1. A display method for electronic paper label apparatus including following steps:
- a. a serial number receiving-identifying unit of a handheld device receiving a wireless serial number signal of a serial number unit of an electronic paper label apparatus;
b. the serial number receiving-identifying unit sending a serial number information to a handheld-device-side microcontroller of the handheld device after the wireless serial number signal is received by the serial number receiving-identifying unit;
c. the handheld-device-side microcontroller sending a display information corresponding to the serial number information to a short-range wireless transmitter of the handheld device after the serial number information is received by the handheld-device-side microcontroller;
d. the short-range wireless transmitter sending a wireless display signal after the display information is received by the short-range wireless transmitter;
e. a short-range wireless receiver of the electronic paper label apparatus recovering the display information and sending the display information to a label-side microcontroller of the electronic paper label apparatus after the wireless display signal is received by the short-range wireless receiver;
f. the label-side microcontroller sending the display information to an electronic paper of the electronic paper label apparatus after the display information is received by the label-side microcontroller; and
g. the electronic paper displaying the content of the display information after the display information is received by the electronic paper.

Abstract
A display method for electronic paper label apparatus first detects a serial number of an electronic paper label by a handheld device. Then a wireless display signal corresponding to the serial number is sent from the handheld device to the electronic paper label. Finally, the display content of an electronic paper of the electronic paper label is changed by the wireless display signal.
