摘要： An array substrate may include a dielectric layer (1), a plurality of pixel units (2) on the dielectric layer (1), auxiliary light emitting elements (3), and a fingerprint recognition layer (4) on a side of the dielectric layer (1) opposite from the pixel units (2). Each of the pixel units (2) may comprise transparent display elements (21). The fingerprint recognition layer (4) may comprise fingerprint recognition elements (41). The fingerprint recognition elements (41) may be configured to receive light emitted by the auxiliary light emitting elements (3) and reflected by a touch control body (10) to identify fingerprint information.
