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.
