New Description: [New Technology Field] This creation is about a membrane keyboard, especially for a light-emitting membrane keyboard and its backlight module. [Prior Art] With the rapid development of technology, the main development trend of today's technology products lies in the convenience of carrying and use. Therefore, how to achieve light, thin, short and small focus on current R&D design, but on the current personal electronic products. The overall size of the design and the above-mentioned size is too large, which is not in line with the current main demand is that it is convenient to carry, so it is quite inconvenient. As a result, the keyboards currently available on the market are broadly classified into hard keyboards, foldable keyboards, and thin-mode keyboards. The so-called hard keyboard refers to a general computer keyboard or a notebook computer type key, which generally comprises an upper and lower case ^, a circuit board located inside the upper and lower housings, a rubber button and a key cap, etc. It's too big and cumbersome, and it doesn't have the folding function and can't be used as a personal mobile communication product. In order to meet the needs of portability, some manufacturers have developed a multi-segment folding and reaching (4) portable keyboard structure, which is defined on the base by the appropriate spacing of the arrangement position of the complex array, in the assembly area i ^- The circuit board made of the bendable material f and the complex digital chi, and fixed under the 座^座--a substrate made of f-fold material and on the board: a protective frame with a concave-convex connection at the periphery, #板之plate. However, the upper...m structure can be used to facilitate the folding of the keys ^, σ can be small, but the thickness after folding is thicker than a 3 M4U5594 keyboard, which is not easy for the user to carry in the bag. Moreover, after the keyboard is unfolded, there is no support or mechanism for the bottom and the periphery of the keyboard to provide mechanical support for the fold of the keyboard f. Therefore, when the keyboard is in use, the tube fold is easily loosened or deformed to form a height. The drop causes the user to operate or press the button. In order to improve the above disadvantages, a kind of flexible membrane keyboard is produced. The substrates and circuit boards of the above-mentioned membrane keyboard are made of soft materials, in particular, a flexifiable type is used. material,
因此’使用者可直接彎折或捲曲此薄膜鍵盤，由於薄膜鍵 盤之厚度非常薄’故f折或捲曲後之厚度較—般可折收式 鍵盤更低，且由於其係利用材料特性進行折收及展開，而 非利用機械結構，故當其展開時，不會產生鬆動或變形之 現象’當然更不會造成習知可折收鍵盤的高低差問題，進 而便於制者操作及搞帶。此外，為了提供使用者在黑暗 或是光線不足的環境下操作薄膜鍵盤，遂發展出—種發光 式涛膜鍵盤，其係將背光模組設置於薄膜鍵盤中，以達到 發光的功效。 具體而言，薄骐鍵盤之背光模組係採用貼片式發光二 極體（LED)作為光源，其係貼負於薄膜鍵盤架構之側邊， 以提供側向光線，並由導光膜（Light Guide FUm，LGF) 將側發光式發光二極體的光線均勻分佈在整個導光膜内， 而導光膜可利用分佈於其表面的導光點將側光線垂直導出 導光膜’然後’ f出的光線會穿透過可撓曲式薄膜開關 (MemBrane )，進而照亮鍵帽（Key τ〇ρ )上的字母圖案， 4 M405594 • t 藉此，使用者即可在黑暗或光線不足的環境下輕鬆地操作 薄膜鍵盤。 在客兵的《光薄膜鍵盤令，其可挽曲式薄膜開關具有 上下兩基體，而在上述兩基體上分別印刷有上、下兩導通 點，並相向設置，當使用者按壓按鍵時，會帶動上基體往 下基體移動’使得上導通點碰觸τ導通點，造成電性搞合， 進而提供按鍵的輸入訊號給控制震置（如：電腦）。然而， 在習知技術中’上述導通點均為非透明的實心圓點，其係 統的銀材料所構成，而此類導通點會遮蔽導光膜之部 =光點所引導出來的光線，因而在導通點處產生嚴重的 遽先現象’俾使由導光膜所穿透的光通量大幅減少，進而 &紐光薄膜鍵盤之光線不均勻，而不便於使用者操作。 絲上所述，在習知的發光薄膜鍵盤中，仍存在—些困 難及缺點以待克服。 一 【新型内容】 為了克服上述困難及缺赴 , k田雞及缺點，本創作提供一種薄膜鍵 ‘，特別係關於一種發光@# 、 ㈣姐请s 種鍵盤及其背光模組，其係利 用透明導通點取代習知的導通 μ &丄 V通2 目的在於消除習知薄膜 鍵盤中光線的遮蔽點，藉增 、 ^ ^ , 稚乂曰加可穿透導光膜之光通量， 進而k升發光薄膜鍵盤之光線均勻度。 為了達到上述目的，本創作趄 模組，其包含：一導光膜共一種涛膜鍵盤之背光 膜數導光點，且上述導光 膜上玟置至少一透明下導通點 導-χ,Λ ^ 透明膠層，附著於上述 式薄膜開關’附著於上述透明膠層之對 5 應上述導光臈之另一表面，上 上導通 =:發光二極體’設置於上述導光膜之側邊，藉 八方本創作更進-步提供—㈣膜鍵盤，其包 • μ u ,、— 舞11體，至少一鍵帽，覆蓋於 -有二、二二刀腳及上述至少一彈性體；-背光模組，具 I ‘北 么、上述至夕一男刀腳對應插入。复中，上 =模組包含:一導光膜，具有複數導光點，且：述導光 導置ΐί —透明下導通點；一透明膠層’附著於上述 應上述導關，附著於上述透明膠層之對 少-透明上遵、£ ♦ 上述可挽曲式薄膜開關具有至 n用以對應接觸上述至少—透明下導通 .·，占’及至V —發光二極體， 以提供光線。 ㉟叹置於上述導光膜之側邊，藉 有機導電構之上下導通點均為透明，其可由 他組件亦為透明，故，於本創作之背光模 自由通過，!何會阻礙光線之組件，因此可允許光線 亮度。 心升湾膜鍵盤的發光均勻度，並增加整體 術手^上所述係用以_本創作之目的、達成此目的之技 ΪΓ二:及其產生的優點等等。而本創作可從以下較:ΐ 教述並伴隨後附圖式及申請專利範圍使讀者得以 6 M405594 更加清楚了解。 【貫施方式】 ，創作將以較佳實施例及觀點加以敘述，此類欽述係 =釋本^之結構及步驟，€用以說明而非用以限制本創 之申請專利範圍。因此，除說明書甲之較佳實施例以外， 創作亦可廣泛實行於其他實施例中。 本創作提供一種發光薄膜鍵盤及其背光模組，其改良 在於、β光杈組之導通點係呈現透明狀，以取代習知技術 的不透明導通點’藉此克服過去發光薄膜鍵盤中，因導通 點光性所導致亮度下降及發光不均勾的問題。 請參閱圖一所示，圖一係顯示本創作所揭露之薄膜鍵 盤之較佳實施例’包含：複數鍵帽1〇1、複數剪刀腳⑽、 一可撓曲式薄膜開關103、一透明膠層1〇4、複數發光二極 體（LED) 1G5、複數導光點1Q6、複數透明上導通點⑺7、 複數透明下導通點108、一基底1〇9、_導光膜ιι〇、一基 板111、及複數彈性體112。其中，彈性體112較佳為橡膠。 本實施例係以具有兩個按鍵之鍵盤做為示例，亦即分別有 兩個鍵帽UH、兩個彈性體U2及兩支剪刀腳1〇2，惟，本 領域之技藝者應可知悉上述按鍵數量僅係用以說明，而非 限制本創作’其數量可依據需求而定。於本實施例中，可 撓曲式薄膜開關103、透明膠層i 04、發光二極體丨〇5、導 光點106、透明上導通點107、透明下導通點1〇8、基底1〇9、 及導光膜110之組合，即可謂本創作所揭露之背光模組^ 其令，可撓曲式薄膜開關103包含基底1〇9及複數透明上 7 M405594 .導通點107，且争句人— 示4M …更一片線路及一下片線路（未於圖中 )’上述線路係由非透明銀材料所構' 騎料。其中，透明上導通點107及？成下交為《油 二刷、噴塗、移印、旋塗，、_= = ^曲式薄膜開關103之基底1〇9上。而導光膜丨下 一其係由細小微粒所構成，可: it 表面凹凸不平’故可用以將發光二極體H)5 =的側向光線轉為向上投射之光線，以增加垂直導光 。面二Γ膠層104係附著於可撓曲式薄臈開關⑼ 、面之邊輕域，及導光膜11G上表面之邊緣區域，用 以黏合透明_開_ 1G3及導絲UG。 二係附著於導域η。之上表面，進-步而言，= 導二];=、移印、旋塗、濺鑛 '或蒸鑛等方式附著至 ¥先臈110上，錯以對應接觸透明上導通點1〇 接觸時電性搞合’進而產生一輸入訊號。發光二極體⑺5 係設置於本創作之側邊，以做為本創作之光源。 其中’透明上導通點1〇7及透明下導通點⑽係由 明導電材料所形成’藉以克服遮光問題，進而提供薄膜鍵 盤更佳的發光均勻度及亮度。具體而言，上述透明導 料可包含有機導電油墨，如：PED〇T:pss，其為_種可導 電之高分子材料；亦可包含無機透明金屬導電材料，例如： 氧化銦錫（Indium Tin 0xide，IT〇)、氧化鋅銘⑷⑽ Z1nc oxide, AZO)、氧化鋅（Zn〇)或其他透明金屬氧化物。 而此透明上導通點1〇7及透明下導通點1〇8之形狀可包 8 M405594 :，但不揭限於，圓形、三角形、正方形、多邊形、直線、 曲線種幾何圖形，而較㈣為圓或線，上述的圓形 =佳為實心圓’藉以提供較完整的接觸面積，俾使透明 導通點107於按壓透明下導通點】〇8時，較不易產生誤 差。 、 可撓曲式薄膜開關103及導光臈11〇均具有複數位置 相同之孔洞，用以提供剪刀_ 1G2對應插人，而基板⑴ ㈣以支撐穿過上述孔洞之剪刀腳1〇2，其較佳為紹板。 鍵，101係覆蓋於剪刀腳1〇2及彈性體U2上，其上方印 刷著各種文字、符遽或圖案，以提供使用者按壓。當使用 者施力於鍵帽10"夺’會撐開剪刀腳102，同時使得彈性 體112帶動可撓曲式薄膜開關103之基才反1〇9往下方移 動’進而使得透明上導通點107往下移動，而當透明上導 通點107移動至接觸透明下導通點1〇8日夺，則會電性耦合， 而產生輸入訊號，從而完成按鍵的輸入動作。 另外可參閱圖二所示，本圖為本創作薄膜鍵盤之按鍵 立體組合圖，其包含：鍵帽10卜剪刀腳102、可撓曲式薄 膜開關103、發光二極體（LED)1〇5、導光膜ιι〇、基板⑴、 彈性體！12、凸耳2G1、及槽部2()2。其中，可撓曲式薄膜 開關103包含透明下導通點，設置於下表面（於本圖中未示 出可參閱圖）’而導光膜11〇之表面設有透明上導通點 及導光點(於本圖令未示出，可參閱圖一）’用以增加導光 膜U〇之光通$。凸耳201及槽部202係設置於基板U1 上，用以於組合時分別對應結合剪刀腳102之下端，從而 9 M405594 ^ . 112彈性體 201凸耳 202槽部Therefore, the user can directly bend or curl the membrane keyboard. Since the thickness of the membrane keyboard is very thin, the thickness after folding or crimping is lower than that of the general foldable keyboard, and because the material is folded by the material characteristics. It is not a mechanical structure, so when it is unfolded, it will not cause looseness or deformation. Of course, it will not cause the problem of the height difference of the conventional foldable keyboard, which is convenient for the manufacturer to operate and engage. In addition, in order to provide the user to operate the membrane keyboard in a dark or under-light environment, a light-emitting membrane keyboard has been developed, which is to set the backlight module in the membrane keyboard to achieve the luminous effect. Specifically, the backlight module of the thin keyboard uses a chip-type light-emitting diode (LED) as a light source, which is attached to the side of the membrane keyboard structure to provide lateral light and is guided by a light guiding film ( Light Guide FUm, LGF) uniformly distributes the light of the side-emitting light-emitting diodes throughout the light-guiding film, and the light-guiding film can vertically guide the side light rays to the light guide film by using the light-guiding points distributed on the surface thereof. The light will pass through the flexible membrane switch (MemBrane), which in turn illuminates the letter pattern on the keycap (Key τ〇ρ), 4 M405594 • t, whereby the user can be in a dark or poorly lit environment Easily operate the membrane keyboard. In the passenger's "light film keyboard, the flexible film switch has two upper and lower substrates, and the upper and lower conduction points are respectively printed on the two substrates, and are oppositely arranged, when the user presses the button, Driving the upper substrate to move to the lower substrate, so that the upper conduction point touches the τ conduction point, causing electrical connection, and then providing an input signal of the button to control the vibration (such as a computer). However, in the prior art, the above-mentioned conduction points are all non-transparent solid dots, which are composed of the silver material of the system, and such conduction points shield the light guiding film = the light guided by the light spot, thus A serious phenomenon occurs at the conduction point', so that the light flux penetrated by the light guiding film is greatly reduced, and the light of the & neon film keyboard is uneven, which is not convenient for the user to operate. As described above, in conventional light-emitting membrane keyboards, there are still some difficulties and disadvantages to be overcome. A [new content] In order to overcome the above difficulties and shortcomings, k Tianji and its shortcomings, this creation provides a membrane key', especially for a kind of illuminating @#, (4) sister s keyboard and its backlight module, which is transparent The conduction point replaces the conventional conduction μ & 丄V through 2 to eliminate the shading point of the light in the conventional membrane keyboard, by adding, ^ ^ , the nucleus and the light flux that can penetrate the light guiding film, and then the k illuminating The uniformity of light on the membrane keyboard. In order to achieve the above object, the present invention comprises: a light guiding film, a backlight film number guiding point of a keyboard keyboard, and at least one transparent lower conducting point guide-χ on the light guiding film, Λ ^ a transparent adhesive layer attached to the above-mentioned type of membrane switch 'attached to the pair of transparent adhesive layers 5 on the other surface of the above-mentioned light guide pupil, upper conduction =: light-emitting diode ' is disposed on the side of the light guide film By means of the creation of the eight-party creation, step by step - (4) membrane keyboard, its package • μ u ,, - dance 11 body, at least one keycap, covering - with two or two knife feet and at least one elastic body; The backlight module has I's North, and the above-mentioned eve is inserted into the male and female feet. In the middle, the upper=module comprises: a light guiding film having a plurality of light guiding points, and: the light guiding guide is disposed ΐ ί—the transparent lower conductive point; a transparent adhesive layer is attached to the above-mentioned guide and attached to the transparent The pair of layers is transparent - transparent. ♦ The above-mentioned buckable membrane switch has n to correspondingly contact the at least - transparent lower conduction, and the 'to V' light emitting diode to provide light. 35 sighs on the side of the light guiding film, and the conduction point above the organic conductive structure is transparent, and the component can be transparent. Therefore, the backlight mold of the present invention is free to pass, and why the component of the light is hindered Therefore, the brightness of the light can be allowed. The uniformity of the illumination of the Xinshengwan membrane keyboard, and the increase in the overall skill of the hand is used for the purpose of this creation, the technology to achieve this goal: and its advantages and so on. This creation can be seen from the following: 教 Teaching and accompanying the following figures and the scope of patent application to make the readers more aware of 6 M405594.
