Abstract

A display panel includes a first display region and a second display region. The light transmittance of the first display region is greater than the light transmittance of the second display region. The first display region includes a plurality of first sub-pixels. At least one of the first sub-pixels includes an electrode group. The electrode group includes a first electrode and a second electrode. In the first direction, the orthographic projection of the first electrode at least partially overlaps the orthographic projection of the second electrode. The first direction is parallel to the light-emitting surface of the display panel. In the stage of capturing, the voltage difference between the first electrode and the second electrode is greater than zero volts. The phase of a voltage difference of the first electrode to the second electrode is reversed as a frame is reversed.
