Claim 0:
1. A display panel, having a first display region and a second display region and comprising:
a base substrate;
a pixel circuit layer on the base substrate, wherein the pixel circuit layer is arranged in the second display region and comprises a plurality of pixel circuits; and
a light-emitting device layer, arranged on one side, facing away from the base substrate, of the pixel circuit layer;
wherein the light-emitting device layer comprises a plurality of active light-emitting devices and a plurality of passive light-emitting devices; the plurality of active light-emitting devices are arranged in the second display region; each of the plurality of pixel circuits is electrically connected with at least one of the plurality of active light-emitting devices; and the plurality of passive light-emitting devices are arranged in the first display region in an array mode;
wherein the first display region comprises: a plurality of first sub-display regions which are configured to be driven separately to make the first display region display an image;
wherein each of the plurality of first sub-display regions further comprises: a plurality of first driving lines and a plurality of second driving lines;
wherein cathodes of passive light-emitting devices in one column are electrically connected with one of the plurality of first driving lines; anodes of passive light-emitting devices in one row are electrically connected with one of the plurality of second driving lines; and the second driving lines in different first sub-display regions are arranged at intervals;
wherein the display panel further comprises: a plurality of first pixel units arranged in an array mode in the first display region; wherein the first pixel units comprise first color sub-pixels, second color sub-pixels and third color sub-pixels; and one of the passive light-emitting devices is arranged in each of the first color sub-pixels, the second color sub-pixels and the third color sub-pixels in the first display region respectively;
anodes of the passive light-emitting devices in a same color sub-pixel in one row are electrically connected with one of the plurality of second driving lines; the cathodes of the passive light-emitting devices in one column of the first pixel units are electrically connected with one of the plurality of first driving lines; and
signals input into the first driving lines of each of the first sub-display regions at a same moment are identical, and signals input into the second driving lines of each of the first sub-display regions at a same moment are identical.
