SHARP INNOVATION OF THE MONTH – LIQUID CRYSTAL DISPLAY IC CARD READER

Smartphones with the “Osaifu-Keitai” mobile wallet function, as well as IC cards accepted on public transport and in shops, currently exchange information with readers at distances of up to several centimeters by using wireless radio waves.

Those readers have built-in metal antennas, but when Sharp tried to build the antennas into LCDs, they obscured the displays.

Sharp overcame the problem by using super-thin antennas and attaching them to LCDs, creating the sensitive and speedy new display without compromising its appearance.
