Abstract
Official abstract text for this publication.
A method of driving a pixel circuit is provided. The pixel circuit includes a light emitting element that emits light by receiving a driving current, a driving transistor that generates the driving current, and a light-emission control transistor of the same conductivity type as that of the driving transistor, the light-emission control transistor being arranged on a path through which the driving current flows from the driving transistor to the light emitting element. The method includes setting the gate potential of the light-emission control transistor so that the light-emission control transistor is turned on in the saturation region for a light emitting period during which the light emitting element is allowed to emit light.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of driving a light emitting device including a first power supply line, a second power supply line, a first transistor that is P-channel type, a driving transistor that controls a driving current flowing between the first power supply line and the first transistor and that is P-channel type, a light emitting element having a first electrode coupled to the first transistor and a second electrode coupled to the second power supply line, a capacitor ha…
