LED TV vs. LCD TV Vs Plasma TV

LED TV vs. LCD TV Vs Plasma TV Era TV tubes are decades into electronic devices to bring a favorite family entertainment program coming to an end in the foreseeable future. New digital broadcast standard that is currently already under trial in the capital and will follow other cities in the near future seems to trigger the acceleration of the shift to digital TV using devices such as Plasma TVs, LCD TVs, LED TVs and latest technology. In addition, the various advantages offered also catapulted the popularity of flat-screen TVs of all three types of technology, among other things: the size of a thin, lightweight, and can be hung on the wall. Large screen size is also the main attraction for fans of television tanyangan. Do not miss all the energy-saving features offered, which allows saving electricity consumption. Buying a Digital Television, it seems quite difficult for most people, because of the emergence of new, confusing terminology, which is often the same technology gets different labels among different manufacturers. One of the most confusing is the difference between Plasma TV, LCD TV and LED TV. Countless times use the designation "Plasma TV" is directed to a LCD TV, Plasma recall is one of the first technologies for flat screen with a large size (> 42 "). What exactly is the difference between the three types of the flat screen TV? Which of the three types of TV is that worth to buy? Here are descriptions and differences Plasma, LCD TV, LED TV and. • Plasma TV Plasma Display Panel (PDP) or in Indonesia widely known as the Plasma TV is a type of flat screen TV technology that allows manufacturers to produce big size Flat Screen TVs in bulk at an economical price. The term and concept of technology itself Plasma TVs introduced in 1936 by an expert in Physics, Electronics, and inventor of Hungary [1]. In the development of IBM, Fujitsu, and Panasonic introduce some type of television that utilizes plasma technology in their research. New in 1997, followed by Philips and Pioneer Fujitsu, released flat-screen TV with a 42 inch Plasma technology is commercially [2]. The term itself comes from the use of PDP Plasma cells, which is a fluorescent lamp, as the basis for the television screen lighting. A Plasma TV Plasma cells make use of the millions who placed between two panes of glass screen. Each cell contains a combination of noble gases and a small amount of mercury to be evaporated and given power to glow and form a plasma. Color produced from phosphorus contained in the cells, where each cell in the phosphorus will contain three types of primary colors, namely: Red, Green, and Blue, or commonly known as RGB. Difference voltage assigned to each cell also produce color combinations that exist. Advantages Plasma TVs • Produces black better than LCD TV • Contrast ratio is high (1:2.000.000) • wider viewing angle more • Refresh Rate and Response Time is fast, minimizing image blur Weakness Plasma TV • The still image is displayed for a long time will cause burn-in and image ghosting • The image quality will continue to decline as the duration of use, although in a relatively long period of time • Heavier than LCD • Using a power greater than the LCD TV • Size is generally not available below 42 inches. • LCD TV LCD TVs on the market which appear first of Plasma experienced a decline in popularity since the emergence of Plasma TVs considering the various advantages offered compared to earlier generation LCDs. With a price that is much more expensive for a smaller size, making Plasma sales increased. However, on further developments, LCD TV with economical price with many technical advances, making consumers switch back to LCD TV. Along with the emergence of HDTV and Full HD TV LCD TV product in the line, followed by a large measure, the price of LCD TVs was also increasingly makes sense in the pockets of consumers. Basically LCD TVs work by producing a black and colored image by selecting a series of light emitted by the lamp technologies CCFLs (Cold Cathode Fluorescent Lamps) behind the scenes. Millions of lights will be switched on and off through the LCD shutter by passing white light with a certain intensity. Each shutter will be combined with color filters will miss the colors Red, Green, and Blue (RGB). Shutter and Filter, each of which is a sub-pixel size is very small, and the tangible form the joint called denganpixel [3]. LCD TV excellence • Produce more realistic colors • Technology anti glare (without shadows) • Available from sizes small to large • There is no radiation emitted • Can be used as a computer monitor • The need for a power source that is lower than the Plasma Weakness LCD TV • The picture quality will decline when seen at a wide angle • For the bigger, more expensive when compared to Plasma TVs • Refresh Rate and Response Time, which is much lower than plasma, so that sometimes produces a blurry picture • LED TV In recent years, the digital television market enlivened by the presence of a flat-screen television technology by several leading electronic vendor called LED TVs. The most aggressive vendors in TV poured with this new technology include: Samsung Electronics, LG Electronics, Toshiba, and many other leading vendors. Basically LED TV is actually an LCD TV where the development of this type uses LED backlight instead of the fluorescent light used in the previous type of LCD TV. There are two kinds of LED TVs on the market: RGB LED with LEDs placed behind the display panel, or EDGE-LEDs where the LEDs placed around the screen [5]. Excess LED TV • The level is much higher contrast than LCD TVs, equal to or even higher than Plasma TVs • Enables manufacturers to produce flat-panel televisions with super slim size, with a thickness of about 2.5 cm • More environmentally friendly • Electricity consumption is about 20-30% lower than conventional LCD TVs • Various LED TV products from well known vendors offering digital image processing features, features Digital TV Tuner, and various other new features. Weakness LED TV • The price is more expensive, at this time for the same size, the price of the cheapest LED TV about 1.5 times conventional LCD TVs • [UPDATED Oct. 17, 2011]: Prices are a little more expensive, for the same size and features, the price of the cheapest LED TV around 20% more expensive than conventional LCD TVs Conclusion In general, LED TV offers better picture quality when compared with LCD TVs, especially to contrast images as well as black perfection,, although for most people the difference is not too noticeable. This is because the quality of the LCD TV which is sufficient. When compared with plasma, also offered quality level or even more, given the latest LED TV offers several additional features for image processing. The price difference is quite striking with LCD TV, did not deter some people to buy a LED TV, LED TV appearance since a thinner and with the latest designs. For some other people who put prices on a variety of criteria for the purchase of TV, LCD TV seems to still be the main choice. Plasma itself, appears to have no interest too, and began to be abandoned since 2007, considering the price difference between who is getting thin LCD TV and Plasma TV. Design that also looks increasingly obsolete also discourage people who would buy a Plasma TV. Panasonic as one of the producers over the years by producing Plasma TV staunchly for sizes 42 inches and above, lately has begun to divert the ranks of his latest TV technology with LCD TV and LED TV. Finally, everything is up again to prospective buyers. If the available budget is sufficient, the selection of LED TVs seem quite appropriate, given the LED TV has been prepared for the digital TV technology will completely replace analogue TV in 2018. However, if the budget is limited, the LCD TV is the most fitting choice, considering the features provided is sufficient, lighter, and more energy efficient when compared to Plasma TVs.
