Abstract
Provided are a display panel and an electronic device. The display panel includes a first substrate and a second substrate. The display panel further includes a rubber frame, a hydrophobic structure, and a drainage structure. An outer peripheral side of the rubber frame, the first substrate, and the second substrate define an accommodation space. The hydrophobic structure is disposed in the accommodating space, and the hydrophobic structure defines a buffering space and a drain outlet communicating with the buffering space. The drainage structure includes a water collecting layer, a first electrode, and a second electrode. The water collecting layer is configured to condense water vapor entering the buffering space into a water drop. The first electrode and the second electrode are configured to receive a control signal having a predetermined voltage difference to control the water drop to move toward the drain outlet.
