Abstract:
A display apparatus includes: a pixel array section and dependence cancellation means. The pixel array section wherein a plurality of pixel circuits each including an electro-optical element, a driving transistor configured to drive said electro-optical element, a sampling transistor configured to sample and write an input signal voltage and a capacitor configured to hold a gate-source voltage of said driving transistor within a display period are disposed in a matrix. The dependence cancellation means for negatively feeding back, within a correction period before said electro-optical element emits light in a state wherein the input signal voltage is written by said sampling transistor, drain-source current of said driving transistor to the gate input side of said driving transistor to cancel the dependence of the drain-source current of said driving transistor on the mobility.
