Organic light emitting diode devices using thermostable hole-injection and hole-transport compounds |
| abstract |
The present invention relates to multi-layered organic light emitting diode devices having hole-injection and/or hole-transport layers comprising aryl amine compounds with relatively high glass transition temperatures (i.e., thermostable aryl amine compounds). Such multi-layered OLED devices allow for a staircase change in the energy difference of holes and electrons as they migrate from the electrodes toward the emitter layer, resulting in a lower operating voltage and a high quantum yield of luminescence for a given current density. The present invention also relates to microdisplay devices comprising multi-layered organic light emitting diode devices having hole-injection and/or hole-transport layers comprising thermostable aryl amine compounds. |
