Embodiment 1
[0036] This embodiment provides a method for repairing bright spot pixel defects of a display panel. A shielding layer is set at the corresponding position to shield the sub-pixels with bright pixel defects and make them opaque.
[0037] It can be seen that the method for repairing bright pixel defects of the display panel is simple and easy, and can repair all sub-pixels with bright pixel defects. Compared with the repair method using laser irradiation in the prior art, the repair speed is fast and the efficiency is high .
[0038] This embodiment also provides a display panel, which includes sub-pixels with bright pixel defects, and the display panel includes a color filter substrate, an array substrate, and polarizers respectively arranged on one side of the color filter substrate and one side of the array substrate.
[0039] Such as figure 1 As shown, a shielding layer 3 is provided on the polarizer 2 disposed on the side of the color filter substrate and / or disposed on ...
Embodiment 2
[0042] Such as figure 2As shown, this embodiment provides a method for repairing bright pixel defects of a display panel, including the following steps:
[0043] s101. Using a white light source to light up the display panel to be repaired and control it to display a black image, and then obtain the position of the sub-pixel with bright pixel defects on the display panel.
[0044] s102. Set up a shielding layer on the polarizer disposed on the side of the color filter substrate and / or on the side of the array substrate corresponding to the positions of the sub-pixels with bright pixel defects, so as to shield the sub-pixels with bright pixel defects Sub-pixel and make it opaque. The thickness of the shielding layer is suitable to make the sub-pixels with bright pixel defects opaque.
[0045] Wherein, the shielding layer is made of a curable liquid capable of shielding the sub-pixels with bright pixel defects and making them opaque.
[0046] Preferably, the material of the ...
Embodiment 3
[0052] The difference between this embodiment and embodiment 2 is:
[0053] In the method for repairing bright spot pixel defects of a display panel and the display panel described in this embodiment, the shielding layer is a film capable of shielding the sub-pixels with bright spot pixel defects and making them opaque.
[0054] Preferably, the sticking film is made of negative photoresist. The material of the negative photoresist includes propylene glycol methyl ether acetate (PGMEA), carbon black, existing additives and the like.
[0055] Preferably, the thickness of the sticking film is in the range of 1-3 μm.
[0056] Other methods, structures, and functions in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
