Abstract

The present disclosure relates to a flexible display substrate and a flexible display device. The flexible display substrate includes a flexible substrate and a pixel layer. The flexible substrate includes a plurality of opening regions and a plurality of island regions and bridge regions divided by the plurality of the opening regions. The pixel layer includes a plurality of display units which are disposed in the respective island regions one to one. Each of the display units is provided with a first groove. The first groove divides the display unit into a display portion and a dam portion.At least a part of the dam portion is located between the display portion and the bridge region adjacent to the display portion. The flexible display substrate provided by the present disclosure can improve the product packaging reliability.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a flexible display substrate and a flexible display device. Background technique [0002] Organic electroluminescent (OLED) devices have the characteristics of low power consumption, light weight, high brightness, wide field of view and fast response. In addition, one of the most attractive features of OLED devices is the ability to realize flexible display functions, making them widely used in portable Electronic equipment, wearable electronic equipment, vehicle electronic equipment and many other fields. [0003] A flexible OLED device generally includes a substrate, an electroluminescent element on the substrate, and an encapsulation layer on the electroluminescent element. The substrate uses a flexible substrate to realize a flexible display function. However, to realize stretchable display, each island region on the substrate needs to be individually packaged, an...
