The image data signal is output to the pixel unit of the display area 110; when the scan driving circuit 60 is the second reverse shift and the scan signal is output to the display area 110 through the scan line, the data driving circuit 50 is the first reverse Shift and shift through the data line and The processed image data signal is output to the pixel unit of the display area 110 corresponding to the scan signal.
下面以一幅影像顯示為例，說明顯示面板10正向設置以及倒置設置於顯示裝置1時，資料驅動電路50與掃描驅動電路60控制該顯示面板10正向顯示該幅影像之原理。 In the following, an image display is taken as an example to illustrate the principle that the data driving circuit 50 and the scanning driving circuit 60 control the display panel 10 to display the image in the forward direction when the display panel 10 is disposed in the forward direction and is disposed upside down on the display device 1.
請參閱圖6，當顯示面板10正向設置於顯示裝置1時，資料驅動電路50之第一移位方向控制端SHL為H，且第一資料觸發端S1DIO1有效，則待顯示的影像資料自第一資料驅動單元S1之DIO1端輸入，並由該第一資料驅動單元S1正向移位至第n位資料驅動單元Sn，且通過相應之資料線將移位並處理後之影像資料輸出至顯示區110；同時，掃描驅動電路60之第二移位方向控制端為L，且第一掃描觸發端STV1有效，則掃描驅動電路60從第一掃描驅動單元G1開始啟動掃描訊號，並該掃描訊號由第一掃描驅動單元G1正向移位至第m位掃描驅動單元Gm，且經過移位處理後之掃描訊號通過掃描線輸出至顯示區110並選中相應之像素單元，對應選中之像素單元，資料驅動電路50輸出相應正向移位處理後之影像資料訊號，並通過顯示區110之像素單元正向顯示該影像。 Referring to FIG. 6 , when the display panel 10 is disposed in the display device 1 , the first shift direction control end SHL of the data driving circuit 50 is H, and the first data trigger terminal S 1 DIO1 is valid, and the image to be displayed is displayed. after the data from the first data driving unit input terminal DIO1 of the S 1 by the first data driving unit S 1 forward shift n-bit data to the second drive unit S n, and the shifted and processed by the corresponding data line the image data output to the display area 110; the same time, the scan driver circuit 60, a second shift direction control terminal is L, and the first end STV1 scan trigger is valid, the scan driving circuit 60 from the first scan driving unit G 1 started scan signal, and the shift from the first scan signal scan driving unit G 1 to m-th bit forward scan driving unit G m, and the scan signal through the shifting process to the display area selected by the scanning lines 110 and the corresponding The pixel unit corresponds to the selected pixel unit, and the data driving circuit 50 outputs the image data signal corresponding to the forward shift processing, and displays the image in the forward direction through the pixel unit of the display area 110.
請參閱圖7，在此，需聲明係該幅輸出至資料驅動電路50的影像資料順序不變。當顯示面板10倒置設置於顯示裝置1時，資料驅動電路50的第一移位方向控制端SHL為L，且第二資料觸發端SNDIO2有效，則待顯示之影像資料自第n資料驅動單元Sn之DIO2端輸入，並自該第n資料驅動單元Sn反向移位至第一資料驅動單元S1，且通過相應之資料線將移位並處理後之影像資料輸出至顯示區110；同時，掃描驅動電路60的第二移位方向控制端U-D為H，第二掃描觸發端STV2有 效，則掃描驅動電路60從第m掃描驅動單元Gm開始啟動輸出掃描訊號，並由第m掃描驅動單元Gm反向移位至第一掃描驅動單元G1，且經過移位並處理後之掃描訊號通過掃描線輸出至顯示區110並選中相應的像素單元，對應選中之像素單元，資料驅動電路50輸出相應反向移位並處理後之影像資料訊號，並通過顯示區110之像素單元顯示影像。因為，在顯示面板10倒置設置後，該幅影像相對於顯示面板10正向設置時顯示區110內之像素單元之驅動順序以及影像之顯示順序依然相同，所以當該顯示面板10倒置設置後其依然顯示正向影像。 Referring to FIG. 7, it is to be noted that the order of the image data outputted to the data driving circuit 50 is unchanged. When the display panel 10 is disposed upside down on the display device 1, the first shift direction control terminal SHL of the data driving circuit 50 is L, and the second data trigger terminal S N DIO2 is valid, and the image data to be displayed is driven from the nth data. The DIO2 terminal of the unit S n is input, and is reversely shifted from the nth data driving unit S n to the first data driving unit S 1 , and the shifted and processed image data is output to the display area through the corresponding data line. At the same time, the second shift direction control terminal UD of the scan driving circuit 60 is H, and the second scan trigger terminal STV2 is valid, then the scan driving circuit 60 starts to output the scan signal from the mth scan driving unit G m , and is The m scan driving unit G m is reversely shifted to the first scan driving unit G 1 , and the shifted and processed scan signal is output to the display area 110 through the scan line and the corresponding pixel unit is selected, corresponding to the selected pixel. The unit, the data driving circuit 50 outputs the corresponding reverse-shifted and processed image data signal, and displays the image through the pixel unit of the display area 110. Because, after the display panel 10 is inverted, the driving order of the pixel units in the display area 110 and the display order of the images are still the same when the image is disposed in the forward direction of the display panel 10, so when the display panel 10 is inverted, Still positive image is displayed.
