A light guide surface 121 of the light guide plate 12 is guided and turned by the light guide plate 12 to form a surface light source that emits upward light.
再則,該觸控板1更包括一透光接觸結構14,設置於該些LED發光元件13及該導光板12之上方,以供一使用者於該透光接觸結構14進行一觸控操作;其中,該透光接觸結構14至少包括:設置於該導光板上方之一遮罩層141,位於該遮罩層141上方且用以擴散並均勻化該些LED光線之一擴散層142,以及位於該擴散層142上方之一透光板143;其中,該遮罩層141設置有複數透光圖案1411(如圖1B所示者),且該些LED光線穿透該些透光圖案1411、該擴散層142與該透光板143之後,可供該使用者於該透光板143之一透光表面1431進行該觸控操作。 Furthermore, the touch panel 1 further includes a light-transmitting contact structure 14 disposed above the LED light-emitting elements 13 and the light guide plate 12 for a user to perform a touch operation on the light-transmitting contact structure 14 ; Wherein, the light-transmitting contact structure 14 at least includes: a mask layer 141 disposed above the light guide plate, a diffusion layer 142 located above the mask layer 141 and used to diffuse and homogenize the LED light, and A light-transmitting plate 143 is located above the diffusion layer 142; wherein, the mask layer 141 is provided with a plurality of light-transmitting patterns 1411 (as shown in FIG. 1B), and the LED light penetrates the light-transmitting patterns 1411.

習知具按鍵輸入功能的觸控板1之缺失,在於該些LED發光元件13與該觸控感測層11之間的設置關係,導致了該使用者在該觸控感測層11之部分區域上方進行該觸控操作時,會額外需要進行一些特別的感測補償程序,該觸控板1才能有效且正確地偵測或感測到該使用者以其手指或物件於該透光表面1431進行的部分觸控操作。 The shortcoming of the conventional touch panel 1 with key input function lies in the arrangement relationship between the LED light-emitting elements 13 and the touch sensing layer 11 , resulting in the user's part in the touch sensing layer 11 When performing the touch operation above the area, some additional special sensing compensation procedures will be required so that the touch panel 1 can effectively and correctly detect or sense the user's fingers or objects on the light-transmitting surface. Some touch operations performed by 1431.
申言之,請參閱圖1C,其係為習知具按鍵輸入功能的觸控板1中有關該些LED發光元件13、該電路板10、與該觸控感測層11中之複數觸控感測單元間之設置關係的概念示例圖;其中,本案以位於該上方板體表面101之該觸控感測層11中的觸控感測單元111、112、113,搭配 該些LED發光元件13中之LED發光元件131、132為例,進行一簡要說明。 In other words, please refer to FIG. 1C , which illustrates the plurality of touch controls in the LED light-emitting elements 13 , the circuit board 10 , and the touch sensing layer 11 in a conventional touch panel 1 with a key input function. Conceptual example diagram of the arrangement relationship between sensing units; in this case, the touch sensing units 111, 112, and 113 located in the touch sensing layer 11 on the upper plate surface 101 are used together with The LED light-emitting elements 131 and 132 among the LED light-emitting elements 13 are taken as an example for a brief description.
自圖1C可知,該觸控感測單元111包括一感測線路區域1111與一驅動線路區域1112;其中,該感測線路區域1111與該驅動線路區域1112係彼此以內外環狀方式相鄰設置的封閉式銅箔導線區域,並共同形成一電容感測結構。 As can be seen from FIG. 1C , the touch sensing unit 111 includes a sensing circuit area 1111 and a driving circuit area 1112; wherein the sensing circuit area 1111 and the driving circuit area 1112 are adjacent to each other in an inner and outer annular manner. of enclosed copper foil conductor areas, and together form a capacitive sensing structure.
同理,該觸控感測單元112包括一感測線路區域1121與一驅動線路區域1122,且該觸控感測單元113包括一感測線路區域1131與一驅動線路區域1132。 Similarly, the touch sensing unit 112 includes a sensing circuit area 1121 and a driving circuit area 1122, and the touch sensing unit 113 includes a sensing circuit area 1131 and a driving circuit area 1132.
以該LED發光元件131焊接設置於該觸控感測單元111及該觸控感測單元112之間為例,由於該LED發光元件131之一第一固定焊點1311會影響到該觸控感測單元111之該感測線路區域1111與該驅動線路區域1112的部分區域,因此,該觸控感測單元111勢必需要修飾去除部分受到影響的銅箔導線,如此才能提供該第一固定焊點1311設置於其中。 Taking the LED light-emitting element 131 being welded and disposed between the touch sensing unit 111 and the touch sensing unit 112 as an example, since one of the first fixed solder joints 1311 of the LED light-emitting element 131 will affect the touch feeling. Partial areas of the sensing circuit area 1111 and the driving circuit area 1112 of the touch sensing unit 111. Therefore, the touch sensing unit 111 must modify and remove part of the affected copper foil wires in order to provide the first fixed solder joint. 1311 is set in it.
另外,由於該LED發光元件131之一第二固定焊點1312也會影響到該觸控感測單元112之該感測線路區域1121與該驅動線路區域1122之部分區域,因此,該觸控感測單元112勢必也同樣需要修飾去除部分受到影響的銅箔導線,才能提供該第二固定焊點1312設置於其中。 In addition, since one of the second fixed solder joints 1312 of the LED light-emitting element 131 will also affect part of the sensing circuit area 1121 and the driving circuit area 1122 of the touch sensing unit 112, therefore, the touch sense The measuring unit 112 must also modify and remove some of the affected copper foil wires in order to provide the second fixed solder joint 1312 therein.
但如此一來,該觸控感測單元111及該觸控感測單元112中可供進行觸控感測的銅箔導線面積,會明顯小於該觸控感測單元113中可供進行觸控感測的銅箔導線面積,此即意味著該觸控感測單元111或該觸控感測單元112的電容感測效應,會明顯不同於該觸控感測單元113的電容感測效應,是以,針對該觸控感測單元111及該觸控感測單元112的上述問題,該觸控板1勢必額外需要進行一些特別的感測補償程序,才能有 效且正確地偵測或感測到當該使用者以其手指或物件移動到該觸控感測單元111或該觸控感測單元112之上方位置時的一些觸控操作。 However, in this way, the area of copper foil wires available for touch sensing in the touch sensing unit 111 and the touch sensing unit 112 will be significantly smaller than that of the touch sensing unit 113 available for touch sensing. The sensed copper foil conductor area, which means that the capacitive sensing effect of the touch sensing unit 111 or the touch sensing unit 112 will be significantly different from the capacitive sensing effect of the touch sensing unit 113. Therefore, in order to achieve the above-mentioned problems of the touch sensing unit 111 and the touch sensing unit 112 , the touch panel 1 must perform some additional special sensing compensation procedures. Effectively and correctly detect or sense some touch operations when the user moves his finger or object to a position above the touch sensing unit 111 or the touch sensing unit 112 .
簡言之,習知作法會額外增加該觸控板1的實施成本與複雜度,也因此,如何提供一種更簡單的實施方式,以使該些LED發光元件13固定於該觸控感測層11時,不會影響到該觸控感測層11的電容感測效應,即成為本案欲解決的主要技術課題。 In short, the conventional approach will additionally increase the implementation cost and complexity of the touch panel 1. Therefore, how to provide a simpler implementation to fix the LED light-emitting elements 13 on the touch sensing layer 11, the capacitive sensing effect of the touch sensing layer 11 will not be affected, which becomes the main technical issue to be solved in this case.

The sensing unit 512, a sensing circuit area 5131 and a driving circuit area 5132 of the touch sensing unit 513 are welded to a blank area 5133 of the touch sensing unit 513.
根據上述可知,本案將複數LED發光元件結合至具按鍵輸入功能的觸控板之同時,並不會影響到原本觸控板的電容感測效應,如此一來,本案即可使觸控板不必額外進行任何的感測補償程序,就能夠有效且正確地偵測或感測到該使用者在觸控板中任何區域所進行的觸控操作;故本案實為一極具產業價值之作。 According to the above, it can be seen that while this case combines multiple LED light-emitting elements into a touch panel with key input function, it will not affect the capacitive sensing effect of the original touch panel. In this way, this case can eliminate the need for the touch panel. By performing any additional sensing compensation procedures, the user's touch operation in any area of the touch panel can be effectively and accurately detected or sensed; therefore, this case is indeed a work of great industrial value.
