Abstract
In an image display apparatus, based upon such a relationship among previously measured power consumption in a power save mode, an application voltage and application time thereof, and also rising time of a screen when the power save mode is released, a heater application voltage and application time of this heater application voltage are calculated in order to realize power consumption and rising time, which are required with respect to each of modes. Based upon the calculation results, either a duty ratio of a switched voltage or application time of this heater application voltage are controlled. At the same time, when the power save mode is released, a higher voltage than the heater application voltage in the normal display mode is applied only for the calculated time period.
