    Abstract: A display control device and a display control method for use in a portable electronic apparatus are disclosed. The portable electronic apparatus includes a main controller and a display panel. The display control device includes a digital data register in communication with the main controller for storing a digital data display signal received from the main controller, and a digital-to-analog converter in communication with the digital data register, converting the digital data display signal stored in the digital data register into an analog data display signal and outputting the analog data display signal to the display panel to be revealed. The main controller keeps on outputting refreshed digital data display signals in a normal mode, and suspends the output of any further digital data display signal in an idle mode. In the idle mode, the digital data register reiteratively outputs a last stored digital data display signal to the digital-to-analog converter.
