Back to LED/LCD TVs. There are two forms of LED TV’s available. Both of these television types have LCD displays. They are illuminated and lit by LEDs, making them a LCD and LED mix. These televisions can be backlit by LEDs, or edge-lit from the side of the screen.
 About LCD Displays
LCD displays started the flat panel television, paving the way for the multiple types of flat screen TVs. The LCD display allows for a clearer picture, and comes in the form of a lighter television.
The liquid crystals in a LCD (Liquid Crystal Display) all face in one direction. When the electric field is created, the crystals align in the images for the screen. The lighting then illuminates the screen displaying the colors, creating the full display.
About LED Technology
The LED technology is what brings the LED TV to a new level. The LED technology replaces the old fluorescent lighting that used to be in TVs. Small LEDs are placed behind the TV or on the sides of the TV.
LED TV’s can use two types of LED lights. Some TVs use RGB LEDs. Others use white LEDs. Both types of LEDs offer benefits over the old fluorescent tubes.
 Benefits of the LED TV
The major benefit of LED TV comes from the LED technology itself. Fluorescent tubes were not able to create a deep black, as they were always on. LEDs allow for a deep black. This gives greater contrast to the screen.
LED TVs are thinner and tent to be lighter than normal TVs. Side-lit LED TVs are the thinnest of them all. Both have excellent contrast.
