Description
本發明係關於一種行動電子裝置的螢幕控制模組及其觸控面板控制器，尤指一種可擴大體積長寬比以滿足行動電子裝置縮小螢幕邊框寬度需求的螢幕控制模組。 The invention relates to a screen control module of a mobile electronic device and a touch panel controller thereof, in particular to a screen control module capable of expanding a volume aspect ratio to meet the requirement of a mobile electronic device to reduce the width of a screen frame.
由於平板電腦(Tablet Computer)的崛起，使既有電腦市場中各式電腦的市佔比重新洗牌並形成推擠效應，一般認為受平板電腦影響最深的莫過於筆記型電腦(Notebook)。從時尚與科技的角度，平板電腦能夠席捲市場的理由不難想像，但從實用性的角度比較，筆記型電腦仍有平板電腦無法超過的優點與特性。例如平板電腦憑藉優異的觸控介面支援人性化的直覺式操作，但在需要大量輸入文字的場合，即明顯暴露手寫輸入的缺點，因為手寫速度遠遠不及使用鍵盤動輒每分鐘數十字的輸入速度。儘管筆記型電腦在體積、重量及電池待機時間等項目上不如平板電腦，但基於不同的使用目的、用途，筆記型電腦仍保有平板電腦無法完全取代的地位。 Due to the rise of Tablet Computer, the market share of various computers in the existing computer market has been reshuffled and a push effect has been formed. It is generally believed that the most affected by the tablet is the notebook. From the perspective of fashion and technology, the reasons why tablets can sweep the market are not difficult to imagine, but from a practical point of view, notebook computers still have the advantages and features that tablet PCs cannot exceed. For example, a tablet computer supports humanized intuitive operation with an excellent touch interface, but in the case where a large amount of input text is required, the disadvantage of handwriting input is obviously exposed, because the handwriting speed is far less than the input speed of using the keyboard to count the number of crosses per minute. . Although notebooks are not as good as tablets in terms of size, weight, and battery standby time, notebook computers still retain the status that tablets cannot completely replace based on different purposes and uses.
由上述可知，筆記型電腦在市場上依然可以保持一定的優勢，而業者也持續地進行筆記型電腦相關技術的研發與改進。在研發改進的各項技術中，筆記型電腦的螢幕上蓋也是其中一個備受關注的項目，如圖8所示，已知筆記型電腦包括一含有鍵盤71的主機70、一透過樞紐器樞設在主機70一側邊 緣上而內嵌有顯示器73的螢幕上蓋72。請參閱圖9所示，已知的螢幕上蓋72是在相對主機70的內側面上具有一矩形邊框720，該顯示器73設於邊框720內側，而由邊框720定義出顯示器73的有效顯示區域，在此狀況下，邊框720的寬度W即直接影響顯示器73的有效顯示區域大小。儘管如此，螢幕上蓋72的邊框720事實上有其存在的必要性，其主要作用在於顯示器73的固定與防護，更重要的是：用以驅動顯示器73及/或觸控面板(若顯示器73上覆設有觸控面板)的螢幕控制模組也設置在邊框720內。 As can be seen from the above, the notebook computer can still maintain certain advantages in the market, and the industry continues to develop and improve the related technologies of the notebook computer. Among the various technologies developed and improved, the screen cover of the notebook computer is also one of the most concerned items. As shown in FIG. 8, the notebook computer is known to include a host 70 having a keyboard 71 and a pivoting device. On the side of the host 70 A screen upper cover 72 of the display 73 is embedded in the edge. Referring to FIG. 9, the known upper cover 72 has a rectangular frame 720 on the inner side of the main body 70. The display 73 is disposed inside the frame 720, and the effective display area of the display 73 is defined by the frame 720. In this case, the width W of the bezel 720 directly affects the effective display area size of the display 73. However, the frame 720 of the upper cover 72 has the necessity of its existence, and its main function is the fixing and protection of the display 73, and more importantly, the display 73 and/or the touch panel (if the display 73 is used) A screen control module that is covered with a touch panel is also disposed within the bezel 720.
所謂的螢幕控制模組主要是在一電路板80上設有一個以上的控制器81，該控制器81透過電路板80上的線路及連接器82和顯示器73及/或觸控面板電連接。當消費市場有進一步放大顯示器73的有效顯示區域的需求時，則首先必須考慮縮小螢幕上蓋72的邊框720寬度，然而縮小邊框720寬度必須一併考慮的是螢幕控制模組的寬度，惟有在螢幕控制模組寬度可能縮小的情況下，邊框720才可能縮小。 The so-called screen control module is mainly provided with one or more controllers 81 on a circuit board 80. The controller 81 is electrically connected through the lines on the circuit board 80 and the connector 82 and the display 73 and/or the touch panel. When the consumer market has a need to further enlarge the effective display area of the display 73, it is first necessary to consider reducing the width of the bezel 720 of the upper cover 72. However, the width of the reduced frame 720 must be considered together with the width of the screen control module, only on the screen. If the width of the control module may be reduced, the frame 720 may be reduced.
但以既有螢幕控制模組的構成，縮小其寬度確實存在障礙，請參閱圖10所示，前述螢幕控制模組主要係在電路板80上設有一個以上的控制器81、一個以上的連接器82及多個被動元件83，而縮小螢幕控制模組的寬度，首先必須縮小電路板80的寬度，但電路板80能否縮小其寬度，端視其上安裝的元件尺寸，而其上的主要元件為控制器81，但既有控制器81的封裝構造具有相當的寬度，在此狀況下，電路板80寬度勢必要大於控制器81的寬度，始能符合安裝元件的需求。 However, with the configuration of the existing screen control module, there is a real obstacle to narrowing the width. Referring to FIG. 10, the above-mentioned screen control module mainly has more than one controller 81 and more than one connection on the circuit board 80. The device 82 and the plurality of passive components 83, and reducing the width of the screen control module, firstly, the width of the circuit board 80 must be reduced, but whether the circuit board 80 can reduce its width, depending on the component size mounted thereon, The main component is the controller 81, but the package configuration of the controller 81 has a considerable width. In this case, the width of the circuit board 80 must be greater than the width of the controller 81 to meet the requirements of the mounting components.
由上述可知，筆記型電腦市場對於螢幕上蓋的顯示器有效顯示區域有進一步擴大的需求，欲擴大有效顯示區域則必須考慮縮小螢幕上蓋的邊框寬度，而邊框寬度則受內裝螢幕控制模組的寬度所限制，因此欲縮小螢幕上蓋的邊框寬度，必須對縮小螢幕控制模組的寬度提出具體的因應方案。 It can be seen from the above that the notebook computer market has a further requirement for the effective display area of the display on the screen cover. To expand the effective display area, the width of the border of the screen cover must be reduced, and the width of the frame is limited by the width of the built-in screen control module. Because of the limitation, in order to reduce the width of the border of the screen cover, it is necessary to propose a specific solution for reducing the width of the screen control module.
本發明主要目的在提供一種行動電子裝置的螢幕控制模組，主要是在電路板上安裝具特殊比例封裝體的觸控面板控制器，使電路板得以擴大其長度與寬度的比例，從而可以縮小螢幕控制模組的寬度，以消除既有筆記型電腦縮小螢幕上蓋邊框寬度的障礙。 The main purpose of the present invention is to provide a screen control module for a mobile electronic device, which mainly mounts a touch panel controller with a special proportional package on a circuit board, so that the circuit board can expand the ratio of its length to the width, thereby reducing the ratio.

在前述行動電子裝置的螢幕控制模組中，是使該觸控面板控制器的封裝體長度、寬度比例不小於2，在觸控面板控制器的封裝體寬度得以縮小的情況下，螢幕控制模組的電路板寬度自得以對應縮小，從而使螢幕上蓋縮小其邊框以擴大顯示器有效顯示區域的需求成為可能。 In the screen control module of the mobile electronic device, the length and width ratio of the package of the touch panel controller are not less than 2, and the screen control mode of the touch panel controller is reduced, and the screen control mode is reduced. The board width of the group is reduced accordingly, making it possible to reduce the size of the screen cover to enlarge the effective display area of the display.

為達成前述目的採取的技術手段係令前述螢幕控制模組的觸控面板控制器係由一具有封裝體的積體電路所構成，該觸控面板控制器的封裝體的長度與寬度的比值為2至4之間，且該封裝體的長度小於或等於20mm，寬度小於或等於6mm，該封裝體設有複數分別沿長度方向及寬度方向排列的電性觸 點，其沿著該長度方向設置的電性觸點數量大於沿著該寬度方向設置的電性觸點數量。 The technical means for achieving the foregoing objective is that the touch panel controller of the foregoing screen control module is composed of an integrated circuit having a package body, and the ratio of the length to the width of the package of the touch panel controller is Between 2 and 4, and the length of the package is less than or equal to 20 mm, and the width is less than or equal to 6 mm, the package body is provided with a plurality of electrical contacts arranged along the length direction and the width direction respectively. The point that the number of electrical contacts disposed along the length direction is greater than the number of electrical contacts disposed along the width direction.
由於前述控制器的封裝體長度、寬度比例不小於2，其封裝體上的複數電性觸點得以分別在長度方向及寬度方向排列，且沿長度方向設置的電性觸點數量大於沿著寬度方向設置的電性觸點數量，藉此可適用在具有狹長電連接介面的載體上。 Since the package length and width ratio of the controller are not less than 2, the plurality of electrical contacts on the package are respectively arranged in the length direction and the width direction, and the number of electrical contacts disposed along the length direction is greater than the width along the width. The number of electrical contacts arranged in the direction, whereby it can be applied to a carrier having an elongated electrical connection interface.
本發明的另一目的在提供一種行動電子裝置，係包括：一觸控面板；一螢幕上蓋，用以供設置該觸控面板，該螢幕上蓋一側形成有一邊框；及一螢幕控制模組，對應設置於該邊框內，其包含：一電路板，設有複數個焊墊；及一個以上的觸控面板控制器，連接該觸控面板，該觸控面板控制器係由一具有封裝體的積體電路所構成，該封裝體包含複數個電性觸點，該封裝體設置於該電路板之表面，且該電性觸點係對應電性連接該複數個焊墊，其中該觸控面板控制器的封裝體之長度與寬度的比值為2至4之間，且該封裝體的長度小於或等於20mm，寬度小於或等於6mm。 Another object of the present invention is to provide a mobile electronic device, comprising: a touch panel; a screen cover for providing the touch panel, a side of the upper cover of the screen is formed with a frame; and a screen control module, Correspondingly disposed in the frame, comprising: a circuit board having a plurality of solder pads; and one or more touch panel controllers connected to the touch panel, the touch panel controller is provided by a package body The integrated circuit comprises a plurality of electrical contacts, the package is disposed on a surface of the circuit board, and the electrical contact is electrically connected to the plurality of pads, wherein the touch panel The ratio of the length to the width of the package of the controller is between 2 and 4, and the length of the package is less than or equal to 20 mm and the width is less than or equal to 6 mm.
由於該行動電子裝置之螢幕控制模組具有前述之優點；如此一來，該觸控面板控制器的封裝體長度、寬度比例不小於2，在觸控面板控制器的封裝體寬度得以縮小的情況下，螢幕控制模組的電路板寬度自得以對應縮小，從而使螢幕上蓋縮小其邊框以擴大顯示器有效顯示區域的需求成為可能。 The screen control module of the mobile electronic device has the advantages described above; in this case, the length and width ratio of the package of the touch panel controller is not less than 2, and the package width of the touch panel controller is reduced.

The mounting of the connectors 31, 32 and the passive component 33 can be respectively soldered using a plug-in surface. Adhesive (SMT) and other methods, which are known technologies, will not be described again.
前述電路板10係呈狹長狀，其可實現的長度、寬度範圍分別是長度50~80mm，寬度為小於等於9mm。又電路板10表面設有一個以上的狹長狀電連接介面11，用以安裝前述控制器20，該電連接介面11係由複數形成在電路板10表面的焊墊110所組成，該等焊墊110分別沿著一第一方向和一第二方向排列，在本實施例中，所稱第一方向是指電路板10的長度方向，第二方向則指在電路板10上垂直於長度方向的寬度方向，亦即該等焊墊110是呈矩陣排列，而位在長度方向的焊墊110數量大於位在寬度方向上的焊墊110數量，舉例而言，其位在長度方向的焊墊110為20個，位在寬度方向的焊墊110為8個。 The circuit board 10 is elongated and has a length and a width ranging from 50 to 80 mm and a width of 9 mm or less. Further, the surface of the circuit board 10 is provided with one or more elongated electrical connection interfaces 11 for mounting the controller 20, and the electrical connection interface 11 is composed of a plurality of pads 110 formed on the surface of the circuit board 10, the pads 110 is respectively arranged along a first direction and a second direction. In the embodiment, the first direction refers to the length direction of the circuit board 10, and the second direction refers to the length direction of the circuit board 10 perpendicular to the length direction. In the width direction, that is, the pads 110 are arranged in a matrix, and the number of pads 110 in the length direction is larger than the number of pads 110 in the width direction, for example, the pads 110 in the length direction. There are 20, and the number of pads 110 in the width direction is eight.
請配合參閱圖2所示，該控制器20係由積體電路構成而具有一封裝體200，該封裝體200具有一長度L及一寬度W，其長度L大於寬度W，且長度與寬度的比例不小於2，可以實現的比例範圍為2~4，可以實現的封裝體200尺寸分別為：長度不大於20mm，優選為10~13mm，寬度則小於等於6mm。因而所稱的封裝體200是呈狹長狀，而封裝體20底面設有不少於100個的複數電性觸點210，該等電性觸點210分別沿著該封裝體200之長度方向和寬度方向排列，且該封裝體200的長度方向與前述第一方向相對應，該封裝體200上垂直於長度方向的寬度方向則與該第二方向相對應，亦即該等電性觸點210是呈矩陣排列，而位在長度方向的電性觸點210數量大於位在寬度方向上的電性觸點210數量，其排列方式與位置與電路板10上的各個焊墊110匹配，因此可對應電連接。 Referring to FIG. 2, the controller 20 is composed of an integrated circuit and has a package body 200 having a length L and a width W, the length L being greater than the width W, and the length and the width. The ratio is not less than 2, and the ratio that can be achieved ranges from 2 to 4. The dimensions of the package 200 that can be achieved are: length not greater than 20 mm, preferably 10 to 13 mm, and width less than or equal to 6 mm. Therefore, the package body 200 is formed in a narrow shape, and the bottom surface of the package body 20 is provided with not less than 100 plurality of electrical contacts 210, respectively, along the length direction of the package body 200. Arranging in the width direction, and the length direction of the package body 200 corresponds to the first direction, and the width direction perpendicular to the length direction of the package body 200 corresponds to the second direction, that is, the electrical contacts 210 The number of the electrical contacts 210 in the length direction is greater than the number of the electrical contacts 210 in the width direction, and the arrangement and position are matched with the respective pads 110 on the circuit board 10, so Corresponding to electrical connection.
以下例舉數種封裝體200可行的長度、寬度比例及對應的電性觸點210數量：
前述控制器20的封裝體200所設電性觸點210形式視其採用的封裝技術而有不同，在本實施例中，該控制器20是一球格陣列(BGA)元件，因此封裝體200上的電性觸點210係由錫球構成；另外，當控制器20是一晶片尺寸封裝(CSP)元件或一晶圓級晶片尺寸封裝(WLCSP)元件時，封裝體200上的電性觸點210依然係由錫球構成。若控制器20是一無錫球的觸點陣列(LGA)元件時，則封裝體200上的電性觸點210是由其底面的焊墊所構成。 The form of the electrical contact 210 of the package 200 of the controller 20 is different depending on the packaging technology used. In the embodiment, the controller 20 is a ball grid array (BGA) component, and thus the package 200 The upper electrical contact 210 is composed of solder balls; in addition, when the controller 20 is a chip size package (CSP) component or a wafer level wafer size package (WLCSP) component, the electrical contact on the package 200 Point 210 is still composed of solder balls. If the controller 20 is a contactless array (LGA) component of a solderless ball, the electrical contact 210 on the package 200 is formed by a solder pad on the bottom surface thereof.
由上述可知，本發明的螢幕控制模組是使電路板10上的複數焊墊110分別沿第一方向及第二方向排列，並使沿著第一方向設置的焊墊110數量大於沿著第二方向設置的焊墊110數量，以構成一狹長的電連接介面11，以便與具有複數電性觸點210且作相同形式排列的控制器20對應連接；在前述匹配關係下，該控制器20的封裝體200得以擴大其長度L與寬度W的比例，在長度L拉長而寬度W縮小的狀況下，控制器20可以縮小與電路板10的相對寬度比(寬度對寬度)(如圖2所示)，因此電路板10的寬度與螢幕控制模組的整體寬度均得以縮小，藉此可以消除縮小螢幕上蓋的邊框寬度但受限於螢幕控制模組的限制因素。因此如圖3、圖4所示，當螢幕控制模組安裝筆記型電腦60的螢幕上蓋61內，該螢幕上蓋61的邊框610寬度W1即得以縮小，從而擴大顯示器的有效顯示區域。 As can be seen from the above, the screen control module of the present invention is such that the plurality of pads 110 on the circuit board 10 are arranged in the first direction and the second direction, respectively, and the number of pads 110 disposed along the first direction is greater than The number of the pads 110 disposed in the two directions is configured to form a long and narrow electrical connection interface 11 for correspondingly connecting with the controller 20 having the plurality of electrical contacts 210 and arranged in the same form; in the foregoing matching relationship, the controller 20 The package 200 is enlarged in proportion to its length L and width W. In the case where the length L is elongated and the width W is reduced, the controller 20 can reduce the relative width ratio (width to width) to the board 10 (see FIG. 2). As shown, the width of the board 10 and the overall width of the screen control module are reduced, thereby eliminating the limitation of reducing the width of the border of the screen cover but limited by the screen control module. Therefore, as shown in FIG. 3 and FIG. 4, when the screen control module is mounted on the screen upper cover 61 of the notebook computer 60, the width W1 of the frame 610 of the screen upper cover 61 is reduced, thereby expanding the effective display area of the display.
由前述實施例可知，本發明係拉長控制器20的封裝體200的長寬比，以降低其與電路板10間的相對寬度比。為確保控制器20在安裝(例如回焊)時不致發生撓曲(warp)現象，本發明進一步提出以下技術方案，以因應可能的撓曲的問題：其中一個技術方案是令前述控制器20採用晶圓級晶片尺寸封裝(WLCSP)元件，請參閱圖5，其揭示一晶圓級晶片尺寸封裝元件，主要係在一矽基材40的一表面上裝設有一晶片41，晶片41周圍設有一防護膠層42，又晶片41表面植設有複數凸塊(pad)43，該晶片41與防護膠層42上層又覆設有一介電層44，該介電層44具有內層線路440，且在表面植設有錫球45，各錫球45係透過介電層44的內層線路440與晶片41上的凸塊43電連接。 As can be seen from the foregoing embodiments, the present invention lengthens the aspect ratio of the package 200 of the controller 20 to reduce the relative width ratio between the package and the board 10. In order to ensure that the controller 20 does not undergo a warp phenomenon during installation (for example, reflow), the present invention further proposes the following technical solutions to cope with possible flexing problems: one of the technical solutions is to adopt the aforementioned controller 20 Wafer Level Wafer Size Package (WLCSP) component, please refer to FIG. 5, which discloses a wafer level wafer size package component, mainly comprising a wafer 41 mounted on a surface of a substrate 40, and a wafer 41 is disposed around the wafer 41. The protective layer 42 and the surface of the wafer 41 are implanted with a plurality of pads 43. The upper layer of the wafer 41 and the protective layer 42 are further covered with a dielectric layer 44 having an inner layer 440. Solder balls 45 are implanted on the surface, and each of the solder balls 45 is electrically connected to the bumps 43 on the wafer 41 through the inner layer wiring 440 of the dielectric layer 44.
如前揭所述的晶圓級晶片尺寸封裝元件因在晶圓製程中完成，其晶片41與矽基材40均為矽晶材料，因此其接合面的熱浪係數小，可有效降低回焊時的熱對元件產生的撓曲效應。 The wafer-level chip-scale package component as described above is completed in the wafer process, and the wafer 41 and the germanium substrate 40 are both twinned materials, so the heat wave coefficient of the joint surface is small, which can effectively reduce the reflow time. The deflection effect of the heat on the component.
本發明採用的另一技術手段係採用CCL基材作為封裝載板，利用CCL基板的抗撓曲能力因應回焊時對封裝載板的撓曲效應。請參閱圖6A所示，係一典型的晶片尺寸(CSP)元件，主要係在一封裝載板50的表面設有一晶片51，該封裝載板50具有內層線路，且表面形成多數凸塊54，其底面植設有多數錫球52，該凸塊54與錫球52係透過內層線路相互連接；該晶片51表面設有焊墊，透過打線方式與封裝載板50表面的凸塊54電連接，而後在封裝載板50與晶片51外形成一封膠層53以完成封裝。 Another technical method adopted by the present invention uses a CCL substrate as a package carrier, and utilizes the flexural resistance of the CCL substrate in response to the deflection effect on the package carrier during reflow. Referring to FIG. 6A, a typical chip size (CSP) component is mainly provided on the surface of a loading board 50 with a wafer 51 having an inner layer line and a plurality of bumps 54 formed on the surface. A plurality of solder balls 52 are implanted on the bottom surface thereof, and the bumps 54 and the solder balls 52 are connected to each other through the inner layer line; the surface of the wafer 51 is provided with a solder pad, and the bumps 54 on the surface of the package carrier 50 are electrically connected. The connection is followed by forming a glue layer 53 on the package carrier 50 and the wafer 51 to complete the package.
又如圖6B所示，則係一採用覆晶(FC)技術的晶片尺寸(CSP)元件，主要係在一封裝載板50的表面以覆晶(FC)植設有一晶片51，該封裝載板50具有內層線路，且表面形成多數凸塊54，其底面植設有多數錫球52，該凸塊54與錫球52係透過內層線路相互連接；該晶片51表面植設有錫球55，透過覆晶方 式與封裝載板50表面的凸塊54電連接，而後在封裝載板50與晶片51外形成一封膠層53以完成封裝。 As shown in FIG. 6B, a wafer size (CSP) device using flip chip (FC) technology is mainly provided on a surface of a loading board 50 to form a wafer 51 on a flip chip (FC). The plate 50 has an inner layer line, and a plurality of bumps 54 are formed on the surface, and a plurality of solder balls 52 are implanted on the bottom surface thereof. The bumps 54 and the solder balls 52 are connected to each other through the inner layer line; the wafer 51 is coated with solder balls on the surface thereof. 55, through the surface of the crystal The bumps 54 are electrically connected to the surface of the package carrier 50, and then a glue layer 53 is formed on the package carrier 50 and the wafer 51 to complete the package.
當前述封裝載板50由CCL基板構成時，其構造係如圖7所示，主要係由多層介電層501與多層銅線路層502交疊構成一多層基板，其中每一介電層501,501A內分別設有一層玻纖布503。而為提升多層基板的抗撓強度，本發明係可降低至少一介電層501A內的玻纖布503厚度，但增加該介電層501A內的玻纖布層數，亦即在該介電層501A內設有二層以上的玻纖布503，例如當介電層501A厚度為015mm時，原配置厚度為0.14mm(料號1056)的玻纖布503，則可降低玻纖布503的厚度至0.05mm(料號1086)，並增加其層數。當介電層501A厚度為0.25mm時，原配置2層厚度為0.09mm(料號2116)的玻纖布503，則可將玻纖布503的厚度降低至0.08mm(料號3313)，並增加其層數。 When the package carrier 50 is composed of a CCL substrate, the structure is as shown in FIG. 7 , and the multi-layer dielectric layer 501 and the plurality of copper circuit layers 502 are overlapped to form a multi-layer substrate, wherein each dielectric layer 501, 501 A fiberglass cloth 503 is provided in each of A. In order to improve the flexural strength of the multilayer substrate, the present invention can reduce the thickness of the fiberglass cloth 503 in at least one dielectric layer 501A, but increase the number of fiberglass layers in the dielectric layer 501A, that is, in the dielectric. Two or more layers of fiberglass cloth 503 are disposed in the layer 501A. For example, when the thickness of the dielectric layer 501A is 015 mm, the original fiberglass cloth 503 having a thickness of 0.14 mm (item number 1056) can reduce the fiberglass cloth 503. Thickness to 0.05mm (item 1086) and increase the number of layers. When the thickness of the dielectric layer 501A is 0.25 mm, the original thickness of the fiberglass cloth 503 having a thickness of 0.09 mm (item 2116) can reduce the thickness of the fiberglass cloth 503 to 0.08 mm (item number 3313). Increase the number of layers.
一般CCL基板在介電層501,501A內設置玻纖布503，原本即具有相當的抗撓曲能力，本發明在原有厚度的介電層501A內增加玻纖布503層數，則可進一步提升抗撓曲強度。 Generally, the CCL substrate is provided with a fiberglass cloth 503 in the dielectric layer 501, 501A, which has a considerable resistance to deflection. The invention increases the number of layers of the fiberglass cloth 503 in the dielectric layer 501A of the original thickness, thereby further enhancing the resistance. Flexural strength.
由上述可知，本發明的螢幕控制模組是在電路板上設以分別沿第一方向及第二方向排列的複數焊墊，並使沿著第一方向設置的焊墊數量大於沿著第二方向設置的焊墊數量，以構成一狹長的電連接介面；又配合一控制器在其狹長狀封裝體上設以相同排列方式的複數電性觸點，以對應連接；在前述設計下，該控制器的封裝體得以擴大其長度與寬度的比例，在長度拉長而寬度縮小的狀況下，控制器可以縮小與電路板的相對寬度比，因此電路板的寬度得以縮小，從而螢幕控制模組的整體寬度亦可隨之縮小，藉以滿足縮小螢幕上蓋的邊框寬度的需求。 As can be seen from the above, the screen control module of the present invention is provided with a plurality of pads arranged on the circuit board in the first direction and the second direction, respectively, and the number of pads disposed along the first direction is greater than that along the second The number of pads disposed in the direction to form a long and narrow electrical connection interface; and a controller is provided with a plurality of electrical contacts in the same arrangement on the elongated package for corresponding connection; under the foregoing design, The controller package can expand its length to width ratio. Under the condition that the length is elongated and the width is reduced, the controller can reduce the relative width ratio of the board, so the width of the board can be reduced, so that the screen control module The overall width can also be reduced to meet the need to reduce the width of the border of the screen cover.
