Abstract
A pixel circuit for a light emitting display. Adjacent pixels of the light emitting display coupled to one scan line share one first power supply line. A driving circuit in each pixel circuit drives first and second organic light emitting diodes (OLEDs). A switching circuit is coupled between the first and second OLEDs and the driving circuit to sequentially control the driving of the first and second OLEDs. Because two adjacent pixel circuits share one pixel power supply line and a plurality of OLEDs are coupled to one pixel circuit, it is possible to reduce the number of pixel circuits and the number of wiring lines of the light emitting display. Other circuit elements may also be shared between adjacent pixel circuits. Reducing the wiring and other elements of the pixel circuits makes it possible to increase the aperture ratio of the light emitting display.
