Image display device |
摘要 |
An image display device includes a laser source for emitting a laser beam, an image forming element which uses the laser beam to emit image light for displaying an image, a first diffraction element for diffracting the image light, and a controller for controlling a display position of the image on the basis of a wavelength of the laser beam and a temperature of the first diffraction element. |

1. An image display device comprising:
a laser source configured to emit a laser beam; an image forming element which uses the laser beam to emit image light for displaying an image; a first diffraction element configured to diffract the image light; a controller configured to control a display position of the image in response to a wavelength of the laser beam and a temperature of the first diffraction element; a first thermometer which measures at least one of a temperature of the laser source and a temperature around the laser source to output first temperature data; and a second thermometer which measures at least one of a temperature of the first diffraction element and a temperature around the first diffraction element to output second temperature data, wherein the controller controls the display position of the image in response to the first and second temperature data. |
