驅動晶片130包含顯示驅動器132以及觸控驅動器134。顯示驅動器132用以輸出顯示資料訊號DS。觸控驅動器134用以輸出觸控驅動訊號TP。在一些實施例中，驅動晶片130是以觸控顯示驅動整合晶片(Touch with Display Driver integration；TDDI)實現。也就是說，顯示驅動器132以及觸控驅動器134被整合於單一個晶片中。 The driving chip 130 includes a display driver 132 and a touch driver 134. The display driver 132 is used to output a display data signal DS. The touch driver 134 is used to output a touch driving signal TP.

The second terminal of the switch S3 and the second terminal of the switch S4 are electrically connected to the common connection pad P2.
在此些實施例中，觸控驅動訊號TP是以正極性 的訊號為例，因此觸控驅動器134電性連接開關S1的第一端以及開關S3的第一端，但本揭露不以此為限。換言之，開關S1以及開關S3用以傳輸顯示資料訊號DS以及觸控驅動訊號TP。 In these embodiments, the touch driving signal TP is positive As an example, the touch driver 134 is electrically connected to the first end of the switch S1 and the first end of the switch S3, but this disclosure is not limited thereto. In other words, the switches S1 and S3 are used to transmit the display data signal DS and the touch driving signal TP.
具體而言，開關S1用以被導通以將顯示資料訊號DS以及觸控驅動訊號TP傳輸至共用連接墊P1。顯示資料訊號DS透過共用連接墊P1被傳輸至多工器120a。觸控驅動訊號TP透過共用連接墊P1被傳輸至感應線SEN1。 Specifically, the switch S1 is used to be turned on to transmit the display data signal DS and the touch driving signal TP to the common connection pad P1. The display data signal DS is transmitted to the multiplexer 120a through the common connection pad P1. The touch driving signal TP is transmitted to the sensing line SEN1 through the common connection pad P1.

The display data signal DS is transmitted to the multiplexer 120b through the common connection pad P2. The touch driving signal TP is transmitted to the sensing line SEN2 through the common connection pad P2.
在傳統作法中，顯示資料訊號DS以及觸控驅動訊號TP分別透過不同的連接墊被輸出。相較於傳統作法，在觸控顯示裝置100中，顯示資料訊號DS以及觸控驅動訊號TP透過同一個共用連接墊P1(或共用連接墊P2)被輸出，因此連接墊的數量得以減少並可降低走線的複雜度。另外，由於連接墊的數量得以減少，因此可節省用以配置連接墊的面積。 In the conventional method, the display data signal DS and the touch driving signal TP are respectively output through different connection pads. Compared with the conventional method, in the touch display device 100, the display data signal DS and the touch driving signal TP are output through the same shared connection pad P1 (or shared connection pad P2), so the number of connection pads can be reduced and Reduce the complexity of routing. In addition, since the number of connection pads is reduced, the area for arranging the connection pads can be saved.
透過感應線SEN1以及感應線SEN2被輸出的觸控驅動訊號TP將分別被輸出至觸控電極層140的不同位置。舉例而言，透過感應線SEN1被輸出的觸控驅動訊號TP是用以驅動觸控電極層140的第一觸控區。而透過感應線SEN2被輸出的觸控驅動訊號TP是用以驅動觸控電極層 140的第二觸控區。第一觸控區於觸控電極層140上的位置不同於第二觸控區於觸控電極層140上的位置。 The touch driving signals TP output through the sensing lines SEN1 and SEN2 will be respectively output to different positions of the touch electrode layer 140. For example, the touch driving signal TP output through the sensing line SEN1 is used to drive the first touch area of the touch electrode layer 140. The touch driving signal TP output through the sensing line SEN2 is used to drive the touch electrode layer. The second touch area of 140. The position of the first touch area on the touch electrode layer 140 is different from the position of the second touch area on the touch electrode layer 140.
於此需補充說明的是，第1圖中該些元件於空間上的相對關係不限於如第1圖所繪示。另外，本揭露內容不限制開關M1~M6以及開關S1~S4的型式。各種得以實現上述該些開關的電晶體皆在本揭露內容的考量範圍內。舉例而言，該些電晶體例如為雙載子接面電晶體(BJT)、金屬氧化物半導體場效電晶體(MOSFET)或絕緣閘雙極電晶體(IGBT)。 It should be added here that the relative spatial relationship of the components in Figure 1 is not limited to that shown in Figure 1. In addition, the disclosure does not limit the types of the switches M1 to M6 and the switches S1 to S4. Various transistors capable of realizing these switches are within the scope of consideration in the present disclosure. For example, the transistors are, for example, a bipolar junction transistor (BJT), a metal oxide semiconductor field effect transistor (MOSFET), or an insulated gate bipolar transistor (IGBT).
以下將對觸控顯示裝置100的運作進行詳細說明。在觸控顯示裝置100的顯示期間，顯示驅動器132的緩衝器BUF1輸出正極性的顯示資料訊號DS。開關S1以及開關S3被導通，而開關S2以及開關S4被關斷。當開關S1被導通時，開關M1~M3會依序被導通。藉此，顯示資料訊號DS將透過開關S1、共用連接墊P1以及開關M1~M3被傳輸至資料線DL1~DL3。當開關S3被導通時，開關M4~M6會依序被導通。藉此，顯示資料訊號DS將透過開關S3、共用連接墊P2以及開關M4~M6被傳輸至資料線DL4~DL6。 The operation of the touch display device 100 will be described in detail below. During the display of the touch display device 100, the buffer BUF1 of the display driver 132 outputs a display data signal DS with a positive polarity. The switches S1 and S3 are turned on, and the switches S2 and S4 are turned off. When the switch S1 is turned on, the switches M1 to M3 are sequentially turned on. Thereby, the display data signal DS will be transmitted to the data lines DL1 to DL3 through the switch S1, the common connection pad P1, and the switches M1 to M3. When the switch S3 is turned on, the switches M4 to M6 are sequentially turned on. Thereby, the display data signal DS will be transmitted to the data lines DL4 to DL6 through the switch S3, the common connection pad P2, and the switches M4 to M6.
當極性反轉發生時，顯示驅動器132的緩衝器BUF2輸出負極性的顯示資料訊號DS。開關S2以及開關S4被導通，而開關S1以及開關S3被關斷。當開關S2被導通時，開關M1~M3會依序被導通。藉此，顯示資料訊號DS將透過開關S2、共用連接墊P1以及開關M1~M3被傳輸至資料線DL1~DL3。當開關S4被導通時，開關M4~M6會依 序被導通。藉此，顯示資料訊號DS將透過開關S4、共用連接墊P2以及開關M4~M6被傳輸至資料線DL4~DL6。 When the polarity inversion occurs, the buffer BUF2 of the display driver 132 outputs a negative display data signal DS. The switches S2 and S4 are turned on, and the switches S1 and S3 are turned off. When the switch S2 is turned on, the switches M1 to M3 are sequentially turned on. Thereby, the display data signal DS will be transmitted to the data lines DL1 to DL3 through the switch S2, the common connection pad P1, and the switches M1 to M3.

在觸控顯示裝置100的觸控期間，觸控驅動器134輸出觸控驅動訊號TP。此時，開關S1以及開關S3將會被導通。開關S1被導通以將觸控驅動訊號TP傳輸至共用連接墊P1，使得觸控驅動訊號TP透過感應線SEN1被傳輸至觸控電極層140的第一觸控區。接著，開關S3被導通以將觸控驅動訊號TP傳輸至共用連接墊P2，使得觸控驅動訊號TP透過感應線SEN2被傳輸至觸控電極層140的第二觸控區。在觸控顯示裝置100的觸控期間，開關M1~M6皆被關斷。藉此，觸控驅動訊號TP不會透過多工器120a或120b被傳輸至顯示陣列110。 During the touch of the touch display device 100, the touch driver 134 outputs a touch driving signal TP. At this time, the switches S1 and S3 will be turned on. The switch S1 is turned on to transmit the touch driving signal TP to the common connection pad P1, so that the touch driving signal TP is transmitted to the first touch area of the touch electrode layer 140 through the sensing line SEN1. Then, the switch S3 is turned on to transmit the touch driving signal TP to the common connection pad P2, so that the touch driving signal TP is transmitted to the second touch area of the touch electrode layer 140 through the sensing line SEN2. During the touch period of the touch display device 100, the switches M1 to M6 are all turned off. Therefore, the touch driving signal TP is not transmitted to the display array 110 through the multiplexer 120a or 120b.

FIG. 3 is a schematic diagram of a touch display device 300 according to some embodiments of the disclosure. For ease of understanding, similar elements in Figure 3 will be assigned the same reference numerals as in Figure 1.
第3圖的觸控顯示裝置300與第1圖的觸控顯示裝置100之間的不同在於，觸控顯示裝置300更包含開關S5以及開關S6。開關S5與感應線SEN1電性連接於節點N1與觸控電極層140之間。開關S6與感應線SEN2電性連接於節點N2與觸控電極層140之間。具體而言，感應線SEN1包含第一線段以及第二線段。感應線SEN1的第一線段電性連接於節點N1與開關S5的第一端之間。感應線SEN1的第二線段電性連接於開關S5的第二端與觸控電極層140之間。感應線SEN2包含第一線段以及第二線段。感應線SEN2的第一線段電性連接於節點N2與開關S6的第一端之間。感應線SEN2的第二線段電性連接於開關S6的第二端與觸控電極層140之間。 The difference between the touch display device 300 in FIG. 3 and the touch display device 100 in FIG. 1 is that the touch display device 300 further includes a switch S5 and a switch S6. The switch S5 and the sensing line SEN1 are electrically connected between the node N1 and the touch electrode layer 140. The switch S6 and the sensing line SEN2 are electrically connected between the node N2 and the touch electrode layer 140. Specifically, the sensing line SEN1 includes a first line segment and a second line segment. The first line segment of the sensing line SEN1 is electrically connected between the node N1 and the first end of the switch S5. The second line segment of the sensing line SEN1 is electrically connected between the second end of the switch S5 and the touch electrode layer 140. The sensing line SEN2 includes a first line segment and a second line segment. The first line segment of the sensing line SEN2 is electrically connected between the node N2 and the first end of the switch S6. The second line segment of the sensing line SEN2 is electrically connected between the second end of the switch S6 and the touch electrode layer 140.
在觸控顯示裝置100的顯示期間，開關S5以及開關S6被關斷。藉此，顯示資料訊號DS不會透過感應線SEN1以及感應線SEN2被傳輸至觸控電極層140。而在觸控顯示裝置100的觸控期間，開關S5以及開關S6被導通。藉此，觸控驅動訊號TP將透過感應線SEN1、感應線SEN2、開關S5以及開關S6被傳輸至觸控電極層140。 During the display of the touch display device 100, the switches S5 and S6 are turned off. Therefore, the display data signal DS is not transmitted to the touch electrode layer 140 through the sensing lines SEN1 and SEN2. During the touch of the touch display device 100, the switches S5 and S6 are turned on. Accordingly, the touch driving signal TP is transmitted to the touch electrode layer 140 through the sensing line SEN1, the sensing line SEN2, the switch S5, and the switch S6.
請參考第4圖。第4圖是依照本揭露一些實施例所繪示的一種觸控顯示裝置300的部分結構示意圖。換句話說，第4圖繪示出第3圖的觸控顯示裝置300的部分結構。 Please refer to Figure 4. FIG. 4 is a partial structural diagram of a touch display device 300 according to some embodiments of the disclosure. In other words, FIG. 4 illustrates a partial structure of the touch display device 300 of FIG. 3.
示例而言，第4圖中的結構由上而下依序為偏光層402、觸控電極層140、濾光層404、液晶層406、驅動電晶體玻璃層408以及偏光層410。在此示意圖中各層別的順 序僅為示意，本揭露不以此為限。舉例而言，觸控電極層140亦可位於濾光層404和液晶層406之間。在這些實施例中，觸控電極層140的觸控電極與共用電壓層(Vcom)的電極為共用。由於觸控電極層140的觸控電極與共用電壓層(Vcom)的電極為共用，因此觸控顯示裝置400需配置開關S5以及開關S6，讓觸控電極層140能夠在對應的時段分別接收觸控訊號與共同電壓訊號。換句話說，通過配置開關S5和開關S6能夠使得觸控電極層140將觸控訊號和共同電壓訊號區隔開來。 For example, the structure in FIG. 4 is a polarizing layer 402, a touch electrode layer 140, a filter layer 404, a liquid crystal layer 406, a driving transistor glass layer 408, and a polarizing layer 410 in order from top to bottom. The order of the layers in this diagram The preface is only for illustration, and this disclosure is not limited to this. For example, the touch electrode layer 140 may also be located between the filter layer 404 and the liquid crystal layer 406. In these embodiments, the touch electrodes of the touch electrode layer 140 are shared with the electrodes of the common voltage layer (Vcom). Since the touch electrodes of the touch electrode layer 140 and the electrodes of the common voltage layer (Vcom) are shared, the touch display device 400 needs to be equipped with a switch S5 and a switch S6, so that the touch electrode layer 140 can receive touches at corresponding times.

請參考第5圖。第5圖是依照本揭露一些實施例所繪示的一種觸控顯示裝置500的示意圖。為易於理解之目的，於第5圖中的類似元件將與第1圖指定相同標號。 Please refer to Figure 5. FIG. 5 is a schematic diagram of a touch display device 500 according to some embodiments of the disclosure. For ease of understanding, similar elements in Figure 5 will be assigned the same reference numerals as in Figure 1.

Specifically, the sensing lines SEN1 to SEN6 and the data lines DL1 to DL6 are electrically connected in a one-to-one manner. The sensing lines SEN1 to SEN6 are further electrically connected to the touch electrode layer 140.
接著，請一併參考第5圖以及第6圖。第6圖是第5圖的觸控顯示裝置500的多個訊號的時序圖。第6圖的時序包含顯示期間DIS_TIME、觸控期間TP_TIME1以及觸控期間TP_TIME2。 Next, please refer to Figure 5 and Figure 6 together. FIG. 6 is a timing diagram of a plurality of signals of the touch display device 500 of FIG. 5. The timing of FIG. 6 includes a display period DIS_TIME, a touch period TP_TIME1, and a touch period TP_TIME2.
第6圖中繪示了顯示資料訊號DS以及觸控驅動訊號TP(第6圖的下方)。在顯示期間DIS_TIME，顯示驅動器132輸出顯示資料訊號DS以實現顯示功能。在觸控期間TP_TIME1以及觸控期間TP_TIME2，觸控驅動器134輸出 觸控驅動訊號TP以實現觸控功能。 Figure 6 shows the display data signal DS and the touch drive signal TP (bottom of Figure 6). During the display period DIS_TIME, the display driver 132 outputs a display data signal DS to implement a display function. During the touch period TP_TIME1 and touch period TP_TIME2, the touch driver 134 outputs The touch driving signal TP realizes the touch function.
第6圖中更繪示了掃描訊號VG1~VG3、控制訊號MS1~MS6、控制訊號SS1~SS4的電壓訊號波形。上述該些電壓訊號具有邏輯位準VGH(例如：高邏輯位準)以及邏輯位準VGL(例如：低邏輯位準)。在此些實施例中，子畫素中的驅動電晶體以及各開關是以N型電晶體實現。因此各電壓訊號的致能期間對應於邏輯位準VGH。反之，在一些其他的實施例中，若子畫素中的驅動電晶體以及各開關是以P型電晶體實現，各電壓訊號的致能期間將改為對應於邏輯位準VGL。 FIG. 6 further shows the voltage signal waveforms of the scanning signals VG1 to VG3, the control signals MS1 to MS6, and the control signals SS1 to SS4. The above voltage signals have a logic level VGH (for example: a high logic level) and a logic level VGL (for example: a low logic level). In these embodiments, the driving transistor and each switch in the sub-pixel are implemented by an N-type transistor. Therefore, the enabling period of each voltage signal corresponds to the logic level VGH. Conversely, in some other embodiments, if the driving transistor and each switch in the sub-pixel are implemented by a P-type transistor, the enabling period of each voltage signal will be changed to correspond to the logic level VGL.
為了易於瞭解之目的，第6圖繪示了複數個掃描訊號VG1~VG3，但本揭露不以此數量為限。這些掃描訊號VG1~VG3包含於第5圖的掃描訊號VG當中。這些掃描訊號VG1~VG3分別用以控制各列子畫素中驅動電晶體的導通狀態。 For the purpose of easy understanding, FIG. 6 illustrates a plurality of scanning signals VG1 to VG3, but this disclosure is not limited to this number. These scan signals VG1 to VG3 are included in the scan signals VG in FIG. 5. These scanning signals VG1 to VG3 are respectively used to control the conduction states of the driving transistors in each column of sub-pixels.
具體而言，掃描訊號VG1被傳輸至電性連接至第一列子畫素的第一掃描線SL1。掃描訊號VG2被傳輸至電性連接至第二列子畫素的第二掃描線(圖未示)。掃描訊號VG3被傳輸至電性連接至第三列子畫素的第三掃描線(圖未示)。以第6圖示例而言，掃描訊號VG1的致能期間在時序上早於掃描訊號VG2的致能期間。掃描訊號VG2的致能期間在時序上早於掃描訊號VG3的致能期間。也就是說，該些列子畫素的驅動電晶體的驅動順序為第一列子畫素的驅動電晶體、第二列子畫素的驅動電晶體以及第三列子畫素的驅動 電晶體。 Specifically, the scan signal VG1 is transmitted to the first scan line SL1 electrically connected to the first row of sub-pixels. The scanning signal VG2 is transmitted to a second scanning line (not shown) electrically connected to the second row of sub-pixels. The scanning signal VG3 is transmitted to a third scanning line (not shown) electrically connected to the third row of sub-pixels. Taking the example in FIG. 6, the enabling period of the scanning signal VG1 is earlier in timing than the enabling period of the scanning signal VG2. The enabling period of the scanning signal VG2 is earlier in timing than the enabling period of the scanning signal VG3. In other words, the driving sequence of the driving transistors of the sub-pixels is the driving transistor of the first sub-pixel, the driving transistors of the second sub-pixel, and the driving of the third sub-pixel. Transistor.
需特別說明的是，各種掃描的方式皆在本揭露的範圍內，例如：正向掃描(forward scan)、反向掃描(reverse scan)或其他各種掃描方式。 It should be particularly noted that various scanning methods are within the scope of this disclosure, such as: forward scan, reverse scan, or other various scanning methods.
第6圖中的控制訊號MS1~MS6分別被傳輸至開關M1~M6的控制端(例如：閘極端)，以控制開關M1~M6的導通狀態。在一些實施例中，控制訊號MS1相同於控制訊號MS4。控制訊號MS2相同於控制訊號MS5。控制訊號MS3相同於控制訊號MS6。也就是說，當開關M1被導通時，開關M4亦被導通。當開關M2被導通時，開關M5亦被導通。當開關M3被導通時，開關M6亦被導通。 The control signals MS1 ~ MS6 in Fig. 6 are transmitted to the control terminals (eg, gate terminals) of the switches M1 ~ M6, respectively, to control the conducting states of the switches M1 ~ M6. In some embodiments, the control signal MS1 is the same as the control signal MS4. The control signal MS2 is the same as the control signal MS5. The control signal MS3 is the same as the control signal MS6. That is, when the switch M1 is turned on, the switch M4 is also turned on. When the switch M2 is turned on, the switch M5 is also turned on. When the switch M3 is turned on, the switch M6 is also turned on.
第6圖中的控制訊號SS1~SS4分別被傳輸至開關S1~S4的控制端(例如：閘極端)，以控制開關S1~S4的導通狀態。具體而言，在掃描訊號VG1的致能期間，開關S1會依據控制訊號SS1而被導通。藉此，顯示資料訊號DS會透過開關S1被傳輸至共用連接墊P1。同時，開關M1~M3會依據控制訊號MS1~MS3依序被導通。藉此，顯示資料訊號DS會透過開關M1~M3被傳輸至資料線DL1~DL3。此時，子畫素R1、G1、B1中的液晶電容分別依據來自資料線DL1~DL3的顯示資料訊號DS被充電至對應的電壓位準，以達到顯示的功能。 The control signals SS1 to SS4 in FIG. 6 are transmitted to the control terminals (eg, gate terminals) of the switches S1 to S4, respectively, to control the conduction states of the switches S1 to S4. Specifically, during the enabling period of the scanning signal VG1, the switch S1 is turned on according to the control signal SS1. Thereby, the display data signal DS is transmitted to the common connection pad P1 through the switch S1. At the same time, the switches M1 ~ M3 are sequentially turned on according to the control signals MS1 ~ MS3. As a result, the display data signal DS is transmitted to the data lines DL1 to DL3 through the switches M1 to M3. At this time, the liquid crystal capacitors in the sub-pixels R1, G1, and B1 are respectively charged to the corresponding voltage levels according to the display data signals DS from the data lines DL1 to DL3 to achieve the display function.
另外，在掃描訊號VG1的致能期間，開關S3亦會依據控制訊號SS3而被導通。藉此，顯示資料訊號DS會透過開關S3被傳輸至共用連接墊P2。同時，開關M4~M6 會依據控制訊號MS4~MS6依序被導通。藉此，顯示資料訊號DS會透過開關M4~M6將被傳輸至資料線DL4~DL6。此時，子畫素R2、G2、B2中的液晶電容分別依據來自資料線DL4~DL6的顯示資料訊號DS被充電至對應的電壓位準，以達到顯示的功能。 In addition, during the enabling period of the scanning signal VG1, the switch S3 is also turned on according to the control signal SS3. Thereby, the display data signal DS is transmitted to the common connection pad P2 through the switch S3. At the same time, switches M4 ~ M6 Will be turned on sequentially according to the control signals MS4 ~ MS6. With this, the display data signal DS will be transmitted to the data lines DL4 to DL6 through the switches M4 to M6. At this time, the liquid crystal capacitors in the sub-pixels R2, G2, and B2 are respectively charged to the corresponding voltage levels according to the display data signals DS from the data lines DL4 to DL6 to achieve the display function.
由於掃描訊號VG2以及掃描訊號VG3具有對應於掃描訊號VG1的內容，故於此不再贅述。 Since the scan signal VG2 and the scan signal VG3 have contents corresponding to the scan signal VG1, they are not described again here.
在觸控期間TP_TIME1，開關S1依據控制訊號SS1被導通。藉此，觸控訊號TP會透過開關S1被傳輸至共用連接墊P1。同時，開關M1~M3依據控制訊號MS1~MS3依序被導通。藉此，觸控訊號TP會透過開關M1~M3被傳輸至資料線DL1~DL3，進而透過感應線SEN1~SEN3被傳輸至觸控電極層140。 During the touch period TP_TIME1, the switch S1 is turned on according to the control signal SS1. As a result, the touch signal TP is transmitted to the common connection pad P1 through the switch S1. At the same time, the switches M1 ~ M3 are sequentially turned on according to the control signals MS1 ~ MS3. Accordingly, the touch signal TP is transmitted to the data lines DL1 to DL3 through the switches M1 to M3, and then transmitted to the touch electrode layer 140 through the sensing lines SEN1 to SEN3.
相似的，在觸控期間TP_TIME2，開關S3將依據控制訊號SS3被導通。藉此，觸控訊號TP會透過開關S3被傳輸至共用連接墊P2。在此同時，開關M4~M6依據控制訊號MS4~MS6依序被導通。藉此，觸控訊號TP會透過開關M4~M6被傳輸至資料線DL4~DL6，進而透過感應線SEN4~SEN6被傳輸至觸控電極層140。 Similarly, during the touch period TP_TIME2, the switch S3 will be turned on according to the control signal SS3. As a result, the touch signal TP is transmitted to the common connection pad P2 through the switch S3. At the same time, the switches M4 ~ M6 are sequentially turned on according to the control signals MS4 ~ MS6. Accordingly, the touch signal TP is transmitted to the data lines DL4 to DL6 through the switches M4 to M6, and then transmitted to the touch electrode layer 140 through the sensing lines SEN4 to SEN6.
需特別注意的是，在觸控期間TP_TIME1以及觸控期間TP_TIME2，所有的掃描訊號皆對應於非致能期間(禁能期間)。換言之，所有的掃描訊號的電壓位準皆為低邏輯位準(邏輯位準VGL)。在這種情況下，所有子畫素的驅動電晶體皆為被關斷，因此觸控訊號TP不會被傳輸至所有子 畫素中的液晶電容。 It should be noted that during the touch period TP_TIME1 and the touch period TP_TIME2, all the scanning signals correspond to the non-enabled period (disabled period). In other words, the voltage level of all the scanning signals is a low logic level (logic level VGL). In this case, the driving transistors of all sub-pixels are turned off, so the touch signal TP will not be transmitted to all sub-pixels. Liquid crystal capacitors in pixels.
需補充說明的是，由於在此些實施例中，顯示資料訊號DS以及觸控驅動訊號TP是以正極性訊號為例。因此，開關S2依據控制訊號SS2被關斷，開關S4依據控制訊號SS4被關斷。 It should be added that, because in these embodiments, the display data signal DS and the touch driving signal TP are positive polarity signals as examples. Therefore, the switch S2 is turned off according to the control signal SS2, and the switch S4 is turned off according to the control signal SS4.
綜上所述，在本揭露內容的觸控顯示裝置中，顯示驅動器與觸控驅動器透過一共用連接墊分別輸出顯示資料訊號以及觸控驅動訊號，使得連接墊的數量得以減少並降低走線的複雜度。另外可節省用以配置連接墊的面積。 In summary, in the touch display device of the present disclosure, the display driver and the touch driver respectively output the display data signal and the touch driving signal through a shared connection pad, so that the number of connection pads can be reduced and the routing the complexity. In addition, the area for configuring the connection pad can be saved.
