Quick Question.
I know QMC shipped samples of both metallic oxide and Quantum dots to display industry. Is metal oxide/TFTs complementary or competitor to QDots? seems like it is overlapping with QD in display and energy storage and looks as promising as QDots. Moreover unlike QD it has a place in OLED technology too.
Metal Oxide TFT Backplanes For Displays:
Metal oxide display backplanes have already gone commercial. Sharp has invested in establishing a Gen8 IGZO plant at its Kameyama plant in Japan while LG has also selected IGZO backplanes for its large-sized white OLED technology. At the same time, Chinese companies such as BOE are fast playing catch up with both prototype and production capacity announcements.
IDTechEx estimates that 7 km sqr of metal oxide backplanes will be used in the OLED industry in 2024, enabling a 16 billion USD market at the display module level. The LCD display market will add an extra demand of at least 1 km sqr per year in 2024 for metal oxide backplanes.
It is within this emerging within this complex yet changing space that metal oxide are emerging. They promise low leakage currents, high mobility, amorphousity, stability and wide bandgap. These attributes promise to enable, respectively, power consumption reduction, compatibility with current-driven OLEDs and/or 3D displays, image uniformity over large areas, long lifetime and transparency.
In the short term, this will help enable higher resolution and lower power consumption levels in displays including LCDs (particularly in medium- to large-sized displays); while in the medium- to long-term metal oxides will help enable uniform medium- to large-sized OLED displays.
