Abstract
A display panel has a pattern recognition region. The display panel includes a heat dissipation film, a connection portion, and a conductive portion. The heat dissipation film includes an adhesive layer, a heat conduction layer, and a conductive layer that are away from a display substrate in sequence. The heat dissipation film further includes a pattern recognition hole penetrating the adhesive layer, the heat conduction layer, and the conductive layer. A surface of the connection portion away from the display substrate is exposed by the pattern recognition hole. The connection portion is included in the display substrate, or is located outside the display substrate. The conductive portion is disposed at least on a hole wall of the pattern recognition hole, and an end of the conductive portion is connected to the conductive layer, and another end of the conductive portion is connected to the connection portion.
