Abstract:
1. A photo-detecting pixel comprising: a photosensitive device for generating a first detection signal by photoelectrically converting incident light; a first transistor for generating a detection current by receiving the first detection signal generated by the photosensitive device via a gate terminal of the first transistor; a second transistor for forming a first current path with the first transistor, in response to a read signal input via a gate terminal of the second transistor; and a third transistor for delivering a voltage in accordance with the detection current to a data line, in response to a gate signal applied to a gate terminal of the third transistor, wherein the first transistor has the gate terminal connected to a first node that is connected to a terminal of the photosensitive device, a first terminal connected to a first power, and a second terminal connected to a second node, the second transistor has the gate terminal connected to a read signal line for delivering the read signal, a first terminal connected to the second node, and a second terminal connected to a second power, and the third transistor has the gate terminal connected to a gate line for delivering the gate signal, a first terminal connected to the second node, and a second terminal connected to the data line.
