LIQUID CRYSTAL DISPLAY PANEL WITH REPAIRED HOT PIXEL AND METHOD FOR REPAIRING HOT PIXEL Russian patent published in 2018 - IPC G02F1/13 

Abstract RU 2663270 C1

FIELD: images forming devices.

SUBSTANCE: invention relates to a liquid crystal display panel with a repaired hot pixel and a method for repairing a hot pixel. Liquid crystal display panel comprises a matrix substrate that contains a pixel after repair. Pixel comprises a main pixel block and a sub-pixel block that receive data signals controlled by the first scanning line to have the same voltage; charge sharing unit. Sub-pixel block contains hot pixels in the sub-pixel after repair, the drain electrode of the thin-film transistor is disconnected from the antenna, the antenna is disconnected from the sub-pixel electrode, the antenna is electrically connected to the electrode of the main pixel, the sub-pixel electrode is electrically connected to the common bus; and the charge sharing unit is disconnected from the main pixel block and the sub-pixel block.

EFFECT: high image quality.
