Further technical scheme, described adhesive is binding agent, and the physical property of described binding agent is: adhesion strength is 0.8N/mm
2~ 1.5N/mm
2.
Further technical scheme, described TPLCD display screen is fixedly connected with through shading rubber belt with between the lower surface of described backlight module.
A touch screen structure preparation technology for smart mobile phone, its step is:
Backlight module and TPLCD display screen superimposed after, form lateral grooves, and the backlight module after superimposed and TPLCD display screen be positioned over below glue spraying equipment;
(2) according to touch screen, corresponding binding agent is selected to close-burning requirement;
(3) by the nozzle respective side groove of glue spraying equipment, and opposite side groove carries out filled type glue spraying;
(4) glue spraying simultaneously or after completing, process glue spraying surface, removal is overflowed part and ensured that glue permeates completely;
(5) to be bonded dose solidifies, and completes anabolic process.
Further technical scheme, described glue spraying equipment is untouchable high speed glue spraying equipment, and described nozzle can spray colloid from the top of described lateral grooves or side direction.
Further technical scheme, described lateral grooves by be positioned at described backlight module and TPLCD display screen superimposed after the groove combination that formed in arranged on left and right sides and top form, the width of described lateral grooves is 0.4mm ~ 0.6mm, and the degree of depth is 0.1mm ~ 0.3mm.
Further technical scheme, the physical property of described binding agent is: adhesion strength is 0.8N/mm
2~ 1.5N/mm
2.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention is by fixing through the adhesive adhesion of side at TPLCD display screen and backlight module, only use the connected mode of two-sided shading rubber belt as compared with the past, the bonding strength of TPLCD display screen and backlight module is improve while the screen proportion realizing mobile phone display screen is larger, also improve the qualification rate of product, and preparation technology is also more simple and convenient;
2. in the present invention, adhesive is made up of binding agent, and binding agent can according to the binding agent producing actual needs selection different size, and the scope of application is wider;
3. preparation technology of the present invention is simple and convenient, is easy to realize, and without the need to changing on a large scale existing structure, is applicable to promoting the use of.
