Detailed Description
For the purposes, technical solutions and advantages of the embodiments of the present application, 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 invention discloses a curved surface 0 attaching structure suitable for a touch product, which comprises a TPM module 1 and an LCM adhesive frame 2, wherein the LCM adhesive frame 2 is provided with a first step surface 3 and a second step surface 4, the second step surface 4 is positioned above the first step surface 3, the TPM module 1 comprises a glass cover plate CG 5 and a Sensor film 6 which are arranged from top to bottom, the thickness of the glass cover plate CG 5 is 1.1+/-0.1 mm, and the lower surfaces of two ends of the Sensor film 6 are attached to the second step surface 4 through foam tapes 7; OC 8 is arranged on the bottom surface of the Sensor film 6 of the TPM module 1, and the lower surfaces of the two ends of the OC 8 are arranged on the first step surface 3 through a soft belt TAPE 9; gap between the TPM module 1 and the CELL is kept between 0.6 and 1mm, touch experience effect of more than or equal to 1mm is poor, and Mura appears when the CELL surface is touched by pressing less than or equal to 0.6mm.
Further, the glass cover CG 5 has a thickness of 1.1. If too thick glass stress is too big, rubberizing is not firm to warp and even glass appears because bending stress breaks, and glass is thin to press the deformation too big, and the TPM can appear Mura to the CELL face in touch-control, can only increase the clearance between TPM and the CELL like this and lead to vision and touch-control experience effect to become poor.
Further, as shown in fig. 3, the LCM rubber frame 2 is an LCM rubber frame 2 with a double-step-surface structure in which a first step surface 3 and a second step surface 4 are integrated.
Further, as shown in fig. 4, the LCM glue frame 2 includes a LCM glue frame 20 with a single step surface and a second step surface outer frame 21, where the second step surface outer frame 21 is fixed on the outer side of the LCM glue frame 20 with a single step surface by VBH or screws and forms a combined double step surface structure with the first step surface.
Further, an AR film (not shown) is attached to the bottom layer of the TPM module 1, so as to improve the reflection characteristic and 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 situation that the glass is excessively stressed due to the fact that the glass cover plate CG 5 is too thick, the rubberizing is not firmly warped and even the glass is broken due to bending stress is avoided; or the glass cover plate CG 5 is too thin to cause excessive pressing deformation, mura can occur when the TPM contacts with the CELL surface during touch control, so that the gap between the TPM and the CELL can only be enlarged to cause poor visual and touch control experience effects; meanwhile, based on the structures of the first step surface 3 and the second step surface 4 of the LCM rubber frame 2, the soft belt TAPE 9 and the foam rubber belt 7 are arranged, the TPM is bent and attached to the upper step surface of the LCM rubber frame 2, the waterproof foam rubber belt 7 for attaching the rubber belt is used, besides being waterproof, the foam rubber belt 7 can play a buffering role except fixing, and glass breakage caused by vibration or falling of the LCM rubber frame 2 deformation in the transportation process is avoided. As shown in fig. 5, in the prior art, when the TPM is in a curved state and the stress between the TPM and the CELL is uniform, the stress will be greatly different from the stress in the middle, and Mura will easily occur when the TPM is pressed on both sides. In order to solve the problem, the invention adopts a gradual change Gap scheme, and the thickness of the soft belt TAPE 9 and the foam adhesive TAPE 7 is controlled to ensure that the Gap between the TPM and the CELL is kept between 0.6 and 1mm, and the Gap is small in the middle and large on two sides. The height of the section of the rubber frame table is adjusted by decreasing from the middle to two sides (the middle is kept at 0.6mm, the GAP is not smaller than 1mm at the two sides), and the problems that the touch experience effect of GAP is not smaller than 1mm or the contact of the GAP with the surface of the CELL is not smaller than 0.6mm are avoided. Compared with full lamination, the lamination of the invention 0 has a slightly larger penetration rate effect, but has no great difference in use experience, if the penetration rate is improved to be consistent with the full lamination effect by certain requirements, an optical bonding can be adopted, namely an AR film is added on the bottom layer of the TPM, and the reflection characteristic is improved to improve the penetration rate.
