Abstract

The invention provides a laminated flexible substrate and a production method. The production method comprises the following steps of coating a first organic layer on a substrate, and forming a plurality of first grooves on the first organic layer; depositing a first inorganic layer on the first organic layer, wherein the maximum thickness of the first inorganic layer is smaller than the minimum depth of the first grooves; depositing a second organic layer on the first inorganic layer, and forming a plurality of second grooves on the second organic layer; depositing a second inorganic layer on the second organic layer, wherein the maximum thickness of the second inorganic layer is smaller than the minimum depth of the second grooves; coating a flat bed on the second inorganic layer; and stripping the substrate from the first organic layer. According to the laminated flexible substrate and the production method which are provided by the invention, an adhesive force between the organic layers is increased, the possibility that a film surface falls off in the subsequent product process is reduced, and the probability that stresses are accumulated when the laminated flexible substrate is bent is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a laminated flexible substrate and a manufacturing method. Background technique [0002] In flexible display panels, a stacked flexible substrate is usually used, that is, using "organic-inorganic-organic-inorganic" multi-layer overlapping films as a flexible substrate to improve the ability of the display substrate to block water and oxygen. In the current laminated flexible substrates, there may be: ① damage to the film surface caused by stress accumulation of inorganic thin films; ② mis-delamination of the film surface caused by insufficient adhesion of the organic-inorganic thin film interface. [0003] Therefore, there are defects in the prior art, and improvement is badly needed. Contents of the invention [0004] The object of the present invention is to provide a laminated flexible substrate and a manufacturing method to solve the problem of film surface damage caused by stress acc...
