Abstract

A method for driving a display panel having plural pixel electrodes arranged in rows and columns is provided. The method includes: receiving display data in plural periods; converting the received display data into a source voltage signal for each of the pixel electrodes; and applying the respective source voltage signal to each of the pixel electrodes. Each of the periods includes plural frames consisting of plural non-skipped frames and at least one skip frame subsequent to the non-skipped frames. The polarity of the source voltage signal in the non-skipped frame directly preceding the skip frame of one period is opposite to the polarity of the source voltage signal in the non-skipped frame directly preceding the skip frame of subsequent period.

Claims (14)

1. A method for driving a display panel having a plurality of pixel electrodes arranged in rows and columns, comprising:

receiving display data in a plurality of periods;

converting the received display data into a source voltage signal for each of the pixel electrodes; and

applying the respective source voltage signal to each of the pixel electrodes;

wherein each of the periods comprises a plurality of frames consisting of a plurality of non-skipped frames and at least one skip frame subsequent to the non-skipped frames, where the skip frame is the frame without applying the source voltage signal to each of the pixel electrodes;

wherein a polarity of the source voltage signal in the non-skipped frame directly preceding the skip frame of one period is opposite to a polarity of the source voltage signal in the non-skipped frame directly preceding the skip frame of subsequent period.

2. The method of claim 1 , wherein polarities of the source voltage signal applied to each of the pixel electrodes in two consecutive non-skipped frames of each of the periods are opposite to each other.

3. A source driving module for driving a display panel having a plurality of pixel electrodes arranged in rows and columns, comprising:

a data storage unit configured to receive display data in a plurality of periods;

a data converting unit operatively coupled to the data storage unit and configured to convert the received display data into a source voltage signal for each of the pixel electrodes; and

a source driver operatively coupled to the data converting unit and configured to apply the respective source voltage signal to each of the pixel electrodes;

wherein each of the periods comprises a plurality of frames consisting of a plurality of non-skipped frames and at least one skip frame subsequent to the non-skipped frames, where the skip frame is the frame without applying the source voltage signal to each of the pixel electrodes;

wherein a polarity of the source voltage signal in the non-skipped frame directly preceding the skip frame of one period is opposite to a polarity of the source voltage signal in the non-skipped frame directly preceding the skip frame of subsequent period.

4. The source driving module of claim 3 , wherein polarities of the source voltage signal applied to each of the pixel electrodes in two consecutive non-skipped frames of each of the periods are opposite to each other.
