FIG. 4 is a further detailed flowchart of the touch driving method 300 in FIG. 3 according to some embodiments of the present disclosure, wherein step S320 in FIG. 3 includes step S410 and step S330 further includes steps S420 to S460. FIG. 5 is a timing diagram of the touch driving method 300 in FIG. 4 according to an embodiment of the present disclosure.

於步驟S410中，觸控驅動單元120偵測觸控驅動單元120的觸控輸入感測端RX是否存在干擾訊號Sn。於此步驟中，干擾訊號Sn可以是經由偵測觸控輸入感測端 RX的訊號的變化而分析得知的，觸控驅動單元120進一步將此干擾訊號Sn傳送至觸控控制單元110。 In step S410, the touch driving unit 120 detects whether the touch input sensing terminal RX of the touch driving unit 120 has an interference signal Sn. In this step, the interference signal Sn may be detected by detecting a touch input. According to the analysis of the change of the RX signal, the touch driving unit 120 further transmits the interference signal Sn to the touch control unit 110.

於一些實施例中，若觸控控制單元110判斷觸控驅動單元120的觸控輸入感測端RX存在干擾訊號Sn，執行步驟S420。若觸控控制單元110判斷觸控驅動單元120的觸控輸入感測端RX不存在干擾訊號Sn，執行步驟S470，觸控控制單元110依據同步訊號Ssync產生觸發脈衝Ptri，並且觸控驅動單元120依據觸發脈衝Ptri產生觸控驅動脈衝Ptou。 In some embodiments, if the touch control unit 110 determines that the touch input sensing terminal RX of the touch driving unit 120 has an interference signal Sn, step S420 is performed. If the touch control unit 110 determines that there is no interference signal Sn at the touch input sensing terminal RX of the touch drive unit 120, step S470 is executed, the touch control unit 110 generates a trigger pulse Ptri according to the synchronization signal Ssync, and the touch drive unit 120 The touch driving pulse Ptou is generated according to the trigger pulse Ptri.

於步驟S420中，設定延遲時間，於一些實施例中，步驟S420設定的延遲時間是一個初始的延遲時間d1(如第5圖所示)，舉例來說，在步驟S420當中可以將初始的延遲時間d1設定為為1ms。 In step S420, a delay time is set. In some embodiments, the delay time set in step S420 is an initial delay time d1 (as shown in FIG. 5). For example, the initial delay time can be set in step S420. The time d1 is set to 1 ms.

於步驟S430中，觸控控制單元110依據同步脈衝Ssync和初始的延遲時間d1產生一個觸發脈衝P311。以第5圖為例示，觸發脈衝P311的起始時間點為同步脈衝P11加上延遲時間d1。並且步驟S430產生與觸發脈衝P311相應的觸控驅動脈衝P411。於此實施例中，觸控驅動脈衝P411的起始點由觸發脈衝P311的時間點決定，而觸控驅動脈衝P411的持續時間由觸控驅動單元120完成一次觸控偵測所需要的時間長度而決定。若觸控驅動單元120完成一次觸控偵測所需要的時間愈短，則觸控驅動脈衝P411的持續時間則愈短。 In step S430, the touch control unit 110 generates a trigger pulse P311 according to the synchronization pulse Ssync and the initial delay time d1. Taking FIG. 5 as an example, the starting point of the trigger pulse P311 is the synchronization pulse P11 plus the delay time d1. And step S430 generates a touch driving pulse P411 corresponding to the trigger pulse P311. In this embodiment, the starting point of the touch drive pulse P411 is determined by the time point of the trigger pulse P311, and the duration of the touch drive pulse P411 is the time required for the touch drive unit 120 to complete a touch detection. And decide. If the time required for the touch driving unit 120 to complete one touch detection is shorter, the duration of the touch driving pulse P411 is shorter.

於步驟S440中，觸控控制單元110偵測觸控 驅動脈衝P411的持續期間，是否受到干擾訊號Sn影響。若觸控控制單元110判斷在觸控驅動脈衝P411期間受到干擾訊號Sn的影響，以第5圖為例示，觸控控制單元110判斷在觸控驅動脈衝P411期間受到干擾訊號Sn的干擾脈衝P211的影響，則執行步驟S450，計算新的延遲時間d，並據以產生另一觸發脈衝Ptri及相應的觸控驅動脈衝Ptou。於一實施例中，新的延遲時間d的計算是將延遲時間遞增，也就是說，新的延遲時間d2可以是先前的延遲時間d1加上一定的時間差。舉例來說，可以將目前的延遲時間d1(1ms)加上一定的時間差(1ms)等於新的延遲時間d2(2ms)，需特別說明的是，上述延遲時間d1、延遲時間d2及時間差的數值只是為了舉例說明上的方便，本揭示文件並不僅限於上述時間數值，延遲時間的數值可視實際應用的需求而調整。 In step S440, the touch control unit 110 detects a touch Whether the duration of the driving pulse P411 is affected by the interference signal Sn. If the touch control unit 110 determines that it is affected by the interference signal Sn during the touch drive pulse P411, taking FIG. 5 as an example, the touch control unit 110 determines that the interference pulse P211 is affected by the interference signal Sn during the touch drive pulse P411. If it is affected, step S450 is executed to calculate a new delay time d and generate another trigger pulse Ptri and corresponding touch driving pulse Ptou accordingly. In an embodiment, the calculation of the new delay time d is to increase the delay time, that is, the new delay time d2 may be the previous delay time d1 plus a certain time difference. For example, the current delay time d1 (1ms) plus a certain time difference (1ms) can be equal to the new delay time d2 (2ms). It should be noted that the above-mentioned delay time d1, delay time d2 and the value of the time difference Just for convenience of illustration, the present disclosure is not limited to the above time value, and the value of the delay time can be adjusted according to the requirements of actual applications.

計算出新的延遲時間d2後，步驟S450將依據新的延遲時間d2在下個同步脈衝P12抵達時產生新的觸控驅動脈衝P321，觸控驅動脈衝P321的起始時間點為同步脈衝P12加上延遲時間d2，並且步驟S450將產生與觸控驅動脈衝P321相應的觸控驅動脈衝P421，如第4圖及第5圖所示，於此實施例中，觸控驅動脈衝P421的起始點由觸發脈衝P321的時間點決定，而觸控驅動脈衝P421的持續時間由觸控驅動單元120完成一次觸控偵測所需要的時間長度而決定。此時再次執行步驟S440，判斷觸控驅動脈衝P421的其間是否受到干擾訊號Sn的干擾。 After calculating the new delay time d2, step S450 will generate a new touch driving pulse P321 when the next synchronization pulse P12 arrives according to the new delay time d2. The starting point of the touch driving pulse P321 is the synchronization pulse P12 plus The delay time d2, and step S450 will generate a touch driving pulse P421 corresponding to the touch driving pulse P321, as shown in FIG. 4 and FIG. 5. In this embodiment, the starting point of the touch driving pulse P421 is The time point of the trigger pulse P321 is determined, and the duration of the touch driving pulse P421 is determined by the time required for the touch driving unit 120 to complete one touch detection. At this time, step S440 is executed again to determine whether the touch driving pulse P421 is interfered by the interference signal Sn in the meantime.

以第5圖為例示，觸控控制單元110判斷在觸控驅動脈衝P421期間仍然受到干擾訊號Sn的干擾脈衝P221的影響，則再次執行步驟S450，再次計算新的延遲時間d，並據以產生另一觸發脈衝Ptri及相應的觸控驅動脈衝Ptou。此時，步驟S450計算出的新的延遲時間d3可以是先前的延遲時間d2加上一定的時間差，舉例來說，可以將目前的延遲時間d2(2ms)加上一定的時間差(1ms)等於新的延遲時間d3(3ms)。計算出新的延遲時間d3後，步驟S450將依據新的延遲時間d3在下個同步脈衝P13抵達時產生新的觸控驅動脈衝P331，觸控驅動脈衝P331的起始時間點為同步脈衝P13加上延遲時間d3，並且步驟S450將產生與觸控驅動脈衝P331相應的觸控驅動脈衝P431。 Taking FIG. 5 as an example, the touch control unit 110 determines that it is still affected by the interference pulse P221 of the interference signal Sn during the touch driving pulse P421, and then executes step S450 again, calculates a new delay time d again, and generates accordingly Another trigger pulse Ptri and corresponding touch driving pulse Ptou. At this time, the new delay time d3 calculated in step S450 may be the previous delay time d2 plus a certain time difference. For example, the current delay time d2 (2ms) plus a certain time difference (1ms) is equal to the new Delay time d3 (3ms). After the new delay time d3 is calculated, step S450 will generate a new touch drive pulse P331 when the next synchronization pulse P13 arrives according to the new delay time d3. The starting point of the touch drive pulse P331 is the synchronization pulse P13 plus The delay time d3, and step S450 will generate a touch driving pulse P431 corresponding to the touch driving pulse P331.

如第4圖及第5圖所示。此時再次執行步驟S440，判斷觸控驅動脈衝P431的其間是否受到干擾訊號Sn的干擾。此時，觸控控制單元110判斷在觸控驅動脈衝P431期間未受到干擾訊號Sn的影響，以第5圖為例示，觸控控制單元110判斷在觸控驅動脈衝P431期間未受到干擾訊號Sn的干擾脈衝P231,P232或其他干擾脈衝的影響，則執行步驟S460。 As shown in Figure 4 and Figure 5. At this time, step S440 is executed again to determine whether the touch driving pulse P431 is interfered by the interference signal Sn in the meantime. At this time, the touch control unit 110 determines that it is not affected by the interference signal Sn during the touch drive pulse P431. Taking FIG. 5 as an example, the touch control unit 110 determines that the interference signal Sn is not affected during the touch drive pulse P431. If the influence of the interference pulses P231, P232 or other interference pulses, step S460 is performed.

於一些實施例中，於步驟S460中，觸控控制單元110依據觸發脈衝Ptri的時間點以及同步訊號Ssync的固定週期TP1的等分區間長度產生接續的觸發脈衝Ptri。以第5圖為例示，觸控控制單元110將固定週期TP1分為 三個等分區間長度，因此產生三個觸發脈衝P331、P332及P333。觸發脈衝P331、P332及P333彼此之間間隔固定週期TP1的三分之一。 In some embodiments, in step S460, the touch control unit 110 generates consecutive trigger pulses Ptri according to the time point of the trigger pulse Ptri and the equal inter-zone length of the fixed period TP1 of the synchronization signal Ssync. Taking FIG. 5 as an example, the touch control unit 110 divides the fixed period TP1 into The length between three equal divisions, so three trigger pulses P331, P332 and P333 are generated. The trigger pulses P331, P332 and P333 are spaced from each other by a third of a fixed period TP1.

所述等分區間長度可以視為同步訊號Ssync的固定週期TP1的三等分(亦即固定週期TP1的三分之一)。於另一實施例中，也可以依照資料啟動訊號Sd的固定週期來進行等分，也就是說，觸發脈衝P331、P332及P333之間彼此間隔的等分區間長度可以設定為的資料啟動訊號Sd的固定週期TP2的三分之一。 The length between equal partitions can be regarded as three equal parts of the fixed period TP1 of the synchronization signal Ssync (that is, one third of the fixed period TP1). In another embodiment, the data can be equally divided according to a fixed period of the data activation signal Sd. That is, the equal interval length between the trigger pulses P331, P332, and P333 can be set as the data activation signal Sd. One third of the fixed period TP2.

如此一來，觸控控制單元110將觸發脈衝P331、P332及P333傳送至觸控驅動單元120，觸控驅動單元120依據觸發脈衝P331、P332、P333產生觸控脈衝P431、P432和P433，使得觸控顯示裝置100接收觸控驅動訊號Stou的時段不會受到顯示特定圖案所產生的雜訊所影響。 In this way, the touch control unit 110 transmits trigger pulses P331, P332, and P333 to the touch drive unit 120, and the touch drive unit 120 generates touch pulses P431, P432, and P433 according to the trigger pulses P331, P332, and P333, so that the touch The time period for controlling the display device 100 to receive the touch driving signal Stou is not affected by the noise generated by displaying the specific pattern.

於上述實施例中，觸控控制單元110產生三組觸發脈衝P331、P332及P333作為舉例說明，然而本揭示文件並不以此為限。於另外一些實施例中，為了進一步調高觸控控制單元110的回報率(即縮短掃描間隔)，可增加觸發脈衝的次數(例如四次以上)，只要能夠避開驅動訊號Stou上的雜訊，即可在避免受到雜訊影響的情況下進一步提高觸控控制單元110的回報率。於另外一些實施例，若觸控控制單元110不需要高回報率，亦可以在一個同步訊號Ssync的固定週期TP1當中僅產生一個或兩個觸發脈衝。 In the above embodiment, the touch control unit 110 generates three sets of trigger pulses P331, P332, and P333 as examples, but this disclosure is not limited thereto. In other embodiments, in order to further increase the return rate of the touch control unit 110 (ie, shorten the scanning interval), the number of trigger pulses (for example, four or more times) can be increased, as long as the noise on the driving signal Stou can be avoided That is, the return rate of the touch control unit 110 can be further improved without being affected by noise. In other embodiments, if the touch control unit 110 does not need a high return rate, it can also generate only one or two trigger pulses in a fixed period TP1 of a synchronization signal Ssync.

第6圖係根據本揭示內容之部分實施例繪示第3圖中觸控驅動方法300的進一步細節流程圖，其中第6圖所示之驅動方法300和第4圖所示之驅動方法300之差別在於第6圖中的步驟S330包含步驟S620至S670。 FIG. 6 is a further detailed flowchart of the touch driving method 300 in FIG. 3 according to some embodiments of the present disclosure. Among them, the driving method 300 shown in FIG. 6 and the driving method 300 shown in FIG. The difference is that step S330 in FIG. 6 includes steps S620 to S670.

由於第6圖所示之步驟S310、S410、S420、S340和S470已在第3圖和第4圖中說明，於此不再贅述。 Since steps S310, S410, S420, S340, and S470 shown in FIG. 6 have been described in FIGS. 3 and 4, they are not described again here.

一併參照第6圖和第7圖，其中第7圖係根據本揭示內容之一實施例所繪示第6圖中觸控驅動方法300的說明示例。 Referring to FIG. 6 and FIG. 7 together, FIG. 7 is an illustrative example of the touch driving method 300 in FIG. 6 according to an embodiment of the present disclosure.

於步驟S620中，設定延遲時間，於一些實施例中，步驟S620設定的延遲時間是一個初始的延遲時間d1(如第7圖所示)，舉例來說，在步驟S620當中可以將初始的延遲時間d1設定為為1ms。 In step S620, a delay time is set. In some embodiments, the delay time set in step S620 is an initial delay time d1 (as shown in FIG. 7). For example, the initial delay time can be set in step S620. The time d1 is set to 1 ms.

於步驟S630中，觸控控制單元110依據同步脈衝P11和初始的延遲時間d1產生一個觸發脈衝P311。以第5圖為例示，觸發脈衝P311的起始時間點為同步脈衝P11加上延遲時間d1。 In step S630, the touch control unit 110 generates a trigger pulse P311 according to the synchronization pulse P11 and the initial delay time d1. Taking FIG. 5 as an example, the starting point of the trigger pulse P311 is the synchronization pulse P11 plus the delay time d1.

步驟S640中，觸控控制單元110估算由觸發脈衝P311的起始點至後續的干擾脈衝Pn任一者(於第7圖的實施例中為干擾脈衝P211)之間的無雜訊區間(或是低雜訊區間)長度L11。 In step S640, the touch control unit 110 estimates a noise-free interval (or from the starting point of the trigger pulse P311 to any of the subsequent interference pulses Pn (the interference pulse P211 in the embodiment in FIG. 7)). Is the low noise interval) length L11.

接著，執行步驟S650，觸控控制單元110判斷觸發脈衝P311的無雜訊區間(或是低雜訊區間)長度L11是否大於觸控驅動脈衝P411之脈衝長度L2。 Next, step S650 is executed, and the touch control unit 110 determines whether the length L11 of the noise-free interval (or low-noise interval) of the trigger pulse P311 is greater than the pulse length L2 of the touch driving pulse P411.

此時，由於觸發脈衝P311的無雜訊區間(或是低雜訊區間)長度L11並未大於觸控驅動脈衝P411之脈衝長度L2。 At this time, the length L11 of the noise-free interval (or low-noise interval) of the trigger pulse P311 is not greater than the pulse length L2 of the touch driving pulse P411.

因此，執行步驟S660，觸控控制單元110計算新的延遲時間d2，並根據新的延遲時間d2產生對應的另一觸發脈衝P321，此步驟的細節可以參照第4圖之實施立中的步驟S450。 Therefore, in step S660, the touch control unit 110 calculates a new delay time d2 and generates another corresponding trigger pulse P321 according to the new delay time d2. For details of this step, refer to step S450 in the implementation of FIG. 4 .

接續執行步驟S640，觸控控制單元110估算由觸發脈衝P321的起始點至後續的干擾脈衝Pn任一者(於第7圖的實施例中為干擾脈衝P221)之間的無雜訊區間(或是低雜訊區間)長度L12。步驟S650中，觸控控制單元110判斷觸發脈衝P321的無雜訊區間(或是低雜訊區間)長度L12仍然小於觸控驅動脈衝P421之脈衝長度L2，因而再次執行步驟S660，觸控控制單元110計算不同於延遲時間d2的延遲時間d3，並根據延遲時間d3產生對應於同步脈衝P13的另一觸發脈衝P331，並接續執行步驟S640。 Following step S640, the touch control unit 110 estimates a noise-free interval (from the starting point of the trigger pulse P321 to any of the subsequent interference pulses Pn (the interference pulse P221 in the embodiment in FIG. 7)). Or low noise interval) length L12. In step S650, the touch control unit 110 determines that the length L12 of the noise-free interval (or low-noise interval) of the trigger pulse P321 is still shorter than the pulse length L2 of the touch drive pulse P421, so the step S660 is performed again, and the touch control unit 110 calculates a delay time d3 different from the delay time d2, and generates another trigger pulse P331 corresponding to the synchronization pulse P13 according to the delay time d3, and then proceeds to step S640.

步驟S640，觸控控制單元110估算由觸發脈衝P331的起始點至後續的干擾脈衝Pn任一者(於第7圖的實施例中為干擾脈衝P232)之間的無雜訊區間(或是低雜訊區間)長度L13。 In step S640, the touch control unit 110 estimates a noise-free interval (or from the starting point of the trigger pulse P331 to any subsequent interference pulse Pn (the interference pulse P232 in the embodiment in FIG. 7)). Low noise interval) length L13.

步驟S650中，觸控控制單元110判斷觸發脈衝P331的無雜訊區間(或是低雜訊區間)長度L13大於觸控驅動脈衝P431之脈衝長度L2，便執行步驟S670，以第7圖為例示，觸控控制單元110判斷無雜訊區間長度L13 大於脈衝長度L2，進而控制觸控驅動單元120於無雜訊區間(或是低雜訊區間)產生觸控驅動脈衝P431，並接續產生觸控驅動脈衝P432、P433，使得觸控顯示裝置100接收觸控驅動訊號Stou的時段不會受到顯示特定圖案所產生的雜訊所影響。 In step S650, the touch control unit 110 determines that the length L13 of the noise-free interval (or low-noise interval) of the trigger pulse P331 is greater than the pulse length L2 of the touch drive pulse P431, and then executes step S670, using FIG. 7 as an example. , The touch control unit 110 determines that the noise-free interval length L13 If the pulse length is greater than L2, the touch driving unit 120 is controlled to generate a touch driving pulse P431 in a no-noise interval (or a low noise interval), and subsequently generate touch driving pulses P432 and P433, so that the touch display device 100 receives The period of the touch driving signal Stou is not affected by the noise generated by displaying a specific pattern.

值得一提的是，脈衝長度L2可以指的是觸控驅動單元120產生之觸控驅動脈衝Ptou所需要的最短脈衝持續時間。若是觸控驅動脈衝Ptou的持續時間低於脈衝長度L2，觸控顯示面板140之觸控輸入感測端RX將無法正確感測到是否存在觸控輸入或是觸控輸入的正確位置。於一實施例中，脈衝長度L2可以隨著觸控顯示面板140的尺寸、觸控輸入解析度或觸控輸入更新頻率而決定。 It is worth mentioning that the pulse length L2 may refer to the shortest pulse duration required for the touch driving pulse Ptou generated by the touch driving unit 120. If the duration of the touch driving pulse Ptou is shorter than the pulse length L2, the touch input sensing terminal RX of the touch display panel 140 cannot correctly detect whether there is a touch input or the correct position of the touch input. In one embodiment, the pulse length L2 may be determined according to the size of the touch display panel 140, the touch input resolution, or the touch input update frequency.

綜上所述，經由上述設置方式，本揭示內容可以在觸控顯示裝置100顯示特定圖案的時候防止顯示特定圖案所產生的雜訊影響觸控的操作。 In summary, through the above-mentioned setting method, the present disclosure can prevent noise generated by displaying a specific pattern from affecting the touch operation when the touch display device 100 displays a specific pattern.
