Abstract

The invention relates to the technical field of flexible display, and discloses a flexible displayer and a manufacturing method thereof. The flexible displayer comprises a first flexible substrate, a pixel defining layer and a cathode. The pixel defining layer is made of resin materials. First division walls are provided with protruding structures, and first channels provided with openings deviating from the first flexible substrate and extending along the length direction of the first division wall are formed by the protruding structures. Second division walls are provided with protruding structures, and second channels provided with openings deviating from the first flexible substrate and extending in the length direction of the second division walls are formed by the protruding structures. The parts, directly facing the first division walls, of the cathode are provided with bends corresponding to the first channels, and the parts, directly facing the second division walls, of the cathode are provided with bends corresponding to the second channels. When the flexible displayer is bent along the first division walls or the second division walls, the cathode can release stress borne by the cathode, and the quality of the flexible displayer is improved.

Description

technical field [0001] The invention relates to the technical field of flexible displays, in particular to a flexible display and a preparation method thereof. Background technique [0002] Flexible displays have many advantages, such as easy bending, impact resistance, strong shock resistance, light weight, small size, and more convenient to carry. At present, the main flexible display materials can be roughly divided into three types: electronic paper (or flexible electrophoretic display), flexible OLED and flexible liquid crystal. [0003] The flexible display includes an anode, a pixel defining layer, and a negative electrode. The flexible display has a pixel area and a non-pixel area, and the pixel defining layer has a plurality of horizontal partition walls arranged in parallel and a plurality of vertical partition walls arranged in parallel in the non-pixel area. The partition wall and the vertical partition wall are intersected to separate multiple pixel areas of th...
