3D OLEDs

Sony's VP of solutions engineering in the US Pete Ludé says that 3D TV could become an important market for OLED displays. Sony says that while LED LCD 3D TV are effective, but only if the resolution and refresh rate is not too high. Active-Shutter 3D needs double the refresh rate (because it alternates between the two eyes), so 120fps needs a 240Hz TV - or higher. At these rates, OLEDs are easier to use. OLED TV panels also offer less crossover between the stereo images.

Sony are looking into OLEDs, and are still enthusiastic about the technology, are not yet committed to OLEDs as the technology of choice for long-term 3D displays. In CES 2010, Sony has demoed a 25.4" 3D OLED prototype (shown above). Samsung are also very confident about large OLED TVs for 3D.

Back in January we posted about 3D being the "killer application for OLEDs".

Germany's Sterrix Technologies has filed a family of patents for a new OLED based 3D auto stereoscopic  (no glasses) display. The resolution of this display will be 100 times higher than HD images, which can be used to create more than 100 perspective at the same time - allowing for smooth 3D images from any viewing angle and any distance. The display has over 1000 cores (inline processors), needed to create those perspectives.

This display uses a new pixel structure which on one hand consists of colored pixels, and on the other hand consists of pixels, which are adapted to the anatomy of the human eye by presenting additional image information. Through those pixels it’s easier for the human brain to internally generate the spatial image, which makes it more relaxing viewing 3D images and videos on the display.

PureDepth announced today that they have acquired a patent for Multi-Layer 3D OLED displays. PureDepth Multi-Layer-Displays (MLD) use two or more displays that are placed one in front of the other to create 3D effects. These 3D displays do not require glasses and provide real depth.

One of the markets the PureDepth are targeting are mobile devices, and OLEDs are becoming more and more popular in that market. Up until now PureDepth had only LCD related patents, but now they can work on 3D OLEDs, too.

It seems that LCDs aren't the best technology for 3D TVs. Plasmas are better, and OLEDs are best. OLED-Info discusses whether 3D TV will be the "killer-app" that will finally enable real commercial OLED TVs...

Sony are demoing new 24.5" 3D OLED TV displays. This is just a technology demo, Sony hasn't announced any plans for newer and larger OLED TVs yet, let alone to commercialize this 3D set.

Samsung will show today a new 14" qFHD (960x540) 3D OLED prototype. This display has a contrast of 100,000:1, color gamut of over 100% NTSC and is only 1.6mm. OLEDs are great as 3D Displays - the image switching is very fast, and there's no optical crosstalk between the two 3D images, according to Samsung.

Samsung is showing a new 30" 3D OLED TV panel with Full-HD resolution, and a 1,000,000:1 contrast ratio. The width is just 2.5mm. It uses Samsung's SEAV (Simultaneous Emission with Active Voltage) 3D technology. To view the 3D image, one must use special glasses.
