In the reflection of each interlayer, the fuzzy of image character is also resulted in.
The content of the invention
The purpose of this utility model is to provide a kind of touch-screen of monofilm multi-point touch, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the utility model provides following technical scheme：A kind of touch-screen of monofilm multi-point touch,
Including electrode, screen body, electrode unit, driving electrodes, toughened glass layer and base plate, fixing groove is provided with the screen, and is shielded
Four electrodes are installed with it, the electrode is connected with transparent conductive film, and poly- terephthaldehyde is scribbled on transparent conductive film
Sour glycol ester, the transparent conductive film is fixed in toughened glass layer by adhesion, and the lower section of toughened glass layer is arranged
There is conductive layer, multiple electrodes unit is provided with the conductive layer, and electrode unit forms array, sets below the conductive layer
Non-conductive glass screen is equipped with, and screen layer is arranged on the top of base plate, and receiving electrode, the driving electricity are provided with the base plate
Pole is connected by wire with electrode, and drives buffer to be arranged on the right side of driving electrodes.
Preferably, non-conductive glass screen is installed above the screen layer.
Preferably, connected by wire between the driving electrodes and driving buffer.
Preferably, three correction points are provided with the electrode unit.
Compared with prior art, the beneficial effects of the utility model are：The uppermost coating of the equipment is poly- to benzene two
Formic acid glycol ester；PET can make touch-screen accomplish thinner, more cheap than existing plastic and glass material, make screen body more
Plus it is frivolous, product cost is reduced, the equipment is provided with multiple electrodes unit, it is possible to achieve multi-point touch, and the side of touch-screen four is equal
Long and narrow electrode is plated, conductive a low-voltage AC electric field is formed in vivo, finger can form one and couple with conductor interlayer
Electric capacity, the electric current that four side electrodes send can flow to contact, and electric current power is inversely proportional to the distance of finger to electrode, positioned at touch
Receiving electrode after screen will calculating current ratio and power, accurately calculate the position of touch point, can be effectively prevented outer
Touch-screen is impacted in environmental factor, even if screen speckles with filth, dust or oil stain, capacitive touch screen still can be accurate
Calculate touch location, not only can multi-point touch, and it is more accurate to shield sensing of the body to finger.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, a kind of embodiment that the utility model is provided：A kind of touch-screen of monofilm multi-point touch,
Including electrode 1, screen body 5, electrode unit 6, driving electrodes 7, toughened glass layer 9 and base plate 16, fixing groove 2 is provided with screen body 5,
And shield body 5 on four electrodes 1 are installed, electrode 1 is connected with transparent conductive film 11, and scribble on transparent conductive film 11 it is poly- right
PET 10, transparent conductive film 11 is fixed in toughened glass layer 9 by adhesion, and toughened glass layer 9
Lower section is provided with conductive layer 12, conductive layer 12 and is provided with multiple electrodes unit 6, and electrode unit 6 forms array, conductive layer 12
Lower section be provided with non-conductive glass screen 13, and screen layer 14 is arranged in the top of base plate 16, base plate 16 and is provided with reception electricity
