Glass screen, the inner surface and interlayer of glass screen are respectively coated with one layer of ITO, and outermost layer is a thin layer silica protective layer for glass, interlayer ITO
Coating draws four electrodes as working face on four angles, internal layer ITO is shielded layer to guarantee good working environment.Work as hand
Refer to that, due to human body electric field, user and touch screen surface are formed with a coupled capacitor, for high-frequency electrical when touching on the metal layer
For stream, capacitor is direct conductor, and then finger siphons away the electric current of a very little from contact point.This electric current is respectively from touch screen
Quadrangle on electrode in flow out, and the electric current for flowing through this four electrodes is directly proportional at a distance from finger to quadrangle, controller
By accurately calculating to this four current ratios, the position of touch point is obtained.The position of touch point is exactly touch panel sensor
The core of structure design.
Touch panel sensor structure is divided into single side bridging type, two-sided square-shaped, caterpillar formula, oblique trigonometric expression etc..Compare into
Ripe technology is " G+F+F " structural formula touch screen, i.e. acierage glass+ito thin film+ito thin film structure touch screen.It is existing
There is the major defect of design to be, the ito thin film of such touch screen has used two panels, i.e. silk-screen is acidproof (ITO pattern), silk-screen
Silver paste has respectively used two procedures, and last two panels ito thin film inductive layer fitting has respectively used OCA with FOG, led to increased costs,
Gross profit reduces.And the visible light transmittance of ito thin film is not as good as ito glass.

Detailed description of the invention
A specific embodiment of the invention is furtherd elucidate with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the two-sided shadow touch panel sensor that disappears.
Specific embodiment
In conjunction with Fig. 1, the present invention is further detailed.
A kind of two-sided shadow touch panel sensor that disappears includes ultra thin glass substrates 1(sensor glass), disappear shadow layer, top
ITO inductive layer 4(top ITO sensor), bottom ITO inductive layer 5(bottom ITO driver), glass cover-plate 7(cover
Lens), about 1 ultra thin glass substrates are two-sided is coated with the shadow layer that disappears, and top ITO inductive layer 4 is plated in above ultra thin glass substrates 1 shadow that disappears
Layer surface, bottom ITO inductive layer 5 are plated in below ultra thin glass substrates 1 the shadow layer surface that disappears, ultra thin glass substrates 1 and glass cover-plate 7
It is bonded by OCA6.
As shown in Figure 1, top ITO inductive layer 4 and bottom ITO inductive layer 5 are integrated into the upper of a piece of ultra thin glass substrates 1
Surface and lower surface.Ultra thin glass substrates 1 are the main body for carrying ITO inductive layer, are incuded in ultra thin glass substrates 1 and two ITO
One layer of light refractive index matching layer is suffered between layer to disappear shadow layer, finally by the ultra thin glass substrates 1 of integrated ITO inductive layer and
Glass cover-plate 7 is bonded by OCA6.This structure design saves one to substitute two panels ITO film with ultra thin glass substrates 1
The cost of piece ito thin film.
Ultra thin glass substrates 1 with a thickness of 0.2mm.
Glass substrate can sputter ITO with high temperature, and ITO layer is crystalline state, compared with ito thin film, does not need aging process, save
About process time.
The shadow layer that disappears includes bilayer, respectively niobium pentaoxide layer 2 and silicon dioxide layer 3.
Disappear shadow layer and top ITO inductive layer 4 and bottom ITO inductive layer 5 is by two-sided one-pass molding sputter coating shape
At.
Successively the niobium pentaoxide layer 2 of shadow layer that disappears, the silicon dioxide layer 3 for the shadow layer that disappears, ITO sense are plated in two-sided one-pass molding sputtering
Layer (the two-sided one-pass molding sputtering plating simultaneously of top ITO inductive layer 4 and bottom ITO inductive layer 5) is answered, it can be with by increasing the shadow layer that disappears
Low resistance ITO bring etched mark is reduced, while also increasing the visible light transmittance of whole ito glass sensor.
It, be by Huang after top ITO inductive layer 4 and bottom ITO inductive layer 5 are formed by two-sided one-pass molding sputter coating
Light technology processing.
Keep ITO inductive layer graphical by yellow light process.
Sensor structure and frame cabling are completed with the ITO of low resistance, instead of silk-screen silver paste technique twice, is also saved
Silver paste cost.
4 upper surface of top ITO inductive layer of ultra thin glass substrates 1 is bonded with the lower surface of glass cover-plate 7 by OCA6.
The production technology of the two-sided shadow touch panel sensor that disappears, includes the following steps:
A. ultra thin glass substrates 1 are cleaned；

E. two-sided photoresist demoulding；
F. ultra thin glass substrates 1 are bonded with glass cover-plate 7 with OCA6.
Ultra thin glass substrates 1 are cleaned first before 1 plated film of ultra thin glass substrates, then be splashed by vacuum magnetic control
Two-sided one-pass molding plating niobium pentaoxide layer 2 is penetrated, so that 1 upper and lower surface of ultra thin glass substrates is plated with niobium pentaoxide layer 2.Again
The two-sided one-pass molding applying silicon oxide layer 3 of vacuum magnetic-control sputtering is crossed, so that 2 surface of niobium pentaoxide layer is plated with titanium dioxide up and down
Silicon layer 3.ITO inductive layer, the top including 1 upper surface of ultra thin glass substrates are plated in the last two-sided one-pass molding of vacuum magnetic-control sputtering
The bottom ITO inductive layer 5 of 1 lower surface of ITO inductive layer 4 and ultra thin glass substrates.
By protecting to 5 photoresist of bottom ITO inductive layer, place is patterned using yellow light technique to top ITO inductive layer 4
Reason.Magnetron sputtering ITO layer generated, it can be understood as some single atoms or atomic group are packed together institute after aoxidizing
The film of formation, so it can be understood as having isotropic characteristic, that is, in light, electricity, chemistry etc. from macroscopically saying
In performance, all directions are substantially consistent.This characteristic can allow ITO inductive layer when carrying out chemical etching, Ge Gefang
To chemical reaction velocity it is all consistent, to obtain good drawing reappeared.Using this performance, by photoresist making coatings,
It can the circuitous pattern needed for ITO inductive layer surface etch.After graphical, to two-sided photoresist demoulding.
Finally, ultra thin glass substrates 1 are bonded with glass cover-plate 7 by OCA6.
