At the CeBIT 2007 show in Germany a company called Shenzhen Truth Digital Technology (also for some reason known as TRUS) showed off these USB flash drives sporting a monochromatic LCD screen. Now the exact details are a bit sketchy at the moment but the flash drive apparently includes a built-in solar cell which is used to power the LCD display.
Given a lack of buttons or controls on the drive the screen is probably only used for displaying the available storage space remaining so a solar cell coupled with a small capacitor would probably provide enough power. As for a release date and storage capacity for these drives? I’ve no idea but somewhere between 512Mb to 4Gb is probably a safe guess.
