RGB Multi ChipLED

Small multicolor LED
SUNNYVALE, Calif., May 18, 2009 – Osram Opto Semiconductors Inc. has developed the smallest member of the RGB Multi ChipLED family to bring high-definition picture quality to large full-color video screens. The LED enables high-resolution screens, such as those found in television studios, modern conference rooms, trade fairs and concert halls, to offer bright colors and high contrast from all viewing angles. Its compact dimensions accommodate a large number of pixels in a small display area. Housed in a black package that is mostly impervious to ambient light, the LED emits light in brilliant colors with good contrast.

Osram_Tiny-LEDs.jpgThe package measures 1.6 × 1.6 × 0.9 mm, and pixel spacing is 2 mm. An area of less than 10 m² is sufficient to display pictures in HDTV quality and to accommodate more than 2 million pixels. A 2.5 × 4.0-m display that measures 10 m diagonally can achieve a system luminance of 1500 to 2500 cd/m², corresponding to approximately 10 times the luminance of a conventional LED-backlit thin-film transistor LCD screen, according to the company.

Perfect color mixing takes place in the LED package itself thanks to the specially developed encapsulation material. Color appearance remains constant across the entire viewing angle, and the picture appears vibrant even when viewed off-axis. The beam angle of the LED is ±60°. Ambient light cannot ruin the picture quality because it is barely reflected by the black package in which the LED is housed.

Inside the LED are a red, a blue and a green chip fabricated using proprietary ThinFilm and ThinGaN technology. If the RGB LED is operated with a current of 20 mA, the individual chips produce typical luminous intensities of 250 mcd (red), 350 mcd (green) and 70 mcd (blue). Typical efficiency of this luminous intensity is 4 cd/W, which corresponds to a luminous efficacy of 12 lm/W.
