Flexible display substrate and preparing method thereof

Abstract

The invention provides a flexible display substrate which can effectively release stress in metal wires and insulation layers and reduces the probability of breakage of the metal wires and the insulation layers in the bending processing of a flexible screen body. The invention further provides a preparing method of the flexible display substrate. By means of the preparing method of the flexible display substrate, aging of the flexible display substrate can be avoided, and the service life of the flexible display substrate can be prolonged. The flexible display substrate comprises a flexible substrate, the insulation layers and the metal layers are alternately arranged on the flexible substrate, the metal layers comprise metal wire sections which are arranged at intervals in the same or similar extending direction, contact holes formed in the parts, between the adjacent metal layers, of the insulation layers, the metal wire sections of the adjacent metal layers are alternately connected through metal in the contact holes, and continuous metal wires are formed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display substrate and a preparation method thereof. Background technique [0002] As a new generation of display products, flexible displays have attracted more and more attention because of their advantages such as ultra-light, ultra-thin, high-definition, fast response, bendable, and easy to carry. [0003] Flexible displays need to be rolled up or bent, or even bent frequently, so that the stress generated by the deformation will accumulate and superimpose on the metal wires and insulating layers in the display substrate, and the metal wires will break. After the second bending, the insulating layer will also face the risk of breaking, resulting in the failure of normal display and seriously affecting the service life of the flexible display. [0004] In order to solve the above technical problems, the industry mainly releases the stress by providing some holes on...

Problems solved by technology

Although this method can extend the use times of the metal wires and improve the reliability of the display, due to the limitation of materials, the cost is high, and the use of alternative materials will also cause obvious changes in the structure and preparation process of the flexible substrate, which cannot be achieved. Achieved through existing equipment and processes

[0006] In addition, the above-mentioned methods are only improvement measures taken against the breakage of metal wires. After adopting these measures, since the insulating layer is still continuous, the above-mentioned methods cannot effectively release the stress accumulated in the insulating layer to solve the problem that the insulating layer is easy to break. technical problem
