Quality.

In FIG. 1, the ticket card 100 has a rewritable writing panel 120, such as a bistable liquid crystal panel. In one embodiment, the rewritable panel 120 writes information in a hot write manner to clear the information in an electrically cancelled manner. In the process of hot writing, the ticket card 100 generates an AC voltage via the electromagnetic induction element 110 by using electromagnetic waves or microwaves generated by the electromagnetic transmitter 220, and stabilizes the voltage by the voltage regulator 112. This voltage is written in the module 230 with heat energy. The information is applied to the rewritable panel 120 when writing information, thereby improving the contrast of information writing and the quality of information writing. The AC voltage is, for example, plus or minus 3 volts, but is not limited thereto.

Specifically, the write module 230 of the present embodiment includes a thermal write head that heats a local area on the rewritable panel 120 in a hot write manner to enable the heated area to display a ticket card 100. Information, such as text or images, such as date, house number, location, amount, number, 2D barcode, action bar code, decorative marks of various forms and designs, advertising marks or printed images, etc., but not This is limited to this. When writing to module 230 When the thermal energy is written into the information, an alternating voltage can be simultaneously applied to the rewritable panel 120 to improve the contrast of the information writing and the quality of the information writing.

As shown in FIG. 1 , the rewritable panel 120 has two electrodes 121 , 122 , such as a first electrode and a second electrode, and the two electrodes 121 and 122 are connected to the first power supply circuit 101 via the switching unit 130 . Voltage regulator 112 and electromagnetic induction element 110. The electromagnetic induction element 110 is, for example, an electromagnetic induction coil or an RF induction element, and can induce an AC power source through an electromagnetic field, and then is stabilized by the voltage regulator 112 as an input voltage of the rewritable panel 120. The voltage regulator 112 is, for example, a capacitor or consists of a transistor element.

In addition, in the process of clearing the information, the ticket card 100 receives an external power source by using the input contact 140, and connects the input contact 140 located on the second power supply circuit 102 to the rewritable writing panel 120 by using the switching unit 130. The external power supply is provided by the AC electric field module 240 and can be used as an input voltage required to clear the information.

In this embodiment, the switching unit 130 is connected between the first power supply circuit 101 and the second power supply circuit 102 for switching the internal power generated by the electromagnetic induction element 110 and the external power received by the input contact 140. Please refer to FIGS. 3A and 3B , which respectively illustrate the operation of the two switching elements 131 , 132 . In the write information process or the normal state of FIG. 3A, one end of the two switching elements 131, 132 is switched to connect the first contact X1 and the second contact Y1 of the first power supply circuit 101 to provide the information required for writing information. The voltage is, for example, the voltage supplied by the internal power source generated by the electromagnetic induction element 110. In the process of clearing information in FIG. 3B, one end of the two switching elements 131, 132 is switched to the third contact X2 and the fourth connection connecting the second power supply circuit 102. Point Y2 to provide the voltage required to clear the information, such as the voltage supplied by an external power source.

In an embodiment, the external power source provides a voltage greater than the voltage provided by the internal power source. For example, an external power supply can provide an AC voltage of approximately plus or minus 60 volts, while an internal power supply can provide an AC voltage of approximately plus or minus 3 volts. When the external power source supplies a high-power input voltage, the switching unit 130 cuts off the first power supply circuit 101 to prevent the high-power voltage from entering the first power supply circuit 101, thereby achieving the effect of isolation protection.

Therefore, the ticket card 100 of the present embodiment can switch the power source according to the voltage required to write information or clear the information. The above manner of switching the power source may be mechanical, electronic or inductive. For example, the switching element can be a mechanical switch, a push switch, an electronic switch or a magnetic field inductive switch.

The magnetic field sensing switch is, for example, a Hall sensing element. The magnetic field sensing switch can switch the power source by detecting the magnetic flux of the external magnetic field, and output the switched voltage to the rewritable panel 120. For example, when the magnetic flux of the external magnetic field is detected to be less than a predetermined value, one end of the two switching elements 131, 132 is switched to connect the first contact X1 and the second contact Y1 of the first power supply circuit 101 to provide The voltage required to write the information. When the magnetic flux of the external magnetic field is detected to be greater than a predetermined value, one end of the two switching elements 131, 132 is switched to connect the third contact X2 and the fourth contact Y2 of the second power supply circuit 102 to provide information for clearing information. Voltage. In an embodiment, the external magnetic field may be provided by electromagnetic transmitter 220 or by alternating current electric field module 240.

In the process of clearing information, the electronic switch can pass a voltage detection The component (not shown) determines whether the input voltage exceeds a predetermined threshold, and the electronic switch switches the power according to the result of the judgment. For example, before the input contact 140 inputs an external power source, a start voltage is input to the switching unit 130. When the voltage detecting component determines that the starting voltage is greater than the preset threshold, one end of the two switching elements 131, 132 is switched to connect the third contact X2 and the fourth contact Y2 of the second power supply circuit 102. Then, the voltage required to clear the information is supplied from the external power source to the rewritable panel 120. In this way, it is ensured that the electronic switch can switch the power supply under normal operation to avoid accidental touch.

The ticket card 100 and the information rewriting device 200 disclosed in the above embodiments of the present invention can be applied to an existing ticket system. The user can purchase the ticket card 100 with the rewritable panel 120 through the ticket platform, and the ticket information written on the ticket card 100 can be saved or can be eliminated or re-issued by the ticket purchasing personnel through the electric/thermal clearing mechanism. The ticket information on the ticket card 100 is written. In addition, the input contacts 140 on the ticket card 100 are exposed and flushable to conform to the existing cleaning ticket process, and the rewritable ticket card 100 is more in line with the card making process. In addition, when the ticket card 100 writes information by the magnetic transfer mechanism, the writing quality can be eliminated due to poor contact during the writing process, so as to improve the ticket quality and enhance the verification effect, and avoid the long-term ticket card 100. Problems such as shortened life due to contact wear after use.
