Abstract
Abstract In an image display device, on the basis of a relation between power consumption measured at the time of power saving and an applied voltage at the time of releasing the power saving and a relation between the applied time and a rise time of an image, the applied voltage and time to a heater for realizing a power consumption and a rise time required to each mode are calculated. Based on the results, a duty of the switched voltage or a DC voltage level is controlled, and when the power saving is released, a voltage higher than the heater voltage at a normal display is applied for the calculated time cycle.
