Abstract
A light emitting substrate is provided. The light emitting substrate includes a plurality of driver chip sets, a plurality of ground traces, and one or more connection lines. At least one driver chip set includes a plurality of driver chip subsets, at least one driver chip subset includes a plurality of driver chips that are cascaded, and driver chip subsets in a same driver chip set are cascaded. Driver chips in a same driver chip subset are electrically connected to a same ground trace, and different driver chip subsets are respectively connected to different ground traces. Ground traces respectively connected to the driver chip subsets in the same driver chip set are electrically connected by at least one connection line.
