Abstract:
1. A liquid crystal projector comprising: a first temperature sensor, for sensing the ambient temperature of the main body of the liquid crystal projector; a second temperature sensor, for sensing the ambient temperature of a liquid crystal panel; means for shutting off the power to a light source lamp for backlight when a temperature sensed by the first temperature sensor is not less than a first shut-off temperature; means for shutting off the power to the light source lamp for backlight when a temperature sensed by the second temperature sensor is not less than a second shut-off temperature; and means for shutting off the power to the light source lamp for backlight when the difference between a temperature sensed by the first temperature sensor and a temperature sensed by the second temperature sensor is more than a predetermined value.
