LED: A LED display is often regarded as the best platform to display your content. The picture is displayed via an array of light emitting diodes as pixels. The thin layer of back-lighting allows manufacturers the ability to create ultra-thin screens. LED TVs generally have the least amount of reflection and are best for well-lit areas.
OLED: An OLED display has more control over the back-lighting of the image. Each area of the screen can adjust giving blacker blacks and a higher quality image. This increased control also saves on power consumption, making this a great upgrade from a standard LED screen.
Plasma: Plasma TVs are outdated technology. Bulky equipment, the high probability of a burned-in image and the fact that many manufacturers have discontinued their plasma lines make this a bad choice.
LCD: Although LCD screens produce a slightly thicker and heavier TV they are a great bang for your buck. This display type still utilizes back-lighting to display the image making it brighter than plasma screens.
