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.

Abstract: A display device includes an active display array, an optical sensor array, a first driving circuit, a second driving circuit, and a third driving circuit. The active display array includes a number of scan lines. The first driving circuit is coupled to a first portion of the scan lines through a first metal layer. The second driving circuit is coupled to a second portion of the scan lines through the first metal layer. The third driving circuit is disposed between the first driving circuit and the second driving circuit and is coupled to the optical sensor through a second metal layer. The second metal layer is different from the first metal layer.
