Display panel and formation method thereof, and display apparatus

A formation method of a display panel, wherein the display panel includes a plurality of sub-pixels, wherein a sub-pixel of the plurality of sub-pixels include a first sub-pixel, a second sub-pixel, and a third sub-pixel;

• at least the first sub-pixel includes a first main sub-pixel and a first interference sub-pixel;
• and the first interference sub-pixel at least partially surrounds the first main sub-pixel, the method comprising:
• providing a substrate;
• forming a pixel defining layer and a light-emitting structure on the substrate, wherein the light-emitting structure is in an opening of the pixel defining layer;
• forming an encapsulation layer on a side of the light-emitting structure away from the substrate;
• and
• at a position corresponding to the first interference sub-pixel, forming a light guide structure on a side of the encapsulation layer away from the substrate, wherein an orthographic projection of the light guide structure on a plane of the substrate is at least partially overlapped with an orthographic projection of the light-emitting structure on the plane of the substrate;
• and
• the light guide structure includes a light-blocking layer.

A display apparatus, comprising:

• a display panel, comprising:
• a plurality of sub-pixels, wherein a sub-pixel of the plurality of sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel;
• the first sub-pixel, the second sub-pixel, and the third sub-pixel emit light of different colors;
• the sub-pixel of the plurality of sub-pixels includes a substrate, a light-emitting structure on a side of the substrate, and an encapsulation layer on a side of the light-emitting structure away from the substrate;
• at least the first sub-pixel includes a first main sub-pixel and a first interference sub-pixel;
• and the first interference sub-pixel at least partially surrounds the first main sub-pixel;
• and
• a display mode and an anti-peep mode during operation, wherein:
• in the display mode, the first main sub-pixel emits light, and the first interference sub-pixel does not emit light;
• and
