Description

觸控顯示面板 Touch display panel

本發明係有關於一種觸控顯示面板，且特別有關於能夠改善畫面色斑(mura)的觸控顯示面板。 The present invention relates to a touch display panel, and more particularly to a touch display panel capable of improving picture mura.

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。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。 The touch-in display (TID) is a new integrated display with both display and touch functions. 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.

有一種內嵌觸控顯示面板，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。 There is an in-cell touch display panel, which divides a common electrode (or a ground electrode) into a plurality of electrode blocks arranged in a matrix, and each electrode block is still used as a common common electrode during display, and is in touch. During the period, it is used as a touch sensing electrode, and the position of the touch object is determined by detecting the capacitance formed between the electrode block and the external 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S1、S2、...、Sn是否被觸控。而金屬導線T1、T2、...、Tn所送出的觸控感測信號如第2圖所示，所有的觸控感測信號的時序與振幅均相同。當觸控感測信號傳遞到各共用電極S1、S2、...、Sn後，透過比較觸碰造成之電容、電荷、訊號、充電時間等至少一者差異，來判定碰觸的位置。 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 electrodes 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 to maintain all the common electrodes S1, S2, ..., Sn at the same potential. During the touch driving of the embedded touch display panel, the metal wires T1, T2, ..., Tn each output a touch sensing signal for independent sensing. Whether each of the common electrodes S1, S2, ..., Sn is touched. As shown in FIG. 2, the touch sensing signals sent by the metal wires T1, T2, ..., Tn have the same timing and amplitude of all the touch sensing signals. After the touch sensing signal is transmitted to each of the common electrodes S1, S2, ..., Sn, the position of the touch is determined by comparing at least one difference in capacitance, electric charge, signal, charging time, and the like caused by the touch.

而上述顯示驅動期間與觸控驅動期間會輪流交替，使內嵌觸控顯示面板完成顯示與觸控的功能。第3圖係顯示某一共用電極在顯示驅動期間及觸控驅動時間的電位波形圖。一共用電極在顯示驅動期間PD會維持於一特定的共用電位Vcom，在觸控驅動期間PT則會被驅動到一觸控高電位Vtouch。需注意的是上述觸控高電位Vtouch可視為例如第2圖所示的多個高低位準的脈衝的平均電位，在此，為了聚焦於觸控驅動期間PT與顯示驅動期間PD的交界處的電位變化，而不畫出共用電極在觸控驅動期間PT時相對上較小的電位變化。 The display driving period and the touch driving period alternately alternately, so that the embedded touch display panel performs the functions of display and touch. Fig. 3 is a diagram showing potential waveforms of a certain common electrode during display driving and touch driving time. A common electrode display driving period P D will be maintained at a particular common potential Vcom, during the touch driving P T will be driven to a high potential touch Vtouch. It should be noted that the above-mentioned touch high potential Vtouch can be regarded as, for example, the average potential of a plurality of high and low level pulses shown in FIG. 2, in order to focus on the boundary between the touch driving period P T and the display driving period P D . The potential change at the location does not show a relatively small potential change of the common electrode during the touch drive period P T .

然而，習知技術的金屬導線的布局方式因左右相鄰的共用金屬塊的接觸孔與共用金屬塊的邊緣的距離不同，使得信號傳遞到共用金屬塊的邊緣的阻抗產生差異。 However, the metal wire of the prior art is arranged in such a manner that the distance between the contact hole of the adjacent metal block and the edge of the common metal block is different, so that the impedance of the signal transmitted to the edge of the common metal block is different.

第4A圖係顯示第1圖中由虛線框起來的兩個相鄰的共用電極的放大。如第4A圖中所示，電流都是按照箭頭方向由下往上流到共用電極S2、Sm中，並且在到達接觸控後分別往兩側的邊緣流動。在共用電極S2中，電流從接觸孔C流到右側邊緣E1的距離為L1；在共用電極Sm中，電流從接觸孔C流到左側邊緣E2的距離為L2，而距離L1較距離L2長。 Figure 4A shows an enlargement of two adjacent common electrodes framed by dashed lines in Figure 1. As shown in Fig. 4A, the current flows from bottom to top in the direction of the arrow to the common electrodes S2, Sm, and flows to the edges on both sides after reaching the contact control. In the common electrode S2, the distance from the contact hole C to the right edge E1 is L1; in the common electrode Sm, the distance from the contact hole C to the left edge E2 is L2, and the distance L1 is longer than the distance L2.

第4B及第4C圖係分別顯示相鄰的共用電極的邊緣在 顯示驅動期間及觸控驅動時間的電位波形圖。第4B圖表示第4A圖中的左側邊緣E2的位置的信號波形，第4C圖表示第4A圖中的右側邊緣E1的位置的信號波形。由於信號到達共用電極Sm的左側邊緣E2的距離較短，因此阻抗較小，當信號從觸控驅動期間PT進入顯示驅動期間PD時，電位能夠較快地到達共用電位Vcom，信號失真的程度較小。然而，由於信號到達共用電極S2的右側邊緣E1的距離較長，因此阻抗較大，當信號從觸控驅動期間PT進入顯示驅動期間PD時，電位能夠較慢地到達共用電位Vcom，信號失真的程度較大。如此一來會造成相鄰的共用電極交界處的共用電位Vcom的失真程度不一致，使得交界處產生畫面色斑的現象。 4B and 4C are diagrams showing potential waveforms of the edges of adjacent common electrodes during the display driving period and the touch driving time. Fig. 4B shows a signal waveform of the position of the left edge E2 in Fig. 4A, and Fig. 4C shows a signal waveform of the position of the right edge E1 in Fig. 4A. Since the distance from the signal to the left edge E2 of the common electrode Sm is short, the impedance is small. When the signal enters the display driving period P D from the touch driving period P T , the potential can reach the common potential Vcom relatively quickly, and the signal is distorted. To a lesser extent. However, since the signal reaches a long distance from the right edge E1 of the common electrode S2, the impedance is large. When the signal enters the display driving period P D from the touch driving period P T , the potential can reach the common potential Vcom slowly, the signal The degree of distortion is greater. As a result, the degree of distortion of the common potential Vcom at the junction of the adjacent common electrodes is inconsistent, causing a phenomenon of screen color on the boundary.

另一方面，排列成矩陣狀的共用電極配置於基板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IC則配置於顯示區域11外的非顯示區域12。傳統的金屬導線的布局方式如第5A、5B圖所示。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IC。在傳統的布局下，連接至同一行的共用電極的金屬導線中，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，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IC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，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IC較近，因此在非顯示區域12也有最短的長度。 On the other hand, the common electrodes arranged in a matrix are disposed on the display region 11 of the substrate 10, and the driving chip IC for sharing the potential and the touch sensing signal is disposed in the non-display region 12 outside the display region 11. The layout of the conventional metal wires is as shown in Figs. 5A and 5B. The metal wires extend parallel to the row direction in the display region 11, and after the display region 11 is exited, the drive wafer IC is connected in a fan shape in the non-display region 12. In the conventional layout, among the metal wires connected to the common electrode of the same row, the metal wire Tmax located at the leftmost side is connected to the uppermost common electrode in the display region 11, and thus has the longest length in the display region 11, and The strip metal wires are farther in the non-display area 12 due to the distance driving the chip IC, and therefore have the longest length in the non-display area 12. In contrast, among the metal wires connected to the common electrode of the same row, the metal wire Tmin located at the rightmost side is connected to the lowermost common electrode in the display region 11, and thus has the shortest length in the display region 11, and the metal wire In the non-display area 12, since it is closer to the driving chip IC, it also has the shortest length in the non-display area 12.

這樣一來，最長的金屬導線Tmax的RC負載遠比最短的金屬導線Tmin的RC負載大。然而，在設計上不同的金屬導線仍需要在符合同一RC負載的規格，因此傳統的金屬導線的布局方式會增加設計上的困難度。 In this way, the RC load of the longest metal wire Tmax is much larger than the RC load of the shortest metal wire Tmin.

以下根據圖式說明本發明的觸控顯示面板。在不同的圖式及對應的說明中標示相同的符號表示相同的元件而省略重複說明。 The touch display panel of the present invention will be described below based on the drawings. The same reference numerals are given to the same elements in the different drawings and the corresponding description, and the repeated description is omitted.

第6A圖係顯示本發明實施例1的內嵌觸控顯示面板的金屬導線布局的示意圖。第6B-1、6B-2圖係顯示第6A圖中由虛線框起來的部位的放大圖。在實施例1中，從基板左側往右側(或右側往左側)觀看，顯示區域11內的金屬導線依序由最短逐漸到最長，再由最長逐漸到最短，如此反覆交替於長度變長與長度變 短的分佈。在這樣的布局下，可以使得在列方向上相鄰的兩個共用電極中的接觸孔到兩者的交界之間的距離相等。在此實施例中列方向相當於申請專利範圍中的第一方向，行方向相當於申請專利範圍中的第二方向。 FIG. 6A is a schematic view showing the layout of the metal wires of the in-cell touch display panel according to Embodiment 1 of the present invention. Fig. 6B-1, 6B-2 show an enlarged view of a portion framed by a broken line in Fig. 6A. In the first embodiment, viewed from the left side of the substrate to the right side (or the right side to the left side), the metal wires in the display area 11 are gradually changed from the shortest to the longest, and then from the longest to the shortest, so that the length is longer and longer. change Short distribution. Under such a layout, the distance between the contact holes in the two common electrodes adjacent in the column direction to the boundary between the two can be made equal. In this embodiment, the column direction corresponds to the first direction in the patent application range, and the row direction corresponds to the second direction in the patent application range.

具體來說，如第6B-1圖所示，以最上方的相鄰的三塊共用電極為例，這三塊共用電極由左到右分別為Sa、Sb、Sc。共用電極Sa的邊緣E1(相當於申請專利範圍中的第一側邊)與共用電極Sb的邊緣E2(相當於申請專利範圍中的第二側邊)相鄰，共用電極Sb的邊緣E1與共用電極Sc的邊緣E2相鄰。共用電極Sa的接觸孔至邊緣E1的最短距離a會等於共用電極Sb的接觸孔至邊緣E2的最短距離b，而共用電極Sb的接觸孔至邊緣E1的最短距離c會等於共用電極Sc的接觸孔至邊緣E2的最短距離d。同樣地，如第6B-2圖所示。以最下方的相鄰的三塊共用電極為例，這三塊共用電極由左到右分別為Sd、Se、Sf。共用電極Sd的邊緣E1與共用電極Se的邊緣E2相鄰，共用電極Se的邊緣E1與共用電極Sf的邊緣E2相鄰。共用電極Sd的接觸孔至邊緣E1的最短距離e會等於共用電極Se的接觸孔至邊緣E2的最短距離f，而共用電極Se的接觸孔至邊緣E1的最短距離g會等於共用電極Sf的接觸孔至邊緣E2的最短距離h。 Specifically, as shown in FIG. 6B-1, taking the three adjacent common electrodes in the uppermost position as an example, the three common electrodes are Sa, Sb, and Sc from left to right. The edge E1 of the common electrode Sa (corresponding to the first side in the patent application) is adjacent to the edge E2 of the common electrode Sb (corresponding to the second side in the patent application), and the edge E1 of the common electrode Sb is shared. The edge E2 of the electrode Sc is adjacent. The shortest distance a of the contact hole of the common electrode Sa to the edge E1 is equal to the shortest distance b of the contact hole of the common electrode Sb to the edge E2, and the shortest distance c of the contact hole of the common electrode Sb to the edge E1 is equal to the contact of the common electrode Sc. The shortest distance d from the hole to the edge E2. Similarly, as shown in Figure 6B-2. Taking the three adjacent common electrodes at the bottom as an example, the three common electrodes are Sd, Se, and Sf from left to right. The edge E1 of the common electrode Sd is adjacent to the edge E2 of the common electrode Se, and the edge E1 of the common electrode Se is adjacent to the edge E2 of the common electrode Sf. The shortest distance e of the contact hole of the common electrode Sd to the edge E1 is equal to the shortest distance f of the contact hole of the common electrode Se to the edge E2, and the shortest distance g of the contact hole of the common electrode Se to the edge E1 is equal to the contact of the common electrode Sf. The shortest distance h from the hole to the edge E2.

這樣一來，對於列方向上任二個相鄰的共用電極來說，由於接觸孔到兩共用電極的相鄰的邊緣之間的距離相等，因此就可以減低信號透過金屬導線到達邊界的阻抗差異，而降低畫面色斑的狀況。另外，由於位於非顯示區域12中最長的金屬導線連接到顯示區域11中最短的金屬導線，所以可以降低金屬導線過 長所造成的RC負載，使金屬導線較容易符合的RC負載的規格。 In this way, for any two adjacent common electrodes in the column direction, since the distance between the contact holes and the adjacent edges of the two common electrodes is equal, the impedance difference between the signal and the metal wire reaching the boundary can be reduced. And reduce the condition of the picture stain. In addition, since the longest metal wire located in the non-display area 12 is connected to the shortest metal wire in the display area 11, the metal wire can be lowered. The long resulting RC load makes the metal wire easier to conform to the RC load specification.

第7A圖係顯示本發明實施例2的內嵌觸控顯示面板的金屬導線布局的示意圖。第7B圖係顯示第7A圖中由虛線框起來的部位的放大圖。在實施例2中，最大的特徵在連接至同一行的共用電極的複數條金屬導線會往共用電極的中央集中。這樣一來，可以減低金屬導線至共用電極的邊緣的最長的距離與金屬導線至共用電極的兩側邊緣的距離差異。在實施例1中，如第6B-1圖所示，以共用電極Sb為例，金屬導線至邊緣E1的距離為c，至邊緣E2的距離是b。距離c與距離b恰好是所有金屬導線至共用電極邊緣的最長距離與最短距離，兩者之間的差異大，因此即使是同一共用電極的兩側邊緣也有阻抗差異的問題。然而，在實施例2中，將金屬導線往共用電極的中央集中，可以減少金屬導線至左側邊緣與右側邊緣之間的距離差異，以降低阻抗差。 FIG. 7A is a schematic view showing the layout of the metal wires of the in-cell touch display panel according to Embodiment 2 of the present invention. Fig. 7B is an enlarged view showing a portion framed by a broken line in Fig. 7A. In Embodiment 2, the largest feature is that a plurality of metal wires connected to the common electrode of the same row are concentrated toward the center of the common electrode. In this way, the difference between the longest distance of the metal wire to the edge of the common electrode and the distance of the metal wire to the both side edges of the common electrode can be reduced. In the first embodiment, as shown in FIG. 6B-1, taking the common electrode Sb as an example, the distance from the metal wire to the edge E1 is c, and the distance from the edge E2 is b. The distance c and the distance b are the longest distance and the shortest distance from all the metal wires to the edge of the common electrode, and the difference between the two is large, so that even the edges of the same common electrode have a problem of impedance difference. However, in Embodiment 2, the metal wires are concentrated toward the center of the common electrode, and the difference in distance between the metal wires to the left edge and the right edge can be reduced to reduce the impedance difference.

而複數條金屬導線會往共用電極的中央集中的態樣，具體來說可用第7A圖中最下方的一塊共用電極Sd為例來說明。如第7B圖所示，共用電極Sd的範圍內有連接至該行的共用電極的全部的N條金屬導線通過，此時假設最靠左側的金屬導線至左側的邊緣的距離為La，最靠右側的金屬導線至右側的邊緣的距離為Lb，而最靠左側的金屬導線至最靠右側的金屬導線之間的距離為Lc，相鄰的金屬導線之間的距離由左到右分別為l1、l2、...、lN-2、lN-1。 The plurality of metal wires are concentrated toward the center of the common electrode. Specifically, the lower common electrode Sd in FIG. 7A can be used as an example. As shown in FIG. 7B, all of the N metal wires connected to the common electrode of the row pass through the range of the common electrode Sd, and it is assumed that the distance from the leftmost metal wire to the left edge is La, the most The distance from the metal wire on the right side to the edge on the right side is Lb, and the distance between the metal wire on the far side to the rightmost metal wire is Lc, and the distance between adjacent metal wires is from left to right. 1 , l 2 , ..., l N-2 , l N-1 .

在一個實施態樣中，複數條金屬導線會往共用電極的中央集中必須滿足任兩條相鄰的金屬導線之間的距離小於最靠左側的金屬導線至左側的邊緣的距離，並且，小於最靠右側的金 屬導線至右側的邊緣的距離。也就是，l1、l2、...、lN-2、lN-1<La且l1、l2、...、lN-2、lN-1<Lb。在另一態樣中，複數條金屬導線會往共用電極的中央集中必須進一步滿足任兩條相鄰的金屬導線之間的距離小於最靠左側的金屬導線至左側的邊緣的距離的1/2，並且，小於最靠右側的金屬導線至右側的邊緣的距離的1/2。也就是，l1、l2、...、lN-2、lN-1<(1/2)La且l1、l2、...、lN-2、lN-1<(1/2)Lb。另外，在另一態樣中，也可以是任兩條相鄰的金屬導線之間的平均距離小於最靠左側的金屬導線至左側的邊緣的距離，並且，小於最靠右側的金屬導線至右側的邊緣的距離。而任兩條相鄰的金屬導線之間的平均距離為全部金屬導線橫跨的距離除以相鄰的金屬導線的間距數目。因此，滿足的條件相當於Lc/(N-1)<La且Lc/(N-1)<Lb。符合上述三種實施態樣中的任一者即可視為達成複數條金屬導線往共用電極的中央集中的具體實施例。 In one embodiment, the plurality of metal wires will be concentrated toward the center of the common electrode, and the distance between any two adjacent metal wires must be less than the distance from the leftmost metal wire to the left edge, and less than the most The distance from the metal wire on the right to the edge on the right. That is, l 1 , l 2 , ..., l N-2 , l N-1 <La and l 1 , l 2 , ..., l N-2 , l N-1 <Lb. In another aspect, the concentration of the plurality of metal wires toward the center of the common electrode must further satisfy that the distance between any two adjacent metal wires is less than 1/2 of the distance from the leftmost metal wire to the left edge. And, less than 1/2 of the distance from the metal wire on the right side to the edge on the right side. That is, l 1 , l 2 , ..., l N-2 , l N-1 <(1/2)La and l 1 , l 2 , ..., l N-2 , l N-1 < (1/2) Lb. In addition, in another aspect, the average distance between any two adjacent metal wires may be smaller than the distance from the leftmost metal wire to the left edge, and less than the rightmost metal wire to the right side. The distance of the edge. The average distance between any two adjacent metal wires is the distance spanned by all metal wires divided by the number of pitches of adjacent metal wires. Therefore, the satisfied condition is equivalent to Lc/(N-1)<La and Lc/(N-1)<Lb. Any one of the above three embodiments can be considered as a specific embodiment for achieving a central concentration of a plurality of metal wires toward the common electrode.

第8圖係顯示本發明實施例3的內嵌觸控顯示面板的金屬導線布局的示意圖。在實施例3中，使用金屬導線在每一的共用電極內朝中央集中的特徵，但並不採取實施例1的金屬導線布局。也就是從基板左側往右側(或右側往左側)觀看，顯示區域11內的金屬導線並非反覆交替於長度逐漸變長與長度逐漸變短的分佈。列方向上相鄰的共用電極中，接觸孔到兩共用電極的相鄰的邊緣之間的距離並不相等。然而，由於全部的金屬導線已朝向共用電極的中央集中，因此在某種程度上仍然能夠減低金屬導線到共用電極的邊緣的差異所帶來的影響。 Figure 8 is a schematic view showing the layout of a metal wire of the in-cell touch display panel of Embodiment 3 of the present invention. In Embodiment 3, the feature that the metal wires are concentrated toward the center in each of the common electrodes is used, but the metal wire layout of Embodiment 1 is not taken. That is, from the left side of the substrate to the right side (or the right side to the left side), the metal wires in the display area 11 are not alternately alternated with a distribution in which the length gradually becomes longer and the length becomes shorter. In the common electrodes adjacent in the column direction, the distance between the contact holes and the adjacent edges of the two common electrodes is not equal. However, since all the metal wires have been concentrated toward the center of the common electrode, the influence of the difference in the edge of the metal wires to the common electrode can still be reduced to some extent.

第9圖係顯示本發明實施例4的內嵌觸控顯示面板的金屬導線布局的示意圖。在上述實施例1-3中，均採取金屬導線在 顯示區域11內平行於行方向延伸的布局方式，然而，如第9圖所示，金屬導線在顯示區域11內可以平行於列方向延伸。此時，可將顯示區域11分成左右兩個部分，左側的顯示區域11內的共用電極所連接的金屬導線平行於列方向朝左側延伸出顯示區域11外，然後在非顯示區域12內沿著顯示區域11的邊緣延伸連接到驅動晶片IC為止；同樣地，右側的顯示區域11內的共用電極所連接的金屬導線平行於列方向朝右側延伸出顯示區域11外，然後在非顯示區域12內沿著顯示區域11的邊緣延伸連接到驅動晶片IC為止。而實施例4除了金屬導線在顯示區域11內平行於列方向上外，布局的特徵與實施例1相同。從基板上側往下側(或下側往上側)觀看，顯示區域11內的金屬導線依序由最短逐漸到最長，再由最長逐漸到最短，反覆交替於長度變長與長度變短的分佈。在這樣的布局下，可以使得在行方向上相鄰的兩個共用電極中的接觸孔到兩者的交界之間的距離相等。在此實施例中行方向相當於申請專利範圍中的第一方向，列方向相當於申請專利範圍中的第二方向，而平行於列方向的共用電極的邊緣相當於第一邊緣及第二邊緣。 FIG. 9 is a schematic view showing a layout of a metal wire of an in-cell touch display panel according to Embodiment 4 of the present invention. In the above embodiments 1-3, both take metal wires at The layout of the display region 11 extending parallel to the row direction, however, as shown in Fig. 9, the metal wires may extend parallel to the column direction in the display region 11. At this time, the display area 11 can be divided into two left and right portions, and the metal wires connected to the common electrodes in the display area 11 on the left side extend to the left side of the display area 11 in parallel with the column direction, and then along the non-display area 12 The edge of the display region 11 is extended to be connected to the driving wafer IC; likewise, the metal wires connected to the common electrode in the display region 11 on the right side extend out of the display region 11 toward the right side in parallel with the column direction, and then in the non-display region 12 Extending along the edge of the display area 11 is connected to the driving wafer IC. On the other hand, in the fourth embodiment, the features of the layout are the same as those in the first embodiment except that the metal wires are parallel to the column direction in the display region 11. Viewed from the upper side of the substrate to the lower side (or the lower side), the metal wires in the display area 11 are gradually changed from the shortest to the longest, and then from the longest to the shortest, and alternately the distribution in which the length becomes longer and the length becomes shorter. Under such a layout, the distance between the contact holes of the two common electrodes adjacent in the row direction to the boundary between the two can be made equal. In this embodiment, the row direction corresponds to the first direction in the patent application range, the column direction corresponds to the second direction in the patent application range, and the edge of the common electrode parallel to the column direction corresponds to the first edge and the second edge.

這樣一來，對於行方向上任二個相鄰的共用電極來說，由於接觸孔到兩共用電極的相鄰的邊緣之間的距離相等，因此就可以減低信號透過金屬導線到達邊界的阻抗差異，而降低畫面色斑的狀況。另外，由於位於非顯示區域12中最長的金屬導線連接到顯示區域11中最短的金屬導線，所以可以降低金屬導線過長所造成的RC負載，使金屬導線較容易符合的RC負載的規格。 In this way, for any two adjacent common electrodes in the row direction, since the distance between the contact holes and the adjacent edges of the two common electrodes is equal, the impedance difference between the signal and the metal wire reaching the boundary can be reduced. And reduce the condition of the picture stain. In addition, since the longest metal wire located in the non-display area 12 is connected to the shortest metal wire in the display area 11, the RC load caused by the excessive length of the metal wire can be reduced, making the metal wire easier to conform to the RC load specification.

第10圖係顯示本發明實施例5的內嵌觸控顯示面板的金屬導線布局的示意圖。如第10圖所示，金屬導線在顯示區域 11內平行於列方向延伸。然而，實施例5進一步採用在連接至同一列的共用電極的複數條金屬導線會往共用電極的中央集中的布局特徵。因此，實施例5相當於實施例2的變形，除了金屬導線在顯示區域11內平行於列方向上外，將金屬導線往共用電極的中央集中，可以減少金屬導線至上側邊緣與下側邊緣之間的距離差異，以降低阻抗差。 FIG. 10 is a schematic view showing a layout of a metal wire of an in-cell touch display panel according to Embodiment 5 of the present invention. As shown in Figure 10, the metal wire is in the display area. 11 extends parallel to the column direction. However, Embodiment 5 further employs a layout feature in which a plurality of metal wires connected to the common electrode of the same column are concentrated toward the center of the common electrode. Therefore, Embodiment 5 corresponds to the modification of Embodiment 2, except that the metal wires are concentrated in the display region 11 in parallel with the column direction, and the metal wires are concentrated toward the center of the common electrode, so that the metal wires can be reduced to the upper and lower edges. The difference in distance between them to reduce the impedance difference.

第11圖係顯示本發明實施例6的內嵌觸控顯示面板的金屬導線布局的示意圖。如第11圖所示，金屬導線在顯示區域11內平行於列方向延伸。實施例6與實施例5同樣使金屬導線在每一的共用電極內朝中央集中，但並不採取實施例4或5的金屬導線布局。也就是從基板上側往下側(或下側往上側)觀看，顯示區域11內的金屬導線並非反覆交替於長度逐漸變長與長度逐漸變短的分佈。行方向上相鄰的共用電極中，接觸孔到兩共用電極的相鄰的邊緣之間的距離並不相等。然而，由於全部的金屬導線已朝向共用電極的中央集中，因此在某種程度上仍然能夠減低金屬導線到共用電極的邊緣的差異所帶來的影響。 11 is a schematic view showing a layout of a metal wire of an in-cell touch display panel according to Embodiment 6 of the present invention. As shown in Fig. 11, the metal wires extend in the display region 11 in parallel with the column direction. In the same manner as in the embodiment 5, the metal wires were concentrated toward the center in each of the common electrodes, but the metal wire layout of the embodiment 4 or 5 was not employed. That is, from the upper side of the substrate to the lower side (or the lower side to the upper side), the metal wires in the display region 11 are not alternately arranged in a distribution in which the length gradually becomes longer and the length becomes shorter. In the common electrode adjacent in the row direction, the distance between the contact hole and the adjacent edges of the two common electrodes is not equal. However, since all the metal wires have been concentrated toward the center of the common electrode, the influence of the difference in the edge of the metal wires to the common electrode can still be reduced to some extent.

第12圖係顯示本發明實施例7的內嵌觸控顯示面板的金屬導線布局的示意圖。如第12圖所示，金屬導線在顯示區域11內平行於列方向延伸。實施例7與實施例6同樣使金屬導線在每一的共用電極內朝中央集中，但並不採取實施例4或5的金屬導線布局。與實施例6不同的是，實施例6中位於非顯示區域12中最長的金屬導線連接到顯示區域11中最短的金屬導線，所以可以降低金屬導線過長所造成的RC負載，使金屬導線較容易符合的RC負載的規格。 Figure 12 is a schematic view showing the layout of the metal wires of the in-cell touch display panel of Embodiment 7 of the present invention. As shown in Fig. 12, the metal wires extend in the display region 11 in parallel with the column direction. In the same manner as in the embodiment 6, the metal wires are concentrated toward the center in each of the common electrodes, but the metal wire layout of the embodiment 4 or 5 is not employed. The difference from Embodiment 6 is that the longest metal wire in the non-display area 12 of Embodiment 6 is connected to the shortest metal wire in the display area 11, so that the RC load caused by the excessive length of the metal wire can be reduced, and the metal wire can be made easier. Meet the specifications of the RC load.

綜上所述，根據上述實施例1至7的內嵌式觸控顯示面板的金屬導線布局，可以使相鄰的共用電極的接觸孔至兩者的交界的距離相等，藉此改善畫面色斑的現象。也可以使非顯示區域12外最長的金屬導線連接顯示區域11內最短的金屬導線，降低金屬導線的RC負載。再者，也可以將金屬導線集中於共用電極的中央，來降低同一共用電極中從接觸孔到兩側的邊緣的阻抗差異。 In summary, according to the metal wire layout of the in-cell touch display panel of the above embodiments 1 to 7, the distance between the contact holes of the adjacent common electrodes and the boundary of the two can be made equal, thereby improving the screen spot. The phenomenon. It is also possible to connect the longest metal wire outside the non-display area 12 to the shortest metal wire in the display area 11, and reduce the RC load of the metal wire. Furthermore, it is also possible to concentrate the metal wires in the center of the common electrode to reduce the impedance difference in the same common electrode from the contact hole to the edges on both sides.

另，本發明採用畫素電極與共用電極皆位於同一側基板的邊緣電場式(fringe field switching，FFS)電極架構，而這種架構包括頂部畫素電極式(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。 In addition, the present invention adopts a fringe field switching (FFS) electrode structure in which the pixel electrode and the common electrode are located on the same side substrate, and the structure includes a top pixel electrode (Top Pixel, the pixel electrode is adjacent to the top) 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).
