Abstract: The present disclosure relates to a display apparatus, a display drive circuit and a driving method of an electronic paper display unit, which relates to the field of display technology. The display drive circuit includes a display control circuit, the display control circuit includes a capacitor unit, a radio frequency circuit, a voltage collection circuit, and a control circuit. The radio frequency circuit includes an induction circuit and a communication circuit. The induction circuit can charge the capacitor unit in response to a radio frequency signal of the terminal device. The collection circuit can collect the voltage of the capacitor unit. The control circuit can perform the transmission action when the voltage of the capacitor unit reaches an operating threshold voltage of the electronic paper display unit; turn off the voltage collection circuit and the communication circuit after the transmission action is completed.
