Abstract
Description
本發明係有關於一種觸控螢幕之電極結構，特別是一種改良型之觸控螢幕之電極結構。The invention relates to an electrode structure of a touch screen, in particular to an electrode structure of an improved touch screen.
一般觸控螢幕的電極包含了傳送軸（Y軸）電極與接收軸（X軸）電極。傳送軸電極係電性連接至驅動電路，接收軸電極係電性連接至感測電路，之後再連接至微處理器，藉以感測計算出使用者手指在觸控螢幕上的按壓位置。The electrodes of the general touch screen include a transfer shaft (Y-axis) electrode and a receiving shaft (X-axis) electrode.

阻抗值與長度成正比，長度越長則阻抗值越大；電容值與X/Y軸交疊面積成正比，面積越大則電容值越大，而寬度相同時，長度越長亦即面積越大。上述接收軸電極常常由於長度過長，因此串聯阻抗與寄生電容過高，將導致觸控訊號減弱，影響了觸控螢幕的觸控效能。尤其是當觸控螢幕的尺寸越來越大的時候，串聯阻抗與寄生電容過高的情況將會越來越嚴重。The impedance value is proportional to the length. The longer the length, the larger the impedance value. The capacitance value is proportional to the X/Y axis overlap area. The larger the area, the larger the capacitance value. When the width is the same, the longer the length, the larger the area. Big. The above-mentioned receiving shaft electrode is often too long, so the series impedance and the parasitic capacitance are too high, which will cause the touch signal to be weakened, which affects the touch performance of the touch screen. Especially when the size of the touch screen is getting larger and larger, the series impedance and the parasitic capacitance are too high.

Adding the first figure to the second picture becomes the third picture.
本發明之改良型之觸控螢幕之電極結構包含複數之第一軸電極單元10及複數之第二軸電極單元20；該些第二軸電極單元20係相對於該些第一軸電極單元10設置。The electrode structure of the improved touch screen of the present invention comprises a plurality of first axis electrode units 10 and a plurality of second axis electrode units 20; the second axis electrode units 20 are opposite to the first axis electrode units 10 Settings.
該第二軸電極單元20包含一第一電極子單元202及一第二電極子單元204；該第一電極子單元202係相對於該第一軸電極單元10設置；該第二電極子單元202係相對於該第一軸電極單元10及該第一電極子單元202設置。The second axis electrode unit 20 includes a first electrode subunit 202 and a second electrode subunit 204; the first electrode subunit 202 is disposed relative to the first axis electrode unit 10; the second electrode subunit 202 It is disposed relative to the first axis electrode unit 10 and the first electrode subunit 202.
該第一電極子單元202包含一第一電極子單元第一長邊208、一第一電極子單元第二長邊210及一第一電極子單元短邊214。該第一電極子單元短邊214的兩端分別與該第一電極子單元第一長邊208的一端及該第一電極子單元第二長邊210的一端垂直連接。The first electrode sub-unit 202 includes a first long side 208 of a first electrode sub-unit, a second long side 210 of a first electrode sub-unit, and a short side 214 of a first electrode sub-unit. The two ends of the short side 214 of the first electrode subunit are perpendicularly connected to one end of the first long side 208 of the first electrode subunit and one end of the second long side 210 of the first electrode subunit.
該第二電極子單元204包含一第二電極子單元第一長邊218、一第二電極子單元第二長邊220及一第二電極子單元短邊222。該第二電極子單元短邊222的兩端分別與該第二電極子單元第一長邊218的一端及該第二電極子單元第二長邊220的一端垂直連接。The second electrode sub-unit 204 includes a first long side 218 of the second electrode sub-unit, a second long side 220 of the second electrode sub-unit, and a short side 222 of the second electrode sub-unit. The two ends of the short side 222 of the second electrode sub-unit are perpendicularly connected to one end of the first long side 218 of the second electrode sub-unit and one end of the second long side 220 of the second electrode sub-unit.
該第一電極子單元短邊214與該第二電極子單元短邊222之間具有一間隙226；該第一軸電極單元10的邊緣與該第二軸電極單元20的邊緣可為切齊或不切齊。A gap 226 is formed between the short side 214 of the first electrode subunit and the short side 222 of the second electrode subunit; the edge of the first shaft electrode unit 10 and the edge of the second shaft electrode unit 20 may be aligned or Not tangled.
該些第一軸電極單元10的數量為奇數且對稱地排列，使得中間的該第一軸電極單元10橫跨涵蓋該間隙226。The number of the first axial electrode units 10 is odd and symmetrically arranged such that the intermediate first axial electrode unit 10 spans the gap 226.
該第一軸電極單元10可為例如但不限定為一長方形；該第一電極子單元第一長邊208的長度可為例如但不限定等於該第一電極子單元第二長邊210的長度；該第二電極子單元第一長邊218的長度可為例如但不限定等於該第二電極子單元第二長邊220的長度；該第一電極子單元短邊214的長度可為例如但不限定等於該第二電極子單元短邊222的長度。The first axis electrode unit 10 can be, for example but not limited to, a rectangle; the length of the first long side 208 of the first electrode subunit can be, for example, but not limited to, equal to the length of the second long side 210 of the first electrode subunit. The length of the first long side 218 of the second electrode subunit may be, for example, but not limited to, the length of the second long side 220 of the second electrode subunit; the length of the short side 214 of the first electrode subunit may be, for example, It is not limited to be equal to the length of the short side 222 of the second electrode subunit.
本發明之功效在於改良觸控螢幕之電極結構之中央（以中間的該第一軸電極單元10橫跨涵蓋該間隙226）與邊界分界處（邊界分界處不設置第二軸電極；即，該第一電極子單元202及該第二電極子單元204不為封閉之長方形，而是為具有缺口之形狀），以提高觸控螢幕之穩定度、準確度及觸控效能。The effect of the present invention is to improve the center of the electrode structure of the touch screen (in the middle of the first axis electrode unit 10 across the gap 226) and the boundary boundary (the second axis electrode is not disposed at the boundary boundary; that is, the The first electrode sub-unit 202 and the second electrode sub-unit 204 are not closed rectangles, but have a notched shape to improve the stability, accuracy and touch performance of the touch screen.
當以中間的該第一軸電極單元10橫跨涵蓋該間隙226時，可改善電極中央處訊號過於微弱的缺點。當邊界分界處不設置第二軸電極時，即不會出現模擬兩可（可能在按壓處上方或下方）的訊號，可增加穩定度並減少誤判。When the first axial electrode unit 10 in the middle spans the gap 226, the disadvantage that the signal at the center of the electrode is too weak can be improved. When the second axis electrode is not set at the boundary boundary, the signal of the analog two (possibly above or below the pressing position) does not appear, which increases the stability and reduces the false positive.
須知如第三圖所示之本發明之改良型之觸控螢幕之電極結構係需再以電性連接至適當之驅動電路、感測電路及微處理器等等電子電路，藉以感測計算出使用者手指在觸控螢幕上的按壓位置；由於此部份屬於習知技藝，故於此不再贅述。本發明所述之觸控螢幕係指電容式觸控螢幕。It should be noted that the electrode structure of the improved touch screen of the present invention as shown in the third figure needs to be electrically connected to an appropriate electronic circuit such as a driving circuit, a sensing circuit and a microprocessor, thereby sensing and calculating The pressing position of the user's finger on the touch screen; since this part belongs to the prior art, it will not be described here. The touch screen of the present invention refers to a capacitive touch screen.
再者，亦須知如第三圖所示之本發明之該第一電極子單元202及該第二電極子單元204雖顯示具有缺口，但在實際產品上仍需為環繞閉合狀態，其接合處（該第一電極子單元202的左邊接合處，或是該第二電極子單元204的右邊接合處）需在觸控面板邊緣的作動區之外，或是在其後所連接之軟性電路板（flexible printed circuit，通常簡稱為FPC）。Moreover, it should be noted that the first electrode sub-unit 202 and the second electrode sub-unit 204 of the present invention, as shown in the third figure, are shown to have a gap, but the actual product still needs to be in a closed state, and the joint thereof (the left junction of the first electrode sub-unit 202, or the right junction of the second electrode sub-unit 204) needs to be outside the active area of the edge of the touch panel, or a flexible circuit board connected thereafter. (flexible printed circuit, usually referred to as FPC).
第一、二及三圖所示之該些第一軸電極單元10及該些第二軸電極單元20的數量僅為舉例，本發明並不以此為限，且該第一軸電極單元10可為例如但不限定為傳送軸（Y軸）電極，該第二軸電極單元20可為例如但不限定為接收軸（X軸）電極。The number of the first axis electrode unit 10 and the second axis electrode unit 20 shown in the first, second and third figures is only an example, and the invention is not limited thereto, and the first axis electrode unit 10 It may be, for example but not limited to, a transfer shaft (Y-axis) electrode, which may be, for example but not limited to, a receiving shaft (X-axis) electrode.
若該第一軸電極單元10為傳送軸電極，該第二軸電極單元20為接收軸電極，則該些第一軸電極單元10電性連接至驅動電路，該些第一電極子單元202電性連接至感測電路，且該些第二電極子單元204亦電性連接至感測電路，藉以感測計算出使用者手指在觸控螢幕上的按壓位置。If the first axis electrode unit 10 is a transmission axis electrode, and the second axis electrode unit 20 is a receiving axis electrode, the first axis electrode units 10 are electrically connected to the driving circuit, and the first electrode sub-units 202 are electrically connected. The second electrode sub-unit 204 is electrically connected to the sensing circuit, so as to sense the pressed position of the user's finger on the touch screen.
如先前技術所述，一般接收軸電極常常由於長度過長，因此串聯阻抗與寄生電容過高，將導致觸控訊號減弱，影響了觸控螢幕的觸控效能。本發明之另一功效在於，藉由本發明第三圖所示之電極結構，因為長度減半了（被分成該第一電極子單元202及該第二電極子單元204，且各自電性連接至感測電路），所以可降低串聯阻抗與寄生電容，藉以提高觸控螢幕的觸控效能。As described in the prior art, generally, the receiving axis electrode is often too long, so the series impedance and the parasitic capacitance are too high, which will cause the touch signal to be weakened, which affects the touch performance of the touch screen. Another effect of the present invention is that, by the electrode structure shown in the third figure of the present invention, the length is halved (divided into the first electrode sub-unit 202 and the second electrode sub-unit 204, and each is electrically connected to Sensing circuit), so the series impedance and parasitic capacitance can be reduced to improve the touch performance of the touch screen.

第四、五、六、七圖與第二、三圖類似，故相同處於此不再贅述；第四、五、六、七圖與第二、三圖不同處在於：該第一電極子單元202更包含複數之第一電極子單元補償電極228，該些第一電極子單元補償電極228係連接該第一電極子單元第一長邊208或該第一電極子單元第二長邊210；該第二電極子單元204更包含複數之第二電極子單元補償電極230，該些第二電極子單元補償電極230係連接該第二電極子單元第一長邊218或該第二電極子單元第二長邊220；該第一電極子單元補償電極228可為例如但不限定為方形（如第四、五圖所示）或L型（如第六、七圖所示）；該第二電極子單元補償電極230可為例如但不限定為方形（如第四、五圖所示）或L型（如第六、七圖所示）。The fourth, fifth, sixth, and seventh diagrams are similar to the second and third diagrams, so the same is not repeated here; the fourth, fifth, sixth, and seventh diagrams differ from the second and third diagrams in that the first electrode subunit The 202 further includes a plurality of first electrode sub-unit compensation electrodes 228, the first electrode sub-unit compensation electrodes 228 are connected to the first electrode sub-unit first long side 208 or the first electrode sub-unit second long side 210; The second electrode sub-unit 204 further includes a plurality of second electrode sub-unit compensation electrodes 230 connected to the first long side 218 or the second electrode sub-unit of the second electrode sub-unit The second long side 220; the first electrode subunit compensation electrode 228 can be, for example but not limited to, a square shape (as shown in the fourth and fifth figures) or an L type (as shown in the sixth and seventh figures); The electrode sub-unit compensation electrode 230 can be, for example but not limited to, a square shape (as shown in Figures 4 and 5) or an L-shape (as shown in Figures 6 and 7).
該第一電極子單元補償電極228及該第二電極子單元補償電極230的效用介紹如下：一般製作觸控螢幕之電極時，會在電極與電極之間的空間放置虛擬（dummy）區塊，其功能有二，第一是能平衡各電極的寄生電容，第二是作為補償光學視差之用；但是，製作此等虛擬區塊時，尤其是數量較多時，會增加電極蝕刻的困難度。因此本發明利用上述該些第一電極子單元補償電極228及該些第二電極子單元補償電極230取代一般之虛擬區塊，藉以達成減少電極蝕刻困難度之功效。再者，該些第一電極子單元202與該些第一電極子單元補償電極228之間的空間，以及該些第二電極子單元204與該些第二電極子單元補償電極230之間的空間，亦可放置少量之虛擬區塊，本發明不以此為限。The utility of the first electrode sub-unit compensation electrode 228 and the second electrode sub-unit compensation electrode 230 is as follows: when an electrode of a touch screen is generally fabricated, a dummy block is placed in a space between the electrode and the electrode. Its function is two, the first is to balance the parasitic capacitance of each electrode, and the second is to compensate for optical parallax; however, when making such virtual blocks, especially when the number is large, the difficulty of electrode etching is increased. . Therefore, the present invention utilizes the first electrode sub-unit compensation electrode 228 and the second electrode sub-unit compensation electrode 230 to replace the general virtual block, thereby achieving the effect of reducing electrode etching difficulty. Furthermore, a space between the first electrode sub-units 202 and the first electrode sub-unit compensation electrodes 228, and between the second electrode sub-units 204 and the second electrode sub-unit compensation electrodes 230 Space, a small number of virtual blocks may also be placed, and the invention is not limited thereto.
