Abstract
A display device that includes multiple pixels, each pixel includes a light emitting element, a multiple of transistors, multiple voltage sources and capacitors. The pixel circuit is designed and the pixels are driven so that a driving current going through the light emitting element is independent of a threshold voltage of a driving transistor of the multiple transistors. As a result, luminance variation due to threshold voltage can be minimized, and residual image can be reduced.
