Panasonic 56" 4k oled!

"Panasonic unveiled a 56" 4K (3840x2160) OLED TV panel prototype that was produced using an all-printing method. Panasonic calls this the "RGB all-printing method" and they say that all the organic materials were deposited using ink-jet printing. Panasonic says that their OLED panels deliver superb image quality, high contrast and fast response rate. The panels are efficient, ulta-thin and light weight. Panasonic considers OLED as a "promising option for next-generation displays".







Panasonic's panel uses a top-emission structure with a transparent cathode, which results in a more efficient panel (Sony's OLEDs use the same structure, this may be Sony's technology). The panel's TFT substrate was supplied by Sony (so it's probably an Oxide-TFT based panel) as part of the two companies collaboration. Interestingly, even though it seems that they use red, green and blue sub-pixels, Panasonic applied a color filter layer as well - to tune the emission color and achieve high color purity and "superb color reproduction".


Ink-Jet printing is a promising manufacturing process to produce OLED panels as it's quick, precise (i.e. enables high pixel densities) and efficient (very little material waste). This kind of process requires soluble OLED materials.

Back in September 2012 it was reported that Panasonic has taken steps to streamline its R&D and put more focus on OLED TV development, with plans to invest ¥30 billion ($385 million) in a pilot AMOLED production line in Himeji (this was already reported in April). It's likely that this new panel was indeed produced in that Himeji R&D line.

Panasonic has been working on OLED printing technologies for quite some time. Back in 2009, Panasonic teamed up with Sumitomo to jointly-develop OLED TVs, based on Sumitomo's P-OLED materials and technology. I don't think this partnership is still active. Sumitomo is building a large P-OLED material factory aiming for OLED TV applications - perhaps this TV uses those materials (although it's also likely that Panasonic is using small molecule soluble materials).

Panasonic is collaborating with Sony on OLED TV panel production technology. Sony just unveiled their own 56" 4K OLED TV prototype, developed together with AUO, and as far as we know is made using an evaporation process.

I just wish that one of the manufacturers would make an affordable oled tv, ive been waitin for about 10 yrs now since i first heard about the tech and really thought they would be in the shops and affordable by now.

Yes i realise you can buy one now but im after a tv for us mere mortals instead of richard branson, bill gates, sheikh whoever etc etc.

Well now just about everyone in the world has replaced their CRTs with LCD and Plasma, and LCD can't be developed any further - they will now want us to replace them all again with OLED. Wait until the marketing machines start pushing these TVs onto the average brain dead consumer and they will soon drop in price and be everywhere

Looking vs this tv oled n 4k for me is the perfect combo

Surprises me that some people seem so desperate for this technology when they have no idea how it performs. Does it have any downsides? I suspect it does otherwise it would have been mainstream by now. Manufacturers will go for a big launch when they can make the product cheaply, with maximum profits. Look at the early Plasmas, not HD, not even UK SD definition, yet they were sold at thousands of Pounds until the public twigged they were being taken for a ride. Let's see what moderate size HD screens perform like before getting too excited because something is 'new', which OLED certainly isn't.

OLED production yields are very low, i.e. it is very difficult and expensive to manufacture, that is why the technology is not mainstream.
