Technologies transferred
•LC property measurement system : Bona Fide
•LCOS microdisplay: Himax in Taiwan
•CVA: Virtual Semiconductor in Hong Kong
•Photoalignment: DIC in Japan
•AMOLED: Sinodisplays Ltd in China
Microdisplays
Requires research in reflective display modes, modeling of LC alignment in small pixels and cross talks, integrated circuit design, projection optics design etc
HKUST has the highest number of papers published in microdisplays
Technology transferred to Himax (Taiwan)
Photoalignment
We proposed a new method of photoalignment using a rotational diffusion model, developed the materials, and examined the fundamental interaction mechanisms
Partnered with Martin Schadt, inventor of LCD and winner of the Draper Prize
Technology transferred to DIC (Japan), third largest supplier of LC materials. Photoalignment will be used in future G10 manufacturing lines

When people talk about photoalignment, they think of HKUST
Research topics
Video technologies: subpixel rendering, video coding standards, new time sequential schemes, low power circuit design
Frontier technologies: application of nanotechnology and nano-optics, flexible substrates, 3D displays, nanoimprint technology, cell phone projectors, pulsed laser deposition of new materials, liquid crystal photonics
Energy saving displays
LCD light transmittance is only 5-8%
Eliminate color filter, T becomes 25-40%
Eliminate absorptive polarizers, T increases to 50-80%
Cell phones and Laptops that last for weeks? TVs that can run on a few batteries?
Required technology: fast LCD, fast signal processing and fast TFT driving, reflective polarizers

Many interesting switchable photonic devices such as LC filled optical fibers and waveguides, photonic crystals, optical vortices, diffractive waveplates, variable focal length lens
Tunable LC lens array can be used for 3D displays (integral imaging)
Impact
• Impact on Fundamental Research:- The collaboration will be an excellent
platform for a very strong team of top-notch researchers to strive for
fundamental breakthroughs to redefine future information green display and
photonics systems and to achieve international reputation as a global leader
in display and photonics design.
• Impact on Innovation and Entrepreneurship:- In addition to theoretical
breakthroughs, the collaboration will also strive to drive the future display and
photonics technology through test bed development, technology transfer with
key industrial players locally and globally, technology startup as well as
standardization in future display and photonics systems. The collaboration
will cover a broad range of inter-disciplinary technologies, which naturally
serves as an entry barrier to potential competitors.
• Impact on Education and Training:- Furthermore, the proposed
collaboration will strive to be a global training for green display and
photonics technology. Researchers and faculty members can acquire
various display core technologies through participation in research
programs, collaborative research and internship with industrial partners in
Mainland China, as well as international workshops and training courses.
• Impact on Attracting Funding:- The proposed collaboration will also be an
excellent platform for attracting Mainland government funding. In Mainland
China, display research area is one of their core foci in the next 5 – 10
years and a lot of funding investment will be set aside to support R&D in the
area. In particular, strong preference is given to the team with good
theoretical research as well as implementation capabilities and the center
will be well-suited to leverage on these huge funding.
Impact
Collaboration with Russia The experience of 15 years collaboration with various Russian
Universities will be described. Our Russian partners includes: Skolkovo Institute of Science and Technology (Skoltech),
Moscow State University,
Moscow State University of Instrument Engineering & Computer Science, Moscow Region State University,
Shubnikov’s Institute of Crystallography, Russian Academy of Sciences, Moscow,
Russian Research Institute of Cosmos Instrument Engineering, Moscow, St.-Petersburg University of Information Technologies, Mechanics and Optics,
Irkutsk State Technical University.
The author has a long term collaboration with these Institutes and Research Centers, including a variety of joint publications, patents, Conference presentation and even books.
Green displays and photonics technology will definitely benefit Russian Companies such as Oil and Gas Companies ( Gazprom, TNK-BP, Lukoil); Materials and Construction Companies (Russian Railways, Highways and Helicopters); and definitely IT Companies (Rostelekom, Microsoft Rus, IBS etc).
