Abstract
Official abstract text for this publication.
A pixel includes five transistors and a capacitor. A first transistor controls current to be supplied to a light-emitting element. A second transistor is connected between a gate electrode of the first transistor and a first power supply. A third transistor is connected between the gate electrode of the first transistor and a second terminal of the first transistor. The capacitor is coupled between the third transistor and the second terminal of the first transistor. The fourth transistor is connected between the second terminal of the first transistor and a second power supply. The fifth transistor is connected between the second terminal of the third transistor and a signal line. The capacitor may be the only capacitor in the pixel, and the signal line may receive an initialization voltage and a gray scale data voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for driving a display apparatus, the method comprising: charging an initialization voltage in a capacitive element of a pixel circuit; charging the capacitive element with a first data voltage determined based on a gray scale data voltage and a threshold voltage of a first transistor in the pixel circuit; and supplying a light-emitting element in the pixel circuit with current, corresponding to the first data voltage charged in the capacitive el…
