MultiLEDs for LED video displays

Osram Opto Semiconductors is launching two MultiLEDs for LED video displays.

The MultiLEDs are targeted at high-resolution video display applications that require high brightness and high color fidelity from all viewing angles.

In addition, the jet black package version with a higher contrast level and depth of colour is ideal for indoor applications that are exposed to a wide dynamic range of ambient lighting, such as at a rock concert where the lighting can change quickly from ultra dark to the blinding flash of spotlights.

The MultiLED with black packaging offers particularly impressive contrast in video displays with a typical luminance of 2,000cd/m and a pixel spacing of 5 to 7mm.

The colour black appears on the display as a truly deep black, which gives pictures great depth and creates 3D effects.

The white point for the MultiLED in the white package is at 2,000mcd.

Both new versions are based on high-power chips featuring the latest Thinfilm and ThinGaN technology.

The MultiLEDs are manufactured in very narrow tolerances in terms of brightness and colour to ensure homogeneous screen display, and the display colours remain constant from all viewing angles.

These extremely bright multi-chip LEDs also benefit from their six-lead design, ensuring effective heat removal and enabling currents of 15mA per colour to be achieved, even at an ambient temperature of 85C.
