五、新型說明： 【新型所屬之技術領域】 [0001] [0002] 本創作係為一種觸控螢幕裝置，尤指一種針對觸控 螢幕裝置的觸控面板執行電容值重新校正的觸控校正裝 置。 【先前技術】 隨著觸控技術不斷的精進與發展，觸控式的輸入裝 置已普遍應用在許多終端電子產品上，提供了更為優越 的操控性及多樣性的介面操作方式，藉以取代傳統滑鼠 及鍵盤等輸入裝置的功能，進而節省操作的空間並解決 周邊輸入設備攜帶不便的困擾。 觸控面板依據其觸控技術概分有電阻式、電容式、 光學式或聲波式等，而電容式觸控面板依照其工作原理 的不同又分為表面電容式及投射電容式兩種，其中投射 電容式觸控面板為目前市場中較受歡迎且市場佔有率較 高的技術，此由於投射式電容式觸控面板具有較佳的透 視率、較為靈敏的操作性、以及較高的使用壽命等優點 〇 投射電容式觸控面板的結構，主要是在一玻璃基板 上以透明導電物質以X軸及Y軸方向，形成一矩陣狀排列 的感應線路，並在每一個X軸及Y軸的感應線路交會處構 成一具有等效電場的感應點，當手指接近或碰觸此一感 應點時，則會在感應點處產生一電容值的變化，如此觸 控面板的微控制器即可經由偵測此一電容值產生變化的 位置，進而判斷及計算出手指所接近或碰觸處相對應在 表單編號A01.01 第3頁/共14頁 觸控面板上的座標點資料。 然而，投射電容式觸控面板的缺點在於該手指接近 或碰觸感應點時所產生的電容值改變量大小甚為微弱， 觸控面板又易於受到環境因素的影響而造成觸控面板靈 敏度的降低，該些影響因素包括溫度或周邊電磁雜訊的 干擾，造成觸控訊號不易被偵測及判讀，甚至會被誤判 為有進行觸控操作的缺點。 目前習知的解決方式則是在一已安裝有作業軟體的 終端電子產品上預載安裝一校準程式，當觸控面板靈敏 度降低而不易於操作時，得以藉由手指碰觸及點選顯示 在終端電子產品的螢幕桌面上的校準圖像，藉此執行校 準程式對電容基準值進行校正。再者，另一種習知的解 決方式則是採用自動校準的方式，以便能夠於在觸控面 板操作的期間中，藉由設定一固定的偵測週期執行偵測 ，並依據偵測結果判別觸控面板是否需要即時執行校準 程式。 前述揭露的習知的解決方式仍具有部分的缺點，其 中經由手指觸碰及點選螢幕桌面上校準圖像的方式，使 用者必須事先將層疊及顯示於桌面上的視窗逐一關閉或 移開後，才可觀視及碰觸到位於桌面上的校準圖像，藉 以執行校準程式，因此當觸碰面板的靈敏度實際上已不 甚佳的清況下，將造成使用者於觸控操作上的不便。再 者，藉由定時偵測及自動校準的方式，由於校準程式必 須在背景執行且不斷定時偵測及進行校準，不但將會耗 費終端電子產品的記憶體資源，亦相對會產生較多的耗 能而難以符合環保的要求。 表單編號A0101 第4頁/共14頁 M434992 [0004] 請參閱第1圖所示，為本創作的觸控螢幕袭置的外觀 示意圖。本創作的觸控螢幕裝.置i是以一體成形多功能觸 控電腦（All in One PC)為例進行說明，但本創作並不 以此為限，觸控螢幕裝置亦可指一具有觸控螢幕的筆記 型電腦或平板電腦。觸控螢幕裝置〗是由一觸控面板及一 顯不螢幕相互疊置所構成，在觸控面板的表面具有一提 供觸控操作區域的觸控區3及-非供觸控操作區域的非觸 控區2 ’當手指或導電體接近或觸碰觸控區3時可以產生 對應的一觸碰訊號，非觸碰區則設置有至少一功能鍵4 ，功能鍵4可以依據觸控螢幕裝置丨的結構而選擇以電容 式觸碰開關或機械式開關等其中任一種方式實施，使得 δ功旎鍵4被觸發後可以產生一控制訊號的輸出，以執 行一觸控校正功能。 以下再就功能鍵4的選擇做進一步的說明，當本創作 實施於-無邊框設計的觸控螢幕裝以時，即觸控營幕裝 置1的非觸控區2與觸控區3是構成在一體式設計的透明蓋 板上’例如全平面式設計的觸控式螢幕，在此-情況下 ’本創作可以選擇在非觸控區2的蓋板表面任—位置處設 置電容式觸碰開關’並在位於電容式觸碰開關的表面上 同㈣刷設置-識別性的圖案5，以供使用者易於賴及 碰觸操作。另者’當本創作為_具有邊框設計的觸控營 幕裝置1時，例如觸控式螢幕為具有一邊框的設計時，本 創作可選擇以機械式開關實施於非觸控區2的邊框任一位 置處以供職操作，並㈣在機械式開關的表面上印刷 設置識別性的圖案5。 請參閱第2圖所示’為本創作的觸控螢幕裝置的功能 表單編號A0101 第6頁/共14頁 =塊圖。如圖所示，觸控螢幕裝幻至少包括一中央處理 盗10、—顯示螢幕20、-觸控面板3〇' 一觸控處理樓= 、-觸控校正模組5〇及-儲存模㈣^前述的觸控處 理模組40、觸控校正模組5Q、儲麵細及顯示營幕^ 分別是電連接至巾央處理謂，以便於透過巾央處理器 1〇進订功能的控制及訊息的處理，觸控面板30則是電連 接至觸控處理模組40，並疊設於顯示螢幕2〇上。 觸控面板咖讀供觸控_的倾，當觸控面板 3(H貞測-觸碰動作後可以對應產生—觸控訊㈣，並輪 出至觸控處轉剛，駿處理模組侧⑽接收的觸 控訊號ΊΊ予以解析’經由計算得到—相對應的座標點資 訊，並傳輸至中央處理器1〇進行後續的處理，中央處理 器10則將處理後所得到的顯示資MD1傳遞至顯示螢幕2〇 ’並命令顯示螢幕20予以輸出顯示。 在本實施例中，觸控面板3〇主要是設置有一功能鍵 32，功能鍵32是與中央處理器1〇電連接，功能鍵32用以 提供操作者可以強制執行觸控面板3〇觸控校正的功能， 當功能鍵32被觸發後可產生一控制訊號S1，並輸出至中 央處理:器10，經中央處理器1〇判定為功能鍵32所發出的 控制訊號si時，中央處理器10將發出一命令訊息C1至觸 控校正模組50，要求觸控校正模組5〇執行一觸控校正程 序，以藉由觸控校正程序的執行，更新觸控面板3〇上所 具有的複數個感應點的電容基準值，藉此改善觸控面板 30因受到溫度或周邊電磁雜訊的干擾而造成靈敏度下降 的影響’而當觸控校正模組5〇執行完畢觸控校正程序後 ，將町相對應於各感應點產生出一校正值，該校正值將 表單煸號糾101 第7頁/共14頁 M434992 會被輸出儲存模組60予以儲存，以便於更新設定為新的 電容基準值。 在本實施例中，該觸控校正模組50可選擇以軟體或 硬體的其中一種方式實施，其中當選擇以軟體的方式實 施時，觸控校正模組50可以應用程式的形式預先安裝於 儲存模組60，而透過中央處理器10進行控制及執行。 在本實施例中的儲存模組60則可選擇以硬碟、SSD 固態硬碟、快閃記憶體及動態隨機記憶體等中的任一者 實施。 另請參閱第3圖所示，為本創作的觸控螢幕裝置的觸 控校正方法的流程圖。如圖所示，在步驟S1 01中，當功 能鍵被觸發後產生控制訊號輸出至中央處理器，中央處 理器將發出控制命令，要求觸控校正模組啟動一觸控校 正程序，以便於對觸控面板的電容值基準值進行校正， 並進入下一步驟S102。 在步驟102中，觸控校正模組將會先發出一訊息要求 在顯示螢幕上顯示一警示晝面的訊息，藉此警示及要求 操作者將其雙手或其他物體遠離於觸控面板的表面，藉 此避免人體的手指或其他物體上所攜帶的靜電荷影響觸 控校正程序執行的結果，並進入下一步驟S103。 在步驟S103中，判定警糸晝面的顯示時間是否已經 過一預設時間長度，例如預設的時間長度可以選擇7〜10 秒之範圍，當顯示時間達到預設時間則進入下一步驟 S104，否則回到上一步驟S102，如此藉以提供充裕的時 間供操作者可以確實觀視到上述警示畫面的訊息。 在步驟S104中，觸控校正模組開始執行觸控校正程 表單编號A0101 第8頁/共14頁 針對難岐上的複數感應點的電容值進行校正， 經校正^成後，則將依據每個感應點產生出新的一校正 值，並進入下—步驟S105。 在步驟SU)5中’經觸控校正程序所產生的校正值將 在此-步驟中暫存於錯存模組内，並進入下—步觀〇6 〇 在步驟S106中，本創作的校準方法具有—判斷機制 ’用以判斷觸控校正程序是Η複執行達到_預設的校 正-人數’ U取得彡次的校正值於後續進行批在本創 作的校準方法中所預設的校正次數最佳者至少為3次當 判斷結果已達到預設的校正次數，則進入下_步驟si〇7田 ，否則回到步騾S104重新再執行—次觸控校正程序。 在步驟Sl〇7中，將判別暫存的各校正值之間的差異 值是否超過一預設的門播值，如判別為是，代表觸控校 正程序的執行過程中可能有受到環境因素或人為誤觸的 影響，而造成當時的使用環境並非穩定，所經校正產生 的校正值將失真而不具有參考性，如此將回到步驟Si 〇4 重新再執行觸控校正程序，否則將進入下一步驟§1〇8。 在步驟Sl〇8中，選擇最後一次暫存的校正值做為更 新後的校正值，並進行儲存及更新，以做為下—次觸控 操作時的電容基準值。 藉由上述可知，本創作由於是將觸控校正程式的執 行改成由觸發設置於觸控面板上的功能鍵來強制執行， 如此當觸控面板的觸控莖敏度不佳時，可以避免造成觸 控校正程序不易於被執行的缺點，且執行過程中也不會 受到桌面上各種已開啟視窗阻擋的影響。 表單編號_ A0101 第9 1/共14頁 M434992 綜上所陳，僅為本創作之較佳實施例而已，並非用 以限定本創作；凡其他未脫離本創作所揭示之精神下而 完成的等效修飾或置換，均應包含於後述申請專利範圍 内。 【圖式簡單說明】 [0005] 第1圖為本創作的觸控螢幕裝置的外觀示意圖。 第2圖為本創作的觸控螢幕裝置的功能方塊圖。 第3圖為本創作的觸控螢幕裝置的觸控校正方法的流程圖 〇 【主要元件符號說明】 [0006] 1觸控螢幕裝置 2非觸控區 3觸控區 4功能鍵 5圖像 10中央處理器 20顯示螢幕 30觸控面板 32功能鍵 40觸控處理模組 50觸控校正模組 6 0儲存模組 S101〜S108觸控校正方法的流程圖 表單編號A0101 第10頁/共14頁V. New Description: [New Technology Field] [0001] [0002] This is a touch screen device, especially a touch correction device that performs capacitance value recalibration for a touch panel of a touch screen device. . [Prior Art] With the continuous improvement and development of touch technology, touch input devices have been widely used in many terminal electronic products, providing superior controllability and a variety of interface operations to replace the traditional The functions of the input device such as the mouse and the keyboard further save the operation space and solve the problem of inconvenience of the peripheral input device. According to the touch technology, the touch panel has resistance, capacitance, optical or acoustic wave, and the capacitive touch panel is divided into surface capacitive type and projected capacitive type according to different working principles. Projected capacitive touch panels are currently popular in the market and have a high market share. This is because the projected capacitive touch panel has better perspective, more sensitive operation, and higher service life. The advantages of the projected capacitive touch panel are mainly to form a matrix-shaped sensing line with a transparent conductive material in a X-axis and a Y-axis direction on a glass substrate, and in each of the X-axis and the Y-axis. The intersection of the sensing line forms a sensing point with an equivalent electric field. When the finger approaches or touches the sensing point, a change in the capacitance value is generated at the sensing point, so that the touch panel microcontroller can be Detecting the position where the capacitance value changes, and then judging and calculating the coordinates of the touch panel corresponding to the touch panel corresponding to the form number A01.01 3/14 Information. However, the disadvantage of the projected capacitive touch panel is that the amount of change in the capacitance value generated when the finger approaches or touches the sensing point is weak, and the touch panel is susceptible to environmental factors, thereby reducing the sensitivity of the touch panel. These influencing factors include temperature or interference from surrounding electromagnetic noise, which makes the touch signal difficult to be detected and interpreted, and may even be misjudged as having the disadvantage of performing touch operation. At present, the conventional solution is to preload and install a calibration program on a terminal electronic product on which the operating software is installed. When the sensitivity of the touch panel is lowered and it is not easy to operate, it can be displayed on the terminal by finger touch and click. The calibration image on the screen of the electronic product is used to perform a calibration routine to correct the capacitance reference value. Moreover, another conventional solution is to adopt an automatic calibration method, so that during the operation of the touch panel, the detection is performed by setting a fixed detection period, and the touch is determined according to the detection result. Whether the control panel needs to execute the calibration program on the fly. The conventional solution disclosed above still has some disadvantages, in which the user must first close or remove the windows stacked and displayed on the desktop one by one by touching and clicking the image on the screen desktop. In order to view and touch the calibration image on the desktop, the calibration program can be executed. Therefore, when the sensitivity of the touch panel is actually not good, the user's inconvenience in touch operation will be caused. . Furthermore, with timing detection and automatic calibration, since the calibration program must be executed in the background and continuously detected and calibrated, not only will the memory resources of the terminal electronic products be consumed, but also the consumption will be relatively high. It is difficult to meet the requirements of environmental protection. Form No. A0101 Page 4 of 14 M434992 [0004] Please refer to Figure 1 for a schematic view of the appearance of the touch screen. The touch screen device of the present invention is described by taking an all-in-one multi-touch computer (All in One PC) as an example, but the creation is not limited thereto, and the touch screen device can also refer to a touch. Controlled screen notebook or tablet. The touch screen device is composed of a touch panel and a display screen. The touch panel has a touch area 3 for providing a touch operation area and a non-touch operation area. The touch area 2' can generate a corresponding touch signal when the finger or the conductive body approaches or touches the touch area 3, and the non-touch area is provided with at least one function key 4, and the function key 4 can be according to the touch screen device. The structure of the crucible is selected to be implemented by any one of a capacitive touch switch or a mechanical switch, so that the output of the control signal can be generated after the delta function key 4 is triggered to perform a touch correction function. In the following, the selection of the function key 4 is further explained. When the present invention is implemented in the touch screen without the frame design, the non-touch area 2 and the touch area 3 of the touch screen device 1 are configured. In the one-piece design of the transparent cover, such as a full-screen design of the touch screen, in this case, the author can choose to set a capacitive touch at the position of the cover surface of the non-touch area 2 The switch 'and is disposed on the surface of the capacitive touch switch with the (4) brush-identifying pattern 5 for the user to easily touch and touch. In addition, when the present invention is a touch screen device 1 having a bezel design, for example, when the touch screen is designed with a bezel, the present invention can select a frame that is implemented in the non-touch area 2 by a mechanical switch. The service operation is performed at any position, and (4) an identification pattern 5 is printed on the surface of the mechanical switch. Please refer to Figure 2 for the function of the touch screen device of this creation. Form No. A0101 Page 6 of 14 = Block Diagram. As shown in the figure, the touch screen installation includes at least one central processing pirate 10, a display screen 20, a touch panel 3 〇 'a touch processing floor =, a touch correction module 5 〇 and a storage module (4) The touch control module 40, the touch correction module 5Q, the storage surface and the display screen are respectively electrically connected to the towel processing, so as to facilitate the control of the ordering function through the towel processor 1 For the processing of the message, the touch panel 30 is electrically connected to the touch processing module 40 and stacked on the display screen 2 . The touch panel is read for the touch _, when the touch panel 3 (H 贞 - - touch action can be correspondingly generated - touch (4), and turn to the touch to turn just, the processing module side (10) The received touch signal is parsed and 'corresponding to the corresponding coordinate point information, and transmitted to the central processing unit 1 for subsequent processing, and the central processing unit 10 transmits the processed display resource MD1 to In the embodiment, the touch panel 3 is mainly provided with a function key 32. The function key 32 is electrically connected to the central processing unit 1 , and the function key 32 is used for the function key 32. To provide the operator with the function of forcing the touch panel 3 touch correction, when the function key 32 is triggered, a control signal S1 can be generated and output to the central processing unit 10, which is determined by the central processing unit 1 as a function. When the control signal si is issued by the key 32, the central processing unit 10 sends a command message C1 to the touch correction module 50, and the touch correction module 5 is required to execute a touch correction program to perform the touch correction program. Execution The capacitance reference value of the plurality of sensing points on the panel 3 is used to improve the sensitivity of the touch panel 30 due to the interference of temperature or surrounding electromagnetic noise, and is performed by the touch correction module 5 After the touch calibration process is completed, the correction value is generated corresponding to each sensing point, and the correction value will be stored in the output storage module 60 by the form number correction 101 page/14 pages M434992, so as to facilitate The update is set to a new capacitance reference value. In this embodiment, the touch correction module 50 can be implemented in one of a software or a hardware manner, wherein when the software module is selected to be implemented in a software manner, the touch correction module The application module 60 can be pre-installed in the storage module 60 and controlled and executed by the central processing unit 10. In the embodiment, the storage module 60 can be selected as a hard disk, an SSD solid state hard disk, or a flash memory. The implementation of any of the body and the dynamic random memory, etc. See also FIG. 3, which is a flow chart of the touch correction method of the touch screen device of the present invention. As shown in the figure, in step S1 01 When the function key is triggered, the control signal is output to the central processing unit, and the central processing unit issues a control command, and the touch correction module is required to start a touch correction program to correct the capacitance value reference value of the touch panel. And proceeding to the next step S102. In step 102, the touch correction module will first send a message requesting to display a warning message on the display screen, thereby alerting and requesting the operator to put their hands or other The object is away from the surface of the touch panel, thereby preventing the static charge carried on the finger or other object of the human body from affecting the result of the touch correction program, and proceeds to the next step S103. In step S103, determining the alert surface Whether the display time has passed a preset time length, for example, the preset time length can select a range of 7 to 10 seconds. When the display time reaches the preset time, the process proceeds to the next step S104, otherwise, the process returns to the previous step S102. In order to provide sufficient time for the operator to actually view the message of the above warning screen. In step S104, the touch correction module starts to perform the touch correction process form number A0101, page 8 / total 14 pages, and corrects the capacitance value of the complex sensing point on the difficult one. Each sensing point generates a new correction value and proceeds to the next step S105. In step SU) 5, the correction value generated by the touch correction program will be temporarily stored in the error module in this step, and enter the next step. In step S106, the calibration of the creation is performed. The method has a "judgment mechanism" for determining that the touch correction program is 执行 执行 达到 _ 预设 预设 预设 预设 预设 U U U U U U U U U U U U U U U U U U U U U U U U U U U The best one is at least 3 times. When the judgment result has reached the preset number of corrections, the process proceeds to the next step s7, otherwise the process returns to step S104 to perform the touch correction process again. In step S17, it is determined whether the difference value between the temporarily stored correction values exceeds a preset homing value. If the determination is yes, it may be subject to environmental factors during the execution of the touch correction program. Or the effect of human error, and the use environment at that time is not stable. The correction value generated by the correction will be distorted and not referenced. So I will return to step Si 〇4 to re-execute the touch calibration procedure, otherwise it will enter The next step is §1〇8. In step S1, the last temporary correction value is selected as the updated correction value, and stored and updated as the capacitance reference value in the next touch operation. As can be seen from the above, the present invention is implemented by changing the execution of the touch correction program to a function key triggered by the touch panel, so that when the touch panel of the touch panel is not sensitive, it can be avoided. The shortcomings of the touch correction program are not easy to be executed, and the execution process is not affected by the various open windows blocked on the desktop.
