LED Tehnology vs LCD

 LED TV have been around for some time now and have become the new “high end” TV on the market. They are just an LCD TV that is back lit or side lit with LED lights rather than the typical fluorescent lights used in common LCD televisions. So, for those of you who are a little lost on what this means, we will go over the differences between the two types of televisions.

LCD Technology
Your basic LCD (liquid-crystal display) television uses a type of lighting called cold cathode fluorescent lamps (CCFLs) to light up the crystals on the screen and display a picture. These light bulbs are as long as the TV and simply light up millions of LCD shutters that are arranged across the screen. Each shutter lets in a specific amount of white light to produce either a very bright color such as yellow or a very dark color one such as brown. Each shutter has a colored filter behind it which allows it to remove the red, green or blue portion of light. Depending on the type of display you want to buy these shutters and liquid crystals are placed between two glass sheets or plastic sheets and then placed in the TV frame. The glass finish is going to give you a very clear and amazing picture and will also give your TV a very slick finish. The plastic finish will allow you to have the best picture possible and a lot of extra glare from the lighting.

LED Technology
LED TVs are in fact LED LCD TVs because they use the same LCD display but are illuminated by a different type of light. Instead of using long tube-like lights (CCFLs) to illuminate the liquid crystals, an LED (light-emitting diode) light is a much smaller light source which can be placed in zones behind the screen to produce what is known as local dimming. This type of lighting allows for pinpoint light adjustments across the entire screen. Another type of LED lighting is called "edge backlighting," which means that the LEDs are placed all around the edge of the TV and illuminate inward. at the same time this type of lighting helps to produce extremely thin displays, which is becoming very popular.

As you can see, LED TVs are in fact just LCD televisions that use a different type of lighting. The main reasons companies are moving toward this new type of technology is because it boosts LCD brightness, contrast ratios and color and it's the most energy efficient and long-lasting technology available.
