Problems solved by technology

In traditional flexible substrates, due to the poor stress of most inorganic layers, for example, silicon dioxide (SiO 2 ) material inorganic layer, when the bending range is large, the inorganic layers are easily squeezed to cause cracking, and the spurs generated by the cracking of the inorganic layer will also damage the organic layer, which will cause water vapor and oxygen to penetrate into the device, resulting in flexible displays.

Abstract

The invention discloses a flexible substrate. The flexible substrate comprises a first organic layer, a first inorganic layer, a second organic layer and a second inorganic layer. The patterned second organic layer is arranged on the first organic layer, the first inorganic layer comprises a plurality of first blocks arranged in a spacing manner, and each first block comprises a first middle portion and first edge portions arranged at two sides of the first middle portion. The second organic layer covers the first inorganic layer. The patterned second inorganic layer is disposed at one side, away from the first organic layer, of the second organic layer, the second inorganic layer comprises a plurality of second blocks arranged in a spacing manner, and each second block comprises a second middle portion and second edge portions arranged at two sides of the second middle portion. An extension direction of the second blocks is same with the extension direction of the first blocks, the second organic layer is partially embedded between the adjacent first block and second block, the first middle portions and the second middle portions are arranged in an alternating manner, and the first edge portions and the second edge portions are arranged in an overlapping manner. The flexible substrate is good in bending performance. The invention also discloses a flexible display device.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a flexible substrate and a flexible display using the flexible substrate. Background technique [0002] Flexible displays have the characteristics of being flexible, wearable, light, thin, low power consumption, and low radiation. They are considered to be the next generation of displays, and are now widely used in high-end cutting-edge products of various display terminals. [0003] A flexible display generally forms a thin film transistor (Thin Film Transistor, TFT) or other functional devices on a flexible substrate to achieve a display effect. Flexible substrates generally require good water vapor and oxygen barrier properties to ensure the stability of functional devices. [0004] The traditional flexible substrate structure usually adopts an alternate stacking arrangement of multi-layer organic layers and multi-layer inorganic layers. Both the organic layer...
