A packaged RGB laser module is demonstrated. Its size reaches as small as 8x4x3 mm. A compact RGB laser scanning module is also demonstrated. Since the modules are based on the waveguide-type combiner, each combined output beam is perfectly aligned. Clear full-color high-definition video images are obtained by using them.
