Fujitsu has figured out to make a 4-inch display for PDAs with a resolution of 800×600 pixels, which is a big step up from the 320×320 of Palm’s Tungsten C, and high enough for watching digital television:
It will also show an entire web page, Fujitsu boasts – but we reckon PDA users will need major eye upgrades if they want to be able to read the text. The new display doesn’t so much add extra pixels as more cleverly use ones already there. Instead of separate red, blue and green pixels of the kind found in today’s LCDs, the Fujitsu system uses fast-changing colour backlights to allow a single pixel to display any of the three primary screen colours. The upshot is an effective three-fold increase in the number of pixels.
It’s just a prototype, so it’ll be a while before it starts showing up in handhelds you can buy.
