Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.

[0029] Referring to the method for preparing the transparent adhesive layer in the frame hole area of ​​the mobile phone panel in Fig. 1, the method comprises the following steps:

[0030] 1) see Figure 1a , first print the ink layer in the border area on the mobile phone panel 1, after the ink layer in the border area is cured, place the back of the mobile phone panel on the workbench, and ensure that the mobile phone panel is kept horizontal, and paste the protective film 2 on the back of the mobile phone panel 1 The position of the protective film 2 corresponding to the sensing hole is set as a hollow structure so that all the sensing holes are exposed (that is, it is set as a through-hole structure). In this embodiment, there are two sensing holes. P...

Abstract

The invention provides a preparing method for a transparent adhesive layer of a frame hole region of a mobile phone panel. The preparing method includes the following steps: a protection film is pasted on the back side of the mobile phone panel, optical adhesive dispensing is performed on induction holes on the back side of the mobile phone panel covered with the protection film, the optical adhesives are pressed flat by a pressure block, the adhesives are solidified, and the pressure block and the protection film are removed. The transparent adhesive layer with good smoothness and no bubblescan be prepared, and the subsequent light transmission effect of the induction holes after the film used for hiding the induction holes is pasted on the transparent adhesive layer is effectively guaranteed. In the process of pasting the protection film on the mobile phone panel, the upper surface of the protection film is provided with an auxiliary film, the total thickness of the film layer adsorbed by a film-absorbing plate can be increased, the generation of wrinkle after the film is adsorbed is avoided, the thickness and the stiffness of the film layer are increased, the thickness of subsequent dispensed adhesive is not influenced, the attaching difficulty is reduced, and the quality of the product is also risen.

Description

technical field [0001] The invention relates to a process for preparing an adhesive layer of a mobile phone panel of sewage treatment equipment, in particular to a method for preparing a transparent adhesive layer in a frame hole area of ​​a mobile phone panel. Background technique [0002] At present, the processing technology of mobile phone panels is becoming more and more complicated, and the types of protective films involved in the processing process are also increasing, and the requirements are getting higher and higher. The back of the existing mobile phone panels is generally provided with sensing holes and camera holes in the frame area ( Or other functional holes), because the frame area is to print ink, and the position of the frame area corresponding to the sensing hole and the camera hole cannot print ink because of the need for light transmission, therefore, the positions of the sensor hole and the camera hole are set as ink hollows The structure affects the a...
