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 OLED substrate and a display device, belonging to the field of display technology, which can solve the problem that the encapsulation layer of the existing flexible OLED substrate is easily broken. The OLED substrate of the present invention has a plurality of display areas and a non-display area surrounding the display areas, and the OLED substrate includes: a flexible base, an OLED device arranged on the flexible base and corresponding to the position of the display area , a pre-encapsulation layer disposed above the layer where the OLED device is located, a protective layer disposed above the pre-encapsulation layer; a buffer layer is disposed in the protective layer and at a position corresponding to at least part of the non-display area, And the toughness of the buffer layer is greater than the toughness of the protective 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...
