Abstract

A display-enabled card with security authentication function includes a flexible card structure internally provided with a flexible electronic system, which includes a flexible display, a power supply module for supplying a DC voltage, a driving control module having a DC voltage converter for converting the DC voltage into a first driving voltage; a smart IC connected to the driving control module, a communication module connected to and working with the smart IC to perform security authentication, and a power management module arranged between the power supply module, the driving control module and the smart IC to provide the DC voltage to the driving control module and convert the DC voltage into a second driving voltage. The driving control module directly reads data stored in the smart IC and drives the flexible display to show the read data, so as to avoid poor sensing or data communication due to unstable voltage.

Claims

1. A display-enabled card with a security authentication function, comprising:

a flexible card structure internally provided with a flexible electronic system capable of performing security authentication;

the flexible electronic system including;

a flexible display including a display screen provided on a surface of the card structure;

a power supply module for supplying a DC voltage;

a driving control module including a first DC voltage converter for converting the DC voltage supplied by the power supply module into a first driving voltage needed by the flexible display;

a smart IC connected to the driving control module;

a communication module connected to and working with the smart IC to perform the security authentication, such that a two-way data access between the communication module and the smart IC is allowed only when the security authentication succeeds;

a power management module arranged between the smart IC, the power supply module and the driving control module to provide the DC voltage supplied by the power supply module directly to the driving control module, the power management module including a second DC voltage converter for converting the DC voltage supplied by the power supply module into a second driving voltage needed by the smart IC; and

an input module connected to the driving control module, the input module including at least one input interface located on the surface of the card structure,

wherein the driving control module directly reads out data stored in the smart IC and drives the flexible display to show the read-out data on the display screen.

2. The display-enabled card with a security authentication function as claimed in claim 1, wherein the driving control module further includes:

a driver connected to the first DC voltage converter; and

a controller connected to the driver and the smart IC for controlling the reading of the data stored in the smart IC and transmitting the read-out data to the driver, so that the driver is able to drive the flexible display to show the read-out data on the display screen.

3. The display-enabled card with a security authentication function as claimed in claim 1, wherein the power management module supplies the DC voltage to the driving control module and the smart IC only when they are reading data.

4. The display-enabled card with a security authentication function as claimed in claim 1, wherein the communication module and the smart IC are temporarily isolated from each other when the driving control module is reading out data from the smart IC and transmitting the read-out data to the flexible display, and the driving control module and the smart IC are temporarily isolated from each other during data access between the smart IC and the communication module.

5. The display-enabled card with a security authentication function as claimed in claim 1, wherein the communication module is located on the surface of the card structure to form a contact type communication means.

6. The display-enabled card with a security authentication function as claimed in claim 5, wherein the contact type communication means includes a metal contact chip.

7. The display-enabled card with a security authentication function as claimed in claim 1, wherein the communication module is embedded in the card structure to form a non-contact type communication means.

8. The display-enabled card with a security authentication function as claimed in claim 7, wherein the non-contact type communication means includes an antenna.

9. The display-enabled card with a security authentication function as claimed in claim 1, wherein the communication module forms a hybrid communication means on the card structure.

10. The display-enabled card with a security authentication function as claimed in claim 9, wherein the hybrid communication means includes a metal contact chip provided on the surface of the card structure and an antenna embedded in the card structure.

11. The display-enabled card with a security authentication function as claimed in claim 1, wherein the input interface is selected from the group consisting of a push-button mechanism and a touch sensor panel.

12. The display-enabled card with a security authentication function as claimed in claim 1, wherein the power management module and the driving control module are integrated into one single integrated circuit.

13. The display-enabled card with a security authentication function as claimed in claim 1, wherein the power management module and the smart IC are integrated into one single integrated circuit.
