Array substrate and flexible display panel

Abstract

The embodiment of the invention discloses an array substrate and a flexible display panel. The array substrate comprises a flexible substrate, a first buffer layer located on the flexible substrate and a second buffer layer, wherein the first buffer layer comprises a plurality of first protrusions, and any two adjacent first protrusions are filled with a flat layer therebetween; the second bufferlayer is located at the side, which is away from the flexible substrate, of the first buffer layer, the second buffer layer comprises a plurality of second protrusions, any two adjacent second protrusions are filled with a flat layer therebetween, and the projection of each second protrusion at least covers part of the clearance between the two adjacent first protrusions in the direction perpendicular to the flexible substrate. According to the array substrate provided by the embodiment of the invention, the internal stress of each buffer layer is optimized through interrupted lamination of each buffer layer under the condition that the total thickness of the buffer layers is slightly changed, so that the bending stress range of a product in a corresponding bending area when being bent isenabled to be restricted within a certain area, the buffer layers are enabled to be stressed in a staggered manner, and the cracking probability of the buffer layers is reduced.

Description

technical field [0001] Embodiments of the present invention relate to flexible display technologies, and in particular to an array substrate and a flexible display panel. Background technique [0002] Active matrix OLED (AMOLED) is a self-luminous display device, which can obtain better picture quality in terms of brightness, color, contrast, viewing angle and response time compared with active matrix liquid crystal display. AMOLED can use flexible substrate materials for flexible displays. Flexible AMOLED has the advantages of making display products lighter, thinner, bendable and less prone to breakage. At present, among the flexible AMOLED display screens, PI (Polyimide, polyimide) is mostly used as the main material of the flexible substrate in the flexible AMOLED. [0003] Such as figure 1 As shown, the flexible AMOLED includes a PI layer 10 , a silicon oxide layer 11 , a silicon nitride layer 12 , a thin film transistor array 13 and an organic light emitting layer 14...
