Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The stripping device provided by the embodiment of the present invention can be used to strip the panel to be stripped. The panel to be peeled generally includes a substrate and a flexible panel grown on the substrate. figure 1 A structural schematic diagram of a peeling device provided for an embodiment of the present invention, such as figure 1 As shown, the peeling device includes: an upper cover 1 , a lower cover 2 , and a v...

Abstract

The invention provides a peeling device for peeling a flexible panel from a substrate surface of the panel to be peeled off, comprising: an upper cover, a lower cover, and a vacuum component; the connection side of the upper cover is movably connected with the connection side of the lower cover; When the upper cover and the lower cover are closed, the adsorption surface of the upper cover is opposite to the adsorption surface of the lower cover; the adsorption surface of the upper cover includes at least two first adsorption units, and the first adsorption units communicate with the vacuum components , which is used to adsorb the panel corner of the flexible panel through the vacuum component; the first adsorption unit is arranged in an area away from the connection side; The vacuum unit sucks the substrate. The influence of the intermediate effect on the peeling is avoided, and it is easier to initially peel the flexible panel from the substrate at the corner of the panel, thus reducing damage to the flexible panel due to peeling.

Description

technical field [0001] The invention relates to the field of flexible device manufacturing, in particular to a stripping device. Background technique [0002] Flexible panels are a research hotspot in the field of display, but their unique flexible features bring certain difficulties to the production process. [0003] Generally, the production process of the flexible panel includes: fabricating a flexible substrate on a rigid substrate; performing a device process (such as a thin film transistor array process) on the flexible substrate to obtain a flexible panel; and peeling off the flexible panel from the rigid substrate. In the lift-off process, laser lift-off (LLO) technology is generally used to reduce the adhesion between the flexible panel and the rigid substrate, and then the flexible panel is peeled off. [0004] However, it is easy to cause damage to the flexible panel during the peeling process, and how to reduce the damage to the flexible panel due to peeling is...
