Please refer to FIG. 1 and FIG. 2 at the same time for details of the driving method of the display device 100 in an embodiment. In detail, when the display device 100 operates in the time interval TGS1, the gate driver 130 can provide enabling (for example Is the high voltage level) gate drive signal GS1 (the remaining gate drive signals are disabled (for example, low voltage level) state) to the corresponding transistor, at the same time, the source driver 120 can provide a negative The source drive signals DS1 to DS5 of the grayscale voltage are transferred to the corresponding pixels. Moreover, the common voltage generator 140 can adjust the common voltage VCOM to the second voltage level V2 (for example, a high voltage level) according to the polarity of the gray-scale voltage.

Moreover, the common voltage generator 140 can adjust the common voltage VCOM to the first voltage level V1 (for example, a low voltage level) according to the polarity of the gray-scale voltage.

In addition, the common voltage generator 140 may change the common voltage VCOM to the first voltage level V1 (for example, a low voltage level) according to the polarity of the gray-scale voltage.

需注意到的是，當顯示裝置100操作於其餘的時間區間（如，時間區間TGS5～TGS8）時，源極驅動器120以及閘極驅動器130可根據於時間區間TGS51～TGS4時的驅動方式來驅動顯示面板110，並且共用電壓產生器140同樣可以依據灰階電壓的極性來調整共用電壓VCOM的電壓準位，在此恕不多贅述。It should be noted that when the display device 100 operates in the remaining time interval (for example, the time interval TGS5 to TGS8), the source driver 120 and the gate driver 130 can be driven according to the driving method during the time interval TGS51 to TGS4 The display panel 110 and the common voltage generator 140 can also adjust the voltage level of the common voltage VCOM according to the polarity of the gray-scale voltage, which will not be repeated here.

圖3是依照本新型創作另一實施例的顯示裝置100的驅動方法的波形圖。請同時參照圖1以及圖3，關於顯示裝置100在另一實施例中的驅動方式之說明細節，詳細來說，當顯示裝置100依序操作於時間區間TGS1～TGS13中的奇數標號時，閘極驅動器130可以依序提供致能（例如是高電壓準位）的閘極驅動信號GS1～GS13中的奇數標號至對應的電晶體，在此同時，源極驅動器120可以提供具有負極性灰階電壓的源極驅動信號DS1～DS5至對應的畫素中。並且，共用電壓產生器140可以依據灰階電壓的極性，以將共用電壓VCOM調整為第二電壓準位V2（例如是高電壓準位）。FIG. 3 is a waveform diagram of the driving method of the display device 100 according to another embodiment of the present invention. Please refer to FIG. 1 and FIG. 3 at the same time, for details of the driving method of the display device 100 in another embodiment. The pole driver 130 can sequentially provide odd numbers in the gate drive signals GS1 to GS13 that enable (for example, high voltage level) to the corresponding transistors. At the same time, the source driver 120 can provide gray scales with negative polarity The source driving signals DS1 to DS5 of the voltage go to the corresponding pixels. Moreover, the common voltage generator 140 can adjust the common voltage VCOM to the second voltage level V2 (for example, a high voltage level) according to the polarity of the gray-scale voltage.

另一方面，當顯示裝置100依序操作於時間區間TGS2～TGS12中的偶數標號時，閘極驅動器130可以依序提供致能（例如是高電壓準位）的閘極驅動信號GS2～GS12中的偶數標號至對應的電晶體，在此同時，源極驅動器120可以提供具有正極性灰階電壓的源極驅動信號DS1～DS5至對應的畫素中。並且，共用電壓產生器140可以依據灰階電壓的極性，以將共用電壓VCOM從第二電壓準位V2調整為第一電壓準位V1（例如是低電壓準位）。On the other hand, when the display device 100 is sequentially operated with even numbers in the time interval TGS2 to TGS12, the gate driver 130 may sequentially provide the gate drive signals GS2 to GS12 that are enabled (eg, high voltage level) To the corresponding transistors. At the same time, the source driver 120 can provide source driving signals DS1 to DS5 with positive gray-scale voltages to the corresponding pixels. Moreover, the common voltage generator 140 can adjust the common voltage VCOM from the second voltage level V2 to the first voltage level V1 (for example, a low voltage level) according to the polarity of the gray-scale voltage.

In this way, the common voltage generator 140 can reduce the number of transitions of the common voltage VCOM according to the polarity of the gray-scale voltage, thereby reducing the power consumption of the display device 100.

綜上所述，本新型創作的顯示裝置利用源極驅動器來使顯示面板中的第一列的顯示列與最後一列的顯示列的驅動極性互為相同，並使第一顯示列組與第二顯示列組的驅動極性互為互補，且分別使第一列的顯示列與最後一列的顯示列皆與相鄰的第一顯示列組的驅動極性互為互補。如此一來，顯示裝置可以在使用交流電壓來驅動各個顯示列以及最後顯示列中所對應的畫素的情況下，透過雙點極性反轉的驅動方式以有效地提升顯示畫面的品質。In summary, the display device created by the present invention utilizes a source driver to make the drive polarities of the first display column and the last display column of the display panel mutually the same, and to make the first display column group and the second display column The driving polarities of the display column groups are complementary to each other, and the display columns of the first column and the display column of the last column are complementary to the driving polarities of the adjacent first display column groups.
