Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
The utility model comprises the control module that is used to handle input information, the display module that is used to show input information, gathers the electromagnetic induction module of time writer input information and the capacitance touch module of gathering touch information.As Fig. 1 is functional block diagram of the present utility model.Control module is handled the input information from electromagnetic induction module and the collection of capacitance touch module, and this input information is passed to external unit, as equipment such as computing machine, embedded systems.External unit drives display module again, and the input information of the molding of automatic control in the future piece is shown on the display device of display module.
Electromagnetic induction module generally is made up of electromagnetic induction control panel and electromagnetic induction antenna plate, and the electromagnetic induction antenna plate is to electromagnetic induction control panel transmission time writer information.Its concrete principle of work is: regular directions X and the orthogonal coil of Y direction laid of electromagnetic induction antenna plate, directions X coil and Y direction coil are respectively as the radiating circuit and the receiving circuit of electromagnetic induction antenna plate, the emission electromagnetic signal also receives the resonance signal that the time writer of built-in resonance circuit produces, and the electromagnetic induction control panel calculates the position information such as coordinate, pressure and angle of inclination of time writer on the electromagnetic induction antenna plate according to the power of resonance signal.
The capacitance touch module comprises electric capacity control panel and capacitance plate.Capacitance plate is four layers of compound glass screen, and the inside surface of glass screen and interlayer respectively scribble layer of transparent conductive layer ITO, and outermost layer is the silicon soil glassivation that has only 0.0015 millimeters thick.Internal layer ITO is as screen layer, to guarantee good working environment.Interlayer ITO coating is drawn four electrodes as the working lining of detection and location on four angles or four edges.Its concrete principle of work is: when the user touched capacitance plate, because the high frequency ac signal that is connected on people's bulk electric field and the working lining, the coupling capacitance that user's finger and working lining form absorbed an alternating current.This electric current flows out from four angles of capacitance plate or the electrode on the four edges respectively, and the electric current of these four electrodes of flowing through in theory is proportional with the distance of pointing four jiaos, controller calculates by the precision to these four current ratios, draws touch point position.
Electromagnetic induction control panel and electric capacity control panel are arranged in the control module, by the input information of control module processing from electromagnetic induction control panel and the collection of electric capacity control panel.
According to the utility model first embodiment, as shown in Figure 2, capacitance plate 1 overlays the top of electromagnetic induction antenna plate 2, and electromagnetic induction antenna plate 2 overlays the display screen top of display module 3, and control module 4 is arranged on described display module 3 belows.Place electromagnetic induction control panel and electric capacity control panel in the control module 4.Capacitance plate and electromagnetic induction antenna plate are made by transparent material.
