Problems solved by technology

[0005] In the flexible process, OLED devices are generally manufactured on a flexible substrate, and an encapsulation layer is prepared on the OLED device to seal the OLED device and prevent contamination by impurities such as water and oxygen. However, when bending frequently, the bending area is due to Affected by the stress on both sides of the OLED device, the encapsulation layer of the OLED device is easier to break, resulting in deterioration or even damage to the function of the OLED device
After the function of the OLED device deteriorates, the display effect and product life will be greatly affected

Abstract

The invention provides an organic light emitting diode (OLED) substrate and a display device, and belongs to the technical field of display. By the OLED substrate and the display device, the problem that a package layer of a traditional flexible OLED substrate is easy to break can be solved. The OLED substrate is provided with a plurality of display regions and non-display regions, wherein the display regions are encircled by the non-display regions, the OLED substrate comprises a flexible substrate, OLED devices, a pre-package layer and a protection layer, the OLED devices are arranged on theflexible substrate and are corresponding to positions of the display regions, the pre-package layer is arranged on a layer where the OLED devices are located, the protection layer is arranged on thepre-package layer, buffer layers are arranged at positions, corresponding to at least one part of the non-display regions, in the protection layer, and the flexibility of the buffer layers is larger than the flexibility of the protection layer.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an OLED substrate and a display device. Background technique [0002] An organic light emitting diode (Organic Light Emitting Diode, referred to as: OLED) has the characteristic of self-luminescence, and when a current passes through it, the OLED will emit light. With the rapid progress of display technology, semiconductor element technology, which is the core of the display device, has also been greatly improved. For existing display devices, organic light-emitting diodes, as a current-mode light-emitting device, are increasingly being used because of their characteristics such as self-illumination, fast response, wide viewing angle, and the ability to be fabricated on flexible substrates. It is used in the field of high-performance display. [0003] Organic Electroluminescent Display (Organic Electroluminescent Display), with its low power consumption, high color...
