OPTICAL SOURCE ASSEMBLY AND TOUCH SCREEN DEVICE HAVING THE SAME

摘要

PURPOSE: A light source assembly and a touch screen device including the same are provided to increase the reliability of object recognition through uniformity improvement. CONSTITUTION: A first light source(71) emits light within a first wave length range. A second light source(72) emits light within a second wave length range. An optical member(60) receives the emission light of the first and second light sources. The reflectivity of the second light is greater than the reflectivity of the first light about the optical member. The first wave length range includes visible ray wavelength range. The second wavelength range includes an infrared wavelength range.
