Abstract
Description
本新型創作是有關於一種電路板與顯示模組，且特別是有關於一種可撓式印刷電路板與觸控顯示模組。The present invention relates to a circuit board and a display module, and more particularly to a flexible printed circuit board and a touch display module.
隨著資訊技術、無線行動通訊和資訊家電的快速發展與應用，為了達到攜帶便利、體積輕巧化以及操作人性化的目的，許多資訊產品已由傳統之鍵盤或滑鼠等輸入裝置，轉變為使用觸控面板作為輸入裝置。目前，觸控面板大致可區分為電阻式、電容式、紅外線式及超音波式等觸控面板，其中以電阻式觸控面板與電容式觸控面板為最常見的產品。With the rapid development and application of information technology, wireless mobile communication and information appliances, many information products have been transformed from traditional keyboards or mouse input devices to use for the convenience of portability, light weight and user-friendly operation. The touch panel is used as an input device. Currently, touch panels can be roughly classified into resistive, capacitive, infrared, and ultrasonic touch panels. Among them, resistive touch panels and capacitive touch panels are the most common products.
觸控面板往往被安裝於顯示面板上方。如此一來，使用者可以直接點選顯示面板所顯示圖像來進行觸控操作。因此，觸控面板與顯示面板必須分別藉由一片可撓式印刷電路板連接各自的驅動電路。如圖1所示，顯示面板110是藉由可撓式印刷電路板120連接至驅動電路板130，觸控面板140則藉由可撓式印刷電路板150連接至驅動電路板130。驅動電路板130上設置了顯示面 板110的驅動晶片132與觸控面板140的驅動晶片134。然而，顯示面板110使用可撓式印刷電路板120，觸控面板140使用可撓式印刷電路板150。如此一來，可撓式印刷電路板120與150的重量與成本都加倍。而且，這樣總共需要四次的連接製程，不僅製程時間較長，整體良率也會因此下降。Touch panels are often mounted above the display panel. In this way, the user can directly click on the image displayed on the display panel to perform the touch operation. Therefore, the touch panel and the display panel must be connected to the respective driving circuits by a flexible printed circuit board. As shown in FIG. 1 , the display panel 110 is connected to the driving circuit board 130 by the flexible printed circuit board 120 , and the touch panel 140 is connected to the driving circuit board 130 by the flexible printed circuit board 150 . A display surface is disposed on the driving circuit board 130 The driving chip 132 of the board 110 and the driving wafer 134 of the touch panel 140. However, the display panel 110 uses a flexible printed circuit board 120, and the touch panel 140 uses a flexible printed circuit board 150. As a result, the weight and cost of the flexible printed circuit boards 120 and 150 are doubled. Moreover, this requires a total of four connection processes, not only the processing time is longer, but the overall yield is also reduced.
本新型創作提供一種可撓式印刷電路板，可解決習知技術中成本高而良率低的問題。The novel creation provides a flexible printed circuit board that solves the problems of high cost and low yield in the prior art.

圖2是依照本新型創作的一實施例的可撓式印刷電路板 的示意圖。請參照圖2，本新型創作的一實施例的可撓式印刷電路板200具有多個第一接墊210、多個第二接墊220與多個第三接墊230。第一接墊210接合一第一元件310的第一連接埠312，第二接墊220接合一第二元件320的第二連接埠322，第三接墊230接合一第三元件330的第三連接埠332。從上述可知，本實施例的可撓式印刷電路板200提供了三種接墊210、220與230，因此可用於連接三種元件310、320、330。如此一來，只要單一個可撓式印刷電路板200就可取代習知技術的兩個可撓式印刷電路板，不僅成本低廉，也可減輕整個模組的重量，同時還減少了連接製程的次數而縮短製程時間，也能提升組裝良率。2 is a flexible printed circuit board in accordance with an embodiment of the present invention Schematic diagram. Referring to FIG. 2 , the flexible printed circuit board 200 of the embodiment of the present invention has a plurality of first pads 210 , a plurality of second pads 220 , and a plurality of third pads 230 . The first pad 210 is coupled to the first port 312 of the first component 310, the second pad 220 is coupled to the second port 322 of the second component 320, and the third pad 230 is coupled to the third component 330. Connect 埠332. As can be seen from the above, the flexible printed circuit board 200 of the present embodiment provides three types of pads 210, 220 and 230, and thus can be used to connect the three elements 310, 320, 330. In this way, as long as a single flexible printed circuit board 200 can replace the two flexible printed circuit boards of the prior art, the cost is not only low, but also the weight of the entire module can be reduced, and the connection process is also reduced. The number of times and shortening the process time can also improve the assembly yield.
在本實施例中，第一接墊210、第二接墊220與第三接墊230是以一般所稱的金手指的型態為例，亦即其寬度大於可撓式印刷電路板200上的其他線路(未繪示)的寬度，以提升連接的良率。此外，本實施例的第一接墊210與第二接墊220排成同一列。因此，第一接墊210與第二接墊220適合連接排成同一列的第一連接埠312與第二連接埠322。另外，本實施例的可撓式印刷電路板200具有一缺口202。缺口202隔開第一接墊210與第二接墊220。藉由缺口202的設計，可增加第一接墊210與第二接墊220相對之間的移動的自由度，以提高分別與第一連接埠312與第二連接埠322的便利性，同時還可增加該接墊區域可彎折之撓曲能力。再者，本實施例的第一接墊210、第二接墊220與第三接墊230都位於可撓式印刷電路板200的邊緣，如此設計的可撓式印刷 電路板200在製作上較為容易而成本低廉。反之，若將接墊製作在非邊緣處，不僅製作較為困難，後續要與別的元件連接時的難度也較高。此外，可撓式印刷電路板200上也可設置有晶片240與被動元件250，本新型創作不限制其數量。In the present embodiment, the first pad 210, the second pad 220 and the third pad 230 are exemplified by the type of the gold finger generally referred to, that is, the width thereof is larger than that on the flexible printed circuit board 200. The width of other lines (not shown) to increase the yield of the connection. In addition, the first pads 210 and the second pads 220 of the embodiment are arranged in the same column. Therefore, the first pad 210 and the second pad 220 are adapted to connect the first connection port 312 and the second connection port 322 arranged in the same column. In addition, the flexible printed circuit board 200 of the present embodiment has a notch 202. The notch 202 separates the first pad 210 from the second pad 220. By the design of the notch 202, the degree of freedom of movement between the first pad 210 and the second pad 220 can be increased to improve the convenience of the first connection port 312 and the second connection port 322, respectively. The flexing ability of the pad area can be increased. Furthermore, the first pad 210, the second pad 220 and the third pad 230 of the embodiment are located at the edge of the flexible printed circuit board 200, and the flexible printing is designed. The circuit board 200 is relatively easy to manufacture and low in cost. On the other hand, if the pad is made at the non-edge, it is not only difficult to make, but also difficult to connect with other components. In addition, the flexible printed circuit board 200 may also be provided with a wafer 240 and a passive component 250. The novel creation does not limit the number thereof.
圖3是依照本新型創作的一實施例的觸控顯示模組的示意圖。請參照圖3，本新型創作的一實施例的觸控顯示模組50包括一顯示面板310、一觸控面板320、一驅動電路板330以及圖2的可撓式印刷電路板200。換言之，本實施例中是將圖2的第一元件310、第二元件320與第三元件330分別限定為顯示面板310、觸控面板320與驅動電路板330，但圖2的可撓式印刷電路板200也可用於連接其他種類的元件。顯示面板310具有第一連接埠312。觸控面板320疊置於顯示面板310上，且具有第二連接埠322。驅動電路板330具有第三連接埠332。可撓式印刷電路板200的第一接墊210接合顯示面板310的第一連接埠312，第二接墊220接合觸控面板320的第二連接埠322，第三接墊230接合驅動電路板330的第三連接埠332。如此一來，只要單一個可撓式印刷電路板200就可取代習知技術的兩個可撓式印刷電路板，不僅成本低廉，也可減輕整個觸控顯示模組50的重量，同時還減少了連接製程的次數而縮短製程時間，也能提升組裝良率。FIG. 3 is a schematic diagram of a touch display module according to an embodiment of the present invention. Referring to FIG. 3 , the touch display module 50 of the present invention includes a display panel 310 , a touch panel 320 , a driving circuit board 330 , and the flexible printed circuit board 200 of FIG . 2 . In other words, in the embodiment, the first component 310, the second component 320, and the third component 330 of FIG. 2 are respectively defined as the display panel 310, the touch panel 320, and the driving circuit board 330, but the flexible printing of FIG. Circuit board 200 can also be used to connect other types of components. The display panel 310 has a first port 312. The touch panel 320 is stacked on the display panel 310 and has a second port 322. The drive circuit board 330 has a third port 332. The first pad 210 of the flexible printed circuit board 200 engages the first connection port 312 of the display panel 310, the second pad 220 engages the second connection port 322 of the touch panel 320, and the third pad 230 engages the drive circuit board. The third port 330 of 330. In this way, as long as the single flexible printed circuit board 200 can replace the two flexible printed circuit boards of the prior art, the cost of the entire touch display module 50 can be reduced, and the weight of the entire touch display module 50 can be reduced. By shortening the process time by connecting the number of processes, the assembly yield can also be improved.
在本實施例中，上述的顯示面板310為液晶面板。此外，顯示面板310的第一連接埠312與觸控面板320的第二連接埠322可能只是分布有多個接墊的接合區，而驅動電路板330的第三連 接埠332則可能是佔有體積的一個連接器，但本新型創作不侷限於此。舉例而言，顯示面板310的第一連接埠312是指顯示面板310的玻璃基板的邊緣分布有多個接墊的區域，而這些接墊可以異方性導電膠或其他方式接合可撓式印刷電路板200的第一接墊210。觸控面板320的第二連接埠322是指觸控面板320的軟性基板的邊緣分布有多個接墊的區域，而這些接墊可以異方性導電膠或其他方式接合可撓式印刷電路板200的第二接墊220。驅動電路板330的第三連接埠332可以是焊接在驅動電路板330上的連接器，由絕緣本體以及嵌置於絕緣本體內的金屬端子構成。另外，從直視顯示面板310的方向觀看，本實施例的顯示面板310的第一連接埠312與觸控面板320的第二連接埠322的位置是錯開的，因此便於與可撓式印刷電路板200的第一接墊210與第二接墊220接合。In the embodiment, the display panel 310 described above is a liquid crystal panel. In addition, the first connection port 312 of the display panel 310 and the second connection port 322 of the touch panel 320 may be only a joint area in which a plurality of pads are distributed, and the third connection of the drive circuit board 330 The interface 332 may be a connector occupying a volume, but the novel creation is not limited thereto. For example, the first connection port 312 of the display panel 310 refers to a region where a plurality of pads are distributed on the edge of the glass substrate of the display panel 310, and the pads can be flexographically printed by an anisotropic conductive adhesive or other means. The first pad 210 of the circuit board 200. The second connection port 322 of the touch panel 320 refers to a region where a plurality of pads are distributed on the edge of the flexible substrate of the touch panel 320, and the pads may be connected to the flexible printed circuit board by an anisotropic conductive adhesive or other means. The second pad 220 of 200. The third port 332 of the driving circuit board 330 may be a connector soldered to the driving circuit board 330, and is composed of an insulating body and metal terminals embedded in the insulating body. In addition, the position of the first connection port 312 of the display panel 310 of the present embodiment and the second connection port 322 of the touch panel 320 are staggered when viewed from the direction of the direct view display panel 310, thereby facilitating the flexible printed circuit board. The first pads 210 of 200 are joined to the second pads 220.
綜上所述，在本新型創作的可撓式印刷電路板與觸控顯示模組中，可撓式印刷電路板提供了三種接墊。因此，只要使用單一可撓式印刷電路板就可以將觸控面板與顯示面板分別都連接至驅動電路板。如此，省下了一個可撓式印刷電路板的成本與重量，也減少了連接的次數而可縮短製程時間並提昇產品良率。In summary, in the flexible printed circuit board and the touch display module of the present invention, the flexible printed circuit board provides three kinds of pads. Therefore, the touch panel and the display panel can be respectively connected to the driving circuit board by using a single flexible printed circuit board. This saves the cost and weight of a flexible printed circuit board and reduces the number of connections to shorten process time and increase product yield.
