Problems solved by technology

[0002] The full-fit display screen has a small thickness and high light transmittance, which can reduce reflection and dust ingress. The full-fit process has been widely used in the bonding of display screens of different sizes and different application scenarios. In related technologies, large-size or During the full lamination process of super-sized display screens, there will be internal stress after the lamination panels are hot-pressed, resulting in warping and deformation of the display screens after lamination, which will affect the lamination yield of the display screens

Abstract

The invention discloses a large-size display screen laminating process which comprises the following steps: laminating an optical adhesive film between a first panel and a second panel, combining to form a to-be-cured body, carrying out vacuum hot pressing on the to-be-cured body, removing pressure, continuously heating the to-be-cured body, and curing the to-be-cured body. According to the large-size display screen laminating process provided by the embodiment of the invention, in the process of continuously heating the to-be-cured body, the first panel and the second panel release the stress and freely recover the stress, meanwhile, the optical adhesive film is gradually converted into a molten state, the optical cement freely flows between the first panel and the second panel and gradually fills the gap between the first panel and the second panel, so that the space between the two panels is filled with the optical cement, the attaching flatness of the first panel and the second panel is improved, and the attaching quality of the large-size display screen is improved.

Description

technical field [0001] The invention relates to the technical field of display screen bonding, in particular to a large-size display bonding process. Background technique [0002] The full-fit display screen has a small thickness and high light transmittance, which can reduce reflections and dust ingress. The full-fit process has been widely used in the bonding of display screens of different sizes and different application scenarios. In related technologies, large-size or During the full lamination process of super-sized display screens, there is internal stress after the lamination panels are hot-pressed, resulting in warping and deformation of the display screens after lamination, which affects the lamination yield of the display screens. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a bonding process for large-size display screens,...
