Pixel circuit, display apparatus, and pixel circuit drive control method
Abstract:
A pixel circuit including a light emitting element, a driving transistor, connected to the light emitting element, that applies a drive current to the light emitting element, a holding circuit connected to a gate terminal of the driving transistor, and a switching transistor connected between the holding circuit and a data line through which a data signal to be held by the holding circuit flows, in which the driving transistor and the switching transistor are inorganic oxide thin film transistors whose OFF-operation threshold voltage is a negative voltage, and the holding circuit includes a first capacitor element connected between the switching transistor and the gate terminal of the driving transistor, and a second capacitor element connected between a point located between the first capacitor element and the gate terminal of the driving transistor and a voltage source that supplies a negative voltage.
