This book highlights the display applications of c-axis aligned crystalline indium–gallium–zinc oxide (CAAC-IGZO), a new class of oxide material that challenges the dominance of silicon in the field of thin film semiconductor devices. It is an enabler for displays with high resolution and low power consumption, as well as high-productivity manufacturing. The applications of CAAC-IGZO focus on liquid crystal displays (LCDs) with extremely low power consumption for mobile applications, and high-resolution and flexible organic light-emitting diode (OLED) displays, and present a large number of prototypes developed at the Semiconductor Energy Laboratory. In particular, the description of LCDs includes how CAAC-IGZO enables LCDs with extremely low refresh rate that provides ultra-low power consumption in a wide range of use cases. Moreover, this book also offers the latest data of IGZO. The IGZO has recently achieved a mobility of 65.5 cm2ƒ}V-s, and it is expected to potentially exceed 100 cm2ƒ}V-s as high as that of LTPS. A further two books in the series will describe the fundamentals of CAAC-IGZO, and the application to LSI devices. Key features: • Introduces different oxide semiconductor field-effect transistor designs and their impact on the reliability and performance of LCDs and OLED displays, both in pixel and panel-integrated driving circuits. • Reviews fundamentals and presents device architectures for high-performance and flexible OLED displays, their circuit designs, and oxide semiconductors as an enabling technology. • Explains how oxide semiconductor thin-film transistors drastically can improve resolution and lower power consumption of LCDs.

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.
