The Lurks and Perks of LED TVs
There’s a reason that there is little difference in the name between LCD televisions and their LED counterparts – because the technology has the same basis, although the LED version is more refined. LED televisions are made in almost the same way as LCDs, just with a different lighting technique that produces energy savings, improved contrast ratio and an ultra-thin profile.
How do LED televisions work?
To understand LED technology, it is easiest to first understand how ordinary LCD televisions work. An LCD television is made of two sheets of polarising plastic filters, sandwiching a film of liquid crystals. When voltage is applied to a crystal, it turns on an angle; this effectively switches off the pixel, as light cannot pass through it. Red, blue and green filters and a light behind the panel create brightness and a range of colours.
The Lurks and Perks of Plasma TVs
Plasma is a very well-known, although fortunately little-bought, television technology. There are some wonderful models out there, that have drool-worthy resolution, colour saturation and contrast ratio stats. If you also enjoy owning expensive items for the sake of it, plasma televisions have a much higher ‘friend-envy’ factor. However, unless you buy top-of-the-line models, there are quite a lot of technological issues to be found in plasma televisions. We look at when the model is preferable to LCD televisions, like favourite Samsung TVs and other big brands, and when LCD wins out.
The Lurks and Perks of LCD TVs
LCD televisions, despite having a display type with inherent scientific difficulties, have risen to become the market leader in the multimedia world. Buying televisions always engenders a debate about whether ‘to LCD, or not to LCD … that is the question’! Today we are exploring exactly what makes LCD televisions ‘tick’, and whether the display technology will be the right one for your viewing preferences.
