Description
本發明係有關於一種觸控面板，特別是指一種觸控面板之具單一偵測模組的位置偵測裝置。The present invention relates to a touch panel, and more particularly to a position detecting device with a single detecting module of a touch panel.
觸控面板（Touch Panel）起源於1970年代，美國軍方為軍事用途而發展，1980年代移轉給民間使用，進而發展為各式用途。現階段由於述求使用便利，所以過去傳統輸入裝置如鍵盤（Keyboard）、滑鼠（Mouse）、軌跡球（Trackball）、軌跡點（Track Point）等產品，已經無法符合市場需求，而觸控面板因具備簡單操作、容易使用的特性，所以1999年開始被廣泛應用在各項消費性電子終端產品上，由過去配角的身分，一躍成為關鍵零組件之一，甚至將朝向整合性產業方向發展，因此備受各界期待。
觸控面板為一貼附在映像管或液晶顯示器上的輸入裝置，其功能在於使一般民眾藉由指示器（Pointer），例如手指或觸控筆，輕壓顯示器面板上的選項，即可完成資料傳輸或閱讀螢幕上的訊息。觸控面板的應用範圍相當廣泛，包括：（1）可攜式電子產品及通訊產品：如P D A、平板電腦、數位攝影機與3 G手機等；（2）金融或商業用途：如提款機、銷售系統與遠端視訊會議；（3）工業用途：工廠自動化控制系統、中央監控系統、工作站作業系統；（4）公共資訊用途：機場、車站或商場的導覽服務、簡報說明及資料查詢等。
現今，用於偵測指示器壓觸面板之座標係有多種方式，例如電容式偵測與電阻式偵測，即一般所稱的電阻式觸控面板與電容式觸控面板。此外，現今更有利用光學方式偵測指示器壓觸面板之座標。電阻式觸控面板是一種觸壓感測裝置，指示器必須施力向下壓觸電阻式觸控面板以產生電阻變化，控制電路才能偵測出指示器壓觸面板之座標。當指示器施力向下壓觸面板時，係會導致電子裝置受到衝擊甚至用力過大而推倒電子裝置。此外，由於電阻式觸控面板必須設置透明電阻層於顯示面板，因此會降低面板顯示的亮度。
電容式觸控面板，係設置具有金屬層之玻璃於顯示面板。指示器觸壓電容式觸控面板時，控制電路係會量測到觸控位置之電容值，進而轉換為位置座標。然而，電容式觸控面板僅能用於導電材質之指示器，例如手指，所以電容式觸控面板於使用上係有一定之限制。此外，由於電容式觸控面板必須設置具有金屬層之玻璃於顯示面板，所以因此會降低面板顯示的亮度。
光學式觸控面板，係藉由影像感測器擷取面板之表面的觸控影像，進而藉由影像處理器處理所擷取之觸控影像，而計算出指示器壓觸面板之座標。但是，現今光學式觸控面板仍具有如何清晰擷取觸控影像之問題，若無法擷取到清晰之觸控影像，影像處理器即無法精確算出指示器壓觸面板之座標。由於光學觸控面板具有很多優點，所以近年來發展很多型態之光學式觸控面板，例如美國申請案公開第2004/0149892A1號與2009/0146973號，以及美國專利第7274352B2號與7538759B2號。然而，上述習用光學式觸控面板之偵測裝置係採用多個光源照射面板之表面，如此會提高成本與耗電量。
另外，美國申請案公開第2007/0089915A1號，其利用一鏡頭、一影像感測器與一菱鏡，鏡頭與影像感測器之間設置菱鏡，鏡頭顯示之觸控影像經由菱鏡折射至影像感測器，以供影像感測器擷取。由於，此習用技術利用菱鏡將觸控影像折射至影像感測器，所以成本較高，且結構較為複雜。此外，此習用技術之設計方式，並無法適用於具反射材質的指示器。
此外，以上所提之位置偵測裝置大部分都需要使用至少兩個偵測模組，以從不同角度擷取觸控影像。雖然美國專利第7274356B2號與美國申請案公開第2009/0146973A1號，係提出使用單一感測器在搭配數個鏡子分別安裝於相鄰的感測區域之邊框，其用意為希望能透過鏡子顯示感測區域的不同角度的影像。但是，其運用於多點觸控時，係不容易分辨鏡子所產生的虛假影像與實際在觸控區域中的真實物體，此問題將提高影像處理器的運算複雜度，甚至進一步造成辨識錯誤，而無法精確得知指示器壓觸面板之座標。
因此，本發明即針對上述問題而提出一種觸控面板之位置偵測裝置，其僅具有單一偵測模組，而不僅可改善上述習用缺點，又可達到降低成本、減少厚度與耗電量之目的，以解決上述問題。
The Touch Panel originated in the 1970s, and the US military developed for military use. In the 1980s, it was transferred to civilian use and developed into various uses. At present, due to the convenience of the description, in the past, traditional input devices such as keyboard, mouse, trackball, track point and other products have been unable to meet the market demand, and the touch panel Because of its simple operation and easy-to-use characteristics, it has been widely used in various consumer electronic terminal products since 1999. It has become one of the key components in the past, and will even develop towards the integrated industry. Therefore, it is expected by all walks of life.
The touch panel is an input device attached to the image tube or the liquid crystal display, and the function is to enable the general public to lightly press an option on the display panel by using a pointer, such as a finger or a stylus. Transfer data or read the message on the screen. Touch panels are used in a wide range of applications, including: (1) portable electronic products and communication products: such as PDAs, tablets, digital cameras and 3G mobile phones; (2) financial or commercial uses: such as cash machines, Sales system and remote video conferencing; (3) Industrial use: factory automation control system, central monitoring system, workstation operating system; (4) public information use: navigation services, briefing instructions and data inquiry for airports, stations or shopping malls, etc. .
Nowadays, there are various ways to detect the coordinates of the indicator pressure touch panel, such as capacitive detection and resistive detection, which are generally referred to as resistive touch panels and capacitive touch panels. In addition, the coordinates of the indicator's pressure touch panel are optically detected today. The resistive touch panel is a touch-sensing device. The indicator must apply force to press down the resistive touch panel to generate a resistance change, and the control circuit can detect the coordinates of the indicator press-touch panel. When the indicator exerts a force to press down on the panel, the electronic device is subjected to an impact or even excessive force to push down the electronic device. In addition, since the resistive touch panel must be provided with a transparent resistive layer on the display panel, the brightness of the panel display is lowered.
A capacitive touch panel is provided with a metal layer of glass on a display panel. When the indicator touches the capacitive touch panel, the control circuit measures the capacitance value of the touch position and converts it into a position coordinate. However, the capacitive touch panel can only be used for indicators of conductive materials, such as fingers, so the capacitive touch panel has certain limitations in its use. In addition, since the capacitive touch panel must be provided with a metal layer of glass on the display panel, the brightness of the panel display is reduced.
The optical touch panel calculates the coordinates of the indicator pressure touch panel by the image sensor capturing the touch image on the surface of the panel and processing the captured touch image by the image processor. However, today's optical touch panels still have the problem of how to capture the touch images clearly. If the clear touch images cannot be captured, the image processor cannot accurately calculate the coordinates of the indicator pressure touch panel. Since optical touch panels have many advantages, many types of optical touch panels have been developed in recent years, such as U.S. Patent Application Publication Nos. 2004/0149892A1 and 2009/0146973, and U.S. Patent Nos. 7,274,352 B2 and 7,538,759 B2. However, the above-mentioned conventional optical touch panel detecting device uses a plurality of light sources to illuminate the surface of the panel, which increases cost and power consumption.
In addition, U.S. Application Publication No. 2007/0089915A1 utilizes a lens, an image sensor and a prism, and a lens is arranged between the lens and the image sensor, and the touch image of the lens display is refracted to the lens through the mirror. Image sensor for image sensor capture. Because this conventional technology uses a prism to refract the touch image to the image sensor, the cost is high and the structure is complicated. In addition, the design of this conventional technology cannot be applied to indicators with reflective materials.
In addition, most of the position detecting devices mentioned above need to use at least two detecting modules to capture touch images from different angles. Although U.S. Patent No. 7,274,356 B2 and U.S. Application Publication No. 2009/0146973 A1, it is proposed to use a single sensor to be mounted on a frame of an adjacent sensing area with a plurality of mirrors, which is intended to display a sense through the mirror. Measure images from different angles of the area. However, when it is applied to multi-touch, it is not easy to distinguish the false image generated by the mirror from the real object in the touch area. This problem will increase the computational complexity of the image processor and even further cause identification errors. The coordinates of the indicator's pressure touch panel cannot be accurately known.
Therefore, the present invention provides a position detecting device for a touch panel that has only a single detecting module, and can not only improve the above-mentioned conventional disadvantages, but also achieve cost reduction, thickness reduction, and power consumption. Purpose to solve the above problem.

茲為使 貴審查委員對本發明之技術特徵及所達成之功效更有進一步之瞭解與認識，謹佐以較佳之實施例圖及配合詳細之說明，說明如後：
首先，請參閱第一圖，係本發明之一較佳實施例之位置偵測裝置設置於觸控面板的上視圖。如圖所示，本發明觸控面板之位置偵測裝置係包含至少一光源20、一第一鏡體23、一第二鏡體25與一偵測模組30，光源20設置於一觸控面板10之邊緣。於此實施例中，兩光源20係設置於觸控面板10之一長邊緣的兩端，以用於產生光線而照射於觸控面板10之表面。第一鏡體23與第二鏡體25分別設置於觸控面板10之邊緣的第一端與第二端，以顯示觸控面板10之表面的一第一觸控影像與一第二觸控影像。由於第一鏡體23與第二鏡體25設置於不同位置，所以可顯示觸控面板10之不同角度的觸控影像，以供偵測模組30擷取。於此實施例中，第一鏡體23與第二鏡體25係設置於觸控面板10之另一長邊緣的兩端。
復參閱第一圖，偵測模組30設置於觸控面板10之邊緣，且位於第一鏡體23與第二鏡體25之間，以用於擷取第一鏡體23所顯示之第一觸控影像與第二鏡體25所顯示之第二觸控影像，如此即擷取到觸控面板10表面之不同位置的觸控影像，而供影像處理器（圖未示）依據偵測模組30所擷取到之第一觸控影像與第二觸控影像，而計算出一指示器（Pointer）壓觸觸控面板10之座標，進而傳送至系統主機，以執行對應之系統功能。上述指示器例如為使用者之手指或者觸控筆。於此實施例中，偵測模組30設置於觸控面板10之長邊緣的中間，且本發明之第一鏡體23與第二鏡體25之一較佳實施例為一柱面鏡。
由上述說明可知，本發明僅需單一偵測模組30及兩鏡體23與25，即可擷取到觸控面板10之表面之不同位置的觸控影像，以供影像處理器依據不同位置之第一觸控影像與第二觸控影像，而計算出指示器壓觸觸控面板10之座標。由於本發明之位置偵測裝置僅需要單一偵測模組30，所以可有效降低成本。
本發明為了讓光源20之光線可均勻照射於觸控面板10之表面，更可包含有至少一光傳輸元件21。於此實施例中，觸控面板10之三個邊緣係分別設置有光傳輸元件21，該些光傳輸元件21分別連接於光源20，用於傳輸光線而均勻照射觸控面板10之表面。光傳輸元件21之實施例可為壓克力或者光纖（Optical Fiber），而光源20之一較佳實施例可為一LED燈。由於本發明利用較少之光源20即可均勻照射觸控面板10之表面，所以相較於習用技術必須使用多個光源，本發明係可降低成本與降低耗電量。
復參閱第一圖，本發明在觸控面板10之邊緣更設有一第一放大鏡40與一第二放大鏡42，第一放大鏡40設置於第一鏡體23與偵測模組30之間，以放大第一鏡體23所顯示之第一觸控影像。第二放大鏡42設置於第二鏡體25與偵測模組30之間，以放大第二鏡體25所顯示之第二觸控影像。藉由第一放大鏡40與第二放大鏡42放大第一鏡體23與第二鏡體25所顯示之第一觸控影像與第二觸控影像，可讓偵測模組30更清晰擷取第一觸控影像與第二觸控影像。
請參閱第二圖，係本發明之另一較佳實施例之位置偵測裝置設置於觸控面板的上視圖。如圖所示，此實施例不同於上一實施例在於，此實施例之觸控面板10更加設有兩個光源20，其可設置於觸控面板10之另一長邊緣的兩端，也就是四個光源20分別設置於觸控面板10之四個角落，並連接設置於觸控面板10之三邊緣的光傳輸元件21，以增加光線照射觸控面板10的亮度。本實施例主要是運用於大面積之觸控面板10，而可增設光源20於觸控面板10。
請參閱第三圖與第四圖，係本發明之一較佳實施例之位置偵測裝置之偵測模組的立體圖與前視圖。如圖所示，本發明之偵測模組30包含一板體32、一第一平面鏡34、一第二平面鏡35與一影像感測器36。第一平面鏡34與第二平面鏡35分別設置於板體32上方，且第一平面鏡34與第二平面鏡35相鄰，第一平面鏡34與第二平面鏡35分別相對於第一鏡體23與第二鏡體25。第一平面鏡34與第二平面鏡35分別呈一角度設置於板體32，此角度為43度～45度之間，而較佳角度為45度。板體32更設有一第一開孔31與一第二開孔33，第一開孔31與第二開孔33之設置方式相同，第一開孔31與第二開孔33之位置相對於第一平面鏡34與第二平面鏡35。影像感測器36設置於板體32之下方而對應第一開孔31與第二開孔33，且相對於第一平面鏡34與第二平面鏡35。
第一平面鏡34與第二平面鏡35用於顯示第一鏡體23與第二鏡體25所顯示之第一觸控影像與第二觸控影像，而影像感測器36經由第一開孔31與第二開孔33而擷取到第一平面鏡34與第二平面鏡35所顯示之第一觸控影像與第二觸控影像，並傳輸所擷取到之第一觸控影像與第二觸控影像至影像處理器。指示器壓觸觸控面板10時，因為指示器會擋住光線，所以被指示器所壓觸之位置即會產生一黑影，如此影像感測器36所擷取到之第一觸控影像與第二觸控影像中也會具有黑影，因此影像處理器處理擷取到之第一觸控影像與第二觸控影像，而計算出第一觸控影像與第二觸控影像中之黑影的位置，即可得知指示器壓觸觸控面板10之座標。
由於本發明設置第一鏡體23與第二鏡體25於觸控面板10之邊緣的兩端，所以第一鏡體23與第二鏡體25可以在不同位置顯示觸控面板10之表面的影像，即藉由第一鏡體23與第二鏡體25顯示不同位置之第一觸控影像與第二觸控影像，以供偵測模組30擷取到不同位置之第一觸控影像與第二觸控影像，如此影像處理器即可依據偵測模組30所擷取到之第一觸控影像與第二觸控影像，而計算出第一觸控影像與第二觸控影像中之黑影的所在位置，以得知指示器壓觸觸控面板10之座標，並將觸控座標傳送至系統主機，以供系統主機執行對應之系統功能。
本發明之位置偵測裝置僅具有單一偵測模組30與第一鏡體23和第二鏡體25，即可擷取到觸控面板10之表面的不同位置之觸控影像，所以結構簡單，可降低成本。此外，因偵測模組30之影像感測器36是以橫躺之方式而相對於第一平面鏡34與第二平面鏡35，即影像感測器36平行於觸控面板10之表面，而不需以直立方式設置於觸控面板10，所以可有效降低觸控面板10之整體厚度。
第四圖僅為本發明之一實施例，並不限定本發明之實施方式僅為第四圖實施方式。若不考量觸控面板10之整體厚度下，影像感測器36可採用站立之方式設置於觸控面板10，即影像感測器36與觸控面板10之表面呈垂直。此外，本發明亦可不需要設置板體32，而直接將第一平面鏡34與第二平面鏡35設置於觸控面板10，而影像感測器36設置於第一平面鏡34與第二平面鏡35之下方。
復參閱第四圖，本發明之偵測模組30更包含有一鏡頭38，其設置於板體32之下方，而位於第一平面鏡34與第二平面鏡35之下方，而影像感測器36則設置於鏡頭38之下方。鏡頭38用於調整影像感測器36擷取第一平面鏡34與第二平面鏡35所顯示之第一觸控影像與第二觸控影像的焦距，以讓影像感測器36可清晰擷取到第一平面鏡34與第二平面鏡35所顯示之第一觸控影像與第二觸控影像。鏡頭38係設置於一鏡頭殼體39內，而可上下移動以調整焦距。
請參閱第五圖，係本發明之一較佳實施例之位置偵測裝的固定殼體與框架的立體圖。如圖所示，本發明更包含一框架22與至少一固定殼體24，框架22設置於觸控面板10（參閱第一圖與第二圖），而位於觸控面板10之邊緣。固定殼體24設置於框架22，以用於固定光傳輸元件21於觸控面板10之邊緣。固定殼體24呈半圓形，以固定光傳輸元件21，而可以供光線照射於顯示面板10之表面。此外，固定殼體24之材質可為白色材料，以將背面光集中於觸控面板10之表面。另外，框架22與固定殼體24可為一體成形。本發明亦可不需設置框架22於觸控面板10，而直接將固定殼體24設置於觸控面板10之邊緣，以固定光傳輸元件21。
請參閱第六圖，係本發明之一較佳實施例之位置偵測裝置的固定殼體與固定座的立體圖。如圖所示，本發明更包含一固定座26與兩連接管27，連接管27設置於固定座26之一側並連接固定殼體24（參閱第五圖），固定座26用於固定光源20（參閱第一圖）。此實施例運用於第一圖採用兩個光源20之方式，第一圖之光傳輸元件21係插入於連接管27，而固定於固定殼體24。光源20固定於固定座26而產生光線，光線經由固定座26之側面照射於位於連接管27之光傳輸元件21，光傳輸元件21即傳輸光線，而使得光線均勻照射於觸控面板10之表面。
請參閱第七圖，係本發明之另一較佳實施例之位置偵測裝置的固定殼體與固定座的立體圖。此實施例係運用於第二圖採用四個光源20之方式。如圖所示，固定座28之一側面僅設有一連接管29，光源20固定於固定座28，而第二圖之光傳輸元件21係插入於連接管29。
綜上所述，本發明觸控面板之具單一偵測模組的位置偵測裝置，其包含光源、第一鏡體、第二鏡體與偵測模組，光源用於產生光線而照射於觸控面板之表面，第一鏡體與第二鏡體分別設置於觸控面板之邊緣的兩端，以顯示觸控面板之表面的第一觸控影像與第二觸控影像，偵測模組設置於觸控面板之邊緣並位於第一鏡體與第二鏡體之間，以擷取第一鏡體與第二鏡體所顯示之第一觸控影像與第二觸控影像，如此即可擷取不同位置之第一鏡體與第二鏡體所顯示之第一觸控影像與第二觸控影像，而依據第一觸控影像與第二觸控影像，得知指示器壓觸面板之座標。由於，本發明之偵測裝置僅需單一偵測模組，且結構簡單，如此，即可達到降低成本、減少厚度之目的。

惟以上所述者，僅為本發明一較佳實施例而已，並非用來限定本發明實施之範圍，故舉凡依本發明申請專利範圍所述之形狀、構造、特徵及精神所為之均等變化與修飾，均應包括於本發明之申請專利範圍內。
