Display Panel and Manufacturing Method Therefor, Display Screen, and Electronic Device

An electronic device, comprising:

• an optical device;
• and
• a display screen comprising a cover plate and a display panel that comprises:
• a thin film transistor backplane;
• an organic layer;
• and
• a packaging layer, wherein the thin film transistor backplane, the organic layer, and the packaging layer are successively stacked,
• wherein the display panel includes a through hole through the thin film transistor backplane, the organic layer, and the packaging layer,
• wherein the display panel has a non-display area and a display area, the non-display area being disposed around the through hole and the display area being disposed around the non-display area,
• wherein the organic layer comprises a first organic layer and a second organic layer,
• wherein the first organic layer is partially located in the display area,
• wherein the second organic layer is partially located in the non-display area,
• wherein the first organic layer comprises a plurality of display devices,
• wherein the second organic layer includes a first groove that runs through the second organic layer,
• wherein the first groove is disposed around the through hole,
• wherein the packaging layer covers the organic layer and is filled in the first groove,
• wherein the optical device corresponds to the through hole,
• wherein the optical device is configured to acquire a light ray passing through a transparent area and the through hole, and
• wherein the cover plate is laminated to the display panel.
