LIGHT SOURCE MODULE AND IMAGE PROJECTION DEVICE |
| 摘要 |
A light source module and an image projection device which can have high resolution and high optical efficiency are provided with a simple optical system. A light source module includes a light source unit formed by a plurality of stacked light emission surfaces which emit lights of at least red, blue, and green wavelength bands, and a light-source drive and control unit which supplies a driving current to the respective light emission surfaces of the light source unit. Each of the light emission surfaces of the light source unit has a nanostructure smaller than a wavelength of visible light near a p-n junction provided in a semiconductor having a larger band gap than the visible light, and emits a light of a corresponding one of the wavelength bands via a phonon level. |
