Abstract
The utility model relates to an electromagnetic handwritten signature device, which is characterized by comprising a central control unit, wherein the central control unit is connected with a thin film transistor (TFT) display screen through red green blue (RGB) data lines, a vertical scanning line, a horizontal scanning line and a point frequency line, output control signals of the central control unit are connected with a back light drive circuit, a light emitting diode (LED) back light of the TFT display screen is driven by the back light drive circuit in a boosting mode, and the central control unit is further connected with an electromagnetic contact module of an electromagnetic contact screen. Therefore, the electromagnetic handwritten signature device has the advantages that 1 the TFT display screen with high resolution can display more content; 2 a 1670 million true color screen breaks the design constraints of traditional financial monochromatic interfaces; 3 the electromagnetic contact screen supports high precision touch, highly returns handwritten signature, and achieves the identification purpose of handwritten signature; and 4 the electromagnetic handwritten signature device can increase the function of handwritten signature through the contact screen, and is beneficial for promotion of electronic signature application.
Description
Technical field
The utility model relates to a kind of handwritten signature equipment that is used on the financial terminal.
Background technology
At present, behind the bankcard consumption, after need to document being printed by financial terminal, signed at document by the consumer, such shortcoming is again, the waste paper, and Unionpay transfers single process too loaded down with trivial details and frequent.Along with the resolution of electronic product screen is more and more higher, screen size is increasing, and the functions such as touch, handwriting input are used day by day universal, becomes possibility on the financial terminal so that electronic signature is applied in.
Summary of the invention
The purpose of this utility model provides a kind of equipment of signing electronically by financial terminal can realized.
In order to achieve the above object, the technical solution of the utility model has provided a kind of electromagnetic type handwritten signature equipment, it is characterized in that: comprise central control unit, central control unit is by frequently line connection of RGB data line, vertical scan line, horizontal scanning line and some TFT display screen, the output control signal of central control unit connects backlight drive circuit, by the boost LED-backlit of drive TFT display screen of backlight drive circuit, central control unit also connects the electromagnetic touch module of electromagnetical type touch screen.
Preferably, described central control unit connects the memory module that is used for the storage signed data by data line, address wire and read-write control signal.
Preferably, described central control unit connects financial terminal by serial ports, by serial ports the handwritten signature image data is sent to financial terminal by central control unit, thereby realizes the printing of signed data.
A kind of electromagnetic type handwritten signature equipment that the utility model provides has large scale TFT display screen, it can show abundant picture and Word message, increased simultaneously the electromagnetical type touch screen of high touch sensitivity as input equipment, so that operation interface is more humane, meet the user's signature use habit fully.
Therefore, the utlity model has following advantage:
1) high resolving power TFT display screen, screen can show more contents;
2) 1,670 ten thousand true color screen, the design constraint at the financial monochromatic interface that breaks traditions;
3) electromagnetical type touch screen is to the support of high precision touch-control, highly reduces handwritten signature, reaches the purpose of handwritten signature identification;
4) can increase the handwritten signature function by touch-screen, be conducive to the popularization that signs electronically and use.
Description of drawings
The circuit block diagram of a kind of electromagnetic type handwritten signature equipment that Fig. 1 provides for the utility model;
The use connected system figure of a kind of electromagnetic type handwritten signature equipment that Fig. 2 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, a kind of electromagnetic type handwritten signature equipment that the utility model provides comprises central control unit, and central control unit is by frequently line connection of RGB data line, vertical scan line, horizontal scanning line and some TFT display screen.The color depth of TFT display screen is 1,670 ten thousand, and resolution is 240 * 320 (QVGA), is of a size of 3.5 ".The output control signal of central control unit connects backlight drive circuit, and by the boost LED-backlit of drive TFT display screen of backlight drive circuit, it is 6LED series current type of drive that LED-backlit drives, and screen intensity is controlled.Central control unit also connects the electromagnetic touch module of electromagnetical type touch screen.Central control unit also connects the memory module that is used for the storage signed data by data line, address wire and read-write control signal.
During use, as shown in Figure 2, central control unit is connected financial terminal by serial ports, financial terminal contacts by cable network or wireless network and Unionpay backstage, by serial ports the handwritten signature image data is sent to financial terminal by central control unit, thereby realizes the printing of signed data.
The course of work of the present utility model is: writing pencil is converted to Serial Port Information at the signed data of electromagnetical type touch screen through the electromagnetic touch module and sends to central control unit.Central control unit outputs to the TFT display screen by RGB and three scan line and shows the signature picture, by data line, address wire and the corresponding read-write control line that links to each other with storage unit signing messages is stored in the storage chip simultaneously, prints such as need and then send financial terminal printed signature picture to by serial communication interface.Central control unit is controlled backlight drive circuit according to default brightness value, and backlight drive circuit drives and control the LED-backlit of TFT display screen by boosting and current feedback.
Touch-screen specific works process is: the electromagnetic touch module is experienced in the handwritten signature moving process by contrast and is shielded corresponding electromagnetic change with electromagnetic touch, and this variation is converted to screen location information is sent to main frame by serial mode.After central control unit obtains these values, judgement has signature or Action Events to occur, and this information and display system is connected at certain point of screen, allow client's the intuitional and experiential thinking oneself operation or see signature contents, perhaps this information is stored to corresponding memory module.
