Methods of preparing lens arrays, display apparatuses, and methods of preparing display apparatuses

A display apparatus, comprising:

• a base substrate;
• a plurality of sub-pixels arranged in an array and located on the base substrate, a non-display area existing between adjacent sub-pixels;
• a hybrid film located on a side of the plurality of sub-pixels arranged in an array away from the base substrate, wherein the hybrid film comprises first hybrid sub-films arranged in an array and a second hybrid sub-film, and a contact angle of a liquid on a surface of the first hybrid sub-film is less than a contact angle of the liquid on a surface of the second hybrid sub-film;
• and a projection of the sub-pixels on the base substrate is located within a projection of the first hybrid sub-films on the base substrate, and a projection of the second hybrid sub-film on the base substrate is located within a projection of the non-display area on the base substrate;
• and
• lenses arranged in an array and respectively located on the first hybrid sub-films.
