Problems solved by technology

[0005] However, the above method has the following defects: First, when the flexible substrate is peeled off, if the peeling strength of the adhesive is too high, the stress on the flexible substrate will be too large and the internal structure of the flexible substrate will be damaged.
Second, the cost of coating raw materials and stripping methods used for direct coating on hard substrates is relatively high

Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] figure 1 The structure of substrate structure 1 is shown. Such as figure 1 As shown, the substrate structure 1 includes a flexible motherboard 2 , a rigid motherboard 3 and an adhesive layer 4 . Wherein, the flexible motherboard 2 has a first active area 5 forming a flexible substrate and a first non-active area 6 located on the periphery of the first active area 5 . exist figure 1 In , the dotted line represents the boundary line between the first active area 5 and the first inactive area 6 . Correspondingly, the rigid motherboard 3 has a second active area 7 and a second inactive area 8, and the second active area 7 corresponds to the first active area 5, and the second inactive area 8 corresponds to the first inactive area 8. Similarly, the dotted line represents the boundary line between the second active area 7 and the second non-active area 8 . The adhes...

Abstract

The invention provides a method for manufacturing a flexible substrate and a substrate structure. The method comprises: 1) providing a rigid motherboard and a flexible motherboard, wherein a second active region of the rigid motherboard is corresponding to a first active region of the flexible motherboard, and a second non-active region of the rigid motherboard is corresponding to a first non-active region of the flexible motherboard; 2)disposing an adhesive layer on the rigid motherboard, wherein the adhesive layer comprises a strong adhesive layer and a weak adhesive layer, the strong adhesive layer is disposed on at least a part of the second non-active region, and the weak adhesive layer is disposed on the other part of the second non-active region and the second active region; 3) covering the adhesive layer with the flexible motherboard through adhering; and 4) cutting the flexible motherboard along an edge of the first active region. The method enables the flexible motherboard to be subjected to a smaller stress during peeling, thus protecting the internal part of the flexible substrate from being damaged.

Description

technical field [0001] The present invention relates to the field of flexible display technology, in particular to a method for manufacturing a flexible substrate and a substrate structure. Background technique [0002] Flexible display refers to a type of display device or display technology that uses flexible substrates and can be manufactured into ultra-thin, ultra-large, and bendable display devices. Flexible display has incomparable advantages over flat panel display, and is a very promising display technology. Through years of scientific research and development, flexible display technology has developed rapidly. [0003] At present, flexible substrates are characterized by thinness, lightness, and flexibility. Therefore, in the production process, the flexible substrate is generally attached to the hard substrate, and the flexible substrate is formed after shaping, and then peeled off after the device manufacturing process is completed. [0004] In the prior art, t...
