[0027]The display function layer 300 includes a thin film transistor 310 , a flat layer 320 , an anode 330 , an emission definition layer 340 , a light emitting layer 350 , a cathode 360 ​​, an organic encapsulation layer 370 , and an encapsulation protection layer 380 , which are sequentially stacked. Wherein, the thin film transistor 310 can be a common thin film transistor in the field, and it is not limited. The planarization layer 320 is used to planarize the thin film transistor 310 , which facilitates the deposition of subsequent film layers. The anode 330 and the cathode 360 ​​can be a metal material, or a transparent electrode material, specifically, selected according to the actual situation, for example: one of metals or metal compounds such as Ag, IZO, ITO, Mo, Al, etc. one or a combination of several. The luminescence defining layer 340 adopts a hydrophobic material or obtains a hydrophobic surface by means of heating or the like. The light-emitting layer 350 is...

Abstract

The invention discloses a display panel and a reinforcing method thereof, and a display device. The display panel comprises a substrate; at least one buffer layer arranged on one side of the substrate; a display function layer arranged on one side, far away from the substrate, of the buffer layer; a blocking function layer which is arranged on the side, away from the buffer layer, of the display function layer and covers the outer side face of the display function layer; and an adhesive layer arranged on the outer side surfaces of the substrate and the buffer layer. The problem that a thinned glass substrate is prone to generating microcracks in the cutting process can be solved, so that the edge strength of the flexible display panel is improved, and the curling reliability of the flexible display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a strengthening method thereof, and a display device. Background technique [0002] Flexible OLEDs have the advantages of thinness, bendability, low power consumption, and high PPI, and have broad application prospects in smart home appliances and wearable devices. For flexible OLED TVs, the mechanical strength requirements for curling are very high. Generally, 100,000 times of curling tests are required. Therefore, high requirements are placed on the structure and material strength of flexible panels. [0003] At present, there are two production schemes for large-size flexible OLED display panels. One is to coat polyimide (PI) material on rigid glass to form a flexible substrate, and then sequentially form a TFT layer, an OLED layer and a flexible substrate on the PI flexible substrate. For the flexible packaging layer, the rigid glass and the PI fl...
