FullHD 120 hz projectors finally on their way?
Texas Instruments Incorporated now have a reference design published with design documents, it shouldn't take long: http://www.ti.com/tool/tida-01474 -however :) they mention one of their aim is simulation markets. Yet , with a single chip design I don't see how that would work. I think defeating sample/hold blur will take at least another generation , because their "scrolling color" reference design is still absent. Scrolling color in theory not only makes possible to have all three colors on the screen at once , but if they have silvery reflective strips besides the color strips , that would result in a rolling shutter effect. ~55% blanking coming with shutterglasses, and another ~20% coming out of rolling shutter would be ~25% duty cycle , ~ 4 ms illumination time , would be a truly safe bet for simulation market. Guess they won't make Christie Accuframe™ obsolete just yet. Without scrolling color they'd have to pulse the lasers / LEDs at extreme currents , to arrive at the same lumen output , it's a safe bet that won't happen. "Sort of" amazing they are referencing laser TV application without solving color break-up really, yet "scrolling color" as a solution was present since early 2000's . [quote="D. Scott Dewald et al."]Scrolling color has long been a goal of the projector industry, as it enables the most efficient use of light in a single panel display. Current methods of implementing scrolling color use the techniques of splitting the light into primary colors, and manipulating that light on the modulator. The authors present the techniques of dynamic filtering and sequential color recapture (SCR) to achieve the same result with no moving components other than a color wheel, showing that the efficiency of 3-modulator systems can be approached with one modulator. Analysis of the technique applied to DLP™ projection displays, and results of prototype projection systems using the techniques, will be presented.[/quote] http://onlinelibrary.wiley.com/doi/10.1889/1.1831745/abstract
