Display panel, display apparatus, and preparation method for display panel

A display panel, which comprises a first active area and a second active area adjacent to the first active area, the display panel further comprising:

• a substrate;
• at least an isolation structure located on the substrate, wherein the at least an isolation structure encircles a plurality of isolation openings, and the isolation structure comprises a first layer and a second layer located on a side of the first layer that faces away from the substrate, the second layer comprising a protrusion that protrudes relative to the first layer;
• and
• a light-emitting layer located on the substrate, the light-emitting layer comprising a plurality of light-emitting units located in the isolation openings,
• wherein a width of the protrusion corresponding to designated light-emitting units of the plurality of light-emitting units in the second active area is less than or equal to a width of the protrusion corresponding to other light-emitting units in the first active area that emit the same color as the designated light-emitting units.

A display panel, which comprises a first active area and a second active area, wherein the first active area has a light transmittance less than a light transmittance of the second active area, the display panel comprising:

• a substrate;
• at least an isolation structure located on the substrate, wherein the at least an isolation structure encircles a plurality of isolation openings;
• a light-emitting layer located on the substrate, the light-emitting layer comprising a plurality of light-emitting units located in the isolation openings;
• and
• a first electrode layer located on a side of the light-emitting layer that faces away from the substrate, the first electrode layer comprising a plurality of first electrodes spaced apart from each other, wherein the first electrodes are electrically connected to the at least an isolation structure;
• and
• among the corresponding first electrodes where the light-emitting units of the same color are located, a climbing height, on the at least an isolation structure, of the first electrode located in the first active area is less than or equal to a climbing height, on the at least an isolation structure, of the first electrode located in the second active area.
