二==，由於傳統式行動電話或是行動電話的背 發射器之侷限光發射區域所提供，所以無 鍵盤上各按輕體區域充足與相同的光，因而存在 热去有效地分辨各按鍵的問題。 於是為了提供充足的背光因而必須設數個光發 =器，進而導致電力過度絲，所以存在有電池使用壽命 鈿短的問題。除此之外，由於必須提供多數個光發射器， 因此亦存在有製造過程及結構變得複雜、設必 15固以及製造費用增加等問題。 、 、為了改良此類問題，係透過在該圓頂開關構造的頂侧 以及該鍵盤非凸出部分之底侧形成一反射薄膜以及一光學 4膜，以減少發光二極體元件。自發光二極體元件發射出 的光係被收集與集中在該鍵盤處，藉此，該鍵盤即能夠以 20少量的發光二極體元件而發射出高效能的光。 第二圖係為一習知應用圓頂開關總成技術之行動電話 的剖面圖，顯示行動電話之背光狀態。 如弟二圖所示’一圓頂開關總成10係黏附於一印刷電 路板30。一具有發光二極體的光發射器32係設置於該印刷 6 200901743 電路板30上。當使用該圓頂狀開關總成10時，由於薄膜 16的反射效應或是散射效應，因此可減少該光發射器32 的設置數目。此外，縱使該光發射器32的設置位置被限定 在該印刷電路板30的中心處，該光發射器32依然能夠提 5 供充足的背光效應。 詳而言之，黏附於該印刷電路板30上之該圓頂開關總 成10係有規律地設置於一鍵盤40之下方。如此一來，該 圓頂開關總成10之各圓頂開關20可與各按鍵42之突出44 接觸，或是可透過各按鍵42之突出加壓於該圓頂狀開關總 1〇成10之各圓頂狀開關20;其中，各按鍵42係裝配於該^ 盤40上與各圓頂狀開關20相對應處。 依據此種配置，由於光學反射或光學散射的作用，自 設置於該印刷電路板30上之各光發射器32所發射出的 光，係被反射或散射進入該圓頂開關總成1〇與該鍵盤4〇 β之間的整個空間，以及藉由各可透光按鍵42而散發至外 部，因此使用者可清楚地分辨各按鍵進而操作之。亦即， 當使用者打開行動電話的上蓋或是按押按鍵使用行動電話 時，電力被提供至設置於該印刷電路板3()上之各光發射哭 32，以致於在以三度空間基礎下所發射出的光之中，部分 2〇發射到該鍵Μ 40的光係被提供至該鍵盤4〇上的各個按鍵 42=而部分剩餘的光則被反射至一用於該鍵盤4〇之底面的 =缚膜50。該反射後的光係面向該圓期_成1〇之薄 以及Ϊ反射後的光係再次被反射至該鍵盤4Q之反射 _ 50，以提供光至其他鄰近的按鍵42。自該光發射器％ 7 200901743 所發射出的光係透過分別設於該圓頂開關總成10以及該鍵 盤40之該薄膜16以及該反射薄膜50，而在該圓頂開關總 成10與該鍵盤40間連續且重複地反射及散射，因此可提 供用於该鍵盤40之各該按鍵42相同亮度的光。這是間接 5照明方法，其係利用光的散射，使自該光發射器所發射出 的光碰撞該上板件的薄膜後而被反射。 第四圖係為第三圖所示習知用於行動電話的按鍵裝置 的平面圖。如第四圖所示，發光二極體光發射器32透過間 接照明方法發射用於鍵盤4〇的光於各按鍵42之間。關於 ίο利用光散射之間接照明方法，係具有如下之缺失：當透過 在該圓頂開關總成之頂側與該鍵盤之底側形成反射薄膜以 提面光照效率時，對應於該數字鍵盤之該等發光二極體元 件的數量並無法大幅度地相對減少，且其形成、安裝以及 設置仍然繁雜。 15 亦即，此種裝置與方法同樣需要多數的發光二極體、 將該發光二極體晶片設置於該印刷電路板的過程複雜，以 及形成該反射薄膜的過程也同樣複雜。因此，如何獲得成 本低廉的置產製程仍然存在許多問題。除此之外，原料的 加工費用以及製造成本也十分昂貴，例如該鍵盤的按鍵， 2〇亦即’該按钮必須透過模塑成形而得。 【發明内容】 【所欲解決的問題】 因此，本發明之一目的在於至少解決習知技術之問題 8 200901743 或是缺失。本發明之目的在於提供一種使用墨水印刷及側 發光方法提供高品質之電子產品的按鍵裝置及其製造方 法。其中’鍵盤之按鍵按紐部分能夠容易地被製造，且高 效月匕之鍵a的按紐部分能夠搭配少量的發光二極體元件， 5而透過使用墨水印刷方法以形成圖案之該纏的製造方 則可提仏同°〇質之產品，且其製造成本低廉以及原料 費用便宜，因此具有節省成本的功效。 【技術手段】 為達成刖述之目的，本發明之一方面係提供一種使用 墨水印刷及側發光方法之電子產品按鍵裝置，其包括一下 板件’係整合有—具有多數圓頂結構之接觸訊號感測單 70，至；-光發射器構裝’其具有一裝設於該下板件之側 面-預定區。域之光源，以產生光；以及一上板件，係整合 有按鈕單凡，用以碰觸與其對應之該接觸訊號感測單 15 其巾，虹板件為—導光板，係將該光發射器構裝所 生的光轉換為—表面光源；該導光板之一側面係經墨水 Ρ刷與烘形成—圖案，域導綠具有—觸動器，其 /、有凹八態樣’係形成於與該接觸訊號感測器單元相對 應的位置’且於其中模塑有紫外線硬化型環氧樹脂。 2〇 、,依據本發明，該導光板之圖案印刷較佳為藉由印刷該 導光板的整個表面或是僅印刷該導光板之一特定區域 成。 该導光板的圖案主要是透過在靠近該光源之發射點位 置處，設計間隔較寬的圖案或是降低圖案的密度，以降低 9 200901743 =入表_量’而在遠離該杨之發射點 計間隔較緊密的圖案或是提高圖案的密度。吟’則設 烘烤該上板件的過程，包括在溫度 度的烤箱中烘烤，並在室溫下自然地硬化。攝氏β度至 其中，該導光板的材料為聚碳酸酯。 其中，該光發射器構裝能夠發射出一種 光。 裡4夕種顏色的 右使用厚度為〇_4毫米之光發射器構裝，該 度為大於或等於0.1毫米，小於〇.2毫米。 板的厚 若使用厚度為0.6亳米之光發射器構裝 度為大於或等於0.2絲，小於G·4絲。^桃的厚 产為G.8毫求之光發射器構裝，該導光板的厚 度為大於或4於0.4亳米，小於0 5毫米。 15 本發明之另-目的係提供—種❹墨水印刷及侧發光 之電子產品按鍵裝置的製造方法’該製造方法包含有下 3 :形成-下板件’該下板件係整合有—具圓頂結構之 接觸訊號感測單元；形成一上板件，其係於一導光板之單 侧表面上於對應於該接觸訊號感測單元之位置，以墨水印 刷並經烘烤後形成有-導光圖案；將該上板件黏附於該下 板件；以及裝設至少-光發射器構裝，該光發射器構裝具 有〜光源，係於該黏附之上板件與下板件間發射光；其中， 該上板件包括一按鍵單元，其製造方法包含下列步驟：於 歷鉍墨水印刷以及烘烤的導光板上部形成一觸動器，其具 有〜凹穴態樣用以觸碰與其對應之該接觸訊號感測單元； 20 200901743 ^網版印财法於簡__造—料線硬化 树月曰，以及硬化該塑造之紫外線硬化型環氧樹脂。 依據柄明之另—目的，該導光板之圖案印刷 错由印刷該導光板薄片的整個表面，或是僅 ^ 溥片之-特定區域所完成。 丨心先板 該導光板的圖案成形，主要是透過在靠近該光源 射點位置處’設計間隔較寬的圖案或是降低 發 二_射入表面之的量，而在遠離該光源之發=置 处，則5又计間隔較緊密的圖案或是提高圖案的密度。 洪烤該上板件的過程包括在溫度範圍為攝氏必 6〇度的烤箱中烘烤，並在室温下自然地硬化。 又 該導光板的材料為聚碳酸酯。 15 f光發射器構裝能夠發射出—種或多種顏色的光。 若使用厚度為〇.4絲之光發射器縣， 度為^或等於(U絲，小㈣2絲。 敬的厚 卢為㈣G.6絲之光發射器構該導光板的厚 度為，或等於〇.2毫米，小於Q4毫米。 予 右使料度為〇.8㈣之絲射轉裝， ，厚度為大於或等於〇.4絲，小於G 5毫米。反，專片 【功效】 鍵裝使用墨水印刷及側發光之電子產品按 八、以方法，鍵盤的按鍵部分可以輕易地製造， 效W的錄部分可缝少的LED膽裝配；而使用 土 P刷方式形成圖案的鍵盤製造方法，可以提供高品質 20 200901743 點，以降低整體 且兼具低製造成本、低原料使用價格的優 成本。 圖式簡單説明】 第一圖係為一種習用行動電話的立體圖. 第二圖為沿著第一圖之b-b剖線@ 狀態 面圖，顯示其背光 第三圖係為-習知應用圓頂開關總成之行動電話 面圖，顯示行動電話之背光狀態； 第四圖係為第三圖所示習知用於行動電話的按鍵裝置 10 的平面圖； 第五圖係為-平面圖’顯示依據本發明—實施例之使 用墨水印刷及側發光方法之電子產品按鍵裝置； 第六圖係為第五圖所示依據本發明—實施例之使用墨 水印刷及側發光方法之電子產品按鍵裝置的剖面圖；土 15 第七圖係為一示意圖，顯示形成於導光板上之導光圖 案的不同範例； 第八圖係為一示意圖，顯示利用墨水印刷方法在導光 板之單面上形成導光圖案； 第九圖係為一示意圖，顯示烘烤形成有如第八圖所示 20之圖案的導光板的方法； 第十圖係為一示意圖，顯示在如第九圖所示之烘烤後 的導光板上形成一按鍵裝置之觸動器的製程範例； 第十—圖係為一示意圖’顯示在如第十圖所形成之該 觸動器内進行模塑加工的製程範例； 12 200901743 第十二圖係為-示意圖’顯示紫外光照射使第十 所示:觸動器内之光硬化型環氧樹脂硬化的過程；Θ 第十三圖係為一示意圖，顯示依據本發明電子產品之 按鍵裝置的外形，透過產品沖壓切斷製程來形成該上^ 5 之外形的過程； 第十四圖係為一示意圖，顯示將依據本發明電子產品 之按鍵裝置的上板件黏附於下板件的過程；以及 第十五圖係為"示意圖，顯示將-光發射器裝設至- 模組之側面的過程’其中，該上板件與該下板件係依第十 10四圖之過程加以黏附。 本發明使用墨水印刷及側發光方法之電子產品按鍵裝 置及其製造方法，將參照隨附圖式詳加介紹。 【實施方式】 第五圖係為一平面圖，顯示依據本發明一實施例之使 用墨水印刷及側發光方法之電子產品按鍵裝置。 如第五圖所示，本發明提供一下板件12，係整合有一 具有夕數圓頂結構之接觸訊號感測單元; 一個或兩個光 功發射器構裝32，係裝設於該下板件12之側面的一預定區 域，以產生背光；一導光板所形成之上板件45，係用以傳 遞自該光發射器構裝32所產生的光；上板件45，係整合有 用以觸碰與其對應之該接觸訊號感測單元13的按鈕單元 42、44。該上板件45的製造方面，係以墨水印刷的方法將 一圖案遮蔽於該導光板片之表面上，之後，經過在一烤箱 13 200901743 内進行烘烤的過程後，係可透過裁切而形成一觸動器。藉 此即可增加其生產力。 第六圖係為第五圖所示依據本發明一實施例之使用墨 水印刷及侧發光方法之電子產品按鍵裝置的剖面圖。 5 如第六圖所示，本發明並未使用習知技術之藉由發光Two ==, due to the limited light emission area of the traditional mobile phone or the back transmitter of the mobile phone, there is no sufficient light and the same light on the keyboard, so there is heat to effectively distinguish the keys. problem. Therefore, in order to provide sufficient backlight, it is necessary to set a number of light emitters, which in turn leads to excessive power, so there is a problem that the battery life is short. In addition, since a large number of light emitters must be provided, there are problems in that the manufacturing process and the structure become complicated, the design is solid, and the manufacturing cost is increased. In order to improve such problems, a reflective film and an optical film are formed on the top side of the dome switch structure and the bottom side of the non-protruding portion of the keyboard to reduce the light-emitting diode elements. The light system emitted from the self-luminous diode element is collected and concentrated at the keyboard, whereby the keyboard can emit high-efficiency light with a small amount of light-emitting diode elements. The second figure is a cross-sectional view of a conventional mobile phone using the dome switch assembly technology, showing the backlight status of the mobile phone. As shown in the second figure, a dome switch assembly 10 is attached to a printed circuit board 30. A light emitter 32 having a light emitting diode is disposed on the printed circuit board 30 200901743. When the dome-shaped switch assembly 10 is used, the number of the light emitters 32 can be reduced due to the reflection effect of the film 16 or the scattering effect. Moreover, even if the position of the light emitter 32 is defined at the center of the printed circuit board 30, the light emitter 32 can still provide sufficient backlighting. In detail, the dome switch assembly 10 adhered to the printed circuit board 30 is regularly disposed below a keyboard 40. In this way, the dome switches 20 of the dome switch assembly 10 can be in contact with the protrusions 44 of the buttons 42 or can be pressurized by the protrusions of the buttons 42 to the dome switch. Each dome switch 20; wherein each button 42 is mounted on the disk 40 corresponding to each of the dome switches 20. According to this configuration, light emitted from each of the light emitters 32 disposed on the printed circuit board 30 is reflected or scattered into the dome switch assembly 1 due to optical reflection or optical scattering. The entire space between the keyboards 〇β and the opaque buttons 42 are transmitted to the outside, so that the user can clearly distinguish the buttons and operate them. That is, when the user opens the top cover of the mobile phone or presses the push button to use the mobile phone, the power is supplied to the light emission 32 set on the printed circuit board 3 () so that the space is based on three degrees. Among the lights emitted, part of the light emitted to the key 40 is supplied to each of the keys 42 on the keyboard 4 = and some of the remaining light is reflected to a keyboard 4 The bottom surface = the bond film 50. The reflected light is oriented toward the circle _1 薄 and the Ϊ reflected light is again reflected to the reflection _ 50 of the keyboard 4Q to provide light to other adjacent buttons 42. The light emitted from the light emitter % 7 200901743 is transmitted through the dome switch assembly 10 and the film 16 of the keyboard 40 and the reflective film 50, and the dome switch assembly 10 is The keyboard 40 is continuously and repeatedly reflected and scattered, so that light of the same brightness for each of the keys 42 of the keyboard 40 can be provided. This is an indirect 5 illumination method that utilizes the scattering of light to cause light emitted from the light emitter to be reflected by the film of the upper plate. The fourth figure is a plan view of a conventional button device for a mobile phone shown in the third figure. As shown in the fourth figure, the light-emitting diode light emitter 32 emits light for the keyboard 4〇 between the keys 42 by an indirect illumination method. Regarding the use of the light scattering indirect illumination method, there is a defect in that when a reflective film is formed on the top side of the dome switch assembly and the bottom side of the keyboard to improve the illumination efficiency, corresponding to the numeric keypad The number of such light-emitting diode elements is not substantially reduced relatively, and their formation, mounting, and arrangement are still cumbersome. That is, such a device and method require a large number of light-emitting diodes, and the process of disposing the light-emitting diode chip on the printed circuit board is complicated, and the process of forming the reflective film is also complicated. Therefore, there are still many problems in how to obtain a cost-effective production process. In addition, the processing cost and manufacturing cost of the raw materials are also very expensive, for example, the keys of the keyboard, that is, the button must be obtained by molding.

That is, in the present invention, light generated by one or two light emitting diode elements 32 disposed on the side of the lower plate member 12 is incident on the light guide plate 110' and the light is passed through the light guide plate. The structure and light guiding pattern of 110 are converted into a surface light source such that the back 10 light can be properly performed at the keyboard position. Since the principle of converting the emitted light through the light guide plate 11 into the surface light source is a well-known technique, the related description will be omitted below. Thereby, since the light emitter package 32 is disposed on the outer side of the keyboard to emit light 'the emitted light is incident on the side surface of the light guide plate 11 and is converted into the surface light source. Therefore, a high-efficiency backlight effect can be obtained by a small number of light-emitting diode elements, and in addition, the light-emitting diode element can be easily mounted and manufacturing cost can be saved. In addition, the light-emitting device assembly 32 disposed on the side of the lower plate member 12 generates a light-based residual rainbow plate member between the service and the lower plate buckle, and is captured in the inner (four) light to be emitted again. To the upper part of the light guide plate, and the backlight of the keyboard has also been executed. Thereby, the symbolic characters that are opaquely printed between the button portions or on the lap portion can be clearly distinguished. This is a splice that emits a transition, and the filament is a light that emits one or more colors, such as blue or white. 14 200901743 The seventh diagram is a schematic diagram showing different examples of light guide patterns formed on the light guide plate.
為了使叹置於該下板件12側面之該光發射器32所收集 的光能夠如表面光源般作為鍵盤的背光，因此必須形成一 5圖案以大面積地反射藉由内部之導光板45全反射所捕捉到 的光。該圖案可依據該鍵盤的位置而以各種不同的形式形 成。如第七圖所示，以點狀圖案為爿，-均勻之圖案6卜 一只在鍵盤部分形成均勻的圖案62、以及一均勻性範圍操 控於距離該光源之遠近的圖案63,皆為可能的圖案形式。 ω如此，可透過在該鍵盤位置上形成各種導光圖案，以有效 率地執行背光。由於該鍵盤位置上的背光，係由設置於該 下板件側面之該光發射器構裝所產生的光所達成 ，因此， 圖案設計的方法係隨著該光源的位置而改變。 在接近該光源之發光點處，圖案的間隔係較寬以減少 I5您集度’進而降低發射至該表面的光量；而圖案的間隔則 密集地形成於遠離該發光點處，以增加密集度，進而提高 發射至該表面的光量’如此係可達成該鍵盤高效能的背 光。此處’聚碳酸醋為令人滿意之導光板材料。其為具有 透明性及優越的機械特性、抗熱性、抗寒性及電氣特性等 各項特性均衡駐程歸，且其鱗以及具有自媳性。 <聚碳酸酉旨的特性為其價格較之前常使用之高純度的丙 細酸樹脂（聚曱基丙烯酸曱脂，ρΜΜΑ)昂貴許多，然而， ，碳酸S旨的強度與抗熱㈣較為優良。其可承受導光圖案 在烤箱中烘烤成型的步驟，且亦可承受形成賴動器過程 15 200901743 中的沖壓製程。 第八圖至第十五圖皆為示意圖，顯示依據本發明之使 用墨水印刷及側發光方法之行動電話鍵盤的製造方法流 程。 5 /第八圖顯示用以在導光板之單面上形成導光圖案的方 法係使用墨水印刷法。當被用來作為導光板之該聚碳酸酯 布100攤開後，該聚碳酸酯布100係被傳送至一圖案模具， α亥圖案杈具係依照特定圖案而設計。依照該設計之圖案蝕 刻的一模具基板107，係置於該聚碳酸酯布1〇〇的上部，且 1〇墨水105係依據該圖案，透過以印刷滾輪1〇3塗佈墨水1〇5的 方式”儿積於該導光板上。至於圖案的墨水印刷方面，係 可使用《亥心鍵破置之上板件的整個表面或是想要印刷的部 二”傳、摘圖案形成方法不同的是，由於本方法之該圖 >、Ρ刷的過㈣單且製程成本較低，因此本方法的優點在 15於該Ϊ子設備按鍵裝置之上板件的生產率增加。 $ 為一不意圖’顯示烘烤形成有如第八圖所示 棬择、二、，板的方法。在烤箱中的烘烤過程，係能多句以 四十^^^^約二十分鐘H較佳可在約攝氏 如鐘。之後，、置於室刀、、田里下自或妙是在約攝氏六十度下烘烤十分 光因今導弁柄而//皿下自…、硬化。當該發射裝置所產生的 導光i以將兮發為表面光源的光時’藉由形成更透明的 將該發崎置難生的光反㈣更好。 弟十圖係為一千音_ 的導光板上Μ :圖’1赫在如第九圖所示之烘烤後 H按鍵裝置<觸動器的製程範例。為了形 200901743 成3亥按鍵單元之觸動器以使具有圖案的該導光板可與其對 應之該訊號感測單元接觸，因此，具有該導光圖案之導光 板110係置放於一基板115上。之後，為穩定地完成沖壓製 程，因此，一具有對應於該接觸訊號感測單元之穿孔的支 撐板in，係置放於該導光板110上。在此狀態下，當依照In order to enable the light collected by the light emitter 32 located on the side of the lower plate member 12 to be used as a backlight of the keyboard as a surface light source, a 5 pattern must be formed to reflect the large area by the inner light guide plate 45. Reflects the captured light. The pattern can be formed in a variety of different forms depending on the position of the keyboard. As shown in the seventh figure, it is possible to use a dot pattern as the 爿, a uniform pattern 6 to form a uniform pattern 62 on the keyboard portion, and a uniformity range to manipulate the pattern 63 from the distance of the light source. Pattern form. Thus, the backlight can be efficiently performed by forming various light guiding patterns on the keyboard position. Since the backlight at the position of the keyboard is achieved by the light generated by the light emitter assembly disposed on the side of the lower plate member, the method of pattern design changes with the position of the light source. At the point of illumination near the source, the spacing of the pattern is wider to reduce I5's concentration, which in turn reduces the amount of light emitted to the surface; and the spacing of the pattern is densely formed away from the point of illumination to increase density In turn, increasing the amount of light emitted to the surface is such that a high-performance backlight of the keyboard can be achieved. Here, 'polycarbonate is a satisfactory light guide plate material. It has a balance of transparency, superior mechanical properties, heat resistance, cold resistance and electrical properties, and its scale and self-sufficiency. <Characteristics of polycarbonate is much more expensive than the high-purity acrylic resin (polyacrylic acid acrylate, ρΜΜΑ) which is often used before. However, the strength and heat resistance of carbonic acid are better. . It can withstand the steps of baking the light guiding pattern in the oven and can also withstand the stamping process in the process of forming the traverse process 15 200901743. The eighth to fifteenth drawings are schematic views showing the flow of the manufacturing method of the mobile phone keypad using the ink printing and side lighting methods according to the present invention. 5 / Figure 8 shows a method for forming a light guiding pattern on one side of a light guide plate using an ink printing method. When the polycarbonate cloth 100 used as a light guide plate is spread out, the polycarbonate cloth 100 is conveyed to a pattern mold, and the alpha-patterned cookware is designed in accordance with a specific pattern. A mold substrate 107 etched according to the design pattern is placed on the upper portion of the polycarbonate cloth, and the ink 105 is applied to the ink 1 〇 5 by the printing roller 1 〇 3 according to the pattern. The method is integrated on the light guide plate. As for the ink printing of the pattern, it is possible to use the "Haixin key to break the entire surface of the upper plate or the part 2 to be printed". Yes, since the figure of the method>, the brushed (four) single and the process cost are low, the advantage of the method is that the productivity of the board above the button device of the device is increased. $ is a non-intentional 'showing method of baking to form a choice, two, and a plate as shown in the eighth figure. In the baking process in the oven, the system can be multi-sentences forty-five ^^^^ for about twenty minutes, preferably at about ten degrees Celsius. After that, it is placed in the room knife, and the field is underneath or it is baked at about 60 degrees Celsius. When the light guide i generated by the emitting device emits light as a surface light source, it is better to form a more transparent light that is difficult to generate.

However, the molded epoxy resin can maintain the conventional technique of UV hardening by 2 17 200901743. The advantage is that it can reduce the touch of the button. The method of manufacturing the button is not a tenth diagram, which is a schematic diagram of the shape of a 5-button device through the process of producing an electronic product other than the present invention. In order to maintain the same interval at the up-cutting process to form the upper plate member, the button has the button turned to find the upper plate member attached to the forming 160' as produced by the stamping process. The 10 board is made of the upper part according to the outer shape of the button device. The light is intended to show the process of the upper plate member of the secret device of the electronic product according to the present invention. For example, the upper plate member η〇 obtained by the thirteenth riding show (4) is I, and the τ plate member 12 formed with a plurality of contact signal sensing units maintains a pre 15 = still degree, and the upper plate is fixed. The member 110 and the lower plate member 12 enable them to be stable and do not move. Therefore, a main spacer reinforcing support member is formed between the upper plate member 110 and the outer side of the lower plate member 12. The upper plate member 110 and the lower plate member 12 are then adhered to the reinforcing support member 170 through an adhesive 175, respectively. The fifteenth diagram is a schematic view showing the process of mounting a light emitter to the side of a module, wherein the upper panel and the lower panel are adhered according to the process of the fourteenth embodiment. Referring to Figure 15, when one or more of the light emitters are mounted on the side of the module, the one or more light emitter configurations are likely to be placed at position A or position Η. In addition, according to the light guide chart 18 200901743, the selection of the position of the light emitter assembly can be arranged to an appropriate position other than A or ’ to perform a high performance backlight. At the same time, it is preferred that the light guide plate having a specific thickness be used in accordance with the thickness of the light emitter package 32. This thickness ratio is very suitable for collecting light generated from the light emitter by a polycarbonate (hereinafter abbreviated as PC). That is, if a light emitter having a thickness of 0.4 mm is used, the thickness of the pc sheet 11 is preferably greater than or equal to 〇1 mm, less than 〇2 mm, and light emission having a thickness of 0.6 mm is used. 2), the thickness of the thin plate 110 is greater than or exclusively for 0.2 mm, less than millimeters. If a light emitting transmissive having a thickness of 0.8 mm is used, the thickness of the pc thin plate m is greater than or equal to 0.4 mm, less than 0.5 mm. 15 20 Thus, unlike the method of forming a pattern by using the conventional pressurizing device through the processes of the eighth to fifteenth drawings, the process can be simplified by forming a pattern by using an ink printing method. And to ensure the productivity of the product. In addition, compared with the method of using the indirect illumination of the county by the indirect illumination of the button, if used in the side of the proposed side of the invention The emitting device, the light generated by the emitting device is converted into a source by the light guide plate having the light guiding pattern, and the light collected between the upper plate and the lower plate is induced to be illuminated. Therefore, it is available The result of the backlight illumination of the amount of light-emitting diode illumination. The invention is not in violation of the spirit and scope of the present invention, and those skilled in the art can easily engage in various modifications and changes, so that it is clear The scope covers the following additional application scopes and the corresponding [2009] application and the [industrial applicability] source, and will induce the backlight of the upper plate and the lower plate. Therefore, it can be used in a small amount. Illumination, state to perform high illumination backlight port according to the present invention provides ink printing and side illumination electronic production of the key I and its manufacturing method, the process can be simplified and can ensure that the product is issued, Green uses a small amount of light-emitting device disposed on the side, and the light produced by the dry film is lower in cost by the light guide plate on which the light guiding pattern is formed, and the manufacturing process is (4) m: $, due to the provision of the raw material. The key of the electronic product is used for garbage supply, so it is economical. 20 200901743 [Simple description of the diagram] The first picture is the stand of the mobile phone.
