Description
本說明書主要係有關於內嵌式觸控顯示面板之技術，特別係有關於用以改善畫面色斑(mura)或是改善觸控效能(touch performance)變差之內嵌式觸控顯示面板技術。 This manual is mainly about the technology of the in-cell touch display panel, especially the in-cell touch display panel technology for improving the mura or improving the touch performance. .
內嵌式觸控顯示面板(In-Cell Touch Display)是同時將顯示功能與觸控功能整合於面板內之的新式整合型顯示器。這種新式面板是藉由將面板IC與觸控IC的整合，並搭配液晶面板廠的新式製作流程，所開發出的新式液晶面板之一。 In-Cell Touch Display is a new integrated display that integrates display and touch functions into the panel at the same time. This new panel is one of the new LCD panels developed by integrating the panel IC with the touch IC and matching the new production process of the LCD panel factory.
內嵌觸控顯示面板，若以觸控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，發出觸控信號與接收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信號與接收感測信號的路徑相同。有一種習知的自容式內嵌觸控顯示面板，係將共用電極(或稱接地電極)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仍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 embedded touch display panel can be divided into mutual capacitance type and self-capacity type according to the way of transmitting the touch signal. In the in-line touch display panel, the path of the touch signal is different from the path of receiving the sensing signal. The self-contained in-cell touch display panel emits the same touch signal as the path for receiving the sensing signal. There is a conventional self-capacitive in-cell touch display panel, which divides a common electrode (or a ground electrode) into a plurality of electrode blocks arranged in a matrix, each An electrode block is still used as a common common electrode during display, and is used as a touch sensing electrode during touch control, and is determined by detecting a capacitance formed between the electrode block and an external touch object. The position of the touch object.
第1圖係顯示一種習知的內嵌觸控顯示面板的部分概要上視圖。如第1圖所示，每一塊矩陣共用電極塊S1、S2、...、Sn會利用多個接觸孔C分別連接到一條金屬導線T1、T2、...、Tn。在內嵌觸控顯示面板的顯示驅動期間，這些金屬導線T1、T2、...、Tn會輸出一既定的電壓，使所有的共用電極塊S1、S2、...、Sn維持在相同的電位；在內嵌觸控顯示面板的觸控驅動期間，這些金屬導線T1、T2、...、Tn會各自輸出觸控感測信號，用以獨立地感測各個共用電極塊S1、S2、...、Sn是否被觸控。 Figure 1 is a partial top plan view showing a conventional in-cell touch display panel. As shown in Fig. 1, each of the matrix common electrode blocks S1, S2, ..., Sn is connected to a single metal wire T1, T2, ..., Tn by a plurality of contact holes C, respectively. During the display driving of the in-cell touch display panel, the metal wires T1, T2, ..., Tn output a predetermined voltage, so that all the common electrode blocks S1, S2, ..., Sn are maintained at the same level. During the touch driving of the in-cell touch display panel, the metal wires T1, T2, ..., Tn each output a touch sensing signal for independently sensing the respective common electrode blocks S1, S2. ..., is Sn touched?
在傳統內嵌觸控顯示面板之製作中，為避免觸控訊號(Sensing Signal)與薄膜電晶體(Thin Film Transistor，TFT)元件和資料訊號(Data Signal)互相干擾，會於觸控面板的結構中，設計一金屬層(例如：一M3層)，經由接觸孔(contact hole)傳遞觸控訊號至共用電極塊。底下將以第2圖舉例說明。 In the production of the conventional in-cell touch display panel, in order to avoid interference between the Sensing Signal and the Thin Film Transistor (TFT) component and the Data Signal, the structure of the touch panel is A metal layer (for example, an M3 layer) is designed to transmit a touch signal to the common electrode block via a contact hole. The figure below will be illustrated by the second figure.
第2圖係顯示一種習知的經由共用電極在畫素電極上方(top com)之製程方式製作之觸控顯示面板之剖面圖。如第2圖所示，先沉積閘極電極金屬(gate electrode，GE)層210(可視為M1層)並圖形化，沈積閘極絕緣層(gate insulation(GI)layer)220與主動層(Active layer)230(或半導體層(semiconductor layer))，且圖形化主動層230和閘極絕緣層220，並在閘極絕緣層220挖接觸孔至閘極電極金屬層210。 接著，沉積源極和汲極金屬層(Source/Drain(SD)metal layer)240(可視為M2層)，並圖形化源極和汲極金屬層240，且部份源極和汲極金屬層240會與閘極電極金屬210做連接(M1、M2轉接)。接著，在沈積第一保護層(passivation layer(BP1))250與平坦層(PFA)260後，圖形化第一保護層250和平坦層260，以挖接觸孔至源極和汲極金屬層240。此外，亦會沈積畫素電極層(ITO_pixel layer)270，並圖形化畫素電極層270，作為觸控顯示面板之畫素電極並使其透過接觸孔連接底層之源極和汲極金屬層240之薄膜電晶體汲極(TFT drain)端，其中ITO係表示銦錫氧化物(Indium Tin Oxide，ITO)。接著，沈積第二保護層(BP2)280，以及沈積一金屬層(M3 layer)290(觸控信號線(touch line)之金屬導線)，並圖形化M3層290使其覆蓋於源極和汲極金屬層240之資料線(data line)上。接著，沈積第三保護層(BP3)295，並圖形化第三保護層295，以挖接觸孔於M3層上。最後，沈積共用電極層(ITO_Com layer)271，並圖形化共用電極層271使其形成ITO切口(slit)以作為顯示器共用電極，並透過其下層之第三保護層295之接觸孔連接底層之M3層290。 Figure 2 is a cross-sectional view showing a conventional touch display panel fabricated by a common electrode in a top com process. As shown in Fig. 2, a gate electrode (GE) layer 210 (which can be regarded as an M1 layer) is first deposited and patterned, and a gate insulation (GI) layer 220 and an active layer are deposited. A layer 230 (or a semiconductor layer), and patterned the active layer 230 and the gate insulating layer 220, and digs a contact hole in the gate insulating layer 220 to the gate electrode metal layer 210. Next, a source/Drain (SD) metal layer 240 (which can be regarded as an M2 layer) is deposited, and the source and drain metal layers 240 are patterned, and some of the source and drain metal layers are patterned. 240 will be connected to the gate electrode metal 210 (M1, M2 transfer). Next, after depositing the first passivation layer (BP1) 250 and the flat layer (PFA) 260, the first protective layer 250 and the flat layer 260 are patterned to dig the contact holes to the source and drain metal layers 240. . In addition, an ITO_pixel layer 270 is deposited, and the pixel electrode layer 270 is patterned as a pixel electrode of the touch display panel and connected to the source and the drain metal layer 240 of the bottom layer through the contact hole. The thin film transistor drain terminal (TFT drain), wherein the ITO system represents Indium Tin Oxide (ITO). Next, a second protective layer (BP2) 280 is deposited, and a metal layer (M3 layer) 290 (a metal line of a touch line) is deposited, and the M3 layer 290 is patterned to cover the source and the drain. On the data line of the polar metal layer 240. Next, a third protective layer (BP3) 295 is deposited, and a third protective layer 295 is patterned to dig the contact holes on the M3 layer. Finally, a common electrode layer (ITO_Com layer) 271 is deposited, and the common electrode layer 271 is patterned to form an ITO slit as a display common electrode, and is connected to the underlying M3 through a contact hole of the lower third protective layer 295. Layer 290.
第3圖係顯示一種習知的內嵌觸控顯示面板的金屬導線布局之示意圖。如第3圖所示，排列成矩陣狀的共用電極塊配置於基板10的顯示區域11上，而用以共用電位及觸控感測信號的驅動晶片則配置於顯示區域11外的非顯示區域12。金屬導線在顯示區域11內均平行於行方向延伸，出了顯示區域11後在非顯示區域12以扇形的方式連接進驅動晶 片。在傳統的布局下，連接至同一行的共用電極塊的金屬導線中，位於最左側的金屬導線Tmax連接到顯示區域11內最上方的共用電極塊，因此在顯示區域11內有最長的長度，同時該條金屬導線在非顯示區域12由於距離驅動晶片較遠，因此在非顯示區域12也有最長的長度。相對地，連接至同一行的共用電極塊的金屬導線中，位於最右側的金屬導線Tmin連接到顯示區域11內最下方的共用電極塊，因此在顯示區域11內有最短的長度，同時該條金屬導線在非顯示區域12由於距離驅動晶片較近，因此在非顯示區域12也有最短的長度。 Figure 3 is a schematic diagram showing the layout of a metal wire of a conventional in-cell touch display panel. As shown in FIG. 3, the common electrode blocks arranged in a matrix are disposed on the display area 11 of the substrate 10, and the driving chips for sharing the potential and the touch sensing signals are disposed in the non-display area outside the display area 11. 12. The metal wires extend parallel to the row direction in the display region 11, and after the display region 11 is exited, the drive crystals are connected in a fan shape in the non-display region 12. sheet. In the conventional layout, among the metal wires connected to the common electrode block of the same row, the metal wire Tmax located at the leftmost side is connected to the uppermost common electrode block in the display region 11, and thus has the longest length in the display region 11, At the same time, the metal wire has a longest length in the non-display area 12 due to the distance from the drive wafer in the non-display area 12. In contrast, among the metal wires connected to the common electrode block of the same row, the metal wire Tmin located at the rightmost side is connected to the lowermost common electrode block in the display region 11, and thus has the shortest length in the display region 11, and the strip The metal wire is also in the non-display area 12 due to its proximity to the drive wafer, and therefore has the shortest length in the non-display area 12.
因此，因為在靠近驅動晶片及遠離驅動晶片之位置之金屬導線(M3走線)長度不一樣，所以會導致RC負載不均之問題產生。若RC負載不均之問題產生。當RC負載之差異過大時，將導致觸控顯示面板畫面容易產生色斑(mura)或是觸控效能(touch performance)變差之情況發生。 Therefore, since the length of the metal wires (M3 traces) at a position close to the drive wafer and away from the drive wafer is different, a problem of uneven RC load may occur. If the RC load is uneven, the problem arises. When the difference in RC load is too large, the touch display panel screen is likely to cause mura or touch performance to deteriorate.
