Challenges and Opportunities of IGZO Panels

Challenges and Opportunities of IGZO Panels

IGZO (Indium Gallium Zinc Oxide) TFT (Thin Film Transistor) panel, hereinafter as IGZO panel, has potential advantages over a-Si (Amorphous Silicon) and LTPS (Low Temperature Polycrystalline Silicon) ones, including high resolution, low power consumption, transparency and higher suitability for large area processes. IGZO TFT panels can be used in smartphones, 2-in-1 tablets, wearables, TVs, and digital signage. Despite possessing the solution to meet market needs, however, its market penetration remains low three years after Sharp produced the first IGZO panel in 2012. This report takes an in-depth look of characteristics of IGZO panels and discusses the challenges and opportunities facing in the development of IGZO panels.
