'Lamp-free' home projector
At today's ongoing InfoComm expo, Texas Instruments is demonstrating a new projector technology (not pictured) which it claims will significantly improve home theater setups. Combining a PhlatLight LED with a BrilliantColor chipset, the TI arrangement completely omits a lamp, instead relying on mirrors and the LED itself to provide enough light. The major advantage is said to be a lack of lamp replacements and filter changes, which can potentially be expensive for home viewers.
Other advantages should include a 50 percent larger color gamut, reaching 200 trillion shades, and a 30 percent lower power consumption. Despite this it should achieve an extremely high 500,000:1 contrast ratio, maintaining 1080p resolution. The first lamp-free LED projectors should ship in "late 2008" from companies such as Optoma.
