<p>A display device is provided that includes a light source (17) for emitting a light, an image forming unit (14) for forming an image using the emitted light and an inputted image signal, and a projection lens (16) for projecting the formed image on a screen (12). The display device may further include an actuator (11) for shifting the image displayed on the screen, a temperature sensor (9) for detecting an ambient temperature around the actuator, and a controller (8) for driving the actuator according to the detected temperature.
The influence of temperature on the actuator is thus minimized and the actuator can increase the resolution of the display device stably by shifting the displaying locations of subsequent images (pixel-shifting).</p> |
