Flexible substrate, fabrication method thereof and display device

Abstract

The invention provides a flexible substrate, a fabrication method thereof and a display device, and relates to the technical field of display. By the flexible substrate, the fabrication method thereofand the display device, the problem that the flexible substrate is easy to damage and generate crack is solved. The flexible substrate comprises a first flexible substrate, wherein the first flexiblesubstrate comprises a first flexible film layer and a first spacing layer, the first flexible film layer comprises a flexible film layer body and a plurality of bulges, the plurality of bulges are arranged on a surface of the flexible film layer body, the first spacing layer is arranged on the first flexible film layer and comprises a plurality of first island patterns, each bulge is corresponding to each first island pattern, the projection of a gap between adjacent bulges and the projection of a gap between adjacent first island patterns on the flexible film layer body are provided with a first overlap region, a first groove defined by the bulges and the first island pattern is filled with an organic material under the condition that the first island patters cover the plurality of bulges, the height of the organic material is smaller than the height of the first groove, and the gap between adjacent first island patterns is filled with the organic material under the condition that the first island patterns are arranged at one side, far away from the bulges, of the flexible film layer body.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible substrate, a preparation method thereof, and a display device. Background technique [0002] With the development of flexible technology, flexible devices are gradually transitioning from bendable, foldable, and stretchable to meet users' requirements for more deformation of flexible devices. [0003] like figure 1 As shown, the existing flexible substrate generally includes a double-layer flexible substrate, and each layer of flexible substrate includes a flexible film layer and a barrier layer disposed on the flexible film layer. [0004] However, due to the presence of a thicker inorganic film layer (including the spacer layer) on the flexible substrate substrate, when bending or stretching with a smaller radius, the probability of the inorganic film layer being damaged or cracked is greatly increased; especially When the flexible substrate is elastically flexibl...

AI Technical Summary

Problems solved by technology

[0004] However, due to the presence of a thicker inorganic film layer (including the spacer layer) on the flexible substrate substrate, when bending or stretching with a smaller radius, the probability of the inorganic film layer being damaged or cracked is greatly increased; especially When the flexible substrate is elastically flexible, due to the severe local deformation, the inorganic film layer is more likely to cause micro-damages through collisions, separations, etc., and the micro-damages gradually expand into larger cracks and expand along the flexible substrate, resulting in Damage to the flexible substrate substrate, when the flexible substrate substrate is applied to a display device, the reliability of the display device is deteriorated
