It seems that the display screen of smart phones is growing proportionally with its growing fan base. That is why probably mobile phone companies are spending heavily on research and development of folding and rollable displays. These proposed displays have actually started a kind of rat race between companies as the first one to come up with these phones could easily hit a goldmine.
Taiwan’s Industrial Technology Research Institute (ITRI) in association with PilotFish have engineered a TFT-EPD (Thin Film Transistor Electrophoretic Display) panel that could solve the display solutions for Smartphone manufacturers. It has a folding top display and a bottom sliding display which literally doubles the screen size to a whooping 5 inches. The two displays are separated by a 1cm flexible strip. In the images you would it appears that there is actually a break in the center of the complex display but actually it is the software taskbar. The next step which companies are gearing up to is bringing touchscreen feature into such large screens and it is expected to be made available for use sometime next year.
