Abstract

A unit pixel of a display includes a driver circuit, a memory circuit and a current controller. The driver circuit is configured to drive a light emitting device. The memory circuit is coupled to the driver circuit, and is configured to store image data for the unit pixel. The current controller circuit is coupled to the driver circuit, and configured to control a current flowing through at least a portion of the driver circuit such that the driver circuit drives the light emitting device with a constant or substantially constant current.
