World’s Thinnest TV: LG OLED TV vs LED TV

LG wowed us a month ago with their world’s thinnest OLED TV at CES 2012. I was blown away by its infinite black level and ultimate picture clarity, not to mention, its unbelievable 4mm thin panel. Even though my LED backlit LCD TV is working fine, I can’t wait to ditch it and get a LG OLED TV which is about to be released in the US pretty soon.

 

LG boasted how thin their OLED TV was at the press conference. It is only 4mm thick, which is less than half of that of the iPhone 4.

 

When LED TVs first hit the market in 2009, they were about 30mm thick but became thinner and thinner because of advancement in technology. What made it possible for OLED to transcend the limits of LED when it comes to thickness of the panels? Let’s take a close look at what the layers of both TVs are composed of.

OLED TV consists of 4 different color pixel layers, a thin film transistor, a color refiner and a polarized film. Since the organic pixels of OLED TV light themselves and work independently, there is no need for a backlight unit and other supporting structures.
