When introduced at CES 2012, LG’s 55-inch OLED TV, with its stunning images, displayed in a quality never before experienced on TV left the record 153,000 visitors to tech’s premier tradeshow abuzz over the future of TV.

Fast forward six months and anticipation is again mounting as consumers and the industry prepare for the upcoming commercial release of the first OLED sets. However, at first, as buying an OLED TV will require a big investment, it’s important you understand the technology and that you’re choosing the best OLED TV possible.


What is OLED? Why LG OLED TV?

Basically, OLED (Organic Light-Emitting Diode) panels emit their own light when an electric current is passed through, whereas cells in a LCD display require an external back light source. Because OLEDs do not require backlighting, they permit exceptionally thin design and greater energy efficiency with lower power consumption. They also boast unrivalled picture superiority delivering truly deep blacks. As a result, OLED technology for TVs is truly setting the agenda for the industry and receiving wide recognition as the ultimate TV viewing experience.

However, it’s important to know there are actually two types of OLED TVs, RGB OLED and WRGB OLED which is used by LG’s OLED TV – and the difference matters greatly in terms of overall viewing experience.

Specifically, RGB OLED uses 3 color pixels, Red, Green and Blue while WRGB OLED uses 4 color pixels that includes an additional white sub-pixel.

A key differentiator, one of the most important benefits of the extra white in WRGB OLED is the ability to produce highly accurate colors for a more realistic experience. Let’s find out how.

RGB + White: Greater Color Accuracy

To form a color, three colors (one red, one green, and one blue) must be used. Each of them can have an arbitrary intensity, from fully off to fully on, in the mixture. By adding a white color pixel to the RGB, WRGB dramatically enhances color precision and offers greater color accuracy. If you look at the center balloons above, WRGB does a far better job in replicating the exact color than does RGB.

With WRGB OLED, picture color quality replicates the actual color being portrayed more accurately than ever before.

Sophisticated Color Refiner technology in LG’s WRGB OLED TV also adds to the enhanced viewing experience with more natural colors and a wide viewing angle.

120% Color Range: More Natural

In addition to the extra white color pixel, LG added the Color Refiner to perfect the color output. As a result, WRGB OLED matches the international standard range for HDTV (BT. 709), and it is most evident with images that require extensive use of the blue pixel. In comparison, RGB OLED is incapable of meeting the entire international standard range for HDTV. That’s why the blue color of the bird in the left image above is not fully realized.

So in a nutshell, the OLED technology with added white sub-pixel supports a greater color range to produce a broad array of colors that reflect the most realistic and natural depiction of the world around us.

Less Distortion: More Consistent Wide-Viewing

WRGB OLED with the Color Refiner allows for absolute color consistency and precision, enabling WRGB OLED TVs to have complete color consistency from all viewing angles.

You can watch your TV on the couch, lying down in bed, from across the room… Basically from anywhere without any distortion!

The Experts Agree: WRGB OLED Wins Hands Down
