相對的，在多工器MUX2_2（亦稱為第二多工器）中，多工器MUX2_2的開關SW1耦接於資料端ST2（亦稱為第二資料端）與資料線D2之間，並且多工器MUX2_2的開關SW1亦可依據驅動器120所提供的控制信號SC1而被導通或斷開。換言之，當顯示裝置100操作於畫素充電期間且控制信號SC1被設定為致能狀態時，多工器MUX2_2可依據開關SW1的導通路徑，以提供畫素電壓至對應的顯示畫素N1_1～N3_1（亦稱為第二顯示畫素）。In contrast, in the multiplexer MUX2_2 (also called the second multiplexer), the switch SW1 of the multiplexer MUX2_2 is coupled between the data terminal ST2 (also called the second data terminal) and the data line D2, and The switch SW1 of the multiplexer MUX2_2 can also be turned on or off according to the control signal SC1 provided by the driver 120.

另一方面，多工器MUX2_2的開關SW2耦接於資料端ST2與資料線D4之間，並且多工器MUX2_2的開關SW2亦可依據驅動器120所提供的控制信號SC2而被導通或斷開。換言之，當顯示裝置100操作於畫素充電期間且控制信號SC2被設定為致能狀態時，多工器MUX2_2可依據開關SW2的導通路徑，以提供畫素電壓至對應的顯示畫素N1_2～N3_2（亦稱為第二顯示畫素）。On the other hand, the switch SW2 of the multiplexer MUX2_2 is coupled between the data terminal ST2 and the data line D4, and the switch SW2 of the multiplexer MUX2_2 can also be turned on or off according to the control signal SC2 provided by the driver 120. In other words, when the display device 100 is operating during the pixel charging period and the control signal SC2 is set to the enabled state, the multiplexer MUX2_2 can provide pixel voltages to the corresponding display pixels N1_2 to N3_2 according to the conduction path of the switch SW2 (Also known as the second display pixel).

值得一提的是，在顯示面板110中，各個顯示畫素P1_1～P3_1以及顯示畫素P1_2～P3_2分別具有第一顯示極性（例如是正的顯示極性），且各個顯示畫素N1_1～N3_1以及顯示畫素N1_2～N3_2分別具有第二顯示極性（例如是負的顯示極性）。其中，所述第一顯示極性與第二顯示極性互為相反。It is worth mentioning that in the display panel 110, each of the display pixels P1_1 to P3_1 and the display pixels P1_2 to P3_2 has a first display polarity (for example, a positive display polarity), and each of the display pixels N1_1 to N3_1 and the display The pixels N1_2 to N3_2 each have a second display polarity (for example, a negative display polarity). Wherein, the first display polarity and the second display polarity are opposite to each other.

需注意到的是，本領域具有通常知識者可依照顯示裝置100的設計需求來決定資料線、閘極線、閘極驅動信號、顯示畫素、多工器、開關、資料端以及控制信號的數量。為方便說明，本實施例是以資料線D1～D4、閘極線G1～G3、閘極驅動信號GS1～GS3、多工器MUX2_1～MUX2_2、開關SW1～SW2以及資料端ST1～ST2來作為範例，但本發明並不限於上述所舉例的數量。It should be noted that those skilled in the art can determine the data lines, gate lines, gate drive signals, display pixels, multiplexers, switches, data terminals, and control signals according to the design requirements of the display device 100.

在本實施例中，驅動器120具有多個資料端（例如是資料端ST1、ST2），並且可透過這些資料端以分別連接至多個多工器，以使驅動器120可經由各個多工器來將畫素電壓傳送至各個對應的顯示畫素，以對各個對應的顯示畫素進行充電。另外，驅動器120可從外部接收顯示資料DA1～DAN以及擷取信號XSTB。其中，所述擷取信號XSTB用以指示驅動器120進行資料擷取的時機。此外，驅動器120可提供控制信號SC1、SC2至這些多工器，以使各個多工器的開關SW1與開關SW2可分別依據控制信號SC1與控制信號SC2來決定其導通狀態。In this embodiment, the driver 120 has a plurality of data terminals (for example, the data terminals ST1 and ST2), and the data terminals can be respectively connected to multiple multiplexers, so that the driver 120 can be connected to the multiplexers through each multiplexer. The pixel voltage is transmitted to each corresponding display pixel to charge each corresponding display pixel. In addition, the driver 120 can receive the display data DA1 ˜DAN and the captured signal XSTB from the outside. Wherein, the capture signal XSTB is used to indicate the timing of data capture by the driver 120. In addition, the driver 120 can provide control signals SC1 and SC2 to these multiplexers, so that the switch SW1 and the switch SW2 of each multiplexer can determine their conduction state according to the control signal SC1 and the control signal SC2, respectively.

特別一提的是，在顯示裝置100中，本發明可以是由源極驅動器或源極驅動器以及時脈控制器之組合來實施驅動器120的相關操作。關於相關的實施細節在後續實施例將會有相關的陳述。In particular, in the display device 100, the present invention can implement the related operations of the driver 120 by a source driver or a combination of a source driver and a clock controller. The relevant implementation details will be stated in the subsequent embodiments.

針對驅動器120的操作細節，詳細來說，首先，當顯示裝置100透過驅動器120來從外部接收多個顯示資料DA1～DAN（其中N為大於1的正整數）時，驅動器120可先依據這些顯示資料DA1～DAN的極性來產生多個第一極性資料以及多個第二極性資料。舉例來說，驅動器120可以將這些顯示資料DA1～DAN中具有正極性的顯示資料定義為第一極性資料，並且將這些顯示資料DA1～DAN中具有負極性的顯示資料定義為第二極性資料。Regarding the operation details of the driver 120, in detail, first, when the display device 100 receives a plurality of display data DA1 to DAN (where N is a positive integer greater than 1) from the outside through the driver 120, the driver 120 can first display the data The polarities of the data DA1 to DAN are used to generate a plurality of first polarity data and a plurality of second polarity data. For example, the driver 120 may define the display data with positive polarity among the display data DA1 ˜DAN as the first polarity data, and define the display data with the negative polarity among the display data DA1 ˜DAN as the second polarity data.

接著，驅動器120可依據屬於正極性的顯示資料的多個第一極性資料以及屬於負極性的顯示資料的多個第二極性資料來分別產生第一極性平均電壓以及第二極性平均電壓。舉例來說，針對第一極性資料而言，驅動器120可將各個第一極性資料中的畫素電壓進行相加，並依據相加後的總畫素電壓以及這些第一極性資料的總數目來計算出這些第一極性資料的第一極性平均電壓。相對的，針對第二極性資料而言，驅動器120亦可將各個第二極性資料中的畫素電壓進行相加，並依據相加後的總畫素電壓以及這些第二極性資料的總數目來計算出這些第二極性資料的第二極性平均電壓。Then, the driver 120 can generate the average voltage of the first polarity and the average voltage of the second polarity according to the plurality of first polarity data belonging to the positive polarity display data and the plurality of second polarity data belonging to the negative polarity display data. For example, for the first polarity data, the driver 120 may add the pixel voltages in each first polarity data, and calculate according to the total pixel voltage after the addition and the total number of these first polarity data. Calculate the average voltage of the first polarity of these first polarity data. On the other hand, for the second polarity data, the driver 120 may also add the pixel voltages in the second polarity data, and calculate according to the total pixel voltage after the addition and the total number of these second polarity data. Calculate the second polarity average voltage of these second polarity data.

具體而言，在本實施例中，當顯示裝置100操作於顯示時間區間的各個畫素充電期間時，驅動器120可依據控制信號SC1、SC2的時序狀態，來決定將各個第一極性資料中的畫素電壓對對應的第一顯示畫素（亦即顯示畫素P1_1～P3_1、P1_2～P3_2）進行充電動作，並且將各個第二極性資料中的畫素電壓對對應的第二顯示畫素（亦即顯示畫素N1_1～N3_1、N1_2～N3_2）進行充電動作。Specifically, in this embodiment, when the display device 100 is operated during the charging period of each pixel in the display time interval, the driver 120 can determine the value of the first polarity data according to the timing state of the control signals SC1 and SC2. The pixel voltage charges the corresponding first display pixels (that is, display pixels P1_1 to P3_1, P1_2 to P3_2), and the pixel voltages in each second polarity data are charged to the corresponding second display pixels ( That is, the display pixels N1_1 to N3_1, N1_2 to N3_2) are charging.

值得一提的是，在本實施例中，當顯示裝置100操作於各個畫素充電期間前的預充電期間時，驅動器120可提供第一極性平均電壓至資料端ST1，以對資料端ST1進行預充電動作，並且提供第二極性平均電壓至資料端ST2，以對資料端ST2進行預充電動作。換言之，本實施例可以在各個開關SW1、SW2導通之前（亦即所述預充電期間），先利用驅動器120對資料端ST1、ST2進行預充電的動作，以使當各個開關SW1、SW2導通（亦即所述畫素充電期間）時，第一極性資料以及第二極性資料所產生的雜訊可實質上的被相互抵消，進而提升顯示裝置100的工作效能。It is worth mentioning that, in this embodiment, when the display device 100 is operated in the pre-charging period before the charging period of each pixel, the driver 120 can provide the average voltage of the first polarity to the data terminal ST1 to perform the operation on the data terminal ST1. A pre-charging operation is performed, and the average voltage of the second polarity is provided to the data terminal ST2 to perform a pre-charging operation on the data terminal ST2. In other words, in this embodiment, before each switch SW1, SW2 is turned on (that is, during the pre-charging period), the driver 120 is used to pre-charge the data terminals ST1, ST2, so that when the switches SW1, SW2 are turned on ( That is, during the pixel charging period), the noise generated by the first-polarity data and the second-polarity data can be substantially cancelled out, thereby improving the working performance of the display device 100.

圖2A以及圖2B分別是依照本發明圖1實施例的顯示裝置在不同的開關切換順序下的動作波形圖。關於顯示裝置100的操作細節。請同時參照圖1以及圖2A，並以多工器MUX2_1以及顯示畫素P1_1～P3_1、P1_2～P3_2作為範例。其中，顯示時間區間TSA可被區分為多個預充電期間TP1～TP6以及多個畫素充電期間TC1～TC6。此外，在圖2A的實施例中，多工器MUX2_1可依據控制信號SC1、SC2使開關SW1、SW2彼此交互導通。2A and 2B are respectively operation waveform diagrams of the display device according to the embodiment of FIG. 1 of the present invention under different switching sequences. Regarding the operation details of the display device 100. Please refer to FIG. 1 and FIG. 2A at the same time, and take the multiplexer MUX2_1 and the display pixels P1_1 to P3_1, P1_2 to P3_2 as examples. Among them, the display time interval TSA can be divided into a plurality of precharge periods TP1 to TP6 and a plurality of pixel charging periods TC1 to TC6.

Furthermore, for the first polarity data, the timing controller 421 may add the pixel voltages in each first polarity data, based on the added total pixel voltage and the total number of these first polarity data To calculate the first polarity average value PA1 of these first polarity data. On the other hand, for the second polarity data, the timing controller 421 can also add the pixel voltages in the second polarity data based on the added total pixel voltage and the total number of these second polarity data. To calculate the second polarity average PA2 of these second polarity data.

換言之，在本實施例中，時序控制器421可自行將所接受到的顯示資料DA1～DAN分為多個第一極性資料以及多個第二極性資料，並且分別計算出關於這些第一極性資料的第一極性平均值PA1以及關於這些第二極性資料的第二極性平均值PA2。藉此，當驅動器420操作於各個畫素充電期間前的預充電期間時，源極驅動器422可依據所述第一極性平均值PA1以及所述第二極性平均值PA2來分別提供第一極性平均電壓以及第二極性平均電壓至資料端ST1～STN，已分別對資料端ST1～STN進行預充電的動作。In other words, in this embodiment, the timing controller 421 can automatically divide the received display data DA1 to DAN into a plurality of first polarity data and a plurality of second polarity data, and respectively calculate information about the first polarity data. The first polarity average value PA1 and the second polarity average value PA2 of the second polarity data. Therefore, when the driver 420 is operated in the pre-charging period before the charging period of each pixel, the source driver 422 can provide the first polarity average according to the first polarity average value PA1 and the second polarity average value PA2. The voltage and the average voltage of the second polarity reach the data terminals ST1 to STN, and the data terminals ST1 to STN have been precharged respectively.

Please refer to FIG. 4 and FIG. 5 at the same time. In detail, in step S510, the clock controller 421 can be activated. In step S520, the data enable signal (Data Enable Signal) in the clock controller 421 may be enabled. In step S530, the clock controller 421 may receive a plurality of display data DA1 to DAN according to the enabled data enable signal, and generate a plurality of positive polarity based on the polarity of the display data DA1 to DAN. A first polarity data and a plurality of second polarity data with negative polarity.

接著，在步驟S540中，時脈控制器421中的資料致能信號可以被禁能。在步驟S550中，時脈控制器421可分別依據這些第一極性資料以及這些第二極性資料來產生第一極性平均值以及第二極性平均值至源極驅動器422。在步驟S560中，時脈控制器421可以判斷是否被關閉，其中，當時脈控制器421未被關閉時，時脈控制器421可以執行步驟S520的操作步驟。相對的，當時脈控制器421被關閉時，時脈控制器421可以執行步驟S570的操作步驟。在步驟S570中，時脈控制器421可結束上述步驟S510～S560的操作步驟。Then, in step S540, the data enable signal in the clock controller 421 can be disabled. In step S550, the clock controller 421 can generate the first polarity average value and the second polarity average value to the source driver 422 according to the first polarity data and the second polarity data, respectively. In step S560, the clock controller 421 can determine whether it is turned off. When the clock controller 421 is not turned off, the clock controller 421 can execute the operation steps of step S520. In contrast, when the clock controller 421 is turned off, the clock controller 421 can execute the operation steps of step S570. In step S570, the clock controller 421 may end the operation steps of steps S510 to S560.
