Preview videos from Japan's massive tech expo







Ceatec 2010, the big Japanese electronics showcase, doesn't open until tomorrow. But CNET has some early videos from inside that provide a taste of what's to come.
First up is a look at what TDK calls an "QVGA organic EL see-through display" that provides 50 percent translucency--so the viewer can see the image in the display and what lies beyond. The company explains that when power is not flowing through the tiny screen, the display is transparent from both sides. But when the power switch is flicked the screen cannot be viewed from the backside.
TDK, a major component manufacturer, hopes to sell the technology to makers of cell phones and other portable devices. In the background you can see how the technology could be used in a head-mounted display for military or factory applications. Xbox 360, anyone? (Note the model's right hand as she covers the wires running up her sleeve from this prototype.)


Last up is another one from the TDK booth showing a video running on a flexible OLED display. Three of these displays stacked on top of each other would still be less than 1 millimeter, and they are flexible enough to be worn as a wrist band (a true wrist watch?). Besides consumer uses such as in toys, TDK envisions creative uses for the displays in advertising and in-store displays (around poles, for example)
