Description

Capacitive touch screen diaphragm

Technical field

The utility model relates to the screen protecting film of electronic equipment, is specifically related to capacitive touch screen diaphragm.

Background technology

Comprise the electronic equipment such as mobile phone, tablet device at present and be all equipped with capacitive touch screen, electronic equipment can by this capacitive touch screen display information on the one hand, and user can operate this electronic equipment at this capacitive touch screen with finger on the other hand.Adopt capacitive touch screen, electronic equipment can abandon most button, can increase the display area of electronic equipment thus.

The operation principle of capacitive touch screen is roughly, when user's finger touch is on capacitive touch screen, finger and capacitive touch screen form a coupling capacitance, due to capacitive touch screen being connected to high frequency electric, direct conductor for coupling capacitance high frequency electric, therefore the high frequency electric part on capacitive touch screen has flowed to human body, the electric current flowing to human body is flowed out by the electrode at four angles of capacitive touch screen, and be directly proportional from the electric current that the electrode at four angles flows out to the distance of finger to four angles, controller can be analyzed and draw the particular location of user's finger touch at capacitive touch screen thus.

But when user operates with finger on this capacitive touch screen, can be formed capacitive touch screen and block, thus the normal viewing of impact.It is less that this situation affects situation when user browses the operation such as webpage, viewing video; But user is when playing games, during the game of the fistfight type especially needing both hands to manipulate, the situation of impact is just very serious, and the impact for the little electronic equipment of screen is just more serious.

Utility model content

The technical problems to be solved in the utility model is user to blocking capacitive touch screen when the capacitive touch screen of electronic equipment operates.

For this reason, the utility model is by the following technical solutions:

Capacitive touch screen diaphragm, comprising:

The substrate layer of the insulation be equipped with on the capacitive touch screen of the electronic equipment of capacitive touch screen and in the frame region adjacent with described capacitive touch screens can be pasted on simultaneously,

Be located at the one side of described substrate layer, for described substrate layer being pasted on the adhered layer of the insulation of described capacitive touch screen or described frame region,

Be located at the another side of described substrate layer, when described substrate layer to be pasted on described capacitive touch screen and in described frame region time can be covered in the conductive layer of a part for described capacitive touch screen and a part for described frame region simultaneously.

The capacitive touch screen diaphragm that the utility model provides; user can touch the frame region beyond capacitive touch screen thus operate capacitive touch screen; thus avoid blocking capacitive touch screen, facilitate user to the use of electronic equipment being equipped with capacitive touch screen.

Detailed description of the invention

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

With reference to Fig. 1, Fig. 2, Fig. 3.

The capacitive touch screen diaphragm of the present embodiment, comprising:

The substrate layer 1 of the insulation be equipped with on the capacitive touch screen of the electronic equipment of capacitive touch screen and in the frame region adjacent with capacitive touch screens can be pasted on simultaneously,

Be located at the one side of substrate layer 1, for substrate layer 1 being pasted on the adhered layer 2 of the insulation of capacitive touch screen or frame region,

Be located at the another side of substrate layer 1, when substrate layer 1 to be pasted on capacitive touch screen and in frame region time can be covered in the conductive layer 3 of a part for capacitive touch screen and a part for frame region simultaneously.

Further, the another side of substrate layer 1 is provided with the conductive layer 3 of multiple not conducting mutually.

The operation principle of the capacitive touch screen diaphragm of the present embodiment is described below in conjunction with Fig. 3:

More existing electronic games need user operation upper and lower, left and right four direction, and it shows 4 virtual keys 5 as shown in Figure 3 on the capacitive touch screen of electronic equipment being equipped with capacitive touch screen.When this capacitive touch screen diaphragm is pasted on this capacitive touch screen; same conductive layer 3 covers a part for capacitive touch screen and a part for frame region simultaneously; wherein be covered in one of them virtual key 5 that the part correspondence of capacitive touch screen capacitive touch screen shows, the conductive layer 3 being arranged 4 mutual not conductings by reasonable layout can distinguish corresponding covering 4 virtual keys 5.

When user's finger touch conductive layer 3 be covered in the part of frame region time, conductive layer 3 is with the direct conducting of human body, point thus by conductive layer 3 can be corresponding with capacitive touch screen position formed coupling capacitance, thus trigger the virtual key 5 of correspondence position, realize the operation to this capacitive touch screen.

Therefore; the capacitive touch screen diaphragm that the present embodiment provides; user can touch frame region beyond capacitive touch screen thus to capacitive touch screen operation, thus avoids blocking capacitive touch screen, facilitates user to the use of electronic equipment being equipped with capacitive touch screen.

Further, substrate layer 1 or adhered layer 2 or conductive layer 3 are transparent or translucent.When conductive layer 3 is transparent, the position that user directly can not with the naked eye watch conductive layer 3, Fig. 1, Fig. 3 illustrate with dashed lines conductive layer 3.

The capacitive touch screen diaphragm that above the present embodiment provides, wherein the material of substrate layer 1 can be the polymer of such as PETG (being called for short PET) or polymethyl methacrylate (being called for short PMMA) and so on, or the glass of such as optical glass and so on;

The material of adhered layer 2 can silica gel;

ITO) material of conductive layer 3 can be that tin indium oxide (is called for short: conductive ink or other conducting polymers such as metal oxide, silver slurry or CNT such as.

In addition, because the voltage of the high frequency electric on capacitive touch screen is limited, for guaranteeing the sensitivity of touch operation, therefore, the thickness of the capacitive touch screen diaphragm of the present embodiment is 0.1mm ~ 0.33mm.

For coordinating the parts of such as receiver and so on electronic equipment, this capacitive touch screen diaphragm also can offer through hole 4.

More than for the utility model illustrates, be not limited to the utility model.
