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.

Abstract: A method for driving a liquid crystal display device is disclosed. When data clock (DCLK) is not required, the method of driving a liquid crystal display device with low power consumption enables the close loop of the DCLK. That is, after a data transmission (LOAD) signal is triggered and before a data reception (DSTH) signal is triggered, the timing controller forces the DCLK signal to be at a low voltage level, which means the DCLK signal is not outputted, and therefore power saving is achieved.

In order to drive polarity inversion of electrodes of the LCD panel, a polarity inverting signal is provided and a digital video data is outputted, wherein the polarity inverting signal has a frequency higher than a scan frequency of scan lines but lower than a display frequency of sub-pixels. Then, the digital video data is converted into an analog video data. The analog video data has a polarity inverting frequency substantially equal to the frequency of the polarity inverting signal.

Abstract: An method for the partial display mode monitor, which is suitable for the monitor operation in the partial mode. In this method, the memory is first planned so that each pixel has one corresponding memory address in a plurality of memory addresses within the planned memory. A serial controller is used to detect and determine whether the original pattern in the display screen has been updated or not, wherein the original pattern is stored in the memory and also comprises some pixels which have corresponding memory addresses. Then, when the serial controller detects that the original pattern has updated to a new pattern, the new pattern is compared with the original pattern, so as to replace the original pattern, which is stored in the memory and its corresponding memory addresses, with the new pattern. Finally, the new pattern is output to the monitor.
