But it's still fascinating technology. HP have been focusing on plastic backed displays for quite a few years now, and not just because it's sturdier than rigid displays (like E-ink and current LCD). They believe it will also be cheaper to produce.
HP are working with plastic films that are both lighter and thinner than glass. The manufacturing process starts with a roll of plastic that has been embedded with a thin film of metal and other material. The plastic is run through a press that imprints a pattern of three-dimensional transistors on the film. These transistors can transmit instructions to electrically charged particles or diodes contained in a second layer of plastic, which then displays text or images.
