Embodiment 1

[0064] Using a PET layer with silicone pressure-sensitive adhesive as a flexible protective film, the hardness of the flexible protective film is..., placing 10 3D display panel components on the base, and setting the flexible protective film above the 3D display panel components , the upper and lower parts of the hard plane component to be filmed are evacuated respectively, and the vacuum degree of the lower part is controlled to be -50KPa, and the upper part is -20KPa; the flexible protective film is pressed onto the 3D display panel component by using rollers Start end: Stop vacuuming above the hard plane component and use rollers to roll the flexible protective film until the film sticking of the hard plane component is completed. The rolling pressure is controlled to 25N, and the moving speed of the roller is 80mm / s. Then use a plug gauge on the marble platform to measure the GAP value from the lower surface of the 3D display panel assembly to the marble platform (the test...

Embodiment 2

[0078] A PET layer provided with a silicone pressure-sensitive adhesive is used as a flexible protective film, the hardness of the flexible protective film is 4H, 10 3D display panel components are placed on the abutment, and the flexible protective film is arranged above the 3D display panel component , the top and bottom of the hard plane component to be filmed are vacuumed respectively, and the vacuum degree of the lower part is controlled to be -20KPa, and the vacuum degree of the upper part is -0.01KPa; the flexible protective film is pressed onto the 3D display panel component by using rollers. Close the starting end; stop vacuuming the top of the hard plane component and use the roller to roll the flexible protective film until the film of the hard plane component is completed, control the rolling pressure to 25N, and the moving speed of the roller to 80mm / s . Then measure the GAP value from the lower surface of the 3D display panel assembly to the marble platform with ...

Embodiment 3

[0082] A PET layer provided with a silicone pressure-sensitive adhesive is used as a flexible protective film, the hardness of the flexible protective film is 4H, 10 3D display panel components are placed on the abutment, and the flexible protective film is arranged above the 3D display panel component , the top and bottom of the hard plane component to be filmed are vacuumed separately, and the vacuum degree of the lower part is controlled to be -50KPa, and the vacuum degree of the upper part is -30KPa; the flexible protective film is pressed on the 3D display panel component by rollers Start end: stop vacuuming above the hard plane component and use rollers to roll the flexible protective film until the film sticking of the hard plane component is completed. Control the rolling pressure to 25N and the speed of the roller to 80mm / s. Then measure the GAP value from the lower surface of the 3D display panel assembly to the marble platform with a plug gauge on the marble platform...

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...
