Abstract
An optical sensor device and a packaging method thereof are disclosed. The optical filter structure includes a light-emitting module, a first structure, a second structure and a mask layer. The first and second structures are formed on opposing ends of light-emitting module and cover portions of light-emitting module. The light-emitting module includes a light exit region, a photosensitive member and an optical filter layer. The light exit region and photosensitive member are both located on a side of light-emitting module close to first structure, the first structure exposes light exit region and photosensitive member. The optical filter layer wraps exposed portion of photosensitive member. The mask layer is arranged on first structure and surface of light-emitting module facing first structure, and the mask layer exposes light exit region and photosensitive member, avoiding influence of external light on optical sensor device through mask layer.
