DUAL LIGHT SOURCE SYSTEM AND METHOD OF GENERATING DUAL IMAGES USING THE SAME

摘要

A dual light source system is adapted to be disposed in a display region of a display device and includes first and second light sources. The first light source includes a plurality of first packaging units each including at least one first LED element and is configured to emit a plurality of visible lights having different wavelengths within a first wavelength range to generate a first image. The second light source is configured to emit a plurality of invisible lights within a second wavelength range to generate a second image without interfering with the first image and includes a plurality of spaced-apart second packaging units each including at least one second LED element. A method of generating dual images is also disclosed.
