December 15, 2005... New LED Incorporates Lens for Large Display Backlighting Applications
San Jose, California USA--Osram Opto Semiconductors, a leader in light-emitting diode (LED) technology for display applications, today announced yet another addition to its Golden Dragon LED product family. The new Golden Dragon Argus provides uniform backlighting with perfect color Mixing, ideal for large display applications and suitable for backlighting a 32- to 82-inch liquid crystal display (LCD) panel.
Display backlighting requires a uniformly lit flat light source rather than a point light source, said Ellen Sizemore, director, LED Products Group, Osram Opto Semiconductors. The integration of our patented Argus lens into our already high-performance, thin-film Golden Dragon LEDs Enables flat, uniform lighting and paves Osram Opto Semiconductors way into the emerging, large-area, LCD backlighting market. We continue to look for new and innovative ways to further advance LED technology in both consumer and commercial applications.
Each new Golden Dragon includes a proprietary lens that enables the products high luminous efficacy. The Golden Dragon Argus assembly includes four thin-film, highly luminous LEDs (two green, one blue and one red) in a marquis jewel arrangement. Any number of marquis Configurations can be combined, either offset or in rows, to form infinitely scalable, high-intensity backlighting systems. The Argus lens system is a well-known LED component of Osram Opto Semiconductors radial LED product portfolio. Osram has now adapted the system for use In its surface-mount technology LEDs, including its Golden Dragon. The result is the transference of Argus LEDs optical properties to a high-output light source, enabling bright light to be emitted sideways over the entire surface.
Backlighting systems based on the Golden Dragon LED achieve uniform white light distribution using the red, green and blue spectrums of Osrams thin-film and ThinGaN (gallium nitride) technologies. This technology allows the highest brightness levels at the lowest operating voltage, is scalable and Each LED can be individually controlled to change the color hue using the Golden Dragon LED footprint with a low-profile optics package height of only 4 millimeters (mm). Golden Dragon Argus LEDs and lenses are much smaller than comparable systems, Enabled extremely low-profile LCD assemblies.
Golden Dragon Argus LEDs provide a switching time of less than 100 nanoseconds (ns), creating an ideal solution for sequential coloring, a process in which the three basic colors are pulsed at high frequency and in a particular sequence. As the speed of liquid crystals The human eye can be followed by high-speed changes and instead views the process as full-color moving pictures of exceptional brilliance. Pulsing ensures The moving pictures are sharp with excellent contrast, enabling the light sources to be faded to any level of brightness with distinguishable clarity.
Large displays, from 32- to 82-inch prototypes, backlit with LEDs do not need active cooling, even at high outputs. They contain no lead or mercury and comply with Restriction of Hazardous Substances (RoHS) guidelines. They are vibration and shock- Proof and offer a lifetime of more than 50,000 hours.
Availability
Golden Dragon Argus will be available in January 2006 in white, red, green and blue. Samples are currently available. For further information please visit Osrams web site at
