Abstract
A display panel and a temperature regulation method for a display panel are provided. The display includes a substrate, a thin film transistor layer, a first passivation layer, a photoelectric detector, a first light-shielding layer, and a second light-shielding layer. The first light-shielding layer is disposed on one side of the photoelectric detector away from the substrate. The second light-shielding layer is disposed on the lateral of the photoelectric detector.
