[bunnie] just happened to be at the Embedded Systems Conference in San Jose on exactly the right day to witness the live teardown of a Sony XEL-1 OLED TV. The XEL-1 is Sony’s flagship OLED panel that’s only 3mm thick… and $2500 for just an 11-inch screen. [bunnie] was able to take quite a few shots of the components as they were passed around. He pointed out a few interesting bits about the construction. There seems to be quite a bit of thermal material on the display to prevent “avalanche thermal failures” (which I’m guessing doesn’t look as cool as it sounds). OLED displays are completely transparent and their legendary contrast ratio is just a result of the dark backing material. The mainboard seems to be a bit of overkill for this TV and [bunnie] concludes that it’s just the standard image engine architecture from Sony’s Bravia line put into a smaller package.

3D Video With Consumer Cameras
While perusing our photos from the Hooptyrides, Inc. tour you may have noticed [Eric Kurland]’s two handed stereoscopy rig. It’s constructed from two consumer grade Sony DV cameras. The problem with using two separate cameras to make stereo images or video is that a lack of clock sync will make objects appear out of their true position because of differences in framerate. To solve this problem Damir Vran?i? developed the 3D LANC Master. It reads the crystal frequency from one of the cameras and writes to the ram of the other camera using Sony’s LANC protocol. This constant monitoring keeps the clocks within +/- 3ms. The control box also has buttons to power on, zoom, and record in sync. The 3D LANC Master plans are completely open source and work with a large number of Sony cameras. We have more photos of Eric’s rig after the break.
