Problems solved by technology

[0004] However, during the bending process of the current flexible display device, there is also bending stress between the cathode layer and the organic light-emitting layer, as well as the anode layer and the organic light-emitting layer, which leads to the failure of the cathode layer and the organic light-emitting layer after multiple bending of the flexible display device. , and peeling between the anode layer and the organic light-emitting layer, cracking or fracture in the cathode layer and the anode layer, which affect the light-emitting performance of the flexible display device

Abstract

The invention provides a flexible display panel and a flexible display device. The flexible display panel comprises a plurality of light emitting units, wherein each light emitting unit comprises a first electrode layer, a pixel layer and a second electrode layer which are stacked in sequence; the flexible display panel further comprises a pixel limiting layer used for separating the pixel layers;and a bonding layer is arranged between at least one of the first electrode layer and the second electrode layer and the pixel layer, wherein the bonding layer is a transparent conductive adhesive layer. According to the flexible display panel, in the bending process of the flexible display device, stripping or separating between a negative electrode layer and a positive electrode layer of a functional membrane layer and an organic light-emitting layer can be effectively avoided, and a breakage or cracking in the interior of the functional membrane layer can be avoided, so that the light-emitting performance of the flexible display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a flexible display device. Background technique [0002] With the rapid development of electronic technology, people's requirements for the foldable performance of electronic devices such as mobile phones and computers are gradually increasing. Among them, flexible organic light-emitting diodes (Organic Light-Emitting Diode, referred to as: OLED) are widely used in In flexible display devices such as terminal equipment and wearable equipment. [0003] Existing flexible display devices generally include a flexible substrate, a thin film transistor layer, an anode layer, an organic light-emitting layer, a cathode layer, and a thin film encapsulation layer that are sequentially stacked. After the flexible display device is electrified, holes and electrons are combined in the organic light-emitting layer under the electric field drive between t...
