Abstract

The present disclosure provides a display substrate and a display panel, and belongs to the field of display technology. The present disclosure can solve the problem of light interference during touch detection in the existing display products. The display substrate of the present disclosure includes: a light-emitting device layer configured to emit first color light; a quantum dot layer including at least a first quantum dot unit and a second quantum dot unit, where the first quantum dot unit is configured to emit second color light under excitation of the first color light, and the second quantum dot unit is configured to emit third color light under excitation of the first color light; a touch detection layer configured to determine touch information according to a received optical signal; and an auxiliary functional layer between the quantum dot layer and the light-emitting device layer; wherein the auxiliary functional layer is configured to transmit the first color light and reflect the second color light and the third color light, so that interference with the touch detection layer is reduced, and the accuracy and sensitivity of the touch detection layer are improved.
