Osram Opto’s new MULTILED boosts homogeneity for video displays

Osram Opto Semiconductors GmbH of Regensburg, Germany has launched a new MULTILED product, the LRTB GFTM, developed specifically for the video display market. The new MULTILED provides homogeneous display results and high color fidelity across the entire viewing angle required by the video display market, while its black surface enables good contrast in both indoor and outdoor environment, claims the firm.

As a further extension of Osram Opto’s black product series, the LRTB GFTM provides what is claimed to be excellent contrast and depth of color. “Because the RGB chips in the MULTILED series are arranged in a straight line, the displays look the same no matter from which angle they are viewed,” says KC Cheng, marketing director of Asia Pacific at Hong Kong-based subsidiary Osram Opto Semiconductors Asia Ltd. The high homogeneity suits application to video walls and displays.

Osram Opto says that homogeneous display results are also achieved by using its latest high-power Thinfilm and ThinGaN technologies. By supplying in very narrow distributions in terms of brightness and color location, the display colors remain constant from all viewing angles. 

Osram Opto claims that the new MULTILED also provides value for money, especially for volume markets in Asia. According to market research firm Strategies Unlimited, large full-color sign applications accounted for 9.3% of the high-brightness LED market in 2008. Also, according to iSuppli, China and Asia-Pacific will become the biggest signage and professional display markets by 2011. 

LED benefits have accelerated the adoption of LED displays, since the light sources contain no lead or mercury and offer much longer life time with less maintenance. In addition, like other members of the MULTILED family, the LRTB GFTM enables reduced maintenance costs, as its six-lead package delivers improved thermal management and increased reliability, it is claimed.
