Future smart phones will project images on the wall

29.02.2012
New laser light source has a global market in consumer electronics
Mobile phones currently on the market are capable of showing high quality images and video, but the phones' small size sets insurmountable limits on screen size, and thus the viewing experience. VTT Technical Research Centre of Finland, EpiCrystals Oy and the Aalto University are developing a better laser light source for projectors that will be integrated into mobile phones, which will enable accurate and efficient projection of, for example, photographs and movies on any surface. Mobile phones equipped with the laser light source can be within the ordinary consumer's reach already in a few years time.

Small-size laser projectors 1-2 centimetres in length can be integrated into many kinds of electronic appliances, such as digital or video cameras, gaming devices and mobile phones. Integrated micro projectors could, in practice, project images the size of an A3 sheet of paper on a wall.

The challenge is to develop a small, energy-efficient and luminous three-colour (RGB) light source, whose manufacturing costs can be kept low, for use in the projectors. Solutions for these challenges are sought in a project combining Finnish know-how, whose parties are VTT, EpiCrystals Inc. and the Aalto University.

"The project has successfully combined multi-technological know-how from VTT and its partners in the project, from manufacturing materials and the accurate focusing of laser chips all the way to production line design. The project was launched last autumn, and we are now entering the stage where we can move from brainstorming and design to building prototypes. It is our goal to prove by next summer that large quantities of the new laser light sources can be manufactured quickly and economically ", says Principal Scientist Timo Aalto from VTT.

EpiCrystals Inc. aims straight for the global market with its product, and it is the company's goal to be the technology and market leader in laser light sources for micro projectors by 2015.

"We are developing an entirely new technology that is currently not in use anywhere else in the world. At the moment, there are stand-alone projectors on the market that can be connected to electronic appliances and early stage integrated projectors, but their quality and price are not competitive enough. Large electronics manufacturers are extremely interested in integrated projectors, and market research shows that demand for these micro projectors will increase strongly in the coming years. Soon, around two billion mobile phones per year will be sold in the world, and if even a couple of per cent of those contain a projector, we are talking about tens of millions of copies, and the hundred million mark is not far either", says Vice President of Business Development Tomi Jouhti of EpiCrystals Oy.

EpiCrystals’ laser modules will be mass-produced in Asia, but the research and development will remain in Finland also in the future. The VTT, EpiCrystals and Aalto University project has received funding from the Finnish Funding Agency for Technology and Innovation Tekes, among others.

EpiCrystals Inc. develops innovative laser light sources for next-generation projectors. The products patented by the company enable the manufacturing of more economical and compact projectors with superior image quality. EpiCrystals employs 24 people and its product development has been funded by Tekes and investment funds managed by VNT Management Oy and Suomen Teollisuussijoitus Oy (Finnish Industry Investment Ltd), among others.

Im Focus: New studies increase confidence in NASA's measure of Earth's temperature

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...

Im Focus: The geometry of an electron determined for the first time

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.

The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

Im Focus: Quantum Cloud Computing with Self-Check

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...

Im Focus: Accelerating quantum technologies with materials processing at the atomic scale

'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.

However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
