A driving method of an electronic paper display apparatus, including: inputting, by a controller, a first driving signal to a pixel electrode of a pixel driving circuit corresponding to a pixel which is required to display black, according to an image to be displayed; and inputting, by the controller, a second driving signal to a pixel electrode of a pixel driving circuit corresponding to a pixel which is required display white, according to the image to be displayed. A driving stage of the electronic paper display apparatus comprises a first homogenization stage which comprises a plurality of homogenization sub-stages. At a last homogenization sub-stage, the first and second driving signals comprise first and second driving sub-signals, respectively. Voltages of the first driving sub-signal and the second driving sub-signal have polarities opposite to polarities of the black particles and the white particles, respectively.

Electronic paper display apparatus, driving method thereof and computer-readable storage medium

A display method of an electronic identification device, a controller, an electronic identification device and a system are provided. The display method includes: controlling the electronic identification device to enter a working state from a sleep state, and obtaining to-be-displayed data; power consumption corresponding to the electronic identification device in the sleep state being lower than power consumption corresponding to the electronic identification device in the working state; and refreshing the to-be-displayed data to an electronic ink screen for display through a serial peripheral interface bus, and controlling the electronic identification device to enter the sleep state again after the refreshing is completed.

Display method of electronic identification device, controller, electronic identification device and system

A control method for an electronic ink screen includes: when colors of an image to be displayed include only a black color and a white color, outputting a first black driving signal, and outputting a first white driving signal; and when the colors of the image to be displayed include the black color, the white color and a chromatic color, outputting a second black driving signal, outputting a second white driving signal, and outputting a chromatic driving signal. A duration of the first black driving signal is equal to a duration of the first white driving signal. A duration of the second black driving signal, a duration of the second white driving signal and the duration of the chromatic driving signal are equal. The duration of the second white driving signal is greater than the duration of the first white drive signal.
