Grating Light Valve (GLV) is a technology that works on the principal of dynamic adjustable diffration grating. Pixels are created from ribbon like structures on a silicon wafer. These structures are held under tension over a thin air gap and are allowed to move vertically. Deflection of the ribbons causes diffraction of incident light and controlling the ratio of diffraction to reflection is what makes GLV suitable for applications such as imaging, displays and projection. GLV was first discovered at Stanford University in California. The inventors named the company Silicon Light Machines to further develop and commercialize the technology. This company was later bought by Dainippon Screen Manufacturing Co., Ltd. and now is a wholly owned by the latter.
This technology has several unique performance advantages as compared to spatial light modulator technologies and these include rapid swithcing speeds, ability to withstand high opticcal power densities, among others. Such features can be leveraged for developing advanced projection display architectures that turn out to be more cost effective that conventional projection display systems that are currently available in the market. GLV is poised to be the latest solution for the imaging industry that offers high quality display systems.
There is a considerable amount of research and development currently underway at Universities, Research Institutes and Company R&D facilities across the globe and this could potentially further augment the GLV Display Technology market. High initial costs that are typically associated with new and upcoming technologies are expected to initially hinder the growth of this market.
Automotive displays constitute the fastest growing segment for the GLV display technology owing to the benefits the technology offers coupled with the suitability for automotive application requirements.
In terms of applications, the GLV Display Technology market has been segmented across the following:
- Head-up Displays
- Automotive Displays
North America and Europe currently hold the top positions in this market and will continue to do so till the end of the forecast period considered in this report. Given how niche the technology currently is, it will take a few years for mass commercialization of products. Once that happens, the growth opportunities for GLV display technology are limitless.
The market has been segmented based on the following geographies:
- North America
- South America
- Middle East
Following are just a few of the companies that are operating in the GLV Display Technology market:
- Dainippon Screen Manufacturing Co., Ltd
- Sony Corporation
