Flat Panel Displays --- Principles, Materials and Processes
... • Electrons are generated by field emission rather than thermal
• Less power consumption and instant turn-on; wide viewing
angle; high color saturation.
• Sub-micron tips: Low work function material, sharp tips,
suitable emitter materials.

Electronic paper, e-paper and electronic ink are display technologies that mimic the appearance of ordinary ink on paper. Unlike conventional backlit flat panel displays that emit light, electronic paper displays reflect light like paper. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without the image appearing to fade.Many electronic paper technologies hold static text and images indefinitely without electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. There is ongoing competition among manufacturers to provide full-color ability.Applications of electronic visual displays include electronic pricing labels in retail shops, and digital signage, time tables at bus stations, electronic billboards, mobile phone displays, and e-readers able to display digital versions of books and e-paper magazines.
