1results about How to "Improve PPI" patented technology

This application discloses a display panel and a display device. The display panel includes a substrate and an isolation structure. The isolation structure is disposed on one side of the substrate and encloses a plurality of isolation openings, including interconnected main isolation openings and auxiliary isolation openings. The display panel has an isolation cross region located between at least three adjacent main isolation openings. The auxiliary isolation openings extend from the main isolation openings toward the isolation cross region and are at least partially located within the isolation cross region. Each isolation cross region has at most one auxiliary isolation opening. This application can compress the size of the isolation structure between adjacent isolation openings, increase the PPI of the display panel, and thus improve the performance of the display panel.
