1. A light field display apparatus, comprising:
a display panel, comprising a plurality of sets of pixel strips extending in a first direction and arranged in a second direction, wherein the first direction intersects with the second direction, each set of pixel strips comprises a plurality of sub-pixel strips in different colors, each sub-pixel strip comprises a plurality of sub-pixels in a same color, spacing between every two adjacent sub-pixels in each sub-pixel strip in the first direction is smaller than or equal to 2 μm, each set of pixel strips is divided into a plurality of pixel islands arranged in an array in the first direction, and each pixel island comprises at least four sub-pixels extending in the first direction in each corresponding sub-pixel strip;
a light-transmitting spacer layer, located on a light-emitting side of the display panel; and
a lens structure, located on a side of the light-transmitting spacer layer facing away from the display panel, wherein the lens structure comprises a plurality of lenses arranged in an array and having a light-converging effect; wherein
a width of a view region formed by light emitted by each sub-pixel in each pixel island being propagated to a human eye through a corresponding lens is smaller than or equal to a pupil diameter, and a distance between centers of view regions formed by light emitted by adjacent sub-pixels in each pixel island being propagated to the human eye through the corresponding lens is smaller than or equal to a pupil radius; and
a width of an orthographic projection of each pixel island on the display panel is equal to an aperture of the corresponding lens in the first direction.
