specific Embodiment approach 1

[0028] Specific embodiment 1: This embodiment is a full lamination method of GF touch screen, which is characterized in that the method is specifically completed according to the following steps:

[0029] 1. Substrate imposition:

[0030] Place the single piece of tempered glass substrate in turn on the large-scale special positioning jig;

[0031] Two, silk screen curing glue:

[0032] Screen-print the liquid optical glue for full lamination onto the surface of the single-piece tempered glass substrate by printing to obtain a single-piece tempered glass with silk-screened and cured glue;

[0033] 3. Laminating machine loading:

[0034] Vacuum absorb the single piece of conductive glass on the lower loading platform of the laminating machine; vacuum absorb the single piece of tempered glass with silk-screened cured glue on the upper loading platform of the laminating machine;

[0035] Fourth, counterpoint:

[0036] Monitor and adjust the lower chamber of the laminating mac...

specific Embodiment approach 2

[0049] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the liquid optical adhesive for full lamination described in step 2 consists of 10 parts to 60 parts of modified liquid isoprene rubber prepolymer by weight percentage , 10~60 parts of modified epoxy resin, 2.5~15 parts of reactive diluent, 15~50 parts of hybrid photoinitiator, 1~20 parts of auxiliary agent and 2~10 parts of sol polymer to make. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

Abstract

The invention provides a full lamination method of a GF (glass film) touch screen and relates to a full lamination process of a capacitive touch screen. The invention aims at solving the problems that no effectively full lamination process exists when the GF touch screen is made currently, the yield and the efficiency are low, and optical properties such as the refractive index cannot meet requirements in the dual curing of the conventional liquid optical clear adhesive. The method comprises the following steps: 1, imposition of base plates; 2, silk-screen of a curing adhesive; 3, feeding of a laminating machine; 4, alignment; 5, vacuumizing; 6, laminating, and 7, curing, so that the fully laminated GF touch screen is obtained after the curing adhesive is cured, that is, the full lamination method of the GF touch screen is completed. The full lamination method of the GF touch screen can be obtained.

Description

technical field [0001] The invention relates to a full bonding process of a capacitive touch screen. Background technique [0002] The touch screen is a simple, convenient and natural human-computer interaction device, which has been widely used in various places. There are many types of touch screens, which are mainly divided into resistive type, capacitive type, infrared type and surface acoustic wave type according to the principle. The capacitive touch screen uses the induced current generated by the capacitance change generated by the electrostatic combination between the electrode on the glass substrate and the human body to detect the coordinates of its touched position. The induction principle uses a voltage to act on the four corners of the screen sensing area and forms a fixed electric field. When the finger touches the screen, the electric field can cause a current. With the help of the controller, the contact can be calculated according to the ratio of the four ...
