Abstract: Provided are an optical module platform structure and a method of manufacturing the same. The optical module platform structure includes an optical module platform substrate, a light source device mounted on a light source mount attached on one upper side of the optical module platform substrate, a waveguide spaced apart from the light source device by a certain interval and mounted on a waveguide mount attached on the optical module platform substrate, a lens mount fixed between the light source mount and the waveguide mount, and a lens fixed to a top of the lens mount. Therefore, optical coupling efficiency between a light source and a waveguide is maximized by applying a lens mount, and an optical alignment error is minimized.

Abstract: A display device includes a display panel, and a depth perception adjusting unit for adjusting a depth perception, based on polarization characteristics of light output from the display panel, wherein the depth perception adjusting unit includes a directional mirror and a reflective polarizer. Thus, the display device is implemented such that the directional mirror transmits or reflects light depending on an advancing direction of the light. Accordingly, any crosstalk phenomenon does not occur, and a depth perception can be adjusted without any loss of brightness efficiency.
