OLED efficiency concepts

OLED efficiency refers to how well the display converts electrical energy into visible light. Key concepts include luminous efficacy, which measures brightness per unit of power used, and external quantum efficiency, indicating how effectively electrons generate photons. Variations in material quality, device design, and color production impact efficiency; for example, blue OLEDs tend to be less efficient than red or green ones. Higher efficiency means brighter screens with less power consumption, extending device battery life. Advances aim to improve material performance and reduce energy waste, making OLED displays more sustainable, longer-lasting, and cost-effective while delivering vivid images.
