E Ink and Sharp Collaborate on Oxide Backplanes for Next-Gen ePaper

E Ink Holdings Inc, a pioneer and global leader in digital paper technology, and Sharp Display Technology Corporation (SDTC), a leading display company, announced its collaboration and adopted SDTC’s Indium Gallium Zinc Oxide (IGZO*2)*1 backplanes for ePaper modules used in eReader products and eNote.
E Ink has been developing the use of oxide thin film transistors (TFTs) for electrophoretic technology for over a decade and will expand its ePaper product portfolio based on the use of oxide TFTs. Sharp was the first to mass-produce oxide TFTs for displays in 2012. Oxide TFTs have high mobility (a measure of how easily an electron moves through a particular material) and low leakage current in transistors, allowing the use of smaller transistors. supply the same current. In a display, this means faster switching speed is possible and lower power consumption, contributing to a sustainable environment. E Ink and SDTC have been working together for two years to bring oxide TFTs to market for ePaper displays.

“Joining forces with SDTC once again demonstrates E Ink’s commitment to improving ePaper display performance,” said Johnson Lee, CEO of E Ink. “TDDC’s vision is to develop oxide TFT technology that can serve different types of displays and circuits, and TDDC is committed to continuing to invest in the development of oxide TFTs. E Ink welcomes our partnership with SDTC.

“SDTC is delighted that E Ink has chosen SDTC as their oxide TFT partner to bring the next generation of ePaper displays to market,” said Chien-Erh Wang, President of SDTC. “SDTC is the market leader and pioneer in the research and development of oxide TFTs, and is also the first display company to mass-produce oxide TFTs. E Ink is the market leader in ePaper displays, and merging these two companies is a natural progression.”

Over the past five years, 130 million e-readers have been used worldwide, replacing the purchase of paper editions of books. It is estimated that paper books would emit more than 100,000 times more CO2 than e-readers would have contributed significantly to the reduction of CO2 emissions throughout this period. Moving color content to e-readers would have a significant impact on the environment.

Going forward, E Ink and SDTC will explore the use of IGZO for larger sizes for retail and transportation signage applications. In addition, Sharp Group will also consider collaboration models with E Ink for various ePaper applications.

The next generation of ePaper based on the collaboration of this era is expected to be exhibited at CEATEC 2022, which will be held at the Makuhari Messe Convention Center (Mihama-ku, Chiba, Japan) from October 18 to 21 (Tuesday to Friday) from this year.
