Abstract
A delta pixel circuit and a light emitting display are able to minimize a color separation phenomenon by adjusting an emitting point of a plurality of emitting diodes (or devices), reduce the number of driving circuits, and have a high aperture ratio. A first, second, and third light emitting diodes are arranged in a delta pattern and respectively correspond to a red color, a green color, and a blue color. A driving circuit is commonly connected with the first, second, and third light emitting diodes and is for supplying a current to each of the diodes. A switching circuit is connected between the driving circuit and the first, second, and third light emitting diodes and selectively supplies the current to the first, second, and third light emitting diodes.
