LG Display says True RGB OLED-Tv can not compete with WRGB,

The Global communications Director Ken Hong, spoke at the IFA-2014 about LG-Displays OLED-Tv investemts and their competitior with True RGB OLED-Tv (Samsung).

LG Display bought the patent rights for the white OLED technology from KOdak nobody thought that this deal can be a successful business. Kodak developed the white OLED panel technology and LG bought this patents that allows to get this 80 percent plus yield. This decision brings LG-Display in a very good position their rivals can not compete with this technology, LG think no competitior can catch us for 2-3 years. I hope you can remember our article Why LG Display will dominate the OLED-TV panel market in 2014? By the way the LG pays 100 million dollar back in 2009 to get that kind of gold mine. LG invest a lot of money also in some new production lines to achieve high production quantities for its 4K OLED-Television. On the other side Samsung Display has no plans to introduce True Pixel RGB OLED-Tvs soon. Maybe we see 2015 with some new architecture technology some new panels from Samsung. And LG says our competitor says the customers are not ready for that kind of panels, LG thinks they’re not ready. They don’t know how to do it, they missed the boat and now the ones who are stuck with regular RGB OLED are never going to get 80 percent.”

Ken Hong: thinks that a production line using RGB technology is not ready to earn money. For small displays it is ok Super-Amoled is RGB technology but only small/medium sized. If you want to produce larger panels there are a lot of errors.
LG is ready to sale their 65 inch 65EC9700 4K OLED-Television in Oktober also in the United States.
The 65 inch 4K model will kost 10.000 Dollar, the 77 inch 4K model 77EG9700 will be ready for shipment in November for about 25.000 dollars.

Inside LG Displays WRGB technology:

What technology has been used to create WOLED technology?
three main process to greate OLED:

• TFT (Thin Film Transistor) controls the electronical signal
• OLED
• Encapsulation

LG Display use a Oxide TFT Backplane with improved TFT performance, this allowded to create large display size, high resolution and productivity.


Samsung FMM LTPS True RGB technology issues:
In the small/mid range AMOLED displays there are no problems with the manufacturing process. Samsung Display use here LTPS Backplane with FMM Fine Metal Mask. But if you want produce larger displays like television devices this technology has some technical limitation. Samsung Display is using an RGB separated AMOLED panel based on low-temperature polysilicon (LTPS) TFT. At the moment January 2014 they can produce 10.000 sheets per month in their 8G production line.

With FMM their is no problem at the small/mid range segment:

FMM Fine Metal Mask has some issue at larger panels:
