Abstract

The invention provides a flexible substrate, a flexible display panel and a manufacturing method of the flexible substrate. The flexible substrate is provided with a bending area and a non-bending area, wherein the non-bending region comprises a first substrate layer, the bending area comprises the first substrate layer and a second substrate layer arranged on one side of the first substrate layer, and a plurality of grooves distributed in an array mode are formed on the second substrate layer and used for dispersing tension and stress generated when the bending area is bent. The manufacturingmethod of the flexible substrate comprises steps of providing the glass substrate, manufacturing the first substrate layer, manufacturing the second substrate layer and patterning the bending area. The flexible display panel comprises the flexible substrate, an array substrate, a light-emitting layer and a polaroid. The flexible substrate is advantaged in that tension and stress generated duringbending are dispersed through grooves, so the tension and stress generated during bending are reduced, the bending frequency of the second substrate layer can be increased, certain stiffness can be kept, and thereby the bending resistance and the impact resistance are enhanced.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible substrate, a flexible display panel and a method for manufacturing the flexible substrate. Background technique [0002] With the vigorous rise of the organic light-emitting diode (OLED) business, foldable products are booming, and among them, bending technology has become a bottleneck restricting the further development of products. As one of the emerging fields of flat panel display (FPD), flexible display technology is the general direction of the development of organic light emitting diode (OLED) in the future. Due to the advantages of the flexible display panel being thin, non-fragile, bendable and wearable, the flexible display panel has received more and more attention. [0003] The flexible display panel is thin and easy to bend, but its own stiffness (synonymous with "rigidity" and "hardness") is not enough. During the process of bending to flattening, the tension and str...
