3M Co.'s optical systems division has highlighted some energy-efficient exhibits at FPD International, Oct. 28-31 in Yokohama, Japan, which highlighted the company's latest Vikuiti optical films for notebooks, handheld devices, monitors and LCD TVs.

"Power usage has become an increasingly important issue in today's electronic devices. Our FPD International exhibits leveraging Vikuiti optical films for notebooks, monitors and TVs show ways to enhance the energy efficiency of today's electronic devices without sacrificing display performance," said Jim Bauman, VP, optical systems division, 3M.

3M has launched its new Vikuiti Dual Brightness Enhancement Film (DBEF) for LCD TVs, the DBEF D3-300, which the company said can lower power consumption for LCD TVs by up to 37 percent, without sacrificing image quality. The optical film also claims to increase brightness by recycling polarized light, enhance viewing angle and uniformity, and draw away the need for a diffuser sheet, which reduces the overall BOMs.

3M also displayed the energy-saving power of its optical films with a 32-inch LCD TV running on just 60W and a 40-inch LCD TV running on less than 100W. These highly efficient LCD TVs have Vikuiti optical films with prism film, back reflector and reflective polarizer. These films have an increased brightness that helps makers to eliminate many bulbs in their backlight designs, requiring less power to produce the same brightness of a similar-sized TV with no Vikuiti film, according to 3M.

The company also showed its newest notebook film dubbed the Vikuiti Brightness Enhancement Film-Reflective Polarizer for notebooks (BEF-RP NB). 3M said the Vikuiti BEF-RP for notebooks can increase brightness by up to 44 percent and extend notebook shelf life from 14min to 17min beyond that of a standard film stack. It added that the film integrates a reflective polarizer with a prism film that is only 225? thick, allowing displays that are 90? thinner than using two separate films while providing a wider viewing angle.

"3M demonstrated a 19-inch Lenovo monitor, leveraging a combination of Vikuiti optical films that need only 20W of power to operate, with a 30-percent energy savings compared to other similar-sized monitors," 3M earlier said. It added that by recycling and directing more light to the viewer, the Vikuiti films help monitor makers to remove two bulbs, maintain brightness and meet total cost of ownership and lifetime standards.
