摘要 |
A sensor circuit or a display apparatus from which a highly accurate sensor output can be obtained includes a photodiode, a capacitor that is connected to the photodiode via an accumulation node and accumulates charges according to an electric current in the photodiode; a sensor switching element transistor that causes the accumulation node and an output line to be conductive with respect to each other in response to a readout signal and outputs an output signal according to the potential of the accumulation node to the output line; a variable capacitor that is provided between the accumulation node and an input electrode, and whose capacitance varies when a pressure is applied by a touching operation; and a control switching element transistor to which a control signal for switching conduction and non-conduction between the variable capacitor and the accumulation node is input.
