specific Embodiment approach 1

[0029] Specific implementation mode one: the full bonding method of the GG touch screen in this implementation mode includes the following steps:

[0030] 1. Place the GG touch screen on the platform and fix it, attach the OCA optical glue to the GG touch screen, heat the GG touch screen with the OCA optical glue attached, stick the protective glass and the GG touch screen together, and then put it in Vacuum packaging machine for vacuum lamination;

[0031] 2. Then paste OCA optical glue on the side of the GG touch screen that is not attached to the protective glass;

[0032] 3. GG touch screen and display module rely on fixture positioning;

[0033] 4. Vacuumize the GG touch screen and the display module, and after the alignment is completed, put it into the vacuum packaging machine for vacuuming and full lamination;

[0034] 5. GG touch screen and display module break vacuum and heat and pressurize to remove bubbles.

specific Embodiment approach 2

[0035] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the preparation method of the GG touch screen is as follows:

[0036] Clean the large piece of cover glass, cut, edge and groove the large piece of cover glass to obtain the white piece of cover glass that meets the shape requirements;

[0037] Screen-print the required ink pattern on the inner surface of the cover glass white sheet to obtain the cover glass;

[0038] Clean the large piece of functional glass, make a circuit pattern on one side of the large piece of functional glass, cut the large piece of functional glass, and obtain a glass functional piece that is compatible with the shape of the white cover glass;

[0039] Bind the flexible circuit board on the glass functional sheet to obtain the glass functional sheet binding module;

[0040] Bond the ink side of the cover glass with the line pattern side of the glass functional sheet binding module through OCR liquid ...

specific Embodiment approach 3

[0041] Embodiment 3: This embodiment is different from Embodiment 2 in that: the thickness of the large cover glass is 0.45mm~0.55mm. Others are the same as in the second embodiment.

Abstract

The invention relates to the technical field of touch screens, in particular to a full-gluing method of a GG touch screen, and solves the problems of low yield, relatively high cost, difficult control over adhesion precision, OCA glue excess or OCA offset in the conventional lamination method of the touch screen. The full-gluing method comprises the following steps: 1, gluing OCA optical glue onto the GG touch screen, heating, gluing protective glass and the GG touch screen together, and putting into a vacuumizing packaging machine for vacuumizing full gluing; 2, then gluing OCA optical glue onto one side, without the protective glass, of the GG touch screen; 3, positioning the GG touch screen and a display module by a jig; 4, vacuumizing the GG touch screen and the display module, aligning, and then putting into the vacuumizing packaging machine for vacuumizing full gluing; 5, performing vacuum breaking on the GG touch screen and the display module, heating, pressurizing and removing bubbles. The full-gluing method is used for gluing the GG touch screen.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a full bonding method of GG touch screens. Background technique [0002] The touch screen is an input device that significantly improves the man-machine interface, and has the advantages of intuition, simplicity and speed. Touch screens have been widely used in many electronic products, such as mobile phones, PADs, multimedia, and public information inquiry systems. [0003] GG touch screen is composed of sensor glass and tempered glass cover. GG touch screen is widely used due to its advantages of hard wear resistance, corrosion resistance, high light transmittance, and smooth handling. [0004] Full lamination means that the panel and the touch screen are completely pasted together in a seamless manner with water glue or optical glue. Compared with frame stickers, it can provide better display effect. The full-fit technology eliminates the air between the screens, whic...
