, so as to make the size of the remaining structure subject to display badness be smaller than a checked standard value.In the technical scheme, the display badness of the display panel is detected, part of the structure subject to display badness is maintained so as to make the size of the remaining structure subject to display badness be smaller than the checked standard value, and thus the maintenance is performed against the display badness to a degree of being acceptable by clients.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a repair method for defective display. Background technique [0002] In the field of display technology, there are two types of dot defects: one is pixel defects, and the other is foreign matter defects in cells. Among them, defective pixels mean that all parts of the entire pixel are bright or dark, that is, defective pixels are divided into bright spots or dark spots, and customers have requirements for the number of bright spots and dark spots; foreign matter defects are usually bad spots with irregular shapes, The dead point will not occupy the entire pixel, and the customer has requirements for the diameter D of the foreign matter. The difference between the above-mentioned defective pixels and defective foreign objects lies in whether the bright spots occupy the entire pixel. [0003] figure 1 It is a schematic diagram of highlights in the prior art, such as figure 1 A...
