  • Patent number: 11502134
    Abstract: This disclosure relates to reduced power consumption OLED displays at reduced cost for reduced information content applications, such as wearable displays. Image quality for wearable displays can be different than for high information content smart phone displays and TVs, where the wearable display has an architecture that in includes, for example, an all phosphorescent device and/or material system that may be fabricated at reduced cost. The reduced power consumption can facilitate wireless and solar charging.
