Abstract
An electrophoretic display panel includes a first substrate, electrophoretic particles, a scan line, a data line, and a pixel. The scan line, the data line, and the pixel are located on the same side of the first substrate facing the electrophoretic particles. The scan line is configured to transmit a scan signal to the pixel. The data line is configured to transmit a data signal to the pixel, and a data signal includes multiple unit periods. In a write state in a drive stage of the electrophoretic display panel, the data signal includes a drive signal and at least one adjustment signal inserted into the drive signal and configured to divide the drive signal into at least two drive sub-signals, and a voltage of a drive sub-signal of the at least two drive sub-signal is different from a voltage of an adjustment signal in a unit period.
