DISPLAY DEVICE |
摘要 |
In a display device, a light amount of laser light directed from an optical filter to a combiner is controlled through control of a temperature of a light source using temperature dependence of a wavelength of the light source. Further, in the display device, since the adjustment of the light amount is performed using the temperature dependence of the wavelength of the light source instead of adjusting a power supply voltage of the light source. |

1. A display device, comprising:
an optical scanning device including a light source that outputs light, an optical scanning unit that scans the output light from the light source, and an optical filter arranged on an optical path of the output light; a display onto which the output light scanned by the optical scanning device is projected, with the output light superimposed on a background; and a temperature control unit that controls a temperature of the optical scanning device and controls a light amount of the output light directed from the optical filter to the display. |
