Abstract
The utility model relates to the touch screen structure field, in particular to a capacitive touch screen. The capacitive touch screen comprises an indium tin oxide (ITO) glass, and a layer of high-temperature polyethylene terephthalate (PET) protective film is adhered to the back surface of the ITO glass. Due to the fact that the layer of high-temperature PET protective film is adhered to the back surface of the ITO glass, protective glue is not needed to spray on the back surface of the ITO glass, eventually a working procedure of conducting roast after spraying the protective glue is removed, and consequently not only are working procedures simplified, but also cost is lowered.
Description
Technical field
The utility model relates to the touch screen structure field, relates in particular a kind of capacitance type touch control screen.
Background technology
The capacitive touch screen of structure is no matter be G+F or G+F+F at present; because not being with the high temperature protection film in the ITO FILM supplied materials back side; in order to prevent back side scuffing and dirty; all be that the first operation is exactly to spray overleaf protection glue when feeding intake; to toast after having sprayed protection glue; production technology more complicated, and waste electric energy.
In view of this, the inventor has this case to produce for the defects further investigation of existing capacitance type touch screen structure then.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of cost low, the simple capacitance type touch control screen of production technology.
The purpose of this utility model is achieved by the following technical solution: capacitance type touch control screen comprises ito glass, it is characterized in that: be bonded with one deck high temperature PET diaphragm at the described ito glass back side.
The beneficial effect that the utility model is obtained: adopt behind the bonding one deck high temperature PET diaphragm of the ito glass back side; then need not at ito glass back spraying protection glue; finally saved and sprayed the operation that to toast behind the protection glue, not only simplified operation and reduced cost.
Description of drawings
Fig. 1 is schematic cross-section of the present utility model.
Embodiment
Referring to Fig. 1, capacitance type touch control screen of the present utility model comprises ito glass 1, is bonded with one deck high temperature PET diaphragm 2 at the described ito glass back side.Employing then need not finally to have saved and sprayed the operation that will toast behind the protection glue at ito glass back spraying protection glue behind the bonding one deck high temperature PET diaphragm of the ito glass back side, has not only simplified operation and has reduced cost.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present invention modifications and changes more of the present utility model.In addition, although used some specific terms in this instructions, these terms do not consist of any restriction to the utility model just for convenience of description.
