Resistive LCD Panels Improve Sunlight Readability

New four- and seven-wire resistive circularly polarized touch panels use transmissive LCDs to eliminate over 60% of reflected ambient light while maintaining 79% luminance transmissivity. The FID-554 series from Fujitsu Components America is designed for portable and stationary outdoor applications like kiosks, navigation systems, industrial instruments, and test instrumentation.

The touch panels employ a 1/4-wave retarder and a polarizer to prevent light that passes through from being reflected back to the viewer's eye. As a result, the high-contrast display becomes very readable in sunlight conditions.

The panels feature a minimum surface hardness rating of 3H and a minimum life of 1 million operations. Available in a variety of sizes, they suit both pen and finger inputs. The custom products are compatible with standard controllers and device drivers available from Fujitsu.

Estimated pricing for the FED554 custom product series begins at $25 each in OEM volumes. Lead times are within 12 to 14 weeks.
