Korean researchers developed a new glasses-free OLED based 3D technology that uses tiny prisms - called lucius prism. The idea is to use an array of these microscale prisms, each basically an OLED to create two different images - one for the right eye and one for the left eye. Currently the researchers describe a four-centimeter square prism array, although they estimate that they can make it larger, to make a 3D TV. The prism array was made from photocurable polyurethane acrylate (PUA), although any kind of transparent polymer could be used.
Back in CES 2011 Sony showed a prototype Head Mounted Display (HMD) featuring two 1280x720 OLED microdisplays. It was just a prototype back then, and now Sony announed that they will release the HMD (called HMZ-T1) in November (in Japan at first) for ¥60,000 (about $780). Sony uses Dual Panel 3D technology which utilizes separate panels for the left and right eyes, each with its own dedicated 3D video.
These Sony-made OLED microdisplays are 0.7" in size each and use the same technology as Sony's recently announced 0.5" microdisplays.
Samsung developed a new 5.2" glasses-free 3D AMOLED panel for mobile applications. Samsung uses a six-subpixel structured white OLED with color filters. The 3D is achieved using fixed parallax barriers and the AMOLED panel features only about 5% crosstalk and is only 1mm thick.
Samsung will present this new panel at SID 2011 (May 15-21). There will be a lot of other OLED presentations and new devices shown at SID.
OLEDNet has published an article on OLED TVs. They basically say that the technology to make OLED TV is getting ready - but companies (such as Samsung and LG) need to be ready for huge investments. They claim that if OLED 3D TV production won't start by 2013, it might miss the 3D TV bandwagon altogether.
The idea that 3D is a "killer-application" for OLEDs was raised back in January 2010, and since then we heard Samsung, Sony and other company claim that 3D will drive OLED TV growth.
Sony has unveiled a new OLED TV prototype, this one is a 24.5" model that supports glasses-free 3D. Interestingly, Sony plans to launch this TV during 2011 - but for the B2B market (for professional broadcasting use). The quality is great, but the price will be very high of course, so Sony cannot market this to consumers. This is not Sony's first OLED aimed for broadcasting professionals - they also offer the PVM-740 monitor that has a 7.4" OLED (but no 3D).
Update: It seems that the OLED microdisplays are made by Sony themselves and not by eMagin...
Sony is showing a new 3D Head-Mounted-Display (visor) prototype - that uses two 720p (1280×720) OLED microdisplays. Other features includes 5.1 surround audio and a blue LED strip on the front.
This is just a prototype, but it's good to see Sony using OLEDs there (the OLED microdisplays are made by Sony).
According to LG's official flickr account, the company is set to reveal a new 3D OLED TV panel that will be based on the company's new Film-Type Patterned Retarter (or FPR) technology. FPR adds a polarized filter to the TV which enables 3D using passive glasses - which are cheaper than active-shutter glasses. LG also claims that FPR eliminates flicker and crosstalk.
We're not sure if this new OLED TV will be the same as the 31" one unveiled in August 2010 - which also used polarized 3D glasses. But the FPR technology is said to be new, so we do not know. We'll have to wait and see...
Samsung is showing a new flexible 3D AMOLED TV concept - this is one of the ideas that they came up with in their design-your-display contest. The idea is that you can actually fold the TV, and thus get optimum 3D images - from anywhere in the room (not just in front of the screen).
This is just a concept, though - not even a prototype. This technology is probably 5-10 years from being commercialized...
LG is showing a new OLED 3D panel for mobile devices. This is an autostereoscopy (glasses-free) panel with a 360x640 resolution in 2D and 360x320 in 3D.
