Description
本發明係有關於一種觸控顯示面板及其驅動方法，且特別有關於具有一般觸控功能及指紋辨識功能的內嵌式觸控顯示面板及其觸控模式的驅動方法。 The present invention relates to a touch display panel and a driving method thereof, and particularly relates to an in-cell touch display panel having a general touch function and a fingerprint recognition function and a driving method thereof.
內嵌觸控顯示面板(Touch In Display，TID)是同時具備顯示功能與觸控功能的新式整合型顯示器。電容式內嵌觸控顯示面板，若以觸控驅動信號及觸控感測信號的傳遞方式做為區分，可分為互容式與自容式。互容式的內嵌觸控顯示面板中，發出觸控驅動信號與接收觸控感測信號的路徑不同。自容式的內嵌觸控顯示面板則是發出觸控驅動信號與接收觸控感測信號的路徑相同。習知的自容式內嵌觸控顯示面板，係將共用電極分割成矩陣狀配置的複數個電極塊，每一個電極塊在顯示期間做為一般的共用電極使用，而在觸控期間則做為觸控感測電極使用，藉由檢測電極塊與外部的觸控物之間所形成的電容，來判斷觸控物的位置。 The built-in Touch In Display (TID) is a new integrated display with both display and touch functions. The capacitive in-cell touch display panel can be divided into a mutual capacitive type and a self-contained type by distinguishing the transmission mode of the touch driving signal and the touch sensing signal. In the in-line touch display panel, the path of the touch driving signal is different from the path of receiving the touch sensing signal. The self-contained in-cell touch display panel emits the same touch drive signal as the path for receiving the touch sensing signal. The conventional self-contained in-cell touch display panel divides the common electrode into a plurality of electrode blocks arranged in a matrix, and each of the electrode blocks is used as a general common electrode during display, and is used during touch control. For the touch sensing electrode, the position of the touch object is determined by detecting the capacitance formed between the electrode block and the external touch object.
分割為矩陣狀配置的複數電極塊分別會透過各別的金屬導線連接到驅動晶片。金屬導線與其他線路之間易產生耦合電容，耦合電容會造成信號變異而造成雜訊，進而影響觸控感測的精確性。此外，由於電極塊的面積大，僅能用於一般觸控感測， 無法應用於更精細的指紋辨識感測。 The plurality of electrode blocks divided into a matrix configuration are respectively connected to the driving wafer through respective metal wires. Coupling capacitance is easily generated between the metal wire and other lines, and the coupling capacitor causes signal variation and causes noise, thereby affecting the accuracy of touch sensing. In addition, due to the large area of the electrode block, it can only be used for general touch sensing. Cannot be applied to finer fingerprint recognition sensing.
本發明有鑑於上述的問題，而提供一種內嵌式觸控顯示面板及其觸控模式的驅動方法，可減少耦合電容，並同時具有觸控功能及指紋辨識功能。 In view of the above problems, the present invention provides an in-cell touch display panel and a driving method thereof, which can reduce coupling capacitance and simultaneously have a touch function and a fingerprint recognition function.

第2圖係本發明實施例的內嵌觸控顯示面板中的一個畫素的概要電路圖。在本發明中一個畫素(嚴格來說是子畫素)包括畫素電極31、第一開關元件T1、液晶顯示元件CLC、儲存電容Cst、共用電極32、第二開關元件T2。第一開關元件T1及第二開關元件T2例如是薄膜電晶體。在第2圖中，液晶顯示元件CLC以連接於畫素電極31與共用電極32之間的電容來表示，儲存電容Cst亦為連接於畫素電極31與共用電極32之間的電容。第一開關元件T1配置於畫素電極31與資料線24之間，其控制端子(閘極)連接至閘極線25。第二開關元件T2配置於共用電極32與共用電極線27之間，其控制端子連接至次閘極線26。 2 is a schematic circuit diagram of one pixel in an in-cell touch display panel according to an embodiment of the present invention. In the present invention, one pixel (strictly speaking, a sub-pixel) includes a pixel electrode 31, a first switching element T1, a liquid crystal display element C LC , a storage capacitor Cst, a common electrode 32, and a second switching element T2. The first switching element T1 and the second switching element T2 are, for example, thin film transistors. In FIG. 2, the liquid crystal display element C LC is represented by a capacitance connected between the pixel electrode 31 and the common electrode 32, and the storage capacitor Cst is also a capacitance connected between the pixel electrode 31 and the common electrode 32. The first switching element T1 is disposed between the pixel electrode 31 and the data line 24, and its control terminal (gate) is connected to the gate line 25. The second switching element T2 is disposed between the common electrode 32 and the common electrode line 27, and its control terminal is connected to the secondary gate line 26.
以下說明本發明的內嵌觸控顯示面板中，一個畫素操作於顯示模式與觸控模式的驅動方式。第3A圖係第2圖的畫素操作於顯示模式的示意圖。第3B圖係第2圖的畫素操作於觸控模式的示意圖。當操作於顯示模式時，如第3A圖所示，第二開關元件T2開啟(ON)，共用電極32與共用電極線27導通，共用電極線27提供一固定的共用電壓(Vcom)至共用電極32，此時第一開關元件T1開啟(ON)，畫素電極31與資料線24導通，資料線24將顯 示資料信號Vdata送至畫素電極31，以更新顯示畫面。當操作於觸控模式時，如第3B圖所示，第二開關元件T2關閉(OFF)，共用電極32與共用電極線27之間無法導通，共用電極32處於浮動(flaoting)電位，此時第一開關元件T1開啟(ON)，畫素電極31與資料線24導通，資料線24將觸控驅動信號VT傳送至畫素電極31，並從畫素電極31接收觸控感測信號VR的感測結果，以判斷觸碰與否。 Hereinafter, in the in-cell touch display panel of the present invention, a pixel is operated in a display mode and a touch mode. Fig. 3A is a schematic diagram of the pixel operation of Fig. 2 in the display mode. FIG. 3B is a schematic diagram of the pixel operation of FIG. 2 in the touch mode. When operating in the display mode, as shown in FIG. 3A, the second switching element T2 is turned "ON", the common electrode 32 is turned on with the common electrode line 27, and the common electrode line 27 supplies a fixed common voltage (Vcom) to the common electrode. 32. At this time, the first switching element T1 is turned on (ON), the pixel electrode 31 is turned on with the data line 24, and the data line 24 is displayed. The data signal Vdata is sent to the pixel electrode 31 to update the display screen. When operating in the touch mode, as shown in FIG. 3B, the second switching element T2 is turned off (OFF), the common electrode 32 and the common electrode line 27 are not turned on, and the common electrode 32 is at a flacing potential. The first switching element T1 is turned on (ON), the pixel electrode 31 is electrically connected to the data line 24, the data line 24 transmits the touch driving signal VT to the pixel electrode 31, and the touch sensing signal VR is received from the pixel electrode 31. Sensing the result to determine whether it is touched or not.
在上述驅動方式中，每個畫素電極31都會收送觸控驅動信號VT及觸控感測信號VR，因此畫素電極31在觸控模式下相當於一個最小單位的觸控感測電極，由於感測面積遠比習知技術以一個電極塊來做為觸控感測電極小，因此可以做更精細的觸控感測。另外，當顯示資料信號Vdata透過資料線24輸入畫素電極31時，共用電極32維持定值的共用電壓Vcom。此時，畫素電極31與共用電極32之間的壓差會控制液晶顯示元件CLC顯示特定的灰階。當轉換為觸控模式時，由於共用電極32的電位為浮動狀態(floating)，也就是非定值，所以即使觸控驅動信號VT及觸控感測信號VR透過資料線24輸入畫素電極31而改變了畫素電極31的原本的灰階電壓，但畫素電極31與共用電極32之間的壓差仍可因為耦合效應而維持不變，因此液晶顯示元件CLC仍可維持原來顯示的灰階，並不會因為觸控而影響顯示畫面。 In the above driving mode, each pixel electrode 31 receives the touch driving signal VT and the touch sensing signal VR, so that the pixel electrode 31 corresponds to a minimum unit of the touch sensing electrode in the touch mode. Since the sensing area is much smaller than the conventional one with the electrode block as the touch sensing electrode, finer touch sensing can be performed. Further, when the display material signal Vdata is input to the pixel electrode 31 through the data line 24, the common electrode 32 maintains the constant value of the common voltage Vcom. At this time, the pressure difference between the pixel electrode 31 and the common electrode 32 controls the liquid crystal display element C LC to display a specific gray scale. When the switch to the touch mode, since the potential of the common electrode 32 is floating, that is, a non-fixed value, even if the touch driving signal VT and the touch sensing signal VR are input to the pixel electrode 31 through the data line 24 The original gray scale voltage of the pixel electrode 31 is changed, but the voltage difference between the pixel electrode 31 and the common electrode 32 can still be maintained due to the coupling effect, so the liquid crystal display element C LC can maintain the original display. Grayscale does not affect the display due to touch.
第4圖係顯示第2圖的畫素在顯示模式與觸控模式驅動下的時序示意圖。在此假設第一開關元件T1及第二開關元件T2的控制端子處於高電位時為開啟(ON)，處於低電位時為關閉(OFF)來做說明(例如N型電晶體)。然而，依據開關元件的類型，開關 元件也可以在低電位下開啟，在高電位下關閉(例如P型電晶體)。如第4圖所示，在顯示模式下，閘極線25的電位在高電位與低電位之間作切換，閘極線25在高電位時，第一開關T1開啟，將顯示資料信號Vdata電位寫入畫素電極31，切換成低電位時，第一開關T1關閉，畫素電極31維持資料信號Vdata電位。顯示模式下，次閘極線26維持高電位，因此第二開關元件T2保持開啟，使共用電極32維持定值的共同電壓Vcom電位。 Fig. 4 is a timing chart showing the pixel of Fig. 2 driven by the display mode and the touch mode. Here, it is assumed that the control terminals of the first switching element T1 and the second switching element T2 are turned "ON" when they are at a high potential, and are turned off (OFF) when they are at a low level (for example, an N-type transistor). However, depending on the type of switching element, the switch The component can also be turned on at a low potential and turned off at a high potential (for example, a P-type transistor). As shown in Fig. 4, in the display mode, the potential of the gate line 25 is switched between a high potential and a low potential. When the gate line 25 is at a high potential, the first switch T1 is turned on, and the data signal Vdata potential is displayed. When the pixel electrode 31 is written and switched to a low potential, the first switch T1 is turned off, and the pixel electrode 31 maintains the potential of the data signal Vdata. In the display mode, the secondary gate line 26 maintains a high potential, so the second switching element T2 remains on, and the common electrode 32 maintains a constant common voltage Vcom potential.
在觸控模式下，假設為特定區域的閘極線同時全掃描的掃描方式(即第三掃描方式，具體特徵詳述於後)，閘極線25會維持高電位以開啟第一開關T1，資料線24在此期間傳送與接收多個觸控驅動信號VT及觸控感測信號VR(圖中振幅小於資料信號而頻率高於資料信號的多個脈波)。在此期間，次閘極線26則一直維持低電位，第二開關元件T2關閉，使共用電極32的電位處於浮動的狀態。 In the touch mode, assuming that the gate line of a specific area is simultaneously scanned by the full scan (ie, the third scan mode, the specific features are detailed later), the gate line 25 maintains a high potential to turn on the first switch T1. During this period, the data line 24 transmits and receives a plurality of touch driving signals VT and touch sensing signals VR (the amplitude of the figure is smaller than the data signal and the frequency is higher than the plurality of pulse signals of the data signal). During this period, the secondary gate line 26 is maintained at a low potential, and the second switching element T2 is turned off, so that the potential of the common electrode 32 is in a floating state.
兩顯示模式時段之間具有空白期間(blanking period)，觸控模式時段可位於空白期間中，並與顯示模式時段具有轉換期間做為之間的間隔，於轉換期間內，次閘極線26由高電位切換至低電位，第二開關元件T2關閉使共用電極32的電位處於浮動的狀態，資料線24在此期間不作動。 There is a blanking period between the two display mode periods, the touch mode period may be in the blank period, and there is an interval between the transition period and the display mode period, during which the secondary gate line 26 is The high potential is switched to the low potential, and the second switching element T2 is turned off to bring the potential of the common electrode 32 to a floating state, and the data line 24 is not operated during this period.
透過以上的方式，本發明可利用共用電極32電位處於浮動狀態時，透過資料線24對畫素電極31充放電，來感測觸控位置。需要注意的是，在第1圖到第4圖的實施例中，各畫素內均配置了一個第二開關元件T2來控制共用電極32的電壓。但第二開關元件T2也可以整合並設置在畫素以外的位置，例如一列畫素之 第二開關元件T2可整合為一，並位於顯示區域21非畫素位置，或者周邊區域29。另外，若是傳送信號給共用電極線27的觸控顯示控制電路28具備提供共用電極線27電位為浮動狀態的能力，第二開關元件T2以及次閘極線26也可以省略。 In the above manner, the present invention can sense the touch position by charging and discharging the pixel electrode 31 through the data line 24 when the potential of the common electrode 32 is in a floating state. It should be noted that in the embodiments of FIGS. 1 to 4, a second switching element T2 is disposed in each pixel to control the voltage of the common electrode 32. However, the second switching element T2 can also be integrated and placed at a position other than the pixel, such as a column of pixels. The second switching element T2 can be integrated into one and located at a non-pixel position of the display area 21, or a peripheral area 29. Further, if the touch display control circuit 28 that transmits a signal to the common electrode line 27 has the capability of providing the potential of the common electrode line 27 in a floating state, the second switching element T2 and the secondary gate line 26 may be omitted.
本發明上述的內嵌觸控顯示面板可採用畫素電極31與共用電極32皆位於同一側基板的邊緣電場式(fringe field switching，FFS)電極架構，例如頂部畫素電極式(Top Pixel，畫素電極在上鄰近液晶層，共用電極在下鄰近薄膜電晶體)的架構或頂部共同電極式(Top Com，共用電極在上鄰近液晶層，畫素電極在下鄰近薄膜電晶體)的架構。在頂部畫素電極式的架構下，畫素電極31上方無共用電極32的屏蔽，可直接感測觸控物體。在頂部共同電極式的架構下，畫素電極雖被共用電極32所覆蓋，然而共用電極32在觸控模式為浮動電位，因此共用電極32會受到畫素電極31的耦合效應所影響，使其電壓與畫素電極31的電壓一起同時變化，因此同樣可以感應觸控物體。第5A圖及第5B圖分別為本發明使用頂部畫素電極式架構與頂部共同電極式架構下的一個畫素的上視概略圖。從圖中可見，無論是頂部畫素電極架構或頂部共同電極式架構，兩者具有共同的特徵，也就是每個畫素都有一塊獨立的共用電極32，使得每個畫素的共用電極32可以維持彼此獨立的浮動狀態，因此可將一個畫素做為最小的觸控感測單元。另外，由於畫素電極31與共用電極32在垂直與水平方向上與資料線24、閘極線25、次閘極線26、共用電極線27重疊的比例降低，因此可以減少觸控感測電極與其他線路之間的耦合效應。 The in-cell touch display panel of the present invention can adopt a fringe field switching (FFS) electrode structure in which the pixel electrode 31 and the common electrode 32 are both located on the same side substrate, for example, a top pixel electrode type (Top Pixel, drawing The upper electrode is adjacent to the liquid crystal layer, the common electrode is adjacent to the thin film transistor, or the top common electrode type (Top Com, the common electrode is adjacent to the liquid crystal layer, and the pixel electrode is adjacent to the thin film transistor). Under the top pixel electrode structure, there is no shielding of the common electrode 32 above the pixel electrode 31, and the touch object can be directly sensed. In the top common electrode type structure, the pixel electrode is covered by the common electrode 32, but the common electrode 32 is a floating potential in the touch mode, so the common electrode 32 is affected by the coupling effect of the pixel electrode 31, so that The voltage changes simultaneously with the voltage of the pixel electrode 31, so that the touch object can also be sensed. 5A and 5B are top plan views of a pixel using a top pixel electrode structure and a top common electrode structure, respectively. As can be seen from the figure, both the top pixel structure or the top common electrode architecture have a common feature, that is, each pixel has a separate common electrode 32 such that the common electrode 32 of each pixel The floating state can be maintained independently of each other, so one pixel can be used as the smallest touch sensing unit. In addition, since the ratio of the pixel electrode 31 and the common electrode 32 overlapping the data line 24, the gate line 25, the second gate line 26, and the common electrode line 27 in the vertical and horizontal directions is reduced, the touch sensing electrode can be reduced. Coupling effect with other lines.
接著，說明本發明實施例的內嵌觸控顯示面板在觸 控模式下的掃描方式。本發明可提供三種觸控模式的掃描方式：第一掃描方式、第二掃描方式、第三掃描方式。 Next, the in-cell touch display panel of the embodiment of the present invention is touched. Scan mode in control mode. The invention can provide three scanning modes of the touch mode: a first scanning mode, a second scanning mode, and a third scanning mode.
第一掃描方式是閘極線25從面板的上方至下方逐條掃描(從閘極線25-1掃描至閘極線25-n)。同時，在每條閘極線25被掃描的期間中，觸控驅動信號VT由資料線驅動電路22經由資料線24傳送至畫素電極31，並由畫素電極31經由資料線24接收觸控感測信號VR，以完成掃描觸控點的動作。這種掃描方式，可將顯示區域21內所有觸控點，依時序進行掃描。且每個畫素是一個觸控感測單元，因此可進行精細的指紋辨識功能，例如多點指紋掃描或掌紋掃描等。然而，這種掃描方式需要較長的掃描時間，所以較適合應用於觸控產品的開機畫面，或者是顯示特殊影像的期間；在此期間內，面板驅動顯示時間全部轉換為觸控掃描時間。 The first scanning mode is that the gate lines 25 are scanned one by one from the top to the bottom of the panel (scanning from the gate line 25-1 to the gate line 25-n). Meanwhile, during the period in which each gate line 25 is scanned, the touch driving signal VT is transmitted from the data line driving circuit 22 to the pixel electrode 31 via the data line 24, and the pixel is received by the pixel electrode 31 via the data line 24. The signal VR is sensed to complete the action of scanning the touch point. This scanning method can scan all the touch points in the display area 21 in time series. Each pixel is a touch sensing unit, so fine fingerprint recognition functions such as multi-point fingerprint scanning or palmprint scanning can be performed. However, this scanning method requires a long scanning time, so it is more suitable for the startup screen of the touch product or the period during which the special image is displayed; during this period, the panel driving display time is all converted into the touch scanning time.
第二掃描方式是將顯示區域21在例如行方向(column)上事先分割為複數個區域(例如分成20~30區)，每一區內的閘極線25的數目並無限制，可為一或一以上的數目，然後對選定的區域中的閘極線25進行逐條循序的觸控掃描。由於觸控感測只在選定的區域進行，因此掃描時間較第一掃描方式短，且在選定的區域內仍然為逐條掃描，因此在選定的區域內同樣可以進行指紋辨識功能。而上述選定的區域可以事先決定，在進入指紋辨識功能時，使畫面中顯示特定的方塊來告知使用者指紋辨識的區域。又或者是，先用粗略的掃描方式(如後所述的第三掃描方式)找出觸控點所在的位置，再將該位置所在的區域做為選定的區域來進行逐條掃描。 The second scanning method is to divide the display area 21 into a plurality of areas (for example, 20 to 30 areas) in advance, for example, in a row direction, and the number of gate lines 25 in each area is not limited, and may be one. Or more than one number, then step-by-step touch scanning of the gate lines 25 in the selected area. Since the touch sensing is performed only in the selected area, the scanning time is shorter than the first scanning mode, and the scanning is still performed one by one in the selected area, so the fingerprint identification function can also be performed in the selected area. The selected area can be determined in advance, and when the fingerprint recognition function is entered, a specific square is displayed on the screen to inform the user of the area of fingerprint recognition. Alternatively, the location of the touch point is found by a rough scan method (such as the third scan mode described later), and the area where the position is located is used as the selected area for scanning one by one.
第三掃描方式同樣是將顯示區域21在例如行方向 (column)上事先分割為複數個區域(例如分成20~30區)，但當一個區域進行觸控感測時，該區域內的全部閘極線25在同一時間被掃描。具體來說，假設一個區域內有一百條閘極線25，當這個區域進行觸控感測時，這一百條閘極線25會同時開啟區域內所有的第一開關元件T1來進行觸控感測。第7圖是使用本發明的第三掃描方式進行觸控感測的示意圖。如第7圖所示，F表示手指觸控的範圍，假設顯示區域21中由上至下分割為次區域A1、A2、A3、…，各個次區域A1、A2、A3、…由上往下依序進行觸控感測。於區域A3進行觸控感測感測時，就會感測到觸控物的存在。此時由於次區域A3內的閘極線25是全部開啟，因此一個有效的觸控感測單元，如第6圖右方的放大圖所示，可分別是虛線框起來的範圍Sj、Sj+1、Sj+2。觸控感測單元Sj是次區域A3內連接到資料線24-j的全部的畫素，同理，觸控感測單元Sj+1是次區域A3內連接到資料線24-j+1的全部的畫素，觸控感測單元Sj+2是次區域A3內連接到資料線24-j+2的全部的畫素。在本掃描方式中，由於有效的觸控感測單元的面積較大，因此觸控感測的解析度較低，適合應用於一般的觸控功能。此外，各個區域與區域之間的觸控感測，除了依序(由面板上方至面板下方，所有區域均開啟一次)進行觸控感測外，也可隨機開啟各個區域(將所有區域隨機開啟一次)，又或者可以只對特定區域(只掃描面板固定區域)進行觸控感測。 The third scanning method is also to display the display area 21 in, for example, the row direction. (column) is divided into a plurality of regions (for example, divided into 20 to 30 regions), but when one region performs touch sensing, all gate lines 25 in the region are scanned at the same time. Specifically, it is assumed that there are one hundred gate lines 25 in one area. When the area is touch-sensed, the hundred gate lines 25 simultaneously open all the first switching elements T1 in the area to touch. Control sensing. FIG. 7 is a schematic diagram of touch sensing using the third scanning method of the present invention. As shown in FIG. 7, F represents the range of finger touch, and it is assumed that the display area 21 is divided into sub-areas A1, A2, A3, ... from top to bottom, and each sub-area A1, A2, A3, ... is from top to bottom. Touch sensing is performed sequentially. When the touch sensing is performed in the area A3, the presence of the touch object is sensed. At this time, since the gate lines 25 in the sub-area A3 are all turned on, an effective touch sensing unit, as shown in the enlarged view on the right side of FIG. 6, may be the range of the dotted line, Sj, Sj+, respectively. 1, Sj+2. The touch sensing unit Sj is all the pixels connected to the data line 24-j in the sub-area A3. Similarly, the touch sensing unit Sj+1 is connected to the data line 24-j+1 in the sub-area A3. For all the pixels, the touch sensing unit Sj+2 is the entire pixel connected to the data line 24-j+2 in the sub-area A3. In this scanning mode, since the effective touch sensing unit has a large area, the touch sensing has a low resolution and is suitable for a general touch function. In addition, the touch sensing between each area and the area is performed in addition to the touch sensing in sequence (from the top of the panel to the lower part of the panel, all areas are turned on once), and each area can be randomly opened (all areas are randomly opened) Once, it is also possible to perform touch sensing only on a specific area (only scanning the fixed area of the panel).
在上述第三掃描方式中，可依時序開啟複數閘極線25與複數資料線24，來傳遞觸控驅動訊號VT與接收觸控感測訊號VR，來達到多點觸控與多點掃描的功能。 In the above third scanning mode, the plurality of gate lines 25 and the plurality of data lines 24 can be turned on according to the timing to transmit the touch driving signal VT and the receiving touch sensing signal VR to achieve multi-touch and multi-point scanning. Features.
以下簡單說明，本發明如何選用上述三種掃描方式。 第7圖係本發明的觸控顯示面板的觸控模式的掃描方式選擇方法的示意圖。如第7圖所示，在步驟S1，觸控顯示面板進入觸控模式，觸控模式下可選擇執行指紋辨識功能或普通觸控功能。當系統執行指紋辨識功能(步驟S2)時，可選擇循序掃描閘極線25的方式(步驟S3)。接著，確認是否只在特定的區域進行指紋辨識(步驟S4)，若是，則使用第二掃描方式，在特定的區域進行循序掃描(步驟S5)。若否，則使用第一掃描方式，對整個顯示區域進行循序掃描(步驟S6)。另一方面，當系統執行普通觸控功能時(步驟S7)，因為不需要精細感測，所以顯示區域會分為多個區域來進行觸控感測(步驟S8)，並且使用第三掃描方式，當每個區域進行觸控感測時，該區域內的全部閘極線同時掃描(步驟S9)。 The following briefly describes how the present invention selects the above three scanning methods. FIG. 7 is a schematic diagram of a scanning mode selection method of a touch mode of the touch display panel of the present invention. As shown in FIG. 7, in step S1, the touch display panel enters a touch mode, and in the touch mode, a fingerprint recognition function or an ordinary touch function can be selected. When the system performs the fingerprint recognition function (step S2), the manner of sequentially scanning the gate lines 25 can be selected (step S3). Next, it is confirmed whether fingerprint recognition is performed only in a specific area (step S4), and if so, the second scanning method is used to perform sequential scanning in a specific area (step S5). If not, the entire scanning area is sequentially scanned using the first scanning method (step S6). On the other hand, when the system performs the normal touch function (step S7), since fine sensing is not required, the display area is divided into a plurality of areas for touch sensing (step S8), and the third scanning mode is used. When each area performs touch sensing, all gate lines in the area are simultaneously scanned (step S9).
藉由適當地選擇上述的三種掃描方式，本發明不但具備只需粗略掃描的一般觸控功能，更具備需要精細掃描的指紋辨識功能。 By appropriately selecting the above three scanning modes, the present invention not only has a general touch function that requires a rough scan, but also has a fingerprint recognition function that requires fine scanning.
雖然第4圖已說明了觸控模式是在顯示模式停止期間下進行，但並未說明更具體的時序關係。以下將說明觸控模式與顯示模式的時序關係。第8圖顯示本發明的觸控模式與顯示模式的時序圖。根據上述三種掃描方式所需的時間及特性的不同，觸控模式與顯示模式可有如第8A、8B、8C圖所示的三種搭配。在此假設顯示器是以60Hz驅動，則一個圖框期間(1frame)相當於16.6ms。第8A至第8C圖中高位準表示該模式啟動(on)，低位準表示該模式關閉(off)。首先，如第8A圖所示，在某一個圖框期間全部執行觸控模式，而不進入顯示模式，此時觸控模式會採用 上述第一掃描方式。由於上述第一掃描方式要對整個面板進行逐條掃描，因此花費較多的時間。在第8A圖當中，就選擇一整個圖框期間來執行觸控模式。於其他實施例中，此掃描方式所需時間，可為一或一以上的圖框時間。接著，如第8B圖所示，觸控模式可在每一個圖框期間內的空白期間進行。由於每個圖框之間都會有不驅動顯示區域的空白期間，因此觸控模式可以在這段期間進行。此時觸控模式可採用上述第二掃瞄方式或第三掃描方式，對一個或複數個以上的區域進行該區域的逐條掃描或同步掃描。另外，如第8C圖所示，顯示模式與觸控模式皆分區域執行。當顯示區域例如第7圖所示由上方往下分割為次區域A1、A2、A3、…時，顯示模式啟動對次區域A1進行掃描，完成後觸控模式啟動，對次區域A1進行掃描。接著，顯示模式再啟動對區域A2進行掃描，完成後觸控模式啟動，對次區域A2進行掃描，依此類推，直到整個顯示區域都完成一次顯示模式的驅動與觸控模式的驅動為止。此時觸控模式可採用上述第二掃瞄方式或第三掃描方式，對一個或複數個以上的區域進行該區域的逐條掃描或同時掃描。 Although FIG. 4 has illustrated that the touch mode is performed during the stop of the display mode, a more specific timing relationship is not illustrated. The timing relationship between the touch mode and the display mode will be described below. Fig. 8 is a timing chart showing the touch mode and the display mode of the present invention. According to the time and characteristics required for the above three scanning modes, the touch mode and the display mode may have three combinations as shown in FIGS. 8A, 8B, and 8C. It is assumed here that the display is driven at 60 Hz, and one frame period (1 frame) is equivalent to 16.6 ms. The high level in Figures 8A through 8C indicates that the mode is on (on) and the low level indicates that the mode is off. First, as shown in FIG. 8A, during all the frames, the touch mode is executed without entering the display mode, and the touch mode is adopted. The first scanning method described above. Since the first scanning method scans the entire panel one by one, it takes a lot of time. In Fig. 8A, an entire frame period is selected to execute the touch mode. In other embodiments, the time required for this scanning mode may be one or more frame times. Next, as shown in FIG. 8B, the touch mode can be performed during the blank period in each frame period. Since each frame has a blank period that does not drive the display area, the touch mode can be performed during this period. In this case, the touch mode may use the second scanning mode or the third scanning mode to perform one-by-one scanning or synchronous scanning of the area for one or more areas. In addition, as shown in FIG. 8C, both the display mode and the touch mode are performed in regions. When the display area is divided into the sub-areas A1, A2, A3, ... from the top to the bottom, for example, as shown in FIG. 7, the display mode starts scanning the sub-area A1, and after the completion, the touch mode is started, and the sub-area A1 is scanned. Then, the display mode is restarted to scan the area A2, after the completion of the touch mode, the sub-area A2 is scanned, and so on, until the display mode is driven and the touch mode is driven in the entire display area. In this case, the touch mode may use the second scanning mode or the third scanning mode to perform one-by-one scanning or simultaneous scanning of the area on one or more areas.
接著，說明用以執行上述三種觸控掃描方式的閘極電路的具體實施方式。第9圖係本發明的閘極驅動電路的概要示意圖。第11圖係本發明的閘極驅動電路23的基本電路圖。如第9圖所示，閘極驅動電路23具有複數個閘極線驅動區塊GOP1、GOP2、…(為了方便說明第9圖僅顯示兩個閘極線驅動區塊GOP1、GOP2)。每一個閘極線驅動區塊，例如：閘極線驅動區塊GOP1具有例如k個串級連接的閘極線驅動單元U1、U2、…、Uk，用來驅動例如k條閘極線25-1、25-2、…、25-k。每一個閘極線驅動單元，以閘 極線驅動單元U1為例，會具有如第10圖所示的基本電路架構，至少具有觸發信號輸入端D、時脈信號輸入端CK、與輸出端O。觸發信號輸入端D會輸入上一級的閘極線驅動單元的輸出端O所輸出的信號，然而，第一級的閘極線驅動單元U1的觸發信號輸入端D，會經由觸發信號線L2輸入觸發信號STV。時脈信號輸入端CK會輸入時脈信號。輸出端O會輸出掃描信號給閘極線25-1。 Next, a specific embodiment of a gate circuit for performing the above three touch scanning methods will be described. Fig. 9 is a schematic diagram showing the gate drive circuit of the present invention. Fig. 11 is a basic circuit diagram of the gate driving circuit 23 of the present invention. As shown in Fig. 9, the gate driving circuit 23 has a plurality of gate line driving blocks GOP1, GOP2, ... (only two gate driving blocks GOP1, GOP2 are shown in Fig. 9 for convenience of explanation). Each of the gate line driving blocks, for example, the gate line driving block GOP1 has, for example, k cascade-connected gate line driving units U1, U2, ..., Uk for driving, for example, k gate lines 25- 1, 25-2, ..., 25-k. Each gate line drive unit As an example, the polar line driving unit U1 has a basic circuit structure as shown in FIG. 10, and has at least a trigger signal input terminal D, a clock signal input terminal CK, and an output terminal O. The trigger signal input terminal D inputs the signal outputted from the output terminal O of the gate drive unit of the previous stage. However, the trigger signal input terminal D of the gate drive unit U1 of the first stage is input via the trigger signal line L2. Trigger signal STV. The clock signal input terminal CK inputs the clock signal. The output terminal O outputs a scan signal to the gate line 25-1.
在本發明的實施例當中，設置了三種開關SW1、SW2、SW3於閘極驅動電路23當中，藉此來達成前述的三種觸控掃描方式。開關SW1設置於相鄰的閘極線驅動區塊之間，以閘極線驅動區塊GOP1與GOP2為例，開關SW1的一端連接到閘極線驅動區塊GOP1中最後一級的閘極線驅動單元Uk的輸出端O，另一端連接個閘極線驅動區塊GOP2中第一級的閘極線驅動單元Uk+1的觸發信號輸入端D。開關SW1的目的，在於控制閘極線驅動區塊GOP2，是否接續在閘極線驅動區塊GOP1後驅動，或者兩者為相互獨立地驅動。開關SW2連接到一條外部的觸發信號線與各個閘極線驅動區塊第一級閘極線驅動單元的觸發信號輸入端之間。以第9圖為例，開關SW2連接外部的觸發信號線L3與閘極線驅動區塊GOP2第一級的閘極線驅動單元Uk+1的觸發信號輸入端D。第一個閘極線驅動單元GOP1不需要做觸發信號的切換，因此可以不用設置開關SW2。閘極線驅動單元GOP1第一級的閘極線驅動單元U1的觸發信號輸入端D可直接連接到一條觸發信號線L2。需注意的是為了使各個閘極線驅動區塊可以獨立地驅動，各個閘極線驅動區塊會分別連到不同的觸發信號線。另外，每個閘極線驅動單元中，會有一開關SW3連接觸發信號輸入端D與時脈信號輸入端CK，且所有 的開關SW3會統一由一條信號線L1所控制。開關SW3用來控制閘極線驅動區塊中，所有閘極線驅動單元是逐條輸出掃描信號還是同步輸出掃描信號。 In the embodiment of the present invention, three types of switches SW1, SW2, and SW3 are provided in the gate driving circuit 23, thereby achieving the above three touch scanning modes. The switch SW1 is disposed between adjacent gate driving blocks, taking the gate driving blocks GOP1 and GOP2 as an example, and one end of the switch SW1 is connected to the gate driving of the last stage of the gate driving block GOP1. The output terminal O of the unit Uk is connected to the trigger signal input terminal D of the gate line driving unit Uk+1 of the first stage of the gate line driving block GOP2. The purpose of the switch SW1 is to control whether the gate line driving block GOP2 is driven after being connected to the gate line driving block GOP1, or both are driven independently of each other. The switch SW2 is connected between an external trigger signal line and a trigger signal input terminal of the first-stage gate line driving unit of each gate line driving block. Taking FIG. 9 as an example, the switch SW2 is connected to the external trigger signal line L3 and the trigger signal input terminal D of the gate line driving unit Uk+1 of the first stage of the gate line driving block GOP2. The first gate line driving unit GOP1 does not need to perform switching of the trigger signal, so the switch SW2 may not be provided. The trigger signal input terminal D of the gate line driving unit U1 of the first stage of the gate line driving unit GOP1 can be directly connected to one trigger signal line L2. It should be noted that in order to enable the respective gate line driving blocks to be driven independently, the respective gate line driving blocks are respectively connected to different trigger signal lines. In addition, in each of the gate line driving units, a switch SW3 is connected to the trigger signal input terminal D and the clock signal input terminal CK, and all The switch SW3 is uniformly controlled by one signal line L1. The switch SW3 is used to control the gate line driving block, and all the gate line driving units output the scanning signals one by one or the synchronous output scanning signals.
當觸控模式要採用第一掃描方式，為了將整個顯示區域的閘極線做逐條掃描。會將開關SW1開啟，每個閘極線驅動元件區塊在前一級的閘極線驅動區塊掃描作動後，將接續進行掃描，此時開關SW2及SW3關閉。三者開關的作動使得閘極線驅動區塊內的閘極線為逐條掃描。因此，閘極線將從顯示區域中第一條掃描到最後一條。 When the touch mode is to adopt the first scanning mode, the gate lines of the entire display area are scanned one by one. The switch SW1 is turned on, and each gate line driving element block is scanned after the gate driving block of the previous stage is scanned, and the switches SW2 and SW3 are turned off. The actuation of the three switches causes the gate lines in the gate drive block to be scanned one by one. Therefore, the gate line will scan from the first to the last in the display area.
當觸控模式要採用第二掃描方式，為了進行分區逐條掃描，開關SW1關閉使各個閘極線驅動區塊彼此相互獨立。開關SW2打開，使各個閘極線驅動區塊接收個別獨立的觸發信號。開關SW3關閉，使各個閘極線驅動區塊內的閘極線為逐條掃描。 When the touch mode is to adopt the second scanning mode, in order to perform the partition-by-slice scanning, the switch SW1 is turned off to make the respective gate line driving blocks independent of each other. The switch SW2 is turned on, so that each gate line driving block receives an individual independent trigger signal. The switch SW3 is turned off, so that the gate lines in the respective gate line driving blocks are scanned one by one.
當觸控模式要採用第二掃描方式，為了進行分區逐條掃描，開關SW1關閉使各個閘極線驅動區塊彼此相互獨立。開關SW2打開，使各個閘極線驅動區塊接收獨立的觸發信號。開關SW3關閉，使各個閘極線驅動區塊內的閘極線為逐條掃描。由於每個閘極線驅動區塊所接收的觸發信號可分別控制，因此可以選擇只驅動特定的閘極線驅動區塊中的閘極線。 When the touch mode is to adopt the second scanning mode, in order to perform the partition-by-slice scanning, the switch SW1 is turned off to make the respective gate line driving blocks independent of each other. The switch SW2 is turned on, so that each gate line driving block receives an independent trigger signal. The switch SW3 is turned off, so that the gate lines in the respective gate line driving blocks are scanned one by one. Since the trigger signals received by each of the gate line driving blocks can be separately controlled, it is possible to select to drive only the gate lines in the specific gate line driving block.
當觸控模式要採用第三掃描方式，為了進行分區全閘極線同時掃描，開關SW1關閉使各個閘極線驅動區塊彼此相互獨立。開關SW2打開，使各個閘極線驅動區塊接收獨立的觸發信號。開關SW3也打開，使各個閘極線驅動區塊內的全部閘極線同時輸出掃描信號。同樣地，由於每個閘極線驅動區塊所接收的觸 發信號可分別控制，因此可以選擇只驅動特定的閘極線驅動區塊中的閘極線。 When the touch mode is to adopt the third scanning mode, in order to perform simultaneous scanning of the partitioned full gate lines, the switch SW1 is turned off to make the respective gate line driving blocks independent of each other. The switch SW2 is turned on, so that each gate line driving block receives an independent trigger signal. The switch SW3 is also turned on, so that all the gate lines in each gate line driving block simultaneously output scan signals. Similarly, due to the touch received by each gate drive block The signal can be controlled separately, so it is possible to choose to drive only the gate lines in a particular gate drive block.
藉由將上述的開關設置於非晶矽、或多晶矽、或氧化物半導體為主動層之薄膜電晶體的閘極驅動電路中，可以確實地實現本發明在觸控模式下的三種掃描方式。 By providing the above-mentioned switch in a gate driving circuit of a thin film transistor in which an amorphous germanium or a polycrystalline germanium or an oxide semiconductor is an active layer, three scanning modes of the present invention in the touch mode can be surely realized.
最後，說明本發明的資料線輸出觸控信號亦可做同時或分區輸出。第11圖係顯示本發明的資料線分區輸出電路的概要架構圖。第11圖的電路可形成於面板上，位於例如本案第1圖的顯示區域21與資料驅動電路22之間的位置。如第12圖所示，複數條相鄰的資料線可分為一組，例如每一組有3條相鄰的資料線。每一組中具有三個開關，每一個開關的一端連接到一條資料線，另一端共通連接到資料驅動電路的一個腳位。而這三個開關的控制端子會分別連接到三條控制信號線。以第1組為例，共有三條資料線24-1、24-2、24-3以及三個連接到這三條資料線的開關SW4、SW5、SW6。這三個開關SW4、SW5、SW6的另一端共通連接到資料驅動電路(例如第1圖的資料驅動電路22)的一個腳位IC pin1，且這三個開關SW4、SW5、SW6的控制端子分別連接到三條控制信號線M1、M2、M3。同樣地，第2組的配置與第1組相同，惟三個開關SW4、SW5、SW6的另一端共通連接到資料驅動電路的另一個腳位IC pin2。 Finally, the data line output touch signal of the present invention can also be used for simultaneous or partial output. Figure 11 is a schematic block diagram showing the data line partition output circuit of the present invention. The circuit of Fig. 11 can be formed on the panel, for example, at a position between the display area 21 and the material drive circuit 22 of Fig. 1 of the present invention. As shown in Fig. 12, a plurality of adjacent data lines can be grouped into one group, for example, each group has three adjacent data lines. There are three switches in each group, one end of each switch is connected to one data line, and the other end is commonly connected to one pin of the data driving circuit. The control terminals of these three switches are respectively connected to three control signal lines. Taking the first group as an example, there are three data lines 24-1, 24-2, 24-3 and three switches SW4, SW5, and SW6 connected to the three data lines. The other ends of the three switches SW4, SW5, and SW6 are commonly connected to one pin IC pin1 of the data driving circuit (for example, the data driving circuit 22 of FIG. 1), and the control terminals of the three switches SW4, SW5, and SW6 are respectively Connected to three control signal lines M1, M2, M3. Similarly, the configuration of the second group is the same as that of the first group, but the other ends of the three switches SW4, SW5, and SW6 are commonly connected to the other pin IC pin2 of the data driving circuit.
藉由上述的架構，主要可採取三種方式來輸出資料線的觸控驅動信號VT。第一種是控制信號線M1、M2、M3同時將全部的開關開啟，且資料驅動電路腳位Pin1、IC Pin 2、IC Pin3同時送出觸控驅動信號VT；之後，再由資料線，資料驅動電路經 由腳位Pin1、IC Pin 2、IC Pin3，接收觸控感測訊號VR。 With the above architecture, the touch driving signal VT of the data line can be mainly output in three ways. The first type is that the control signal lines M1, M2, and M3 simultaneously turn all the switches on, and the data driving circuit pins Pin1, IC Pin 2, and IC Pin3 simultaneously send the touch driving signal VT; after that, the data lines and data are driven. Circuit The touch sensing signal VR is received by the pins Pin1, IC Pin 2, and IC Pin3.
第二種是控制信號線M1、M2、M3中的至少一者開啟開關，剩餘的控制信號線關閉開關，且每個腳位IC Pin1、IC Pin 2、IC Pin3同時送出觸控驅動信號VT。藉此，使得每一組的特定的資料線輸出觸控驅動信號VT。例如，控制信號線M1將各組的開關SW4開啟，控制信號線M2及M3將各組的開關SW5、SW6關閉，每個腳位IC Pin1、IC Pin 2、IC Pin3同時送出觸控驅動信號VT。這樣一來，可讓資料線24-1、24-4、24-7同時送出觸驅動測信號VT；之後，再由資料線，經由Pin1、IC Pin 2、IC Pin3，資料驅動電路接收觸控感測訊號VR回傳至。 The second type is that at least one of the control signal lines M1, M2, and M3 turns on the switch, and the remaining control signal lines turn off the switch, and each of the pin ICs Pin1, IC Pin 2, and IC Pin3 simultaneously sends out the touch driving signal VT. Thereby, the specific data lines of each group are outputted to the touch driving signal VT. For example, the control signal line M1 turns on the switches SW4 of each group, and the control signal lines M2 and M3 turn off the switches SW5 and SW6 of each group, and each pin IC Pin1, IC Pin 2, and IC Pin3 simultaneously send the touch driving signal VT. . In this way, the data lines 24-1, 24-4, and 24-7 can simultaneously send out the touch drive measurement signal VT; after that, the data line receives the touch through the Pin1, IC Pin 2, IC Pin3, and the data drive circuit. The sensing signal VR is transmitted back to.
第三種是控制信號線M1、M2、M3同時將全部的開關開啟，由資料驅動電路的腳位IC Pin1、IC Pin 2、IC Pin3來決定何時要出輸出觸控驅動資料VT給哪一組的資料線；之後，再由資料線，經由所選擇的腳位Pin，資料驅動電路接收觸控感測訊號VR。 The third type is that the control signal lines M1, M2, and M3 turn on all the switches at the same time, and the pin IC1, IC Pin 2, and IC Pin3 of the data driving circuit determine when to output the touch driving data VT to which group. After the data line, the data driving circuit receives the touch sensing signal VR via the selected pin pin.
根據上述的各個實施例，本發明提出了內嵌式觸控顯示面板及其觸控模式的驅動方法，可減少觸控感測電極與其他線路之間的耦合電容，並同時可滿足觸控功能及指紋辨識功能，且不需額外的走線，來傳遞共同電極、觸控驅動信號及觸控感測信號。 According to the foregoing embodiments, the present invention provides an in-cell touch display panel and a driving method thereof, which can reduce the coupling capacitance between the touch sensing electrodes and other lines, and simultaneously satisfy the touch function. And the fingerprint identification function, and no additional wiring is required to transmit the common electrode, the touch driving signal and the touch sensing signal.
雖本發明以上述實施例來說明，但並不限於此。更進一步地說，在熟習該領域技藝人士不脫離本發明的概念與同等範疇之下，申請專利範圍必須廣泛地解釋以包括本發明實施例及其他變形。 Although the invention has been described in the above embodiments, it is not limited thereto.
