Abstract: An optical detection apparatus and method for detecting a display panel is provided. The apparatus includes photosensitive units arranged in an array. A minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel; the photosensitive units in adjacent rows have a position offset in a first direction; and an offset distance corresponding to the position offset is less than the sub-pixel size of the display panel.

Abstract: A fingerprint identification module is provided. The fingerprint identification module includes: a base substrate, a first conductive layer, and a third conductive layer that are laminated sequentially. The first conductive layer includes a first signal line and a second signal line, wherein the first signal line extends along a first direction and is connected to a gate of a reset transistor in a pixel sensing circuit, and the second signal line extends along the first direction and is connected to a gate of a switch transistor in the pixel sensing circuit. The third conductive layer includes a first conductive portion configured to form a first electrode of a photodiode in the pixel sensing circuit, wherein an orthographic projection of the first conductive portion on the base substrate does not overlap with orthographic projections of the first signal line and the second signal line on the base substrate.
