Display panel, display device, and driving method for display panel

A display panel, comprising:

• a base substrate;
• a display structure layer on a side of the base substrate;
• wherein the display structure layer comprises a plurality of sub-pixels;
• at least one of the plurality of sub-pixels comprises:
• a pixel circuit and a light-emitting element electrically connected to the pixel circuit;
• the light-emitting element comprises:
• a first light-emitting unit and a second light-emitting unit;
• a light-emitting region of the first light-emitting unit is isolated from a light-emitting region of the second light-emitting unit;
• an optical component on a light-emitting side of the display structure layer;
• wherein the optical component comprises:
• a first optical film layer, and a second optical film layer on a side of the first optical film layer away from the base substrate;
• an refractive index of the second optical film layer is greater than an refractive index of the first optical film layer;
• the first optical film layer is provided with an isolation portion and a plurality of openings;
• an orthographic projection of the opening on the base substrate at least partially overlaps with an orthographic projection of the light-emitting region of the first light-emitting unit on the base substrate.
