DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME

摘要

Pixel circuits of a display device each include: a drive transistor including one of a source and drain connected to a power source line; a capacitive element including a first terminal connected to a gate of the drive transistor; a switching element which switches conduction/non-conduction between a second terminal of the capacitive element and a data line; a switching element which switches conduction/non-conduction between the second terminal of the capacitive element and the source of the drive transistor; a switching element which switches conduction/non-conduction between the first terminal of the capacitive element and a reference voltage line; a light-emitting element including a first terminal connected to the other of the source and drain of the drive transistor and a second terminal connected to another power source line. The reference voltage line provides a forward bias voltage larger than a threshold voltage across the gate and source of the drive transistor.
