Abstract:
A backlight system for a display device which comprises a light emitting diode comprising an encapsulating lens and an aspheric lens interposed between the light emitting diode and the display device. The backlight system provides a luminance of substantially 100K nits at a cone angle of substantially 12° and is of particular utility in conjunction with laser-based range and speed measurement instruments.
