Panasonic showed off an early transparent TV before, but the company has now improved the image quality to the extent that the idea of a TV built into your furniture's glass panes is not only possible -- it's right here. The OLED screen is made of a fine mesh, embedded into the glass sliding door. While the TV image is visible even with the backlighting on, once it's dimmed, the image is clear and bright enough to be almost indistinguishable from existing TVs. (The last model was a bit too dim, and required undershelf lighting to boost the image.) Turn the TV panel off, however, and it's hard to tell it was ever there to begin with. Want one? Panasonic's spokesperson says the TV is likely to stay in development for a few years longer: at least another three years.
