Patent ID: 8823693

Claim:
A display device, comprising: a luminescence element including a first electrode and a second electrode; a capacitor which holds a voltage; a driver which includes a gate electrode connected to a first electrode of the capacitor, and a source electrode connected to the first electrode of the luminescence element, and which supplies a drain current corresponding to the voltage held in the capacitor to the luminescence element so that the luminescence element produces luminescence; a power source line for supplying a reference voltage which defines a voltage value of the gate electrode of the driver for placing the luminescence element in an OFF state; a first switch which supplies the reference voltage to the gate electrode of the driver; a data line for supplying a signal voltage and a predetermined reset voltage; a second switch which includes one of terminals connected to the data line, and an other of the terminals connected to a second electrode of the capacitor, and which switches between conduction and non-conduction between the data line and the second electrode of the capacitor; and a drive circuit which controls the first switch and the second switch, wherein the drive circuit: turns ON the first switch during a first portion of a reset period so that the reference voltage is supplied to the gate electrode of the driver and the luminescence element is placed in the OFF state; turns ON the second switch during the first portion of the reset period in which the first switch is ON so that the predetermined reset voltage is applied from the data line to a connection point between the first electrode of the luminescence element and the source electrode of the driver; turns OFF the first switch and the second switch during a second portion of the reset period after the first portion, after turning ON the second switch during the first portion of the reset period; turns ON the first switch again during a write period different than the reset period after turning OFF the first switch and the second switch during the second portion of the rest period; and turns ON the second switch again during the write period in which the first switch is ON again so that the signal voltage is applied to the second electrode of the capacitor, and a predetermined voltage is thereby held in the capacitor.
