    Abstract: A key, a lock core and a lock, relating to a key, a lock core and a lock are provided. The key includes: a column body, a first end of the column body being provided with a light emitting component; a first cathode component disposed on the column body and connected to one end of the light emitting component to be mated with a second cathode component in the lock core; a first piezoelectric electrode disposed on the column body and connected to the other end of the light emitting component to be pressed against a second piezoelectric electrode in the lock core. When the first cathode component is mated with the second cathode component in the lock core, and the first piezoelectric electrode is pressed against the second piezoelectric electrode in the lock core, a piezoelectric current is generated, to cause the light emitting component to emit light.

    Abstract: An array substrate having a plurality of pixel units arranged in an array where each pixel unit has a first switching structure, a second switching structure, a first pixel electrode, and a second pixel electrode. The first switching structure has a first gate, a first source, a first drain, and a first active layer located between the first source and the first drain; the first gate is on a side of the first active layer. The first pixel electrode is on a side of the first active layer away from the first gate and electrically connected to the first drain. A projection of the first pixel electrode on a plane where the first active layer resides at least partially overlaps with the first active layer; a projection of the second pixel electrode on a plane where the second active layer resides does not overlap with the second active layer.
