Abstract

The invention provides a method for separating a display module group from a carrier substrate. The display module group and the carrier substrate are bonded together by an adhesive. The carrier substrate comprises a plurality of through holes. The separation method includes: adhesive glue disintegrants are injected into a plurality of through holes of the carrier substrate; and after decomposition of the adhesive glue by the adhesive glue disintegrants, the display module group and the carrier substrate are separated. According to the embodiment of the invention, the adhesive glue disintegrants are injected into the through holes and the adhesive glue disintegrants are in contact with the adhesive glue to produce chemical reaction, so that the activity of the adhesive glue is reduced andthus the display module group is easy to separate from the carrier substrate. Compared with the conventional physical separation method, the chemical separation method based on the chemical reaction between the adhesive glue disintegrants and the adhesive glue enables the display module group to be protected from being damaged by the physical separation force; and the difficulty of bonding betweenthe carrier substrate and the display module group is also reduced.

Description

technical field [0001] The invention relates to the technical field of substrate separation, in particular to a method for separating a display module from a carrier substrate and the carrier substrate. Background technique [0002] When the substrate of the flexible display screen is PI (polyimide) or PET (polyethylene terephthalate) substrate, the screen will lack certain stiffness. Therefore, the use of flexible glass substrates (ie, ultra-thin glass) with better stiffness and optical properties has become a trend in the future development of flexible display substrates. The use of flexible glass as a substrate also requires a glass carrier substrate as a support. At present, most flexible glass substrates and glass carrier substrates are physically separated. When the flexible glass substrate is separated from the carrier substrate, it is necessary to use external force to separate them, that is, to apply mechanical force to separate the carrier substrate from the flexi...
