Abstract

The embodiment of the invention discloses a display panel. According to the display panel, a plurality of first shock insulator columns are distributed according to a first preset rule, so that the first shock insulator columns are in one-to-one correspondence with adjacent first sub-pixel openings, and the first sub-pixel openings are formed in at least two directions around the adjacent first shock insulator columns; in other words, the first shock insulator columns are arranged in different directions of the first sub-pixel openings, and the positions of the pixel openings correspond to the positions of the openings of the mask plate, so that when the mask plate is staggered, all the first shock insulator columns are prevented from sliding into the opening positions of the mask plate at the same time, and when one shock insulator column slides into the opening position of the mask plate, the other shock insulator column can play a supporting role, so that the shock insulator column sliding into the opening position of the mask plate is prevented from being scratched, the probability of generating fine particles is further reduced, and packaging failure or abnormal display of the display panel is avoided.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] Organic light-emitting diode display (OLED, Organic Light-Emitting Diode) is widely used because of its advantages such as high luminous efficiency and fast response speed, such as Figure 1 to Figure 2 As shown, manufacturing an OLED display panel mainly includes the steps of sequentially forming an array substrate 110, a pixel definition film layer 120, a spacer support column 130, a light-emitting function film layer 140, and an encapsulation film layer. In the process of forming the light-emitting functional film layer 140, it is necessary to attach a mask structure such as a fine metal mask 150 (FMM, Fine Metal Mask) to the spacer support column 130, so as to realize the alignment of the spacer support column 130 with the fine metal mask. The support of the mask plate 150 is then formed by vapor deposition of luminescent functional...
