Abstract

A display panel having a first display region and a second display region is provided. The display panel includes sub-pixels. Light transmittance of a non-light-emitting region in the second display region is greater than light transmittance of a non-light-emitting region in the first display region. For a first sub-pixel of the sub-pixels located in the first display region and a second sub-pixel of the sub-pixels located in the second display region that emit a same color, the first sub-pixel corresponds to a first pixel circuit, and the second sub-pixel corresponds to a second pixel circuit, and a width-to-length ratio of a driving transistor in the second pixel circuit is greater than a width-to-length ratio of a driving transistor in the first pixel circuit.
