By "improving the transmittance of the panel and the luminance efficiency of the backlight," Tech-on! notes, the company was able to keep power consumption down to 6.3W -- low enough that a forked USB 2.0 cable is sufficient to power the thing as well as supply data. The only drawback? Apparently the device uses an edge-lit backlight that limits the device's lifetime to 30,000 hours compared to 50,000 for existing LCD monitors).
