Embodiment Construction

[0044] Specifically, such as figure 1 As shown, in the special-shaped display area, the opening area 01 of the pixel defining layer used to define the light emitting area of ​​the sub-pixel is arranged in steps. figure 1 In the illustration, the shape of each opening area 01 is a hexagon surrounded by a solid line as an example. Correspondingly, the hollow area 021 of the FMM used to make the light-emitting functional layer 02 of the sub-pixel is consistent with the shape and size of the opening area 01 of the pixel definition layer, that is, the two overlap each other. Due to the shadow area (Shadow) in the evaporation process, the pattern of the final light-emitting functional layer 02 is larger than the hollow area 021 of the FMM. figure 1 The hexagon surrounded by dotted lines in the diagram indicates the pattern of the produced light-emitting functional layer 02 . Since the opening area 01 of the pixel definition layer is arranged in steps at the ideal edge 03 of the sp...

Abstract

The invention discloses an electroluminescent display panel, a manufacturing method and a display device. An opening region of a pixel defining layer defines the sub-pixel light emitting region. By changing the shape of the opening region of the edge of an irregular display region, the area of the opening region with the irregular edge is smaller than the area of an opening region in the standardshape with the same light emitting color sub-pixel. By changing the opening region with the irregular edge along with the ideal edge of the irregular display region, the outer side of the ideal edge is free from the opening region, so a sawtooth displaying problem of the irregular display region is thoroughly eliminated. The light emitting functional layer of the sub-pixel fully covers the corresponding opening region, so it can be ensured that the shape region with uncontrollable thickness during evaporation is out of the opening region with irregular edge, so brightness of the sub-pixel of the irregular display region will not be affected to cause the poor displaying.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electroluminescence display panel, a manufacturing method thereof and a display device. Background technique [0002] At present, the screens of common display devices, such as monitors, televisions, mobile phones, tablet computers, etc., are usually regular rectangles. With the development of display technology, special-shaped display screen will be the trend of display design in the future, and the sawtooth in the special-shaped display area is one of the important factors affecting the special-shaped display. [0003] Usually, eliminating the sawtooth display problem in the special-shaped display area can be improved by adjusting the brightness of the pixel corresponding to the sawtooth position by compensating and adjusting the internal operation of the driver chip (IC). This kind of software compensation technology is immature and cannot meet the design requirements of ...
