Description

觸控裝置Touch device

本發明是有關於一種電子裝置，且特別是有關於一種觸控裝置。The invention relates to an electronic device, and more particularly to a touch device.

近年來，隨著資訊技術、無線行動通訊和資訊家電等各項應用的快速發展，為了達到更便利、體積更輕巧化以及更人性化的目的，許多資訊產品的輸入裝置已由傳統的鍵盤或滑鼠轉變為觸控面板。一般而言，若以感測原理分類，觸控面板的感測方式大致可區分為電阻式、電容式、光學式、聲波式及電磁式等。以電容式觸控面板為例，根據其動與感測方式可分為自電容式（self capacitive）觸控面板及互電容式（mutual capacitive）觸控面板。In recent years, with the rapid development of various applications such as information technology, wireless mobile communications and information appliances, in order to achieve more convenience, lighter size and more humane purposes, the input devices of many information products have been replaced by traditional keyboards or The mouse turns into a touch panel. Generally speaking, if classified according to the sensing principle, the sensing methods of the touch panel can be roughly divided into resistive, capacitive, optical, acoustic, electromagnetic, etc. Taking a capacitive touch panel as an example, it can be divided into a self capacitive touch panel and a mutual capacitive touch panel according to its motion and sensing methods.

互電容式觸控面板包括沿著X軸方向延伸的多個第一觸控電極及沿著Y軸方向延伸的多個第二觸控電極，其中X軸方向與Y軸方向不同。當物體（例如:觸控筆）觸碰觸控面板時，會改變第一、二觸控電極之間的電容；將此改變訊號回傳至控制器，即可計算接觸發生點的座標。然而，當第一、二觸控電極之間的互電容過大時，會影響物體（例如:觸控筆）操作觸控面板。The mutual capacitance type touch panel includes a plurality of first touch electrodes extending along the X axis direction and a plurality of second touch electrodes extending along the Y axis direction, wherein the X axis direction is different from the Y axis direction. When an object (such as a stylus) touches the touch panel, it will change the capacitance between the first and second touch electrodes; this change signal is sent back to the controller to calculate the coordinates of the point where the contact occurred. However, when the mutual capacitance between the first and second touch electrodes is too large, it will affect the operation of the touch panel by an object (such as a stylus).

In this way, the mutual capacitance of the first touch electrode 142 and the second touch electrode 242 is low, which facilitates the touch pen to operate the touch device 10.

此外，在本實施例中，第一觸控電極142與第二觸控電極242之間除了設有黏著層3外，還設有絕緣層150、偏光片260及/或覆蓋層250，而進一步增加第一觸控電極142與第二觸控電極242之間的距離。藉此，第一觸控電極142與第二觸控電極242的互電容可進一步降低，有利於觸控筆操作觸控裝置10。In addition, in this embodiment, in addition to the adhesive layer 3 provided between the first touch electrode 142 and the second touch electrode 242, an insulating layer 150, a polarizer 260 and/or a cover layer 250 are further provided.

圖5示出本發明一實施例之互相交錯的一條第一金屬線142a及一條第二金屬線242a。圖5對應圖4的區域I。FIG. 5 shows a first metal line 142a and a second metal line 242a interlaced with each other according to an embodiment of the present invention. Figure 5 corresponds to area I in Figure 4.

圖6為本發明一實施例之互相交錯的一條第一金屬線142a及一條第二金屬線242a之交錯處的放大示意圖。圖6對應圖5的區域i。FIG. 6 is an enlarged schematic diagram of the intersection of a first metal line 142a and a second metal line 242a that are interlaced with each other according to an embodiment of the present invention. Figure 6 corresponds to area i in Figure 5.

請參照圖4、圖5及圖6，值得注意的是，第一金屬線142a具有多個第一粗部142a-1和連接於多個第一粗部142a-1之間的第一細部142a-2，第一細部142a-2的線寬C小於第一粗部142a-1的線寬B，第一金屬線142a的第一細部142a-2與第二金屬線242a交錯且互相重疊。也就是說，第一觸控電極142在其與第二觸控電極242交錯處的線寬變小，而使第一觸控電極142與第二觸控電極242的重疊面積變少。藉此，第一觸控電極142與第二觸控電極242的互電容可降低，有助於觸控筆操作觸控裝置10（標示於圖1）。4, 5 and 6, it is worth noting that the first metal wire 142a has a plurality of first thick portions 142a-1 and a first thin portion 142a connected between the plurality of first thick portions 142a-1 -2, the line width C of the first thin portion 142a-2 is smaller than the line width B of the first thick portion 142a-1, and the first thin portion 142a-2 of the first metal wire 142a and the second metal wire 242a are staggered and overlap each other. That is, the line width of the first touch electrode 142 at the intersection of the first touch electrode 142 and the second touch electrode 242 becomes smaller, so that the overlapping area of the first touch electrode 142 and the second touch electrode 242 becomes smaller. Thereby, the mutual capacitance of the first touch electrode 142 and the second touch electrode 242 can be reduced, which helps the stylus to operate the touch device 10 (marked in FIG. 1).

在本實施例中，第二金屬線242a可選擇性地具有多個第二粗部242a-1以及連接於多個第二粗部242a-1之間的第二細部242a-2，第二細部242a-2的線寬D小於第二粗部242a-1的線寬A，第一金屬線142a的第一細部142a-2與第二金屬線242a的第二細部242a-2交錯且互相重疊。也就是說，在本實施例中，第二觸控電極242在其與第一觸控電極142交錯處的線寬也可以變小，而使第一觸控電極142與第二觸控電極242的重疊面積進一步變小。藉此，第一觸控電極142與第二觸控電極242的互電容可更進一步降低，有助於觸控筆操作觸控裝置10（標示於圖1）。In this embodiment, the second metal wire 242a may optionally have a plurality of second thick portions 242a-1 and a second thin portion 242a-2 connected between the plurality of second thick portions 242a-1. The line width D of the 242a-2 is smaller than the line width A of the second thick portion 242a-1, and the first thin portion 142a-2 of the first metal wire 142a and the second thin portion 242a-2 of the second metal wire 242a are staggered and overlap each other. That is to say, in this embodiment, the line width of the second touch electrode 242 where it intersects with the first touch electrode 142 can also be reduced, so that the first touch electrode 142 and the second touch electrode 242 The overlapping area is further reduced. In this way, the mutual capacitance of the first touch electrode 142 and the second touch electrode 242 can be further reduced, which facilitates the operation of the touch device 10 by the stylus (marked in FIG. 1 ).

然而，本發明不限於此，在其它實施例中，第二觸控電極242的第二金屬線242a也可具有一致的線寬。However, the present invention is not limited to this. In other embodiments, the second metal line 242a of the second touch electrode 242 may also have a uniform line width.

The axis x1 of the detail 142a-2 has an included angle α1. That is to say, the axis X1 of the two adjacent first thick portions 142a-1 of the same first metal wire 142a are not on the same straight line and are misaligned with each other, and between the two axes X1 of the two adjacent first thick portions 142a-1 There is an offset S1. Similarly, in this embodiment, a second thin portion 242a-2 is connected between two adjacent second thick portions 242a-1, and the axis X2 of the second thick portion 242a-1 and the second thin portion 242a-2 The axis x2 has an included angle α2. In other words, the axis X2 of the two adjacent second thick portions 242a-1 of the same second metal wire 242a are not on the same straight line and are misaligned with each other, and between the two axis X2 of the two adjacent second thick portions 242a-1 There is an offset S2. For example, in this embodiment, 0 ^o > α1 ≤ 15 ^o ; 0 ^o > α2 ≤ 15 ^o ; but the present invention is not limited thereto.
