1. An optical detection apparatus for detecting a display panel, comprising photosensitive units arranged in an array, wherein a minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel, and the photosensitive units in adjacent rows have a position offset in a first direction, an offset distance corresponding to the position offset being less than the sub-pixel size of the display panel;
wherein a pitch between adjacent photosensitive units is N times the minimum distance between the adjacent photosensitive units, N being an integer greater than or equal to 2; and the pitch between adjacent photosensitive units is an integral multiple of the offset distance, wherein the pitch between the adjacent photosensitive units is a distance between center points of the adjacent photosensitive units.
