Display panel and mobile terminal with crack-mitigating encapsulation structure
A display panel and a mobile terminal are provided. The display panel includes a substrate and multiple barrier units spaced apart from each other in a peripheral area, openings defined between adjacent barrier units, and a first array encapsulation unit and a second array encapsulation unit separate from each other.
