Abstract:
A display device adapted to perform in-screen fingerprint identification is provided. The display device includes a plurality of sub-pixel circuits, a plurality of light sensing circuit stages, and a plurality of sensing drive lines. The light sensing circuit stages correspond to the sub-pixel circuits. The sensing drive lines drive the light sensing circuit stages sequentially. In a first time interval, a first sensing drive line among the sensing drive lines provides a first sensing drive signal to a qth light sensing circuit stage and a latter light sensing circuit stage among the light sensing circuit stages. In the first time interval, the qth light sensing circuit stage performs a light sensing reset operation according to the first sensing drive signal, and the latter light sensing circuit stage performs a light sensing write operation according to the first sensing drive signal.
