One debate we hoped to squelch with this test was whether DLP could match LCoS on image detail. Both sets are spec'd at the 1,920 x 1,080-pixel resolution that defines a 1080p display, but they deliver the image differently. LCoS TVs use microdisplay chips that have a discrete 1,920 x 1,080-pixel grid; all the pixels on the chip appear simultaneously on the screen. DLP currently achieves 1080p resolution using a technique called "wobulation": the pixels are split between two fields flashed up in rapid succession, each with half the total pixels..Read on over here.
