According to Scientists, we can expect that flexible displays (that can be rolled up!) may be in mass production in the very near future. This may change the way we use our mobile devices. New technology will use oil and water to produce images (it's an OLED alternative).
How does it work? Instead of making pixels out of OLEDs, there are designed out of oil and water contained in tiny plastic cells connected to plastic electrodes. The oil, which is opaque, floats on the water and obscures a coloured surface beneath. But applying an electric field forces the oil away from the water, revealing the coloured layer beneath and changing the colour of the pixel.
The process of production is cheap and simple, which hopefully will make possible reading a completely digital morning paper using mobile device (imagine being able to unroll an A4-sized display out of a device little bigger than a pen).
Would you like to use such a toy every day ?
