The display element is disposed on the card body. The second integrated circuit transmits to-be-displayed information to the display element. The display element displays an image according to the to-be-displayed information. In addition, a method for operating a proximity smart card is also provided.

Proximity smart card and method for operating proximity smart card

An electronic paper display apparatus, a signal transmission system and a method thereof are provided. The electronic paper display apparatus is configured to transmit an encrypted signal. The electronic paper display apparatus includes an electronic paper display panel and a display driver. The electronic paper display panel is configured to display a first image or a second image. The display driver is electrically coupled to the electronic paper display panel and configured to output a driving signal to the electronic paper display panel. The display driver drives the electronic paper display panel to alternately display the first image and the second image for transmitting the encrypted signal by using the driving signal during a signal transmission period.

Electronic paper display apparatus, signal transmission system and method thereof

An electronic paper apparatus including a communication module and a control module is provided. The communication module receives an electrical signal and generates a power voltage according to the electric signal. The communication module wakes up a controller during a first period of a work period by using the power voltage. The control module is electrically connected to the communication module, and includes the controller and an electronic paper display. The control module establishes a communication connection with the communication module during a second period of the work period. The power circuit module generates a driving voltage according to the power voltage to drive the electronic paper display to display image information according to the driving voltage during a display period. The first period and the second period are two continuous time intervals forming the work period. Furthermore, a driving method of the electronic paper apparatus is also provided.
