LED TVs

I started the LH90 series with the LG 55LH90 LED TV (the 55 inch version), and today we pick up with the 42 inch version, the 27LH90.  Aside from screen size, the 42 inch has exactly the same stats as the 55 inch version.   Vital Stats Screen size - 42 in Depth - 4.2 in Contrast ratio - 2,000,000:1 240 hz Price range: $2,527.00 - $3,899.95 Response time - 2.4ms Local Dimming - Yes What do these Stats Mean? The 47LH90 features "TruMotion", which refreshes the image at 240 frames per second (240 hz), which eliminates motion blur and image judder; two major problems previously associated with LED TVs. The local dimming feature ensures that the dark parts of the picture are dark, while light parts ...

LED technology was first used as status and indicator lamps. Over the past six years though, it has been developed to meet general lighting application demands. Samsung is among the first to incorporate light-emitting diodes (LED) into television technology, which is now taking the technological world by storm. With the introduction of Samsung's LED Full HD television sets B7000 and B6000, light-emitting diodes replace the obsolete CCFL or cold cathode fluorescent lamps as the main light source. As a result, extremely high contrast and slimmer depths introduce a more pleasurable viewing experience. Samsung's LED technologies TVs are also more environmental friendly as they allow homes to save more energy. Unlike other backlight technologies, LED ...

Flat panel display televisions are gaining popularity these days as they improve visibility and reduce glare due to reflection of external light. These televisions are encompasses a growing number of technologies enabling video displays that are lighter and much thinner than traditional CRT television. Flat panel display TVs can be categorised into Volatile and Static. This kind of display televisions are balance their smaller footprint and trendy modern look with high production costs and in many cases compared with traditional CRTs. The flat panel televisions are being preferred by the consumers as they minimize eye fatigue, reduce image distortion and provide a wide range of visibility. These panels have exceptional colour accuracy and ...

Light-emitting diodes (LEDs) were an accidental discovery at first. At the beginning of the 20th century, it was discovered that when electricity was applied to the semiconductor Silicon Carbide (SiC) it produced a light. This light was too dim to be of any use so the research was never distributed. This could have been the end for the LED, but it wasn't content to die out. Nearly 20 years later Russian and German scientists revisited the idea of light produced this way. The light was still of such poor luminance that the idea nearly died again. A report published in 1936, which helped to invent the term electroluminescence, revived the research for light from this source. The science ...

If you're in the market for a new television, you've probably noticed there's much more to making a selection than just knowing what size you want. Very soon however an LED TV will be the industry standard. Years ago it was as much about buying a television as a piece of furniture as it was looking at the technical specifications. Now you have to decide between plasma, LCD, projection, DLP, and on and on. If you haven't seen or heard of the newer LED TV technology, you soon will. The LED (light emitting diode) has been around for several decades now, and it's not the impressive feature in the LED TV technology. What is new is the way in ...
