Abstract:
An organic electroluminescence (OEL) matrix-type single-pixel driver, which comprises:an OEL device with an anode and a cathode; an NPN transistor with a collector, an emitter, and a base; and a PNP transistor with a collector, an emitter, and a base; wherein the collector of the NPN transistor couples to a voltage source, the emitter of the NPN transistor and the emitter of the PNP transistor couple together to the anode of the OEL device, the base of the NPN transistor and the base of the PNP transistor couple together to a data line, the cathode of the OEL device couples to a scan line, and the collector of the PNP transistor couples to a ground.
