Abstract
A display panel having a first display region and second display region is provided. The display panel includes a sub-pixel array that includes a plurality of sub-pixels in an array and distributed in the first display region and the second display region. A non-light-emitting region in the second display region has a greater light transmittance than a non-light-emitting region in the first display region. Among sub-pixels emitting a same color of the plurality of sub-pixels in the first display region and the second display region, a width-to-length ratio of a driving transistor in the pixel circuit of a sub-pixel in the second display region is greater than a width-to-length ratio of a driving transistor in the pixel circuit of a sub-pixel in the first display region.
