Abstract: A display device including a display panel that includes a plurality of micro-LED pixel units arranged in an array, and a light-controlling component disposed on a light exiting side of the display panel. The light-controlling component includes a plurality of light-controlling regions each including at least two sub-regions individually controllable to switch between a transmissive state and a non-transmissive state. The light-controlling regions are arranged such that an orthographic projection of each of the light-controlling regions on the display panel covers a respective one of the micro-LED pixel units.

Abstract: The present disclosure provides a photoelectric sensor, an array substrate, a display panel and a display device. The photoelectric sensor is used for fingerprint recognition, and includes a first electrode layer, being lighttight. The photoelectric sensor further includes a first transparent electrode layer, disposed opposite to the first electrode layer and receiving incident light, and a light sensing layer, located between the first electrode layer and the first transparent electrode layer. The light sensing layer includes a plurality of nanocrystalline silicon particles with different particle sizes.
