Abstract

This invention relates to an electrostatic discharge protection circuit, particularly a protection circuit used in LCD panel. It can prevent the damage of driving circuit due to electrostatic discharge (ESD) effect. Mainly, the ending terminal of each driving circuit on the display panel has a tip part formed, and the panel edge side corresponding to the tip part has at least a discharge electrode. The ending terminal of the discharging electrode also has a tip part of discharging electrode corresponding to the tip part of each driving circuit. Thus, when the driving circuit has static charges, the tip part releases the static charges to the corresponding discharging electrode. It prevents the driving circuit and the connected electronic components from being damaged by the sudden large current. It not only simplifies the manufacturing process, but also saves the cost.

1231159 五、發明說明（5) --- 一放電電極27或第二放電電極29，且於第一放電電極27 終端位置形成有一第一電極尖端部271，該第一電極尖端部271鄰近於資料匯流排線21之第一尖端部2n，且相互面對。同理，第二放電電極29之終端位置同樣形成有一第二電極尖端部291，該第二電極尖端部291鄰近於閘極匯流排線2 3之第二尖端部2 31，且相互面對。當閘極匯流排線2 3因摩擦或其他原因而局部帶有靜電電荷時’該靜電電荷即可透過閘極匯流排線2 3之第二尖端部2 31而緩慢放電至與其相對應之第二電極尖端部2 g j及第二放電電極2 9中’藉此以避免閘極匯流排線2 3因靜電電荷充電至一定程度時’瞬間放電至鄰近之閘極匯流排線2 3、資料匯流排線2 1或與其電性連設之電子元件，藉此以達到保護驅動電路之目的。當然，於閘極匯流排線23透過第二尖端部231而放電至相對應之第二電極尖端部291及第二放電電極29時，亦可能因此造成第二尖端部231、第二電極尖端部291或第二放電電極29之損害，但是此損害區域僅止於第二尖端部23 1及對應之第二放電電極29之鄰近區域，而該區域可設計於面板邊側之板邊無效區2 5 1内，並不會損及中央線路區 253内之電子元件及驅動電路，所以完全不影響使用者之目視效果。同理，對資料匯流排線2 1之放電作用及達成效果亦然，茲不贅述。本發明由於將可能受到靜電放電效應毁損之第一尖端部211、第一放電電極27、第一電極尖端部271、第二尖端1231159 V. Description of the invention (5) --- A discharge electrode 27 or a second discharge electrode 29, and a first electrode tip portion 271 is formed at the terminal position of the first discharge electrode 27, and the first electrode tip portion 271 is adjacent to the data The first tip portions 2n of the bus bars 21 face each other. Similarly, a second electrode tip portion 291 is also formed at the terminal position of the second discharge electrode 29. The second electrode tip portion 291 is adjacent to the second tip portion 2 31 of the gate bus bar 23 and faces each other. When the gate bus bar 23 is locally charged with static electricity due to friction or other reasons, the electrostatic charge can be slowly discharged through the second tip portion 2 31 of the gate bus bar 23 to the corresponding one. The two-electrode tip 2 gj and the second discharge electrode 29 are used to prevent the gate busbars 2 3 from being charged to a certain extent due to electrostatic charges. The cable 21 or an electronic component electrically connected thereto is used to protect the driving circuit. Of course, when the gate bus bar 23 is discharged through the second tip portion 231 to the corresponding second electrode tip portion 291 and the second discharge electrode 29, the second tip portion 231 and the second electrode tip portion may also be caused accordingly. 291 or the second discharge electrode 29, but this damage area is only limited to the adjacent area of the second tip portion 23 1 and the corresponding second discharge electrode 29, and this area can be designed in the panel edge invalid area 2 of the panel side Within 51, the electronic components and driving circuits in the central circuit area 253 will not be damaged, so it will not affect the visual effect of the user at all. In the same way, the discharge effect and effectiveness of the data bus 21 are the same, so I will not repeat them here. In the present invention, the first tip portion 211, the first discharge electrode 27, the first electrode tip portion 271, and the second tip which may be damaged by the electrostatic discharge effect

第9頁 1231159 五、發明說明（6) 部231、第二放電電極29及第二電極尖端部291固設於不影響使用者目視效果之板邊無效區251内，且第一尖端部2Π 與第一電極尖端部271之間、及第二尖端部231與第二電極大知部2 9 1之間並不會直接接觸，因此，在面板驅動電路完成後並無需一定要進行板邊無效區251及中央線路區253 之切割程序，因此，不僅可簡化製作流程，又可相對降低資源之浪費及節省成本支出者。最後，請參閱第3圖，係本發明另一實施例之構造示意圖；如圖所示，其主要係將每一個第二放電電極2 9之間以一第二放電電路313予以串接，而每一個第一放電電極 2 7之間則以一第一放電電路3 11予以串接，另外，再以一限流電阻315將第一放電電路311及第二放電電路313予以電性連接，如此即可使整個放電電路處於同一電位，更可增強其放電平衡效果。當然，每一條閘極匯流排線2 3設有多少個第二尖端部 231 ’或每一個第二放電電極29設有多少個第二電極尖端部2 91，皆可透過所使用之材料、線路之安排、面板之大小等不同之狀態來加以計算及設計，而不限定其數目。同理’資料匯流排線2 1之第一尖端部211數量及第一放電電極27之第一電極尖端部271數量亦可依實際需要而設置不同之數量。另外’此種靜電防護電路亦可選擇僅設置於閑極匯流排線23，或僅設置於資料匯流排線2 1。又，此種靜電防護電路不僅可適用於薄膜液晶顯示器 (TFT-LCD) ’更可適用於扭轉型向列液晶顯示器、超扭轉Page 9 of 1231159 V. Description of the invention (6) The part 231, the second discharge electrode 29 and the second electrode tip portion 291 are fixed in the invalid area 251 of the board edge which does not affect the visual effect of the user, and the first tip portion 2Π and There is no direct contact between the first electrode tip portion 271 and the second tip portion 231 and the second electrode dachi portion 2 91. Therefore, it is not necessary to perform a board edge ineffective area after the panel driving circuit is completed. The cutting procedures of 251 and central line area 253 can not only simplify the production process, but also reduce the waste of resources and save the cost. Finally, please refer to FIG. 3, which is a schematic structural diagram of another embodiment of the present invention. As shown in the figure, each of the second discharge electrodes 29 is connected in series by a second discharge circuit 313, and Each first discharge electrode 27 is connected in series by a first discharge circuit 3 11. In addition, the first discharge circuit 311 and the second discharge circuit 313 are electrically connected by a current limiting resistor 315. That is, the entire discharge circuit can be at the same potential, and the discharge balancing effect can be enhanced. Of course, how many second tip portions 231 ′ are provided for each gate bus bar 23 or how many second electrode tip portions 2 91 are provided for each second discharge electrode 29 can be passed through the materials and lines used. The arrangement, the size of the panel, etc. can be calculated and designed without limiting the number. Similarly, the number of the first tip portions 211 of the data bus bar 21 and the number of the first electrode tip portions 271 of the first discharge electrode 27 may be set to different numbers according to actual needs. In addition, this kind of electrostatic protection circuit can also be provided only on the bus bar 23 of the idler, or only on the bus bar 21 of the data. In addition, such an electrostatic protection circuit can be applied not only to a thin film liquid crystal display (TFT-LCD), but also to a twisted nematic liquid crystal display and a super twisted
