Abstract

The present disclosure provides a display substrate, including: a base substrate having an opening region, a transition region surrounding the opening region and a pixel region surrounding the opening region; at least one ink-jet printing dam in the transition region and surrounding the opening region; and at least one conductive film layer in the transition region, where an orthographic projection of the conductive film layer on the base substrate is overlapped with an orthographic projection of the ink-jet printing dam on the base substrate. In the technical solution of the present disclosure, the conductive film layer is intended to absorb and conduct heat, so as to reduce the heat on the ink-jet printing dam.
