本揭示內容關於一種顯示裝置，特別是用以根據資料訊號及掃描訊號以驅動畫素電路之裝置。 The present disclosure relates to a display device, especially a device for driving a pixel circuit according to a data signal and a scanning signal.

平面顯示器因為具有高品質的影像顯示能力與低耗能之特性，而成為最普及的一種顯示裝置。基於製作成本的考量，顯示裝置的顯示面板中常會設置多工器以及驅動電路(例如：驅動IC)配合操作，使得驅動電路上的傳輸通道可以減少，同時，驅動電路的尺寸亦能因此而縮減。 The flat panel display has become the most popular display device because of its high-quality image display capability and low energy consumption. Due to manufacturing cost considerations, multiplexers and driver circuits (eg, driver ICs) are often provided in the display panel of the display device to cooperate with each other, so that the transmission channel on the driver circuit can be reduced, and the size of the driver circuit can be reduced accordingly. .

一般而言，顯示面板中的畫素可藉由不同的極性反轉方式來進行驅動，且多工器會依據相應的驅動方式交替地接收不同極性的操作電壓。因此，多工器的驅動方式，對於顯示面板的顯示品質有著最直接的影響。 Generally speaking, the pixels in the display panel can be driven by different polarity inversion methods, and the multiplexer will alternately receive operating voltages of different polarities according to the corresponding driving methods. Therefore, the driving method of the multiplexer has the most direct influence on the display quality of the display panel.

The first driving switch of the pixel circuit is used to selectively conduct according to the corresponding control signal. The second driving switch of the pixel circuit is used to selectively conduct according to the corresponding scan signal.

請參閱第1圖所示，係根據本揭示內容之部分實施例所繪示之顯示裝置100示意圖。在部分實施例中，顯示裝置100包含顯示面板110及至少一個多工器120。顯示面板110包含複數條資料線DL、複數條掃描線GL及複數個畫素電路200。畫素電路200係以陣列方式排列於顯示區域111內。顯示裝置100用以根據影像資料，產生複數個資料訊號Sd1~Sd3及複數個掃描訊號Sg1~Sgn，並透過資料線DL及掃描線GL，傳送資料訊號Sd1~Sd3及掃描訊號Sg1~Sgn給畫素電路200，以驅動畫素電路200顯示出影像畫面。 Please refer to FIG. 1, which is a schematic diagram of a display device 100 according to some embodiments of the present disclosure. In some embodiments, the display device 100 includes a display panel 110 and at least one multiplexer 120. The display panel 110 includes a plurality of data lines DL, a plurality of scan lines GL, and a plurality of pixel circuits 200. The pixel circuits 200 are arranged in the display area 111 in an array. The display device 100 is used to generate a plurality of data signals Sd1~Sd3 and a plurality of scan signals Sg1~Sgn according to the image data, and transmit the data signals Sd1~Sd3 and the scan signals Sg1~Sgn to the picture through the data line DL and the scan line GL The pixel circuit 200 drives the pixel circuit 200 to display an image frame.

在部分實施例中，顯示裝置100更包含控制電路130、源極驅動器131及掃描驅動器132。控制電路130用以根據影像資料來驅動源極驅動器131及掃描驅動器132，使源極驅動器131發送資料訊號Sd1~Sd3、掃描驅動器132發送掃描訊號Sg1~Sgn。為使圖式簡潔，在第1圖中僅繪示出源極驅動器131的一個輸出端，並用以示意說明顯示裝置100的運作方式，但在其他實施例中，顯示裝置100可具有複數個多工器120，且源極驅動器131可具有複數個輸出端。 In some embodiments, the display device 100 further includes a control circuit 130, a source driver 131, and a scan driver 132. The control circuit 130 is used to drive the source driver 131 and the scan driver 132 according to the image data, so that the source driver 131 sends data signals Sd1~Sd3, and the scan driver 132 sends scan signals Sg1~Sgn. In order to simplify the drawing, only one output terminal of the source driver 131 is shown in the first drawing, and is used to schematically illustrate the operation mode of the display device 100, but in other embodiments, the display device 100 may have a plurality of The tool 120 and the source driver 131 may have a plurality of output terminals.

多工器120設置於顯示面板110上鄰近於顯示區域111的位置，用以傳遞資料訊號Sd1~Sd3至資料線DL。如第1圖所示，源極驅動器131的一個輸出端透過多工器120對應至複數條條資料線DL，多工器120包含複數個切換開關121，每個切換開關121用以導通一條資料線DL，用以驅動同一直列的畫素電路200。在本實施例中，多工器120包含三個切換開關121，分別對應於一條資料線DL。切換開關121相對應之資料線DL用以分別傳遞紅色畫素資料訊號、綠色畫素資料訊號及藍色畫素資料訊號，該些畫素資料訊號能組成視覺效果上的一個畫素點。在其他實施例中，源極驅動器131中切換開關121的數量可任意調整，例如：四個切換開關121，分別透過資料線DL傳遞紅色、藍色、綠色及黃色的畫素資料。 The multiplexer 120 is disposed on the display panel 110 adjacent to the display area 111 for transmitting data signals Sd1~Sd3 to the data line DL. As shown in FIG. 1, one output end of the source driver 131 corresponds to a plurality of data lines DL through a multiplexer 120, and the multiplexer 120 includes a plurality of cuts For the switch 121, each switch 121 is used to turn on a data line DL to drive the pixel circuit 200 in the same row. In this embodiment, the multiplexer 120 includes three changeover switches 121, each corresponding to a data line DL. The data line DL corresponding to the switch 121 is used to transmit the red pixel data signal, the green pixel data signal and the blue pixel data signal, respectively, and these pixel data signals can form a pixel point on the visual effect. In other embodiments, the number of the switch 121 in the source driver 131 can be adjusted arbitrarily, for example: four switch 121, respectively transmitting red, blue, green and yellow pixel data through the data line DL.

在部分實施例中，多工器120用以依序接收控制訊號MUX1~MUX3，以依序開啟各個切換開關121，且依序將資料訊號Sd1~Sd3傳遞至對應之資料線DL。對應於同一條資料線DL的畫素電路200(即，同一直列之畫素電路200)用以接收相應的該控制訊號MUX1~MUX3，以選擇性地傳輸相應的資料訊號Sd1~Sd3至畫素電路200。 In some embodiments, the multiplexer 120 is used to receive the control signals MUX1~MUX3 in sequence, turn on each switch 121 in sequence, and sequentially transmit the data signals Sd1~Sd3 to the corresponding data line DL. The pixel circuit 200 corresponding to the same data line DL (ie, the same pixel circuit 200 in the same row) is used to receive the corresponding control signals MUX1~MUX3 to selectively transmit the corresponding data signals Sd1~Sd3 to the pixels Circuit 200.

請參閱第1及2圖所示，在部分實施例中，切換開關121之控制端121a電性連接於控制電路130，以接收控制訊號MUX1~MUX3。切換開關121之第一端121b電性連接於源極驅動器131，以接收資料訊號Sd1~Sd3。切換開關121之第二端121c則電性連接到資料線DL。如此，當控制訊號MUX1~MUX3為致能訊號時，切換開關121將可導通，以將資料訊號Sd1~Sd3傳遞至同一直列的畫素電路200。此外，在部分實施例中，多工器120更包含複數條控制線CL，控制線CL分別對應於資料線DL，其第一端用以接收控制訊號MUX1~MUX3，其第二端則電性連接至同一直列之畫素電路200的驅動開關。以在控制控制訊號MUX1~MUX3為致能訊號時，對應之切換開關121以及對應之畫素電路200內的至少一個驅動開關將一併被致能，進而傳輸資料訊號Sd1~Sd3至畫素電路200內之電容器，以發出預期之光亮。 Please refer to FIGS. 1 and 2. In some embodiments, the control terminal 121 a of the switch 121 is electrically connected to the control circuit 130 to receive the control signals MUX1~MUX3. The first end 121b of the switch 121 is electrically connected to the source driver 131 to receive the data signals Sd1~Sd3. The second end 121c of the switch 121 is electrically connected to the data line DL. In this way, when the control signals MUX1~MUX3 are enable signals, the switch 121 can be turned on to transmit the data signals Sd1~Sd3 to the pixel circuits 200 in the same line. In addition, in some embodiments, the multiplexer 120 further includes a plurality of control lines CL, the control lines CL respectively correspond to the data lines DL, and the first end is used to Receiving the control signals MUX1~MUX3, the second end is electrically connected to the driving switch of the pixel circuit 200 in the same line. When the control signals MUX1~MUX3 are enabled signals, the corresponding switch 121 and at least one drive switch in the corresponding pixel circuit 200 will be enabled together, and then transmit the data signals Sd1~Sd3 to the pixel circuit The capacitor within 200 emits the expected light.

本揭示內容之顯示裝置100能透過多工器120依序開啟各個切換開關121，且在開啟切換開關121時，同時導通同一直列的畫素電路200中的至少一個驅動開關，如此，將能提升顯示面板110之整體顯示品質。 The display device 100 of the present disclosure can sequentially turn on each switch 121 through the multiplexer 120, and when the switch 121 is turned on, at least one driving switch in the same pixel circuit 200 at the same time is turned on, so that it can be improved The overall display quality of the display panel 110.

請參閱第3圖所示，係本揭示內容之部分實施例中，顯示裝置100的運作時序圖。傳統的驅動方法，是在一個週期中，依序發送掃描訊號Sg1~Sgn，以驅動每一橫排的畫素電路200。在驅動每一橫排的畫素電路200的期間，會再依序開啟各切換開關121。然而，由於多工器120具有大負載，因此在反覆開啟、關閉的過程中，將會使得資料線DL上充電、放電的速度受到影響。如第3及4圖所示，在本實施例中，係透過多工器120在一個幀週期F中透過控制訊號MUX1~MUX3依序開啟各切換開關121，同時驅動同一直列的畫素電路200。接著，在發送控制訊號MUX1~MUX3的期間，再依序發送掃描訊號Sg1~Sgn。如此，由於每個切換開關121開啟及關閉的次數較少，因此能避免切換開關121之負載效應對於資料線DL充電速度的影響，從而提升了顯示裝置100的顯示品質。 Please refer to FIG. 3, which is an operation timing diagram of the display device 100 in some embodiments of the present disclosure. The traditional driving method is to sequentially send the scanning signals Sg1~Sgn in one cycle to drive each horizontal pixel circuit 200. During driving of each horizontal row of pixel circuits 200, each switch 121 is turned on sequentially. However, since the multiplexer 120 has a large load, the speed of charging and discharging on the data line DL will be affected during the repeated opening and closing process. As shown in FIGS. 3 and 4, in this embodiment, the multiplexer 120 sequentially turns on each switch 121 through the control signals MUX1~MUX3 in a frame period F, and drives the pixel circuits 200 in the same row . Then, during the period when the control signals MUX1~MUX3 are sent, the scan signals Sg1~Sgn are sent in sequence. In this way, since the number of times that each switch 121 is turned on and off is less, the effect of the load effect of the switch 121 on the charging speed of the data line DL can be avoided, thereby improving the display quality of the display device 100.

請參閱第4圖所示，在部分實施例中，顯示裝置100的一個幀週期F更可區分為紅色顯示期間PR、綠色顯示期間PG及藍色顯示期間PB。舉例而言，當第4圖中最左方之切換開關121透過控制訊號MUX1而被導通時，此時顯示裝置100將處於紅色顯示期間PR，此時，掃描驅動器132將逐一發送掃描訊號Sg1~Sgn，使同一直列的畫素電路200產生出對應光亮。而其他直列之畫素電路200則將保持關閉。 Please refer to FIG. 4. In some embodiments, one frame period F of the display device 100 can be further divided into a red display period PR, a green display period PG, and a blue display period PB. For example, when the leftmost switch 121 in FIG. 4 is turned on through the control signal MUX1, the display device 100 will be in the red display period PR at this time, and the scan driver 132 will send the scan signals Sg1~ one by one. Sgn causes the pixel circuits 200 in the same row to generate corresponding light. The other in-line pixel circuits 200 will remain off.

請參閱第1~3圖所示，在部分實施例中，畫素電路200包含第一驅動開關T1、第二驅動開關T2及畫素電容C，驅動開關T1、T2可為電晶體開關，例如：薄膜電晶體(Thin-Film Transistor，TFT)，且畫素電容C可包含複數個相互並聯之電容器。該些畫素電路200的第一驅動開關T1用以根據相應的控制訊號MUX1~MUX3選擇性地導通，第二驅動開關T2用以根據相應的掃描訊號Sg1~Sgn選擇性地導通。當畫素電路200同時接收到控制訊號MUX1~MUX3及掃描訊號Sg1~Sgn時，即會被導通，而接收資料訊號Sd1~Sd3。 Please refer to FIGS. 1-3. In some embodiments, the pixel circuit 200 includes a first driving switch T1, a second driving switch T2, and a pixel capacitor C. The driving switches T1 and T2 may be transistor switches, for example : Thin-Film Transistor (TFT), and the pixel capacitor C may include a plurality of parallel capacitors. The first drive switches T1 of the pixel circuits 200 are used to be selectively turned on according to the corresponding control signals MUX1~MUX3, and the second drive switch T2 is used to be selectively turned on according to the corresponding scan signals Sg1~Sgn. When the pixel circuit 200 receives the control signals MUX1~MUX3 and the scanning signals Sg1~Sgn at the same time, it will be turned on and receive the data signals Sd1~Sd3.

承上，在部分實施例中，第一驅動開關T1之控制端電性連接於控制線CL，第二驅動開關T2的控制端則電性連接於掃描線GL。由於第一驅動開關T1及第二驅動開關T2的控制端分別接收不同的訊號(即，控制訊號MUX1~MUX3與掃描訊號Sg1~Sgn)，因此，能確保不同直列的畫素電路200中的驅動開關不會同時被導通。舉例而言，如第3及4圖所示，當紅色顯示期間PR時，控制訊號MUX1為致能訊號、控制訊號MUX2、MUX3為禁能訊號。因此，當掃描驅動器132向同一條掃描線GL發送掃描訊號Sg1時，仍只有對應於控制訊號MUX1的畫素電路200會被驅動，而接收資料訊號Sd1。 As mentioned above, in some embodiments, the control terminal of the first drive switch T1 is electrically connected to the control line CL, and the control terminal of the second drive switch T2 is electrically connected to the scan line GL. Since the control ends of the first driving switch T1 and the second driving switch T2 receive different signals (ie, the control signals MUX1~MUX3 and the scanning signals Sg1~Sgn), the driving in the pixel circuits 200 of different in-line can be ensured The switch will not be turned on at the same time. For example, As shown in Figures 3 and 4, when the PR is displayed in red, the control signal MUX1 is the enable signal, and the control signals MUX2 and MUX3 are the disable signals. Therefore, when the scan driver 132 sends the scan signal Sg1 to the same scan line GL, only the pixel circuit 200 corresponding to the control signal MUX1 will be driven and receive the data signal Sd1.

請參閱第2圖所示，在部分實施例中，畫素電路200之第二驅動開關T2串接於第一驅動開關T1及畫素電容C之間。而在其他部分實施例中，如第5圖所示，畫素電路200之第一驅動開關T1串接於第二驅動開關T2及畫素電容C之間。據此，由於被控制訊號MUX1~MUX3所控制之第一驅動電晶體T1被移動到畫素電路200中較內側的位置，因此，將能改善第一驅動電晶體T1的劣化(Stress)問題。 Please refer to FIG. 2. In some embodiments, the second driving switch T2 of the pixel circuit 200 is connected in series between the first driving switch T1 and the pixel capacitor C. In other embodiments, as shown in FIG. 5, the first driving switch T1 of the pixel circuit 200 is connected in series between the second driving switch T2 and the pixel capacitor C. According to this, since the first driving transistor T1 controlled by the control signals MUX1~MUX3 is moved to a position inside the pixel circuit 200, the stress problem of the first driving transistor T1 will be improved.

另外，請參閱第3圖所示，在部分實施例中，該些掃描訊號Sg1~Sgn之致能期間於時序上部分重疊。舉例而言，如第2圖所示，在部分實施例中，掃描訊號Sg1的後半段致能時間與掃描訊號Sg2的前半段致能時間相重疊。透過此一「重疊(Overlapping)」的驅動方式，將能使資料線DL有更充裕的時間進行充電，且將資料訊號Sd1~Sd3寫入至畫素電路200中。 In addition, please refer to FIG. 3, in some embodiments, the enable periods of the scan signals Sg1~Sgn partially overlap in timing. For example, as shown in FIG. 2, in some embodiments, the enabling time of the second half of the scanning signal Sg1 overlaps with the enabling time of the first half of the scanning signal Sg2. Through this "overlapping" driving method, the data line DL can be charged for more time, and the data signals Sd1~Sd3 are written into the pixel circuit 200.
