Abstract

The invention provides a soft-to-hard film sticking process and a film sticking product. The film sticking process includes the steps that step S1, vacuuming is respectively conducted on the upper andlower portions of a hard planar assembly of which film sticking needs to be conducted, a flexible protective film is placed on the upper portion of the hard planar assembly, and the vacuum degree atthe lower portion is greater than the vacuum degree at the upper portion; step S2, the flexible protective film is laminated on a sticking start end of the hard planar assembly by using a roller; stepS3, the vacuuming of the upper portion of the hard planar assembly is stopped, and the flexible protective film is rolled by using the roller until the film sticking of the hard planar assembly is completed. The deformation of the flexible protective film during the rolling process of the flexible protective film by using the roller is greatly reduced, and the tensile stress on the hard planar assembly is greatly reduced, so that the problem of warping of the hard planar assembly due to the tensile stress is effectively alleviated or even avoided, and the formation of pits and creases in thevacuum hole-adsorbed place after rolling by the roller and the protective film scratching due to the friction between the roller and the flexible protective film are avoided.

Description

technical field [0001] The invention relates to the field of 3D display equipment processing, in particular to a soft-to-hard film sticking process and film sticking products. Background technique [0002] In the 3D Cell manufacturing process, in order to prevent the cut and cleaned display panel from being polluted by the subsequent process, it is necessary to attach a protective film to the surface of the display panel (panel). [0003] Because the 3D Cell manufacturing process is: film == "Bonding ==" dispensing == "TEST (3D effect test), so the 3D display panel must not be warped, and there must be no air bubbles or creases after the protective film is attached, otherwise it will cause problems. Affects the detection of 3D effects. [0004] At present, the film-attaching process of screen detection in the panel industry generally adopts 6H ~ 9H anti-scratch protective film (hard protective film). Taking 9H anti-scratch protective film as an example, this type of protect...
