LG has released new information on its upcoming 55EM9600 55-Inch OLED HDTV. This new big screen technology was first displayed at last month’s 2012 Consumer Electronics Show. We’ve put all the information in the form of questions and answers covering topics including: white pixels, viewing angle, energy efficiency, wear and more. Read all the latest news after the jump.
What is the difference between Red, Green, Blue OLED and LG’s White Ones?
White OLED uses RGB color layers which are applied to the organic layer and act as color filters for the light being emitted. In contrast, RGB OLED requires separate red, green and blue elements be created individually for each pixel. This is a more complex arrangement which is more costly and difficult to scale to different screen sizes.
Why Not Make A RGB OLED Panel?
Using W OLED technology is more efficient to manufacture and create various screen sizes without sacrificing picture quality
Are There Any Advantages To Picture Quality Using White?
Both types of OLED provide expanded color gamut, infinite contrast, ultra-fast response times and thin, lightweight design possibilities. However, we believe that WOLED offers more natural color reproduction and better off-axis viewing than RGB type.
Do The Color Filters Cut Down of Viewing Angle?
No
Are RGB OLEDs More Difficult To Make?
Yes, the manufacturing process allows WOLEDs to be more easily adapted to different screen sizes and is more efficient overall.
Does White Have Better Color Stability Than RGB? Are They Energy Efficient?
Specs have not been finalized, but there’s no question that WOLED will be very energy efficient, perhaps THE most energy efficient flat-panel display technology to date. Regarding panel life, while long-life testing is still underway, we believe our WOLED will perform quite well vis-à-vis other displays.
The Upcoming LG OLED Has Standard 2K HDTV Resolution. Is 4K Possible?
WOLED can be adapted more easily to 4K resolution.

Obviously these two companies are not stupid. So why the different approaches to OLED? Theoretically which technology should provide the best overall viewing experience?
Much cheaper than ten thousand dollars (8000 euros)? It better be.
When making a comparison between WOLED and RGB OLED you neglect to mention that the color filter that is used to convert white to RGB sub-pixels causes a substantial decrease in light output and a good portion of the savings incurred by using WOLED instead of RGB is decreased by the cost of the color filter, which RGB OLED does not use. Also note that there is no such thing as a ‘white’ OLED, as white is created by mixing colors, in this case potentially two or more colors to make white. While this is certainly easier to pattern than RGB, this is more a ‘time-to-market’ issue for LG, as Samsung has a substantial lead in RGB OLED development and manufacturing. Remember, the only thing that will matter to consumers, regardless of the starting price, is does it work (dead pixels)?
Very good article, some LG Electronics manager told me today that the price will be much cheaper than 8000 euros.
Very nice, but a) how much does it cost, and b) when will it be available? That’s the real news we’re waiting for.
