Abstract
The application discloses a flexible display panel and a flexible display screen. The flexible display panel includes: a flexible device, including a flexible substrate, a thin film transistor array layer formed on one side of the flexible substrate and arranged in sequence, an anode layer, an organic light-emitting layer, a cathode layer, and an encapsulation layer, and At least one protective layer is formed on the surface of the flexible device, including: a protective film and an elastic layer, and the elastic layer is located on a side of the protective film away from the flexible device. The flexible display panel and the flexible display screen including it can enhance the elastic recovery capability of the flexible display panel, expand the maximum bending degree of the flexible display panel, and thus improve the ability of the flexible screen to resist external impacts.
Description
technical field [0001] The present application relates to the field of display technology, in particular to flexible display panels and flexible display screens. Background technique [0002] With the development of display technology, flexible display devices are more and more widely used. Existing flexible display devices usually use flexible materials as substrates, such as polyimide (PI), due to the bendability of flexible substrates, plus organic light-emitting devices fabricated on flexible substrates, and in organic The light-emitting device is used as a thin film encapsulation layer that blocks water and oxygen, and the flexible display screen made by these laminated structures can be bent very well, thereby realizing the bendable function of the display screen. However, when the display screen is bent beyond a certain degree, the flexible display screen undergoes irreversible deformation, resulting in creases or deformation. Like this, the outward appearance and t...
