UNDERSTAND OLED DEVICE PHYSICS FROM CARRIER INJECTION TO LIGHT EMISSION Physics and Technology of Organic Light-Emitting Diodes presents the first textbook focused solely on OLEDs built from amorphous organic semiconductors. Two veteran researchers with decades of combined expertise detail device operation mechanisms, from carrier injection through light emission, emphasizing the structure and behavior of multilayer thin-film OLEDs that power modern smartphones, televisions, and AR/VR displays. This book combines the latest theoretical and experimental research with rigorous analysis and practical applications, examining exciplexes, tandem OLED devices, carrier pair generation, and molecular orientation effects. Readers explore degradation mechanisms and device lifetime from a physical perspective, along with ultra-stable glass formation via vacuum deposition. Numerical examples and illustrations throughout support deeper understanding of these concepts. Readers will also explore: Theoretical foundations paired with practical data connecting academic research to industrial OLED development and manufacturing requirementsDevice operation mechanisms specific to amorphous glass organic semiconductors aligned with current technological mainstream applicationsPhysical analysis of degradation pathways and device lifetime factors critical for improving OLED reliability and performanceTandem OLED architectures and carrier pair generation concepts essential for next-generation high-efficiency display designsVacuum deposition techniques for ultra-stable glass formation enabling superior thin-film quality and device characteristicsEngineers and lab scientists working in OLED development will find authoritative guidance on device physics principles. Graduate students in materials science, applied physics, or electrical engineering gain focused instruction on amorphous organic semiconductor behavior directly applicable to display technology research and development.
