本發明係相關於一種顯示面板之驅動方法、顯示面板及閘極驅動電路，尤指一種可改善畫素充電差異之顯示面板之驅動方法、顯示面板及閘極驅動電路。The invention relates to a driving method of a display panel, a display panel and a gate driving circuit, in particular to a driving method of a display panel, a display panel and a gate driving circuit which can improve pixel charging difference.

一般而言，液晶顯示面板包含有複數個畫素、閘極驅動電路以及源極驅動電路。源極驅動電路係用以寫入資料訊號於被開啟之畫素。閘極驅動電路包含複數級移位暫存器，用來提供複數個閘極訊號以控制畫素之開啟與關閉。Generally, a liquid crystal display panel includes a plurality of pixels, a gate driving circuit, and a source driving circuit. The source driver circuit is used to write a data signal to the pixel that is turned on. The gate drive circuit includes a plurality of shift register registers for providing a plurality of gate signals to control the turning on and off of the pixels.

請參考第1圖，第1圖為習知二列極性反轉(2-row inversion)方式驅動液晶顯示面板時相關波形的示意圖。如第1圖所示，於畫面顯示周期之第一掃描時段t1，閘極訊號S1先從第一電壓位準V1上拉至第二電壓位準V2，以開啟第一列畫素之電晶體，而資料訊號Sd被寫入被開啟之第一列畫素。之後，於畫面顯示周期之第二掃描時段t2，閘極訊號S2亦從第一電壓位準V1上拉至第二電壓位準V2，以開啟第二列畫素之電晶體，而資料訊號Sd再被寫入被開啟之第二列畫素。其中寫入第一列畫素及第二列畫素之資料訊號Sd的極性相同，而寫入下二列畫素之資料訊號的極性係相反於寫入第一列畫素及第二列畫素之資料訊號的極性，以此類推。Please refer to FIG. 1 , which is a schematic diagram of related waveforms when a liquid crystal display panel is driven by a conventional 2-row inversion method. As shown in FIG. 1, in the first scanning period t1 of the screen display period, the gate signal S1 is first pulled up from the first voltage level V1 to the second voltage level V2 to turn on the first column of pixels. And the data signal Sd is written to the first column of pixels that are turned on. Then, in the second scanning period t2 of the screen display period, the gate signal S2 is also pulled up from the first voltage level V1 to the second voltage level V2 to turn on the transistor of the second column of pixels, and the data signal Sd It is then written to the second column of pixels that are turned on.

The polarity of the data signal, and so on.

在上述二列極性反轉方式中，當第一列畫素剛被開啟時，資料訊號Sd尚未達到預定電壓位準，而當第二列畫素被開啟時，資料訊號Sd已達到預定電壓位準，因此，第一列畫素及第二列畫素之間會有充電差異，進而影響液晶顯示面板的畫面品質。尤其當液晶顯示面板的畫面更新頻率越高時，畫素的充電時間越短，因極性反轉驅動方式所造成的畫素充電差異問題將會更嚴重。In the above two-column polarity inversion mode, when the first column of pixels is turned on, the data signal Sd has not reached the predetermined voltage level, and when the second column of pixels is turned on, the data signal Sd has reached the predetermined voltage level. Therefore, there is a difference in charging between the first column of pixels and the second column of pixels, which in turn affects the picture quality of the liquid crystal display panel. Especially when the picture update frequency of the liquid crystal display panel is higher, the charging time of the pixel is shorter, and the difference in pixel charging caused by the polarity inversion driving method will be more serious.

When the present invention drives the liquid crystal display panel 100 in a two-column polarity inversion manner, as shown in FIG. 4, at the first scan period t1 of the picture display period, the first shift register 122 of the first stage outputs The first gate signal Sg1 is first pulled up from the first voltage level V1 to the second voltage level V2 to turn on the transistor T of the first column of pixels P via the scan line G1, and the data signal Sd1 having the first polarity The first column of pixels P that is turned on is written. Then, in the second scan period t2 of the picture display period, the second gate signal Sg2 outputted by the second shift register 124 of the second stage is pulled up from the third voltage level V3 to the fourth voltage level V4. The transistor T of the second column of pixels P is turned on via the scan line G2, and the data signal Sd1 having the first polarity is written to the second column of pixels P that is turned on. The fourth voltage level V4 is lower than the second voltage level V2, and the third voltage level V3 is lower than the first voltage level V1.

如第5圖所示，於畫面顯示周期之第三掃描時段t3，位於第3級之第一移位暫存器122輸出的第一閘極訊號Sg1先從第一電壓位準V1上拉至第二電壓位準V2，以經由掃描線G3開啟第三列畫素P之電晶體T，而具 第二極性之資料訊號Sd2被寫入被開啟之第三列畫素P。之後，於畫面顯示周期之第四掃描時段t4，位於第4級之第二移位暫存器124輸出的第二閘極訊號Sg2從第三電壓位準V3上拉至第四電壓位準V4，以經由掃描線G4開啟第四列畫素P之電晶體T，而具第二極性之資料訊號Sd2被寫入被開啟之第四列之畫素P，以此類推。其中第二極性係相反於該第一極性。As shown in FIG. 5, the first gate signal Sg1 outputted by the first shift register 122 at the third stage is first pulled from the first voltage level V1 to the third scan period t3 of the picture display period. a second voltage level V2 to turn on the transistor T of the third column of pixels P via the scan line G3 The data signal Sd2 of the second polarity is written to the third column of pixels P that is turned on.

依據上述配置，當本發明顯示面板100係以二列極性反轉(2-row inversion)方式驅動時，相鄰兩列畫素之第一列畫素P的電晶體T係被具較高電壓位準的第一閘極訊號Sg1開啟，以縮短資料訊號寫入的時間，因此相鄰兩列畫素之第一列畫素及第二列畫素之間的充電差異將會減少。According to the above configuration, when the display panel 100 of the present invention is driven in a two-row inversion manner, the transistor T of the first column of pixels of the adjacent two columns of pixels is subjected to a higher voltage. The level of the first gate signal Sg1 is turned on to shorten the time of writing the data signal, so the difference in charging between the first column of pixels and the second column of pixels of the adjacent two columns of pixels will be reduced.

另外，為了避免顯示面板100的饋通(feed through)效應，第二電壓位準V2及第一電壓位準V1之電壓差係相同於第四電壓位準V4及第三電壓位準V3之電壓差。In addition, in order to avoid the feed through effect of the display panel 100, the voltage difference between the second voltage level V2 and the first voltage level V1 is the same as the voltage of the fourth voltage level V4 and the third voltage level V3. difference.

在上述實施例中，本發明顯示面板之驅動方法係應用於二列極性反轉方式，然而，在本發明其他實施例中，本發明顯示面板之驅動方法亦可應用於其他極性反轉方式，例如二點極性反轉(2-dot inversion)方式。或者，本發明顯示面板之驅動方法亦可應用於如第7圖所示之二列加一極性反轉方式，以及應用於如第8圖所示之二點加一極性反轉方式。In the above embodiment, the driving method of the display panel of the present invention is applied to the two-column polarity inversion mode. However, in other embodiments of the present invention, the driving method of the display panel of the present invention can also be applied to other polarity inversion modes.
