Abstract:
A multiple emitter organic light emitting diode (OLED) is provided. The OLED comprises a host having a triplet energy gap. At least one emitter having a triplet energy gap greater than the triplet energy gap of the host is doped into the host and at least one other emitter having a triplet energy gap less than the triplet energy gap of the host is also doped into the host.
