Description
本發明關於一種觸控鍵盤,尤指一種發光觸控鍵盤之背光模組。The present invention relates to a touch keyboard, in particular to a backlight module of a light-emitting touch keyboard.
一般廣泛使用的人機輸入裝置主要為鍵盤與滑鼠。一般筆記型電腦或平板電腦皆有觸控板或是螢幕可觸控,故可省去滑鼠。桌上型電腦或是智慧電視原則上仍需滑鼠。對此,市面上已有結合觸控功能的鍵盤,以減少外接裝置的數量。又,配備此類鍵盤的筆記型電腦可省去觸控板,增加下蓋配置彈性,例如加大鍵帽,配置朝上擴音的喇叭等。此類鍵盤(或稱觸控鍵盤)能感應使用者於鍵帽上的移動以作為觸控輸入,按鍵本身亦可為使用者按壓以作按鍵輸入。觸控鍵盤在功能切換時(例如在按鍵模式與觸控模式間之切換),觸控鍵盤本身原則上不會有明顯的指示,.使得使用者需猜測觸控鍵盤目前的模式以能正確使用,造成操作上的不便。此外,觸控鍵盤可能非所有按鍵均會參與觸控感應,故若非觸控鍵盤本身有醒目標示或使用者特別記住,使用者原則上無從知悉觸控感應的範圍,此亦造成操作上的不便。Generally, the widely used human-computer input devices are mainly keyboards and mice. Generally, notebook computers or tablet computers have touchpads or touchscreens, so the mouse can be omitted. Desktop computers or smart TVs still require a mouse in principle. In this regard, keyboards with touch functions are available on the market to reduce the number of external devices. In addition, a notebook computer equipped with such a keyboard can omit the touchpad, and increase the flexibility of the lower cover configuration, such as increasing the keycaps, and configuring upward-facing speakers. This type of keyboard (or called a touch keyboard) can sense the user's movement on the keycap for touch input, and the keys themselves can also be pressed by the user for key input. When the touch keyboard switches functions (such as switching between key mode and touch mode), the touch keyboard itself will not have obvious indications in principle, so that users need to guess the current mode of the touch keyboard to use it correctly. , causing inconvenience in operation. In addition, not all keys of the touch keyboard may participate in touch sensing. Therefore, unless the touch keyboard itself has a conspicuous indication or the user remembers it, the user cannot know the range of the touch sensing in principle, which also causes operational problems. inconvenient.

Therefore, the light-emitting touch keyboard can provide an optical indication to the touch area through the light guide structure of the backlight module, so as to remind the user of the range of the touch area.

關於本發明之優點與精神可以藉由以下的發明詳述及所附圖式得到進一步的瞭解。The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings.
請參閱第1至4圖。根據一第一實施例之一發光觸控鍵盤1包含一裝置殼體10、複數個鍵帽12 (於第3圖中僅擇一標示)、一底板14、複數個升降機構16 (僅繪示於第4圖中以簡化圖式)、一薄膜電路板18、一觸控感應層20、一背光模組22及一控制器24。裝置殼體10包含一上殼102及一下殼104,其他構件容置其間。該複數個鍵帽12設置於底板14之上且露出於上殼102。該複數個升降機構16 (例如但不限於剪刀腳支架)連接至該複數個鍵帽12與底板14之間。薄膜電路板18及觸控感應層20疊置於底板14上。鍵帽12能經由對應的升降機構16相對於底板14、薄膜電路板18及觸控感應層20上下移動(即沿垂直方向Dv (以雙頭箭頭表示於圖中)移動);被按壓的鍵帽12可經由設置於其下方對應的彈性復位件17 (僅繪示於第4圖中以簡化圖式;例如但不限於橡膠圓突)向上回到原位。薄膜電路板18 (以單一結構板件繪示以簡化圖式)對應該複數個鍵帽12具有複數個按鍵開關18a (於第3圖中以帶影線圓圈表示)。控制器24 (例如以電路板模組實作,其包含一印刷電路板及設置於印刷電路板上之處理/控制晶片、連接介面及所需電子元件等)與薄膜電路板18、觸控感應層20及背光模組22電連接。鍵帽12可被按壓以觸發對應的按鍵開關18a,以作為按鍵輸入。觸控感應層20能感應手指3 (僅繪示於第4圖中)在鍵帽12頂面12a上的觸碰操作(例如移動),以作為觸碰輸入。背光模組22具有一導光結構222,設置於該複數個鍵帽12下方。背光模組22利用導光結構222以提供該複數個鍵帽12背光。See Figures 1 to 4. A light-emitting
請亦參閱第5圖,其為觸控感應層20電極佈局之示意圖,鍵帽12於觸控感應層20上之按鍵投影區12b以虛線繪示。於第一實施例中,觸控感應層20包含複數個第一電極串列202 (每一串列包含複數個第一電極202a)及複數個第二電極串列204 (每一串列包含複數個第二電極204a),交錯排列以使電極202a、204a均勻分布。該複數個鍵帽12水平排列(沿水平方向Dh)於觸控感應層20上方,觸控感應層20透過該複數個第一電極串列202及該複數個第二電極串列204感應手指3在鍵帽12頂面12a上的觸碰操作。為簡化圖式,觸控感應層20以單一結構板件表示。於實作上,觸控感應層20可由三層結構實施;其中,第一電極串列202及第二電極串列204分別設置於上、下基板上,兩者之間以間隔層隔離第一電極串列202及第二電極串列204。但實作上不以此為限。例如,第一電極串列202及第二電極串列204可設置於同一基板之同一表面上,交錯處(即電極連接線)可絕緣結構,以避免第一電極202a間的連接線與第二電極204a間的連接線接觸。又例如,第一電極串列202及第二電極串列204可設置於同一基板之不同表面上,此基板本身即可提供第一電極串列202與第二電極串列204間之絕緣。Please also refer to FIG. 5 , which is a schematic diagram of the electrode layout of the
於第一實施例中,觸控感應層20的感應區20a (以粗鏈線表示其範圍於第3、5圖中;即該複數個第一電極串列202及該複數個第二電極串列204之分布區域)並未涵蓋所有鍵帽12的按鍵投影區12b;換言之,觸控感應層20不是對所有鍵帽12的頂面12a皆提供觸控感應。因此,發光觸控鍵盤1於該複數個鍵帽12的頂面12a上可定義出一觸控區13a (如第1圖中粗鏈線所包圍之區域)及一非觸控區13b (如第1圖中細鏈線所包圍並扣除觸控區13a之區域)。觸控區13a於觸磁感應層20上之投影與感應區20a相同(亦即於第5圖中,粗鏈線所包圍之區域亦相當於觸控區13a之投影)。原則上,觸控感應層20僅感應手指3在觸控區13a內的觸碰操作。又,於第一實施例中,位於觸控區13a內之鍵帽12的頂面12a大致共平面,便於手指3滑動。In the first embodiment, the
請參閱第5、6圖。於第一實施例中,於觸控區13a內的每一個鍵帽12尺寸相同。於感應區20a內的每一個按鍵投影區12b涵蓋相同的鍵面電極圖案。於感應區20a內,對應每一個按鍵投影區12b定義一鍵隙佈局投影12c (以帶影線之環狀區域表示於第6圖中),使得鍵隙佈局投影12c圍繞對應的按鍵投影區12b。每一個鍵隙佈局投影12c涵蓋相同的鍵隙電極圖案。此結構配置可提高觸控感應數據的規律性,減少觸控軌跡的斷點、提高觸控感應的靈敏度,也能簡化觸控電極的設計複雜度。此外,於第一實施例中,觸控感應層20對應每一個升降構件16具有複數個穿孔206 (為簡化圖式,僅顯示於第6圖中),以供升降構件16與底板14連接。穿孔206位於鍵帽12正下方,會影響鍵面電極圖案。按鍵投影區12b的鍵面電極圖案上具有一穿孔佈局206a (或謂其由對應按鍵投影區12b的穿孔206定義出)。每一個按鍵投影區12b的鍵面電極圖案的穿孔佈局206a相同,此亦有助於使每一個按鍵投影區12b保持涵蓋相同的鍵面電極圖案。另外,薄膜電路板18位於觸控感應層20與底板14之間,可抑制薄膜電路板18電路對觸控感應層20感應的影響。薄膜電路板18亦對應每一個升降構件16具有複數個穿孔(未繪示於圖中,以簡化圖式),以供升降構件16與底板14連接。See Figures 5 and 6. In the first embodiment, each
請參閱第1至3、7、8圖;其中,鍵帽12於導光結構222上之按鍵投影區12b'以虛線繪示於第8圖中。於第一實施例中,背光模組22還包含複數個第一光源224及複數個第二光源226,與控制器24電連接(例如經由軟性電路板223)。導光結構222疊置於觸控感應層20下方並包含一第一導光片2222及一第二導光片2224,該複數個第一光源224及複數個第二光源226分別第一導光片2222及第二導光片2224設置。第一導光片2222具有一第一出光面2222a,第一出光面2222a具有一輪廓2222b,與觸控區13a (如第1圖中粗鏈線所包圍之區域)的輪廓匹配。第二導光片2224具有一第二出光面2224a,第二出光面2224a具有一輪廓2224b,與非觸控區13b (如第1圖中細鏈線所包圍並扣除觸控區13a之區域)的輪廓匹配;從另一方而言,非觸控區13b圍繞觸控區13a而呈環狀,第二出光面2224a亦圍繞第一出光面2222a而呈環狀。藉此,控制器24能控制該複數個第一光源224發射光線,進入第一導光片2222並經第一導光片2222導引以自第一出光面2222a射出第一導光片2222,照射對應觸控區13a之複數個鍵帽12 (即提供其背光);同理,控制器24亦能控制該複數個第二光源226發射光線,進入第二導光片2224並經第二導光片2224導引以自第二出光面2224a射出第二導光片2224,照射對應非觸控區13b之複數個鍵帽12 (即提供其背光)。另外,導光結構222亦對應每一個升降構件16具有複數個穿孔(未繪示於圖中,以簡化圖式),以供升降構件16與底板14連接。Please refer to FIGS. 1 to 3, 7, and 8; wherein, the
因此,於實際應用上,控制器24可配合發光觸控鍵盤1的運作模式以選擇性地控制該複數個第一光源224及該複數個第二光源226發射光線,以提供該複數個鍵帽12不同的背光組合。例如,當發光觸控鍵盤1處於觸控模式時,控制器24可控制第一光源224發射光線且關閉第二光源226,使得第一光源224對觸控區13a提供之背光較為明顯。又例如,當發光觸控鍵盤1處於按鍵模式時,控制器24可控制第一光源224及第二光源226均發射光線,使得觸控區13a及非觸控區13b均能獲得背光;其中,第一光源224及第二光源226可發射同色光線。Therefore, in practical applications, the
此外,於第一實施例中,第一出光面2222a與觸控區13a的輪廓匹配是透過第一出光面2222a的輪廓2222b與觸控區13a的輪廓相同而實現,第二出光面2224a與非觸控區13b的輪廓匹配是透過第二出光面2224a的輪廓2224與非觸控區13b的輪廓相同而實現;但實作上不以此為限。原則上,第一出光面2222a與觸控區13a的輪廓相似且大小相近,使得經由第一出光面2222a提供之背光能對觸控區13a的範圍提供光學指示,便可算是第一出光面2222a與觸控區13a於輪廓上匹配;第二出光面2224a與非觸控區13b的輪廓匹配亦同。另外,因非觸控區13b圍繞觸控區13a,故第二出光面2224a亦相對於垂直方向Dv圍繞第一出光面2222a,亦即第二導光片2224相對於垂直方向Dv圍繞第一導光片2222。In addition, in the first embodiment, the contour matching of the first
此外,於第一實施例中,第一導光片2222及第二導光片2224水平相鄰,使得第一導光片2222及第二導光片2224可大致上拼合在一起。但實作上均不以此為限。此外,於第一實施例中,第一導光片2222與第二導光片2224間實作上可存有一介質(未標示於圖中);此介質即相當於位於第一出光面2222a的輪廓2222b處。此介質(例如但不限於空氣)的折射率大於第一導光片2222及第二導光片2224之折射率,可抑制第一導光片2222及第二導光片2224內之光線相互傳遞,進而使得於觸控模式時,第一光源224經由第一導光片2222對觸控區13a提供之背光更為明顯。又,於實作上,該介質亦可為不透光材質,以阻止第一導光片2222及第二導光片2224內之光線相互傳遞,更能使第一光源224經由第一導光片2222對觸控區13a提供之背光更為明顯。In addition, in the first embodiment, the first
此外,於實作上,透過設計每一個第一光源224的設置位置及朝向,可提高經由第一出光面2222a提供背光的均勻度。如第7、8圖所示,於第一實施例中,該複數個第一光源224位於第一出光面2222之同一側且以不同方向發射光線(以細線箭頭表示於圖中)。其中,該複數個第一光源224的設置不以每一個第一光源224均以不同的方向設置為限。第一導光片2222對應該複數個第一光源224形成容置孔2222c,以容置對應的第一光源224,使得第一光源224位於第一導光片2222的內側。於實作上,第一光源224亦可設置於第一導光片2222的邊緣處(即位於第一導光片2222與第二導光片2224之間)。第7、8圖所呈現的第一光源224的設置位置及朝向僅為示例,第一光源224的具體設置可依實際產品設計而定,不另贅述。前述說明亦適用於第二光源226的設置位置及朝向,亦不另贅述。In addition, in practice, by designing the location and orientation of each
另外,於實作上,背光模組22可針對第一導光片2222更包含能發射其他色光之光源,進而增加背光模組22提供該複數個鍵帽12更多種的背光組合。如第9圖所示,於一變化例中,背光模組22'相對於第8圖之背光模組22更包含複數個第三光源228 (以帶影線方框表示於圖中)。為便於說明,該複數個第三光源228與該複數個第一光源224一對一相鄰設置於對應的容置孔2222c中;亦即該複數個第三光源228亦鄰近第一導光片2222設置,第三光源228發射之光線進入第一導光片2222並經第一導光片2222導引以自第一出光面2222a射出第一導光片2222,照射對應觸控區13a之複數個鍵帽12。第一光源224及第三光源228發射不同色光線。例如,第一光源224及第二光源226為藍光發光二極體(light-emitting diode,LED),第三光源228為紅光LED。藉此,當第一光源224及第三光源228同時開啟時,藍光和紅光於第一導光片2222內可混合成紫光並自第一出光面2222a射出第一導光片2222。於實作上,例如,當發光觸控鍵盤1處於觸控模式時,此紫光可作為觸控區13a (參考第4圖)之背光;當發光觸控鍵盤1處於觸控模式時,可控制第一光源224及第二光源226發光並關閉第三光源228,使得觸控區13a及非觸控區13b均能獲得藍色背光。In addition, in practice, the
另外,請回到第4、7、8圖。於第一實施例中,導光結構222由兩個共平面設置的導光片(即第一導光片2222及第二導光片2224)形成,但實作上不以此為限。例如,導光結構222改由單一導光片實作,其中於此導光片上對應觸控區13a形成深壓痕(例如深度大於導光片厚度的三分之二),此深壓痕將此單一導光片大致上分成兩個結構相連的導光部分。此深壓痕的位置即相當於導光結構222的第一導光片2222的輪廓(即相當於輪廓2222b),使得此單一導光片於深壓痕內側的表面即相當於第一出光面2222a,且於深壓痕內側的表面即相當於第二出光面2224a。其中,雖然這兩個導光部分間結構上相連(即於該深壓痕下方),使得在這兩導光部分內的光線會部分相互進入,但是外溢至另一導光部分的光線強度原則上遠小於在原導光部分的光線強度,使得經由第一出光面2222a提供之背光強度明顯大於由第二出光面2224a提供之背光強度,此仍能有效地對觸控區13a提供光學指示。Also, please go back to Figures 4, 7, and 8. In the first embodiment, the
另外,於發光觸控鍵盤1之背光模組22中,第一光源224及第二光源226均以LED實作,邏輯上可視為點光源,故背光模組22使用了多個第一光源224及第二光源226以便於產生均勻的背光(搭配導光結構222)。於實作上,第一光源224及第二光源226的設置數量可依光源型式而定,且不以相同光源型式為限。此外,於發光觸控鍵盤1之背光模組22中,用於對觸控區13a提供光學指示之背光是由第一光源224搭配(導光結構222的)第一導光片2222而形成,但實作上不以此為限。In addition, in the
請參閱第10、11圖;其中,於第11圖中,鍵帽12之按鍵投影區12b"以虛線繪示。根據一第一實施例之一發光觸控鍵盤4與發光觸控鍵盤1結構相似,並沿用發光觸控鍵盤1之元件符號。於後文中,關於發光觸控鍵盤4之說明,請亦參閱前文發光觸控鍵盤1各構件及其變化例之相關說明及圖式,不另贅述。發光觸控鍵盤4與發光觸控鍵盤1主要差異在於發光觸控鍵盤4的背光模組42的導光結構422係用於對位於非觸控區13b內之鍵帽12提供背光,背光模組42的複數個第一光源424則不經導光結構422而提供位於觸控區13a內之鍵帽12提供背光。於背光模組42中,導光結構422的出光面422a與非觸控區13b輪廓匹配。該複數個第二光源226發射之光線進入導光結構422並經導光結構422導引以自第二出光面422a射出導光結構422,照射對應非觸控區13b之複數個鍵帽12 (即提供其背光)。該複數個第一光源424位於對應觸控區13a之複數個鍵帽12下方,導光結構422圍繞該複數個第一光源424。每一個第一光源424對應一個鍵帽12,第一光源424向上發光以直接對對應的鍵帽12提供背光。此結構配置便於調整對應觸控區13a之背光,例如用以提高背光均勻度、產生特定背光效果、與對應非觸控區13b的背光一致等。藉此,與發光觸控鍵盤1相當,發光觸控鍵盤4亦能配合運作模式以選擇性地控制該複數個第一光源424及該複數個第二光源226發射光線,以提供該複數個鍵帽12不同的背光組合。
以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。
