The Samsung LED DLP Television
Samsung Solves the Rainbow Effect
While most of the new TVs presented at the Consumer Electronics Show in Vegas were focused on making TVs as thin as possible, Samsung moved in a different direction. Samsung may have perfected the DLP TV.
Samsung has more years of experience producing DLP based TV’s than most of their immediate competitors. Therefore, it stands to reason that Samsung developed an innovative system that has made the DLP rainbow effect a thing of the past.
The Samsung 56" HL-S5679W is the latest DLP model offered by Samsung. This model was presented at CES, 2006 (Consumer Electronics Show) in Las Vegas. Using Texas Instruments' DLP DMD (digital mirror device) technology, the HL-S5679W is the first television to think outside the color wheel.
Samsung has overcome the color wheel by replacing it with a network of LED lighting. The LED lighting is comprised of a stationary red, green, and blue color schema. The LED's provide a separate light source for each pixel, which gives the new LED-DLP displays a contrast and brightness that rivals Plasma. However, unlike Plasma technology, this system has no chance of burning in. Using LEDs also allows this rear projection model to dispense of the need for lamps and expensive bulb replacements. Samsung claims their new LEDs will last an astonishing 20,000 hours of operation. This projected time horizon is approximately three times longer than the average life of a bulb.
The new HL-S5679W model will be compatible with 1080P. Many of the early iterations of 1080P did not provide the televisions with a connection capable of providing the display with 1080P /60 frames per second images. Samsung itself was guilty of this. Consumers no longer need to worry. According to Samsung, this set will be fully 1080P input ready. This means that the HL-S5679W will be compatible with your next gen storage devices, such as Blu-Ray and PS3.
What is the Rainbow Effect?
Every display device has a technological limitation, which prevents many televisions from being the ultimate TV. For DLP the drawback has always been the rainbow effect. The rainbow effect occurs whenever you see a rainbow in the picture that isn’t meant to be there. The rainbow usually follows a fast moving on-screen object. Some viewers experience the rainbow effect more than others, but if you were to flick your eyes (field of view) across any DLP picture chances are you’ll experience the rainbow effect. The rainbow occurs because of the color wheel: the component that provides color to the light reflecting off the digital device that produces the picture in DLP.
Samsung promises the set to be available by April of 2006 for a retail price of $4000. That’s a very reasonable price for a digital rear projection TV of any kind.

The digital video realm is the arena where cable TV pulls away from satellite as the complete package. A broadband two-way communications pipeline offers benefits that satellite can only dream of- forcing the competition to provide better service cheaper, just to stay in the same league.
