LED Television Technology Explained

When buying LED TVs there can be a overwhelming number of options to weigh before making a purchase. For starters, simply deciding to choose an LED TV over a Plasma TV or LCD TV is enough to give you a headache. This guide will try to hit the main topics and information to consider before choosing whether or not an LED TV is best for you and what to look out for.

To begin with, we’re going to go over what an LED display actually is. In reality the screen of an LED TV is the same as LCD TVs. The difference between the two lies in back lighting of the screens. Traditional LCD displays use a fluorescent light to backlight the display and create contrast and brightness. LED televisions use a light-emitting diode (LED) in place of the fluorescent light, this tends to create a wider and deeper range of colors, blacks and smoother brightness than LCD TVs. oneplus led 32

Even inside of the category of LED televisions there are options to consider.There are 2 main types of LED displays (RGB dynamic LED and Edge-LED). Each one is suited for different viewing and cost needs. Right now we’re going to try and talk about the pros and cons of each type.

RGB dynamic TVs use a series of 3 LEDs, red green and blue. Varying the projection of each diode creates different temperatures of white. These are positioned in different areas of the TV to retain the original colors of the display and to be able to create higher contrast and truer blacks in different areas of the screen. The drawback to this type is that you have a loss in detail on small bright objects in large areas of darkness.

Edge – LEDs use a special array of LEDs to diffuse light across the screen in a uniform brightness distribution. This creates a dramatically thinner and lighter TV than RGB LEDs. It also consumes far less electricity than it’s LCD counterpart. The downside is that there can be frame heating issues and uniformity in brightness, but these are mostly hard to notice to the untrained eye.

Overall, LED televisions offer much richer picture quality than that of traditional LCD TVs and mostly on par if not better than Plasma TVs. Not using a fluorescent light creates a more vivid image on screen and much deeper and richer dark areas that are more controlled.

Another thing to consider is the impact on the environment. LED TVs don’t use mercury during their manufacturing, and produce less amounts of carbon dioxide. This along with the lower energy usage compared to LCD leads people to consider it a more environmentally conscious choice.
