觸控面板由於具有人機互動與設計多樣化的特性，而被廣泛應用於儀器的外埠輸入介面。近年來隨著消費性電子產品應用面越來越廣，將觸控功能與顯示器結合而應用的產品也越來越多，例如行動電話(mobile phone)、衛星導航系統(GPS navigator system)、平板電腦(tablet PC)、以及筆記型電腦(laptop PC)等。 Touch panels are widely used in external input interfaces of instruments due to their characteristics of human-computer interaction and diverse design. In recent years, with the increasing application of consumer electronics products, more and more products are combined with touch functions and displays, such as mobile phones, GPS navigator systems, and tablets. Computer (tablet PC), and laptop (laptop PC).
而隨著科技之進步，人們對於電子產品品質要求越來越高，在激烈的競爭之下，電子製造商們紛紛以美觀、輕、薄、窄為目標，同時又希望其液晶螢幕能越大越好。一般來說，液晶螢幕四周的邊框區由於不具有顯示效果，且邊框區的存在也影響到視覺上的美觀效果，因此，電子製造商們皆致力於研發邊框微縮技術。 With the advancement of technology, people have higher and higher requirements for the quality of electronic products. Under the fierce competition, electronics manufacturers have aimed at beautiful, light, thin, and narrow, and they hope that the larger the LCD screen, it is good. Generally speaking, the border area around the LCD screen does not have a display effect, and the presence of the border area also affects the visual aesthetic effect. Therefore, electronics manufacturers are committed to developing the frame shrink technology.
請參閱圖1所示，其為目前常見的觸控結構示意圖。一般的觸控結構通常包括一可視區以及一邊框油墨區，該可視區包括兩個觸控電極(Rx,Tx)，邊框油墨區用以設置兩個觸控電極的電路走線4a、5a。為了達到窄邊框的效果，目前多是採用電路走線微縮技術，然而，邊框區的最小化有其實踐上之限制，目前電路走線微縮已達到10/10水準，若再追求線路 微縮則需要付出高額的製造成本，不符合經濟效益。此外，亦有廠商提出將感測電極邊緣反折的技術，然而此技術目前仍有反折區域受本身應力造成貼合不良、反折時公差等問題，故仍有待改進。 Please refer to FIG. 1, which is a schematic diagram of a common touch structure. A general touch structure generally includes a visible area and a frame ink area. The visible area includes two touch electrodes (Rx, Tx). The frame ink area is used to set the circuit traces 4a, 5a of the two touch electrodes. In order to achieve the effect of narrow bezels, circuit routing miniaturization technology is currently used. However, the minimization of the frame area has its practical limitations. At present, the circuit trace miniaturization has reached 10/10 level. Miniaturization requires high manufacturing costs, which is not economical. In addition, some manufacturers have proposed the technology of rebending the edge of the sensing electrode. However, this technology still has problems such as poor fit and tolerance during rebend due to its own stress in the rebend area, so it still needs to be improved.

The third sensing electrode is composed of a plurality of sensing blocks, and a gap is formed between two adjacent sensing blocks.
第三電極區23的感應電極具有分段式結構，將同一個感應電極區分為複數個區塊，且該等區塊透過該第二緩衝區走線43電訊連接。任一條該第二緩衝區走線43僅與一個第三電極區23的感應電極電性連接，該第二緩衝區走線43大致沿著該第二方向92設置，與第三電極區23的感應電極排列方向互相垂直，以利將感測訊號傳遞至該接腳區74。 The sensing electrodes of the third electrode region 23 have a segmented structure, and the same sensing electrode is divided into a plurality of blocks, and the blocks are connected by telecommunications through the second buffer line 43. Any one of the second buffer traces 43 is electrically connected to a sensing electrode of a third electrode region 23. The second buffer traces 43 are disposed substantially along the second direction 92 and are connected to the third electrode region 23. The arrangement directions of the sensing electrodes are perpendicular to each other, so that the sensing signals are transmitted to the pin area 74.
該第二緩衝區走線43與該等感應區塊電訊連接，並透過該間隙將觸控訊號導出至該接腳區74。其中，在任意兩條第二緩衝區走線43的交叉處設置有一絕緣層81，使第三電極區23的感應電極各自電性獨立不互相干擾。以本較佳實施例來說，圖4中所示出的第三電極區23的感應電極結構包括一個未分段的感應電極231、一個分為兩個區塊的感應電極232以及一個分為四個區塊的感應電極233，未分段的感應電極231透過走線431傳遞訊號，分為兩個區塊的感應電極232透過走線432傳遞訊號，而分為四個區塊的感應電極233透過走線433傳遞訊號。 The second buffer line 43 is electrically connected to the sensing blocks, and the touch signal is exported to the pin area 74 through the gap. Wherein, an insulating layer 81 is provided at the intersection of any two of the second buffer line 43 so that the sensing electrodes of the third electrode region 23 are electrically independent and do not interfere with each other. In the present preferred embodiment, the sensing electrode structure of the third electrode region 23 shown in FIG. 4 includes an unsegmented sensing electrode 231, a sensing electrode 232 divided into two blocks, and a divided Four blocks of sensing electrodes 233, non-segmented sensing electrodes 231 pass signals through traces 431, two sensing blocks 232 pass signals through traces 432, and four blocks of sensing electrodes 233 transmits the signal through trace 433.
值得一提的是，由於該緩衝區走線42位於該緩衝區721，該第二緩衝區走線43位於該可視區71，兩區域皆有視覺透明的需求，故此兩種走線皆為氧化銦錫透明走線。 It is worth mentioning that since the buffer trace 42 is located in the buffer 721 and the second buffer trace 43 is located in the visible area 71, both areas have the need for visual transparency, so both types of traces are oxidized Indium tin transparent traces.
再者，考慮到氧化銦錫走線較一般金屬走線阻抗更高，因此其線寬較粗的問題，故在本發明一實施例中，該緩衝區走線42以及該第二緩衝區走線43為混合線結構，位於可視區71內的部份走線為透明走線，而位於油墨區72的部份走線為金屬走線，可以有效將低製造成本。 Furthermore, considering that the indium tin oxide trace has a higher resistance than a general metal trace, and therefore has a thicker line width, in an embodiment of the present invention, the buffer trace 42 and the second buffer trace The line 43 is a hybrid line structure. Some of the traces in the visible area 71 are transparent traces, while some of the traces in the ink region 72 are metal traces, which can effectively reduce manufacturing costs.
