Just about everyone would like the screen on their handheld or smartphone to be larger, but very few people are willing to carry around a big, bulky device.
That's why several companies are working on flexible displays. These can be rolled up when not in use.
Scientists at Philips Polymer Vision say they will have a flexible display in production in about two years. This is a 5-inch screen with a resolution of 320 by 240 pixels.
The Polymer Vision PV-QML5 will offer four shades of grey, and use technology developed by E Ink Corporation, so it will require a small amount of power. It will have a contrast ration of 10:1, making text easy to read even in direct sunlight.
"Rollable displays will revolutionize the level of convenience with which we can access greater volumes and quality of information while on the move," said Karl McGoldrick, CEO of Philips Polymer Vision. "Information content will be a major mobile market driving force, and Polymer Vision's rollable display with 'paperlike' easy reading is strongly positioned to play a key enabling role here."
More information is available on the Philips Polymer Vision web site.
Other companies working to develop flexible displays, including Universal Display Corporation, are working on flexible OLEDs. OLED (organic light-emitting diode) displays take advantage of the fact that some organic compounds glow when an electrical current is applied to them. This means there is no need of a backlight.
