Sharp Corp exhibited prototypes of LCD panels using its moth-eye reflection-free film at CEATEC JAPAN 2012.

The company showed 60-, 70 and 80-inch prototypes, which they said will be commercialized as early as possible.

The moth-eye film has regularly-arranged protrusions measuring several hundred nanometers on its surface. Because its refractive index in the depth direction changes in a continuous way, it can reduce light reflection.

"It has both the transparency of glare panel and the low reflection of anti-glare panel," Sharp said.

Sharp developed the moth-eye film in collaboration with Dai Nippon Printing Co Ltd. Sharp improved display performance by fine-tuning the quality and thickness of an adhesive material at the time of attaching the film to the surface of an LCD TV screen, it said. The company did not disclose the contrast ratios of the panels.

Despite the regularly-arranged protrusions, the strength of the film is high enough, Sharp said. However, it also said, "Maintenance should be carefully done. For example, when a fingerprint is put on the panel, it should be removed by using a wet towel."
