Description
本發明是有關於一種靜電防護裝置，特別是有關於一種利用電阻變化誘發靜電放電之靜電防護裝置及具靜電防護之觸控裝置。The present invention relates to an electrostatic protection device, and more particularly to an electrostatic protection device that utilizes resistance change to induce electrostatic discharge and a touch device with electrostatic protection.
近年來，隨著面板技術的提昇及消費大眾對電子產品的使用普及化，觸控式面板的應用越來越廣泛，從早期的一些特殊用途，到目前許多電子產品都已逐漸採用觸控式面板，觸控式面板已經是一個當紅且快速成長的應用及市場。In recent years, with the improvement of panel technology and the popularization of the use of electronic products by consumers, touch panel applications have become more and more widely used. From some special applications in the early days, many electronic products have gradually adopted touch type. Panels, touch panels are already a popular and fast-growing application and market.
然而當消費者使用觸控式面板時，因操作模式常須以手指觸壓面板，使得手指上的靜電傳導至面板進而影響面板內之電路，這對通常耐壓只有幾十伏特的積體電路而言，實在是一大破壞，液晶螢幕模組本身螢幕和驅動元件等，都會受到靜電的破壞或影響，而靜電放電對於液晶螢幕模組的破壞直接觀察可發現一些損害情況，如造成螢幕缺陷、金屬導線被熔解、元件電阻值的改變、氧化層被破壞或擊穿以及影響以微處理器為中心的電子電路或控制器發生錯誤動作，這些都大大影響了觸控面板的使用壽命跟輸入訊號傳遞的可靠度。However, when the consumer uses the touch panel, it is often necessary to touch the panel with a finger due to the operation mode, so that the static electricity on the finger is transmitted to the panel and thus affects the circuit in the panel, which is an integrated circuit with a normal withstand voltage of only several tens of volts. In fact, it is a great destruction. The screen and drive components of the LCD screen module will be damaged or affected by static electricity. The electrostatic discharge can directly detect the damage of the LCD screen module, such as causing screen defects. The metal wire is melted, the resistance value of the component is changed, the oxide layer is broken or broken down, and the electronic circuit or controller that is centered on the microprocessor is malfunctioning, which greatly affects the life and input of the touch panel. The reliability of signal transmission.
就目前技術而言，可看到對抗靜電的相關解決方式，例如，新型專利第M434256號提供了現行較為普遍之觸控面板設計對於抗靜電能力提升做法，其係於面板最外圍部分加上一個導體迴路，旨在貼合軟性電路板後藉由電路板上的金屬線路接地到後端印刷電路板(或後端系統的地)，但在 此動作完成前觸控面板單體的累積靜電荷並無路徑可疏發而最終導致靜電放電擊傷此面板中的工作區是其缺點。而發明專利第I367052號揭露另一種面板抗靜電能力提升做法，其係利用尖端放電原理意將某區域的累積靜電荷耦合到其他導線以避免靜電放電擊傷，但此作法的缺點是各個導線之間的電荷耦和過程同時也會將訊號作耦合產生非必要性的耦合電訊號(雜訊)。As far as the current technology is concerned, a solution to the problem of antistatic can be seen. For example, the new patent No. M434256 provides a relatively common touch panel design for the antistatic ability improvement method, which is added to the outermost part of the panel. The conductor loop is designed to be attached to the flexible circuit board and grounded to the back end printed circuit board (or ground of the back end system) by the metal circuit on the board, but The cumulative static charge of the touch panel unit before this action is completed has no path to be thinned out and eventually causes the electrostatic discharge to damage the working area in the panel is a disadvantage. The invention patent No. I367052 discloses another method for improving the antistatic ability of a panel, which utilizes the principle of tip discharge to couple the accumulated static charge of a certain region to other wires to avoid electrostatic discharge damage, but the disadvantage of this method is that each wire is The inter-charge coupling process also couples the signals to produce non-essential coupled electrical signals (noise).
綜上，習知技術之抗靜電方式仍具多個待改進之處，如何發展一種可改善上述習知技術缺失，提升觸控面板抗靜電能力，保護觸控面板不受靜電傷害之靜電防護裝置及具靜電防護之觸控裝置，已成市場應用上之一個刻不容緩的議題。In summary, the antistatic method of the prior art still has a number of improvements, how to develop an electrostatic protection device that can improve the above-mentioned conventional technology, improve the antistatic ability of the touch panel, and protect the touch panel from static electricity. And the touch device with static protection has become an urgent issue in the market.

In this embodiment, the first conductive segments 11 and the second conductive segments 12 are preferably arranged in phase. However, such an interphase arrangement is merely an example and not a limitation, and in practice, it is not limited to this arrangement.
該等第一導電區段11之每一者可具有一第一金屬導線111；該等第二導電區段12之每一者較佳可具有複數個第二金屬導線121。在本實施例中，該等第二金屬導線121之每一者的截面積較佳可小於該等第一金屬導線111之每一者的截面積。也就是說，該等第二金屬導線121之每一者的電阻較佳可不同於該等第一金屬導線111之每一者的電阻，使得第一金屬導線111與第二金屬導線121之間具有電阻的急遽變化。在實際實施時，第一金屬導線111的截面直徑較佳可實施在60至250微米(μm)之間，而第二金屬導線121的截面直徑較佳可實施在2至20微米之間。Each of the first conductive segments 11 can have a first metal wire 111; each of the second conductive segments 12 preferably has a plurality of second metal wires 121. In this embodiment, the cross-sectional area of each of the second metal wires 121 is preferably smaller than the cross-sectional area of each of the first metal wires 111. That is, the resistance of each of the second metal wires 121 may preferably be different from the resistance of each of the first metal wires 111 such that the first metal wire 111 and the second metal wire 121 are between Has a rapid change in resistance. In actual implementation, the cross-sectional diameter of the first metal wire 111 may preferably be between 60 and 250 micrometers (μm), and the cross-sectional diameter of the second metal wire 121 may preferably be between 2 and 20 micrometers.

Alternatively, the resistance values of the first metal wires 111 are equal to each other, and the resistance values of the second metal wires 121 are equal to each other, wherein the resistance value includes a resistance value or an impedance value.
請參閱第二圖，其係本發明之靜電防護裝置一第二實施例之部分結構示意圖，用以說明本發明之靜電防護裝置的另一基本實施方式與其相應結構之實施。第二實施例之靜電防護裝置的基本實施主要係類同於第一實施例的基本實施。Please refer to the second drawing, which is a partial structural diagram of a second embodiment of the electrostatic protection device of the present invention for explaining the implementation of another basic embodiment of the electrostatic protection device of the present invention and its corresponding structure. The basic implementation of the electrostatic protection device of the second embodiment is mainly analogous to the basic implementation of the first embodiment.
然值得注意的是，相較於第一實施例，在本實施例中，該等第二金屬導線121彼此之間的體積大小可彼此不相同，且每一個第二金屬導線121的形狀態樣皆可有所變化。如第二圖中所例示之第二金屬導線121的實施態樣；然實際實施時，並不僅限於此一態樣。It should be noted that, in the present embodiment, the volume of the second metal wires 121 may be different from each other, and the shape of each of the second metal wires 121 is different from that of the first embodiment. All can be changed. The embodiment of the second metal wire 121 as illustrated in the second figure; however, the actual implementation is not limited to this aspect.
此外，第一金屬導線111以及第二金屬導線121較佳可至少由銅、鉬、鋁及氧化銦錫(Indium Tin Oxide，ITO)等其中之一者所構成。在本發明所屬領域中具有通常知識者應當明瞭，前述構成之材料態樣僅為舉例而非限制，實際實施時，並不僅限於上述之態樣。In addition, the first metal wire 111 and the second metal wire 121 are preferably made of at least one of copper, molybdenum, aluminum, and indium tin oxide (ITO). It is to be understood by those skilled in the art that the present invention is not limited by the scope of the invention.
請參閱第三圖，其係本發明具靜電防護之觸控裝置一第一實施例之產品示意圖，用以接續說明本發明之具靜電防護之觸控裝置的基本實用方式。本發明提出的靜電防護裝置1可設置於觸控裝置3上。如圖所示，觸控裝置3至少可包含一觸控面板31以及靜電防護裝置1。該靜電防護裝置1較佳可設置在該觸控面板31的四周圍；且靜電防護裝置1之一端13可透過一連接電路32與該觸控面板31電性連接，而該靜電防護裝置1之另一端14可與接地端(Ground)電性連接。Please refer to the third figure, which is a schematic diagram of a first embodiment of the touch protection device with electrostatic protection according to the present invention, for illustrating the basic practical manner of the electrostatic protection touch device of the present invention. The electrostatic protection device 1 proposed by the present invention can be disposed on the touch device 3. As shown in the figure, the touch device 3 can include at least one touch panel 31 and an electrostatic protection device 1 . The electrostatic protection device 1 is preferably disposed around the touch panel 31. The one end 13 of the electrostatic protection device 1 can be electrically connected to the touch panel 31 through a connection circuit 32. The other end 14 can be electrically connected to the ground (Ground).
請參閱第四圖，其係本發明具靜電防護之觸控裝置一第二實施例之產品示意圖，用以說明本發明又一具靜電防護之觸控裝置的相應結構。第二實施例之具靜電防護之觸控裝置的基本實施主要係類同於第一實施例的基本實施。Please refer to the fourth figure, which is a schematic view of a second embodiment of the touch protection device with electrostatic protection according to the present invention, for explaining the corresponding structure of another electrostatic protection touch device of the present invention. The basic implementation of the electrostatic protection touch device of the second embodiment is mainly similar to the basic implementation of the first embodiment.
然不同的是，相較於第一實施例，如圖所示，在本實施例中，觸控裝置3進一步可包含另一靜電防護裝置4。該另一靜電防護裝置4之一端41可透過一連接電路32與該觸控面板31電性連接，而該另一靜電防護裝置4之另一端42可與接地端(Ground)電性連接。其中，該另一靜電防護裝置4的結構可同本發明靜電防護裝置1，或該另一靜電防護裝置4的結構可為一般的金屬導線。在本發明所屬領域中具有通常知識者應當明瞭，該另一靜電防護裝置4的結構態樣僅為舉例而非限制，實際實施時，並不僅限於上述之示例。The difference is that, compared to the first embodiment, as shown in the figure, in the embodiment, the touch device 3 may further comprise another electrostatic protection device 4. One end 41 of the other ESD device 4 is electrically connected to the touch panel 31 through a connecting circuit 32, and the other end 42 of the other ESD device 4 is electrically connected to a ground (Ground). The structure of the other electrostatic protection device 4 can be the same as that of the electrostatic protection device 1 of the present invention, or the structure of the other electrostatic protection device 4 can be a general metal wire. It should be understood by those of ordinary skill in the art to which the present invention pertains that the structural form of the other electrostatic protection device 4 is merely an example and not a limitation, and in actual implementation, it is not limited to the above examples.
請參閱第五圖，其係本發明靜電防護裝置之靜電放電示意圖，用以說明本發明之靜電防護裝置的結構實施與其靜電放電方式。如圖所示，當一微小電流51從第一金屬導 線111往第二金屬導線121流動時，因第一金屬導線111與第二金屬導線121截面積大小之差異，使得此處的電阻產生急遽的變化，因而誘發靜電在第二金屬導線121放電。也就是說，本發明靜電防護裝置1可將非期望的靜電放電傷害引導至非有效區，來保護觸控面板不受靜電傷害。Please refer to the fifth figure, which is a schematic diagram of electrostatic discharge of the electrostatic protection device of the present invention, for explaining the structural implementation of the electrostatic protection device of the present invention and its electrostatic discharge mode. As shown, when a tiny current 51 is from the first metal guide When the line 111 flows toward the second metal wire 121, the difference in the cross-sectional area of the first metal wire 111 and the second metal wire 121 causes a sharp change in the resistance here, thereby causing static electricity to be discharged in the second metal wire 121. That is to say, the electrostatic protection device 1 of the present invention can guide undesired electrostatic discharge damage to the non-active area to protect the touch panel from static electricity.
所以在使用者使用本發明具靜電防護之觸控裝置3，因操作行為使得手指上的靜電傳導至觸控面板31上時，因其面板外圍連接了靜電防護裝置1，使得操作導致的預期外靜電較容易在第二金屬導線121放電。也就是說，非期望的靜電放電傷害因被引導並侷限至第二金屬導線121(即非有效區)，對觸控面板31本身並不會造成任何傷害，例如觸控面板31本身之螢幕和驅動元件等等，都不會受到靜電的破壞或影響；如此將有效提升觸控面板31的抗靜電能力。Therefore, when the user uses the touch protection device 3 with electrostatic protection according to the present invention, when the static electricity on the finger is transmitted to the touch panel 31 due to the operation behavior, the electrostatic protection device 1 is connected to the periphery of the panel, so that the operation is unexpected. Static electricity is more likely to discharge at the second metal wire 121. That is to say, the undesired electrostatic discharge damage is guided and confined to the second metal wire 121 (ie, the inactive area), and does not cause any damage to the touch panel 31 itself, such as the screen of the touch panel 31 itself. The driving element and the like are not damaged or affected by static electricity; this will effectively improve the antistatic capability of the touch panel 31.
值得一提的是，在本發明所屬領域中具有通常知識者應當明瞭，前面描述之第一金屬導線111及第二金屬導線121之形狀、數量、構成材料及排列方式等、靜電防護裝置1實施於觸控裝置3上之態樣等僅為舉例而非限制，任何未脫離本靜電防護裝置1及具靜電防護之觸控裝置之精神與範疇，均應被包含於本發明之精神，在此先行敘明。It should be noted that those having ordinary knowledge in the field to which the present invention pertains should be aware of the shape, the number, the constituent materials, the arrangement and the like of the first metal wire 111 and the second metal wire 121 described above, and the electrostatic protection device 1 is implemented. The aspects and the like on the touch device 3 are merely examples and are not limiting. Any spirit and scope of the touch device not deviating from the static protection device 1 and having electrostatic protection should be included in the spirit of the present invention. Explain first.
綜上所述，本發明所提出之靜電防護裝置及具靜電防護之觸控裝置可在觸控面板的外圍導體佈線上提供多個靜電誘發處，以將非期望的靜電放電傷害引導至非有效區。如此，將可有效提升觸控面板的抗靜電能力，保護觸控面板不受靜電傷害造成的損失。In summary, the electrostatic protection device and the electrostatic protection touch device provided by the present invention can provide a plurality of static electricity induction points on the peripheral conductor wiring of the touch panel to guide undesired electrostatic discharge damage to the non-effective one. Area. In this way, the antistatic capability of the touch panel can be effectively improved, and the touch panel can be protected from the damage caused by static electricity.
