Innovating is never easy. Most rear-projection televisions (RPTVs) that use Texas Instruments' Digital Light Processor (DLP) are single-chip designs that generate color through the use of a spinning color wheel. The problem is that these wheels can generate mechanical noise and even cause some viewers to perceive a distracting rainbow artifact. To address these drawbacks, Samsung's 56-inch Samsung HL-S5679W forgoes the color wheel and the projection lamp in favor of an array of sequentially fired red, green, and blue light-emitting diodes. Samsung claims that these LEDs will last more than of 20,000 hours and improve color reproduction. Now, I have no doubts about the longevity of LEDs or their ability to produce well-saturated and pure colors. But the color accuracy of the HL-S5679W's picture, however, had room for improvement, and if you need a bright picture for a well-lit room, this is definitely not the TV for you.
