Just know that not all LED TVs offer local dimming. These days, even some edge-lit TVs use a form of local dimming technology to improve the overall image quality. The end result is a better perceived contrast and better overall black levels. Some also offer "local dimming," which allows different areas of the screen to be shut off or diffused. In order to make the backlight more uniform, they also use a diffuser panel. This type of LED allows for a very slim bezel and the greatest energy efficiency.įull-matrix LED TVs use a full array of LEDs across the back of the display.

These lights shine into a multi-layered diffusor panel, providing a uniform light source behind the LCD panel. Here comes the monkey wrench: There are two types of LED TVs to choose from.Įdge-lit LED TVs have a row of LEDs that wrap around one or more edges of the panel. Now that you know that you want an LED TV, it's probably a good idea to know what kind of LED TV. Samsung's ES8000 Series has Micro Dimming Ultimate technology and a built-in TV camera. However, it's important to note that despite having a slimmer appearance, a brighter image and better picture quality, LED TVs are actually more energy-efficient so you can feel good about your carbon footprint while kicking back to watch your favorite shows. LED TV is a lot thinner than its LCD predecessor. LED TVs generally boast better brightness and contrast over LCD TV, which means brighter whites (and other colors) and deeper blacks.īesides the on-screen image, there is a noticeable difference in the outer appearance of LED TVs. While both LCD and LED TV use LCD panels to create the image, LCD TVs use fluorescent tubes to light up that image while LED TVs use LED lights positioned along the sides or back of the TV to make that bright picture possible. However, LED TV (a variation of LCD TV, using an LED backlight) has been gaining momentum for the past few years, and is becoming one of the more popular choices for HDTV shoppers today.īorn out of LCD, LED TV is a relatively new TV technology. Of course, LCD and plasma are still alive and well - and the fans are still there, too. Oh, how times (and the technologies) have changed. Sometimes, it just came down to what was most affordable, with the larger TVs in both technologies carrying enormous price tags.

Both technologies had their share of fans, their advantages and challenges. Years ago, when you wanted to buy a flat panel HDTV, there was really just one basic choice to make: LCD or plasma.
