Problems solved by technology

[0003] After the organic light-emitting diode display is manufactured, it is usually necessary to conduct a series of reliability tests on the display screen. Usually, the ball drop test is used to test the impact resistance of the screen. The phenomenon of stress surge may cause display abnormalities, especially for flexible screens. When it is subjected to an instantaneous impact, due to the absence of a hard protective layer, the stress increases sharply, which is more likely to cause black spots, bright spots, and colorful spots in the display area. defect

Abstract

The invention relates to a display panel and a display device. The display panel includes an array substrate and a light emitting structure arranged on the array substrate. The light emitting structure includes a first electrode, an organic light emitting layer formed on the first electrode, and a second electrode. The organic light emitting layer includes pixels and a pixel defining layer arranged between adjacent pixels. The light emitting structure further comprises a plurality of support columns and a plurality of buffer structures. Each support column is independently disposed on a surface of the pixel defining layer facing the second electrode, and each buffer structure is correspondingly disposed on a surface of the support column remote from the pixel defining layer. The display panel and the display device can effectively reduce the damage to the luminescent structure layer on the supporting pillar when the display panel is subjected to external impact, can effectively disperse and absorb the instantaneous increased stress on the display panel, increase the impact resistance of the screen, achieve the purpose of protecting the film layer structure under the impact of external force and improve the stress diffusion ability.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display, also known as organic electroluminescent display, is a new type of flat panel display device, due to its simple preparation process, low cost, low power consumption, high luminance, It has the advantages of light and thin volume, fast response speed, and easy realization of color display, large-screen display, and flexible display, etc., and has broad application prospects. [0003] After the organic light-emitting diode display is manufactured, it is usually necessary to conduct a series of reliability tests on the display screen. Usually, the ball drop test is used to test the impact resistance of the screen. The phenomenon of stress surge may cause display abnormalities, especially for flexible screens. When it is subjected to an instant...
