Speaking of CE roadmaps, here’s something that you DLP fans may be interested in. The term Unishape (Universal Shaped Lamp Light Technology) may not mean much today but upcoming DLP products that take advantage of the technology, promise reduced video artifacts and dithering, diminished rainbow effects, higher resolution in low-light scenes, brighter images in general, higher color accuracy, and improved contrast ratios. That’s quite a laundry-list of improvements. The tech behind those improvements represents a sizeable leap forward from today’s DLP projection systems.
The company behind the technology (OSRAM) goes as far as claiming up to 40% brighter images, 60% less dithering noise, up to 80% better color saturation, and up to 100% higher contrast ratios as compared with conventional DLP projection systems. Instead of going the auto-iris route, that’s been all the rage with LCD and LCoS projectors of late, the Unishape system addresses the problem at its source, the projection lamp itself.
The Unishape system consists of a matched lamp and DLP DMD paired by a custom lamp driver. Technical jargon aside, the end result is an optic system that can adjust the lamps waveform pattern in milliseconds, thereby effectively mimicking the benefits of an auto-iris (improved contrast, brightness and low level detail) at the source without the inherent lag associated with a mechanical aperture.
A few companies are already experimenting with the OSRAM Unishape system and I expect we’ll hear more about the technology at this years CEDIA in Denver, or perhaps sooner. This stands the chance to drastically change the DLP landscape as we know it and serves as proof positive that DLP won’t take a back seat to the LCD and LCoS advancement of late. P.S. take a look at the PDF linked at the end of the Unishape primer for a more technical breakdown on the system.
