Abstract

The invention discloses a peeling device of a flexible substrate and a peeling method of the flexible substrate. The peeling device and the peeling method are used for solving the problems of wrapped local part of the flexible substrate and bad product quality when the flexible substrate is peeled off by a laser peeling technology. The peeling device includes a base platform, a pressing plate arranged at the upper part of the base platform and a laser generator arranged at the lower part of the base platform; the pressing plate is provided with a negative pressure channel, one face towards the base platform is provided with a suction covering opening connected with the negative pressure channel; the base table is used for bearing a lining base plate formed with a flexible substrate to be peeled; the flexible substrate to be peeled is provided with an exhaust passage formed by laser cutting; a laser generator is used for emitting laser and heating the flexible substrate to be peeled, so that one contact face between the flexible substrate to be peeled and the lining substrate is decomposed and then peeled; the pressing covering plate is used for pressing and covering the flexible substrate to be peeled and absorbing gas by the negative pressure channel through the suction covering opening when the flexible substrate to be peeled is decomposed.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a stripping device and a stripping method for a flexible substrate. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) technology has developed rapidly in the past ten years, and great progress has been made in terms of screen size and display quality. With the development of flexible display technology, it is closer to the flexibility of traditional display modes. Display products will soon enter the homes of ordinary people. Due to the unique bendable characteristics of flexible display itself, it will have many special user experiences. [0003] In the process of preparing flexible devices, how to separate the flexible substrate from the carrier substrate is a key technology for preparing flexible devices in the field of flexible display technology. In the prior art, a mechanical lift-off or a laser lift-off technique is used, and the las...
