Accompanying drawing explanation
Fig. 1 is the module connection diagram of the present invention；
Fig. 2 is the Rotating fields schematic diagram of the present invention；
In figure, 1 is Glass layer, and 2 is ink layer, and 3 is ITO layer or nano-silver layer, and 4 is optical cement, and 5 is PET substrate.
Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings；
As shown in the figure: G1F structure be the thin film of the glass+band transparency conducting layer of one-side band transparency conducting layer touch
Screen.The capacitive touch screen of G1F structure is broadly divided into lower part: touch sensing unit, touch screen controller and host CPU.Its
Middle touch sensing unit is made up of GLASS Sensor and Film Sensor, and wherein Glass Sensor is first at GLASS
One layer of ink of upper plating, produces the panel effect required for client, plates one layer of ITO or nanometer silver transparency conducting layer the most again, is formed
Glass Sensor。
Ground floor GLASS layer can be 0-2mm, and common used material has: Merlon, lucite and glass.
Second layer ink marking layer thickness is generally within 2um, and this layer is positioned over below layer, can with buried wirring and
The edge of LCD.
Third layer sensing unit layer, generally uses ITO or nanometer silver coating, and thickness is less than 10um, the figure of sensing unit
Be by touch screen controller determine, produced by etching required for figure.
4th layer of optical cement, its thickness is typically at 100-175um, it is possible to achieve the laminating of Glass and Film, forms electricity mutually
The capacitive touch screen sensor of appearance scheme.
Layer 5 is Film, and its base material used is PET, and the material that transparency conducting layer uses is ITO or nanometer silver, total thickness
Degree is general at 55-, and the figure of its sensing unit is also to be determined by the controller of touch screen, produced by etching required for figure
Shape.
The operation principle of the G1F structure of the invention is: by Glass Sensor and Film Sensor by one layer
Optical cement is fitted, and forms mutual capacitance, when the finger of people touches, owing to human body has siphoned away a part of electric capacity, and therefore mutual capacitance
Amount will reduce, and IC controller passes through analog to digital conversion, and this analog quantity is converted into digital quantity, then by this digital quantity and no touch
Time amount compare, such digital quantity changes, and thinks and now has finger to touch, and simultaneously by software processes, must sell
Refer to touch-control position coordinates, during added wave filter, exclude interference signal.Then IC control unit passes through IIC
Communication modes communicates with mainboard, produces interrupt signal, and board unit carries out the process of interrupt signal, accepts touch screen simultaneously
The position coordinates that controller is given.
The G1F structure condenser type touch screen that the present invention provides, its touch sensing unit has Glass Sensor and FILM
Sensor forms, and the transparency conducting layer that this two-layer Sensor uses is ITO or nanometer silver, does not lose other transparent conductive materials
Protection.
The present invention provides a kind of G1+F structure condenser type touch screen, including touch sensor part, chip controls part and
Mainboard control unit.Touch sensor part is made up of Glass Sensor and Film Sensor, simultaneously in this two-layer after etching
Form certain pattern on conducting film, at edge printing silver slurry wire, be connected to bind on PAD, realize touch screen by binding
The connection that sensor controls with touch screen, is made whether the judgement touched, is obtained by software processes simultaneously by touch screen controller
To the position coordinates of finger touch, then this signal is delivered to mainboard control unit.
The G1+F structure condenser type touch screen that this invention provides, its principle realized: by GLASS Sensor and Film
Both Sensor conductive materials forms mutual capacitance, and when finger touches, the mutual capacitance between both will reduce, and pass through A/D
Conversion, is converted into digital signal, and touch screen controller is through the judgement that this principle realizes touching finger.
