Abstract

The invention provides an intelligent display card and an operation method thereof. The intelligent display card comprises a connection interface, a safety chip and a processing chip. The connection interface is used for receiving a power supply signal and a data signal provided by an external card reader when the intelligent display card is connected with the external card reader. The security chip is coupled to the connection interface and receives the power supply signal and the data signal. The security chip conforms to a first communication protocol. The processing chip is coupled to theconnection interface and receives the power supply signal and the data signal. The processing chip conforms to a second communication protocol. The first communication protocol is different from the second communication protocol. The display couples with the processing chip. The processing chip drives the display according to the power supply signal and the data signal.

Description

technical field [0001] The invention relates to a smart card (Smart Card), in particular to a smart display card and an operating method thereof. Background technique [0002] Generally speaking, smart display cards can be divided into two types: those without batteries and those with batteries. For traditional smart display cards without batteries, Near Field Communication (NFC) is mainly used for wireless power supply, but the disadvantage is that the usable area of ​​the card will affect the antenna design of NFC. Moreover, due to the low energy of the wireless power supply of the NFC, the display size and resolution of the smart display card are limited by the power supply capability of the NFC. Therefore, the battery-less smart display card has relatively high design difficulty and manufacturing cost. In addition, in the traditional smart display card, the driver chip for driving the display is added at the back end of the security chip, so as to obtain data and power...
