Non-ITO transparent electrode Home ⇒ Technology ⇒ Non-ITO
transparent electrode Although ITO (Indium Tin Oxide) is the most
common transparent electrode, it is well known that ITO contains issues in
cost because Indium is a rare metal and the fabrication processes of ITO
layer on substrates are expensive due to the vacuum and photolithography
processes. Based on
such background, various non-ITO transparent electrode technologies have been
developed. We have developed several novel non-ITO
transparent electrode technologies shown below. ◆ Non-ITO Transparent
Electrode with Implanted Metal-mesh Structure (2020, 2021) The conducting polymers for an anode of
OLED devise were developed. OLED devices
with the developed conducting polymer show comparable performance with the
reference OLED devices with normal ITO.
ITO-free OLED devices were developed using the developed conducting
polymer and an assisting bass line [1]. ◆ Non-ITO transparent
electrode fabricated by printing technologies （2017） ◆ Stacking electrode consisting of silver nanowire
and conducting polymer The stacking electrode consisting of
silver nanowire and conducting polymer was developed. Flexible OLED devices on ultra-thin
glass were developed using the stacking electrode consisting of silver nanowire and
conducting polymer. References [1]
