Abstract: A display driving apparatus applied to a panel. The panel displays a first image with a first refresh rate. A first refresh cycle corresponding to the first refresh rate includes a refresh period and at least one non-refresh period. The display driving apparatus includes a real-time determination module and a data processing module. The real-time determination module is coupled to the panel and used to immediately determine whether the panel wants to replace the originally displayed first image with a second image during the first refresh cycle. The data processing module is coupled to the real-time determination module and the panel. If a determination result of the real-time determination module is yes, the data processing module immediately controls the panel to start to display the second image at a first time during the first refresh cycle.

The power supply is coupled to the display panel. The dynamic voltage controller includes a data analyzing module and a voltage control module. The data analyzing module receives and analyzes an image data to obtain a maximum brightness, an average brightness and an average current to further estimate a minimum driving voltage needed for the display panel to display the image data. The voltage control module coupled between the data analyzing module and power supply is used to output a voltage control signal to the power supply according to the minimum driving voltage, so that the power supply is controlled by the voltage control signal to output the minimum driving voltage to the display panel to drive the display panel to display the image data.

Abstract: A low power driving method for a display panel and a driving circuit therefor. When the voltage of a corresponding common electrode of a pixel in a pixel array is changed from one of the first voltage and the second voltage to the other thereof according to a polarity signal, the voltage of the corresponding pixel electrode of the pixel is driven. In an embodiment, a data code for the pixel and the polarity signal are utilized to predict a trend of the corresponding target voltage of the data code, and the voltage of the pixel electrode or the data line is changed to a voltage close to the target voltage of the pixel according to the prediction result. Thus, the swing range of the voltage of the data line can be efficiently reduced, and power saving and reduction in transition time can also be achieved.

The regulator circuit includes a signal output end. The first switch circuit is turned on in response to an enabled first control signal such that the first frequency compensation circuit is coupled to the regulator circuit. The detection circuit determines whether an output capacitor is coupled to the signal output end, and generates the enabled first control signal to turn on the first switch circuit and connect the first frequency compensation circuit to the regulator circuit when the output capacitor is not coupled to the signal output end. Therefore, the regulator circuit is frequency compensated by the first frequency compensation circuit.
