Abstract
A light emitting display includes a plurality of light emitting diodes within a pixel. A drive circuit is coupled to the plurality of light emitting diodes and generates a drive current flowing through the light emitting diodes corresponding to a data current. A switch circuit assembly is coupled to the plurality of light emitting diodes and the drive circuit and sequentially transfers the drive current from the drive circuit to the plurality of light emitting diodes. The light emitting diodes sequentially emit light. When all the light emitting diodes emit light, one frame is formed.
