The technical scheme adopted by the invention is as follows:
a curved surface 0 laminating structure suitable for touch products comprises a TPM module and an LCM glue frame, wherein the LCM glue frame is provided with a first step surface and a second step surface, the second step surface is positioned above the first step surface, the TPM module comprises a glass cover plate CG and a Sensor film which are arranged from top to bottom, the thickness of the glass cover plate CG is 1.1 +/-0.1 mm, and the lower surfaces of two ends of the Sensor film are laminated on the second step surface through foam tapes; OC is arranged on the bottom surface of a Sensor film of the TPM module, and the lower surfaces of two ends of the OC are arranged on the first step surface through a soft TAPE TAPE; the thickness of the foam adhesive tape meets the condition that the height distance from the bottom surfaces at two ends of the Sensor film to the OC is not more than 1.0mm, and the height distance from the bottom surface in the middle of the Sensor film to the OC is not less than 0.6 mm.
Further, the thickness of the glass cover plate CG is 1.1.
Furthermore, the LCM rubber frame is an LCM rubber frame with a double-step-surface structure and integrated with a first step surface and a second step surface.
Further, the LCM rubber frame comprises a single-step LCM rubber frame and a second step face outer frame, the second step face outer frame is fixed on the outer side of the single-step LCM rubber frame through a VBH or a screw and forms a combined type double-step face structure with the first step face.
Furthermore, an AR film is attached to the bottom layer of the TPM module, so that the reflection characteristic is improved to improve the penetration rate.
A curved surface touch terminal adopts a curved surface 0 laminating structure suitable for touch products.
By adopting the technical scheme, the thickness of the glass cover plate CG is selected to be 1.1 +/-0.1 mm, so that the problems that the glass stress is too large due to too thick glass cover plate CG, the adhesive is not firmly stuck and is warped and even the glass is broken due to bending stress are avoided; or the glass cover plate CG is too thin to cause too large pressing deformation, Mura occurs when the TPM is contacted with the CELL surface during touch control, and thus, the visual and touch experience effects are poor because only the gap between the TPM and the CELL can be enlarged; simultaneously based on first step face and the second step face structure that LCM glued frame had, set up soft TAPE TAPE and bubble cotton TAPE, with the crooked laminating of TPM on LCM glued frame step face, the laminating sticky TAPE is with waterproof bubble cotton TAPE, except waterproof, bubble cotton TAPE can also play the cushioning effect except fixed, avoids vibrating or falling the LCM glued frame and warp and lead to glass to break in the transportation. The invention adopts a gradual change Gap scheme, and the Gap between the TPM and the CELL is kept between 0.6 and 1mm by controlling the thicknesses of the soft TAPE TAPE and the foam adhesive TAPE, the Gap in the middle is small, and the Gap on the two sides is large. The height of the section of the frame platform is gradually reduced from the middle to two sides (the middle is kept at 0.6mm, and the GAP between two sides is not less than 0.6mm and not more than 1 mm), so that the problem that the touch experience effect of GAP not less than 1mm is poor or the pressing of GAP not less than 0.6mm can touch the surface of CELL to cause Mura is solved. Compared with full bonding, the bonding of the invention 0 has slightly larger penetration effect, but has no great difference in use experience, if the penetration is improved to be consistent with the full bonding effect by a certain requirement, optical bonding can be adopted, namely an AR film is additionally bonded on the bottom layer of the TPM, so that the reflection characteristic is improved and the penetration is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
As shown in one of fig. 1 to 5, the present invention discloses a curved surface 0 attaching structure suitable for a touch product, which includes a TPM module 1 and an LCM frame 2, wherein the LCM frame 2 has a first step surface 3 and a second step surface 4, the second step surface 4 is located above the first step surface 3, the TPM module 1 includes a glass cover plate CG 5 and a Sensor film 6 arranged from top to bottom, the thickness of the glass cover plate CG 5 is 1.1 ± 0.1mm, and the lower surfaces of two ends of the Sensor film 6 are attached to the second step surface 4 through a foam adhesive tape 7; OC 8 is arranged on the bottom surface of the Sensor film 6 of the TPM module 1, and the lower surfaces of two ends of the OC 8 are arranged on the first step surface 3 through a soft belt TAPE 9; the Gap between the TPM module 1 and the CELL is kept between 0.6mm and 1mm, the touch experience effect is not good when the Gap is larger than or equal to 1mm, and Mura appears when the Gap is pressed to the surface of the CELL when the Gap is smaller than or equal to 0.6 mm.
Further, the thickness of the glass cover plate CG 5 is 1.1. If too thick glass stress is too big, the rubberizing is not firm to stick up and even glass appears because bending stress breaks, and glass is thin to press and is out of shape too big, and Mura can appear to TPM contact CELL face during the touch-control, can only enlarge the clearance between TPM and CELL like this and lead to vision and touch-control experience effect to worsen.
Further, as shown in fig. 3, the LCM rubber frame 2 is a double-step-surface LCM rubber frame 2 in which a first step surface 3 and a second step surface 4 are integrated.
Further, as shown in fig. 4, the LCM rubber frame 2 includes a single-step LCM rubber frame 20 and a second step outer frame 21, and the second step outer frame 21 is fixed to the outer side of the single-step LCM rubber frame 20 through VBH or screws and forms a combined double-step structure with the first step.
Further, an AR film (not shown) is attached to the bottom layer of the TPM module 1 to improve the reflection characteristic and enhance the transmittance.
By adopting the technical scheme, the thickness of the glass cover plate CG 5 is selected to be 1.1 +/-0.1 mm, so that the problems that the glass stress is too large due to too thick glass cover plate CG 5, the adhesive is not firmly warped, and even the glass is broken due to bending stress are avoided; or the glass cover plate CG 5 is too thin to cause overlarge pressing deformation, Mura appears when the TPM is contacted with the CELL surface during touch control, so that the visual and touch experience effects are poor due to the fact that only the gap between the TPM and the CELL can be enlarged; simultaneously based on first step face 3 and the 4 structures of second step face that LCM glued frame 2 had, set up soft TAPE TAPE 9 and bubble cotton TAPE 7, with the crooked laminating of TPM on LCM glued frame 2 on the step face, the laminating sticky TAPE is with waterproof bubble cotton TAPE 7, except waterproof, bubble cotton TAPE 7 except fixed can also play the cushioning effect, avoids vibrating or falling LCM glued frame 2 and warp and lead to glass to break in the transportation. As shown in fig. 5, when the TPM is in a bent state in the prior art, a uniform Gap is maintained between the TPM and the CELL, so that the left and right stresses are greatly different from the middle, and Mura is likely to occur when left and right sides are pressed. In order to solve the problem, the invention adopts a gradual change Gap scheme, and the Gap between the TPM and the CELL is kept between 0.6 and 1mm by controlling the thicknesses of the soft TAPE TAPE 9 and the foam adhesive TAPE 7, wherein the Gap in the middle is small, and the gaps on the two sides are large. The height of the section of the frame platform is gradually reduced from the middle to two sides (the middle is kept at 0.6mm, and the GAP between two sides is not less than 0.6mm and not more than 1 mm), so that the problem that the touch experience effect of GAP not less than 1mm is poor or the pressing of GAP not less than 0.6mm can touch the surface of CELL to cause Mura is solved. Compared with full bonding, the bonding of the invention 0 has slightly larger penetration effect, but has no great difference in use experience, if the penetration is improved to be consistent with the full bonding effect by a certain requirement, optical bonding can be adopted, namely an AR film is additionally bonded on the bottom layer of the TPM, so that the reflection characteristic is improved and the penetration is improved.
