Without a doubt, Light Blue Optics has combined electronic (e-books) are the success holographic projection technology with story of 2010. According to .com, infrared touch-recognition technology sales of e-books have now exceeded to make a pico projection system those of hardback books, and it is display that allows users to interact with the technology that has made e- readers a projected content (see page 750). Finding practical option in terms of their readability applications for such an ingenious and battery life. Most of these devices technology requires little imagination — feature a black and white electrophoretic you could do your internet shopping by display technology developed by E projecting the website onto the table and (see page 748), a company that started choosing the items you want by touch, or after its founder ran out of books to read project an interactive presentation onto on holiday. What makes these displays your desktop at work. different to other types of display is their The pico projection market is also a bistable nature — power is only needed growing opportunity for microdisplays when turning a page. The demand for these made using liquid crystal on silicon (see Cover image low-power displays is now bigger than ever, page 752).
