LED TV Reviews
LED TVs are, in fact, just a more modern version of the LCD HDTV. Some people may be clueless about this so we’ll start our discussion with LCD technology. LCD TVs or liquid crystal display televisions use a lighting device called a cold cathode fluorescent lamps or CCFLs. These lamps are responsible for lighting up the crystals on the television screen and displaying images. The CCFLs light up LCD shutters that are on the television screen. These shutters control the amount of light that will penetrate to the screen. If the image has a bright color, then the shutters will let in large amounts of white light but if the required color is a dark one, the shutters will do the opposite. Additionally, the LCD shutters can filter specific portions of the white light to have better colors on the images.
Technology Behind LED TVs
We now discuss the technology behind LED TVs. These televisions are pretty much like the LCD televisions since they use the same liquid crystal display. The main difference between them is the lighting device. Instead of CCFLs, LED TVs use LED or light-emitting diode. These diodes are much smaller compared to CCFLs and they are placed behind the screen. This technique is called the local dimming which allows light adjustments. However, this technique can cause “blooming” or the overlap of bright areas and dark areas on the screen. Another technique in LED lighting is the “edge backlighting” where the LEDs are placed around the edge of the television to illuminate light inward. A disadvantage of this is that it can cause the colors to appear uneven and washed out. LED TVs are versions of the LCD TVs that have better color, contrast, and brightness.
As mentioned, LED TVs are very expensive and before buying one, you must consult LED TV reviews to know the qualities of the most popular LED TVs. The factors to look for when buying an LED TV are its features, display, and connections. It will also be good if the manufacturer provides adequate help and support to their clients. Below are reviews of some of the popular brands of LED TVs.
