GUANGZHOU, China, Feb. 7, 2018 /PRNewswire/ -- One of the world's
leading research centers in electronic paper displays, the
Electronic Paper Display Institute (EPDI) at South China Normal
University in Guangzhou, founded
and led by Professor Guofu Zhou, in
conjunction with Shenzhen Guohua Optoelectronics Ltd. and GR8
Optoelectronics Ltd as industrial partners, is in a continuing
search for the best possible e-paper solutions. Recently, its
activity relating to research, development and industrialization of
electrowetting / electro-fluidic displays has reached several
breakthroughs in these fields and will accelerate the
development to full maturity of the technology and take this
development to the market.
The breakthroughs that were achieved in the development
phase comprise the achievement of an unparalleled
switching speed in an electrowetting display: both switch-on and
switch-off times were reliably below 3 ms, which is faster than
typical LCD. Also, robustness of the display was assured by a
successful implementation of a proprietary spacer-ing method. Finally, significant
steps were made towards operating the display at voltages similar
to LCD and power levels (typically 100 nW/cm squared)
significantly below those of LCD.
According to Professor Zhou, these breakthroughs will lead to
wearable devices with large displays, without the necessity of
frequent charging. "We will finally see a digital watch with an
always-on display," he said.
The team has already shown good results in colorful active
matrix displays, as single- or multi-color devices, with excellent brightness
and contrast. They expect to be able to finalize the developments
during the next 6 months and start shipping samples to interested
customers this summer.
According to Professor Alex
Henzen, team director of the EPDI team and technical leader
on e-paper, the team is ready to make the next step in the
development cycle and will begin industrialization on the Gen 2.5
prototype line. The line is set up to be capable of producing
30,000 substrates of 400 x 500 mm per month.
The Institute of Electronic Paper Displays at South China
Academy of Advanced Optoelectronics of South China Normal
University was founded in 2012 by a group of original core members
of the Philips e-paper display research and development team. The
Institute mainly focuses on the research, development and
industrialization of green optoelectronic technologies,
particularly electronic paper displays with color and video
capability as major challenges. Since the grant of National
Research and Development Program of China (No.2016YFB0401500), the institute,
jointly with 12 other institutes, has sped up
innovation and made significant progress in the past year. More
than 100 patents have been created so far and new products are
developed through cooperation with the startup company of the team
and SCNU.
