LCD vs Plasma vs LED

Which is better to buy? LCD, Plasma, or LED TV? It can be a difficult decision, and one not helped by having to decide between remarkably similar features and qualities. But let us take you through some of the qualities of each that might make your choice a little easier.

Plasma technology was originally invented in monochrome in 1964. However, it has come a long way since then - developing into the key competitor in today’s flat-screen TV market. Plasma screen technology is basically many tiny cells containing gases, all cushioned between two layers of glass. These gases become plasma when electricity is applied, eventually emitting light to transmit your favourite shows and games.

LCD technology, however, involves a series of filters over a layer of liquid crystal molecules. This is contained within two glass plates. The images you see are controlled by the filters which twist when electricity is applied to allow fluorescent light through in varying degrees.

LED technology is the latest emerging technology in flat screen TVS. LED TVs are known as a much more energy efficient and compact option than LCD TVs, offering screens only 1 inch thick. In fact, LED TVs are composed of a hybrid of LCD technology, with LED backlighting instead of fluorescent backlighting, bringing brighter contrast, more powerful colours and deeper blacks. LED TV technology is also incredibly energy efficient, currently using 40% less energy than many LCD models.

Plasma screens are seen as bulkier or heavier than LCD and LED screens, though some manufacturers have introduced thinner models. LCD and LED screens are generally thinner than Plasmas, making them easy to mount on a wall. Plasmas do well in terms of contrast and ‘blackness’, in that they are more capable of producing a darker black than LCD screens. While LCD screens have made leaps and bounds with this problem, their darkest blacks do not hold up when looking at your picture from the side, or off axis. However, the technology used in LED TVs means that even the improved LCD colour is enhanced, meaning a much bigger gamut of colours and blacks in every image.

LCD and LED screens hold up in terms of glare on the screen, whereas Plasma TVs can face problems with it. However, some Plasmas are being produced with anti-glare glass installed to reduce this. Plasma screens also face a problem of image burn – if you leave a bright image paused on your monitor for a long period of time, that image will be imprinted on your TV. Though this fades with time, LCD and LED TVs face no such problem. Not only this, but LCDs are also designed to have more connectivity with PCs than Plasmas do.

Plasmas also win with response times, meaning that the image is received and broadcast slightly faster than LCDs. This makes Plasmas a good choice if your preference is high speed action, or sport.

Besides all of this, LCD, LED and Plasma screen TVs have several points in common. All are capable of delivering up to 60,000 hours of performance, or 8 hours per day for 20 years. There are many, many models available at similar prices and sizes. With many of the above mentioned problems, there are just as many models designed to combat the issues – meaning the best you can do when buying is to come to a store and check out the physical attributes of your potential purchase.
