Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In the pixel repairing method provided by the present invention, when a sub-pixel in the pixel array is defective to form a defective sub-pixel, the anode of the defective sub-pixel is connected to the adjacent normal sub-pixel by setting a connecting line to the signal receiving end of the defective sub-pixel. The anodes of the sub-pixels are connected in series, and combined with the brightness compensation technology, the defective sub-pixel can be repaired, so...

Abstract

The invention relates to a pixel repairing method and a manufacturing method of an organic light-emitting display panel, and the method comprises the steps: enabling a signal receiving end to disconnect a defective sub-pixel when the sub-pixel in a pixel array has a defect and forms the defective sub-pixel; the anodes of the defective sub-pixels and the anodes of the adjacent normal sub-pixels are connected in series by arranging the connecting lines, and the defective sub-pixels can be repaired by combining a brightness compensation technology, so that the defective sub-pixels can emit light normally, the display brightness is consistent with that of the adjacent normal sub-pixels, pseudo-normalization of the defective sub-pixels is realized, and the display quality of the defective sub-pixels is improved. According to the organic light-emitting display panel, the metal wiring density in the pixel array can be reduced, the situation that defect normal repair cannot be carried out due to insufficient pixel space is avoided, the number of defect points in the organic light-emitting display panel product is reduced, and the product yield is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a pixel repairing method and a manufacturing method of an organic light-emitting display panel. Background technique [0002] In order to reduce the number of dark spots in the pixel array, the current mass-produced large-size organic light-emitting display panel (OLED) products usually adopt the design of reserved anode bridges in the pixel structure design, that is, in the adjacent two sub-pixels with the same color An anode bridge trace is designed between them. One end of the anode bridge trace is connected to the anode of a sub-pixel a, and the other end is connected to the anode overlap area of ​​another adjacent sub-pixel b of the same color but not connected to the anode of the sub-pixel b. on. When a defect (such as a dark spot) occurs in the sub-pixel a and needs to be repaired, the connection between the anode bridge wiring and the anode lap area of ​​th...
