本發明係關於一種控制系統，尤指一種觸控模組之控制系統。The invention relates to a control system, in particular to a control system of a touch module.
隨著科技進步，個人數位助理(PDA)、行動電話、平板筆記型電腦等具有觸控式面板之電子裝置也越來越普及，市面上之觸控式面板依其設計原理可分為數大類，而其中最具代表性之觸控面板為電阻式觸控面板以及電容式觸控面板。With the advancement of technology, electronic devices with touch panels, such as personal digital assistants (PDAs), mobile phones, and tablet notebook computers, are becoming more and more popular. The touch panels on the market can be divided into several categories according to their design principles. The most representative touch panels are resistive touch panels and capacitive touch panels.
電阻式觸控面板是利用手指或任意之物體按壓面板表面，使面板內部之導電層產生電壓，進而偵測面板表面受按壓之位置；另一則為電容式觸控面板，係利用手指或任意之導電物體觸碰面板表面，並與面板導電層所形成之電場產生電容耦合，以吸收面板表面之微小電流，進而偵測面板表面受觸碰之位置。The resistive touch panel uses a finger or any object to press the surface of the panel to generate a voltage on the conductive layer inside the panel, thereby detecting the position of the panel surface being pressed; the other is a capacitive touch panel, using a finger or any of them. The conductive object touches the surface of the panel and is capacitively coupled with the electric field formed by the conductive layer of the panel to absorb a small current on the surface of the panel, thereby detecting the position of the panel surface being touched.
而早期不管是電容式觸控面板或是電阻式觸控面板皆僅能同時對單一觸碰點做偵測，但是隨著電子產品的發展，使用者對於多點式觸碰面板的需求也開始出現。而為了達成多點式觸碰的目標，市面上已經出現了多種解決的方式，例如中華民國發明專利公開第200917111號「多點輸入之電阻式觸控面板及其偵測方法」與第200915165號「能識別多次碰觸之電阻式觸控銀幕」分別提出了兩種用以實現同時偵測多個觸碰點之觸碰面板。In the early days, both capacitive touch panels and resistive touch panels can only detect single touch points at the same time. However, with the development of electronic products, users' demand for multi-touch panels has also begun. appear. In order to achieve the goal of multi-point touch, there have been many solutions in the market, such as the Republic of China Invention Patent Open No. 200917111 "Multi-point input resistance typeThe touch panel and its detection method and the "Resistance touch screen capable of recognizing multiple touches" of No. 200915165 respectively propose two touch panels for simultaneously detecting a plurality of touch points.
歸納上述兩種用以實現偵測多個觸碰點之觸碰面板之技術特徵，可以清楚發現，其主要是利用複數個導電區塊分別用以傳導觸控面板之部份區域之觸控感應訊號，而觸控面板之控制模組於接收到觸控感應訊號後，即可判斷出觸控感應訊號所對應之觸碰位置座標。Summarizing the technical features of the above two touch panels for detecting multiple touch points, it can be clearly found that the plurality of conductive blocks are respectively used to conduct touch sensing of a part of the touch panel. After receiving the touch sensing signal, the control panel of the touch panel can determine the touch position coordinate corresponding to the touch sensing signal.
請參閱第一圖，第一圖係為習知技術用於多點式觸控面板之控制系統示意圖。控制系統100係電性耦接於觸控模組200與電腦主機300，並包含控制處理模組11。控制處理模組11係藉由複數條傳輸路徑111電性連結於觸控模組200，並在觸控模組200被觸發後，經由這些傳輸路徑111中之至少一者接收至少一觸控感應訊號S1，並依據觸控感應訊號S1傳送觸碰綜合訊號S2至電腦主機300。Please refer to the first figure. The first figure is a schematic diagram of a control system for a multi-point touch panel according to the prior art. The control system 100 is electrically coupled to the touch module 200 and the computer host 300, and includes a control processing module 11. The control processing module 11 is electrically connected to the touch module 200 by a plurality of transmission paths 111, and after the touch module 200 is triggered, receives at least one touch sensing via at least one of the transmission paths 111. The signal S1 transmits the touch integrated signal S2 to the host computer 300 according to the touch sensing signal S1.
然而，由於控制處理模組11無法同時間接收所有傳輸路徑111之觸控感應訊號S1，因此，控制處理模組11必須依序對傳輸路徑111做接收觸控感應訊號S1之動作。舉例而言，若觸碰模組200具有四條傳輸路徑111a、111b、111c與111d，且傳輸路徑111a、111b、111c與111d係用以分別傳送觸控感應訊號S1a、S1b、S1c與S1d，則控制處理模組11於一個觸碰點判斷週期中，必須先對傳輸路徑111a做接收觸控感應訊號S1a之動作，並依序對傳輸路徑111b、111c與111d做接收觸控感應訊號S1b、S1c與S1d之動作。However, since the control processing module 11 cannot receive the touch sensing signals S1 of all the transmission paths 111 at the same time, the control processing module 11 must sequentially perform the operation of receiving the touch sensing signals S1 on the transmission path 111. For example, if the touch module 200 has four transmission paths 111a, 111b, 111c, and 111d, and the transmission paths 111a, 111b, 111c, and 111d are used to respectively transmit the touch sensing signals S1a, S1b, S1c, and S1d, Control processing module 11In a touch point determination period, the operation of receiving the touch sensing signal S1a must be performed on the transmission path 111a, and the operations of receiving the touch sensing signals S1b, S1c, and S1d are sequentially performed on the transmission paths 111b, 111c, and 111d.
但是，由於觸控面板通常僅有少數區域會受到使用者觸碰，因此在一個觸碰點判斷週期中，大部分的傳輸路徑111是不會有觸控感應訊號S1的，如此一來，控制處理模組11依序對傳輸路徑111做接收觸控感應訊號S1之動作會導致系統資源的浪費。However, since only a few areas of the touch panel are touched by the user, most of the transmission paths 111 do not have the touch sensing signal S1 during a touch point determination period, so that the control is performed. The processing module 11 sequentially receives the touch sensing signal S1 on the transmission path 111, which causes waste of system resources.
以上述中華民國發明專利公開第200917111號「多點輸入之電阻式觸控面板及其偵測方法」所揭露之觸控面板結構為例，若觸控模組200於第一方向配置有20條平面電阻，並於第二方向配置有15條平面電阻，以於觸控模組200上交錯形成300個相異之觸碰區域。如此一來，控制處理模組11於一個觸碰點判斷週期中即需要對電性連結於這35條平面電阻之傳輸路徑111依序做接收觸控感應訊號S1之動作。若於此觸碰點判斷週期中，第一方向與第二方向各僅有2條平面電阻受到觸碰，則所有35條傳輸路徑111中將僅有4條傳輸路徑111會傳送觸控感應訊號S1，如此一來，控制處理模組11於35次接收觸控感應訊號S1動作中將有31次接收動作無法取得觸控感應訊號S1，而導致系統資源的浪費。For example, the touch panel structure disclosed in the above-mentioned "Receiving Touch Panel of Multi-point Input and Detection Method" of the Chinese Patent Publication No. 200917111 is used as an example. If the touch module 200 is configured in the first direction, 20 The planar resistors are arranged with 15 planar resistors in the second direction to form 300 different touch regions on the touch module 200. In this way, the control processing module 11 needs to sequentially receive the touch sensing signal S1 in the transmission path 111 electrically connected to the 35 planar resistors in a touch point determination period. If only two planar resistances of the first direction and the second direction are touched during the touch point determination period, only four of the 35 transmission paths 111 will transmit the touch sensing signal. In this case, the control processing module 11 will not receive the touch sensing signal S1 in 31 receiving operations during the 35 times of receiving the touch sensing signal S1, resulting in waste of system resources.
綜觀以上所述，由於控制處理模組11於每一個觸碰點判斷週期中皆必須對所有傳輸路徑111依序做接收觸控感應訊號S1之動作，因此會導致系統資源的大幅浪費。Looking at the above, since the control processing module 11 judges each touch pointIn the off-cycle, all the transmission paths 111 must be sequentially received to receive the touch sensing signal S1, thus causing a large waste of system resources.
緣此，本發明之主要目的係提供一種控制系統，尤指一種觸控模組之控制系統。此控制系統於一個觸碰點判斷週期中係先利用一個觸碰偵測模組用以偵測傳輸路徑上是否有觸控感應訊號，並據以發送觸碰偵測訊號，而控制處理模組則根據觸碰偵測訊號對至少一傳輸路徑接收觸控感應訊號。Accordingly, the main object of the present invention is to provide a control system, and more particularly to a control system for a touch module. The control system first uses a touch detection module to detect whether there is a touch sensing signal on the transmission path during a touch point determination period, and sends a touch detection signal according to the control processing module. Receiving a touch sensing signal on at least one transmission path according to the touch detection signal.
一種觸控模組之控制系統係電性耦接於一觸控模組，並且包含複數個感應訊號切換開關、觸碰偵測模組以及控制處理模組。複數個感應訊號切換開關係藉由複數個第一電性傳輸路徑而分別電性連結於觸控模組，藉以接收並傳送出至少一觸控感應訊號；觸碰偵測模組係用以接收觸控感應訊號，並依據該觸控感應訊號儲存複數個觸控偵測資訊，據以發送出觸碰偵測訊號，其中觸控偵測訊號係為該等觸控偵測資訊之集合；控制處理模組在接收到觸碰偵測訊號後，即發送至少一切換訊號至感應訊號切換開關，並據以接收所對應之觸控感應訊號。The control system of the touch module is electrically coupled to a touch module, and includes a plurality of inductive signal switching switches, a touch detection module, and a control processing module. The plurality of sensing signals are electrically connected to the touch module by a plurality of first electrical transmission paths to receive and transmit at least one touch sensing signal; the touch detection module is configured to receive Touch sensing signal, and storing a plurality of touch detection information according to the touch sensing signal, thereby transmitting a touch detection signal, wherein the touch detection signal is a set of the touch detection information; After receiving the touch detection signal, the processing module sends at least one switching signal to the sensing signal switching switch, and receives the corresponding touch accordingly.Control the sensing signal.

The touch detection information is stored in the temporary storage space.

相較於習知之觸控模組之控制系統，本發明利用一觸碰偵測模組用以偵測傳輸路徑上是否有觸控感應訊號，故控制處理模組可僅針對有觸控感應訊號之傳輸路徑做接收動作，並因此節省大量的系統資源，避免系統做無謂的動作。Compared with the control system of the conventional touch module, the present invention utilizes a touch detection module for detecting whether there is a touch sensing signal on the transmission path, so the control processing module can only be used for the touch sensing signal. The transmission path performs the receiving action, and thus saves a lot of system resources, and prevents the system from doing unnecessary actions.
本發明所採用的具體實施例，將藉由以下之實施例及圖式作進一步之說明。The specific embodiments of the present invention will be further described by the following examples and drawings.
本發明係關於一種控制系統，尤指一種觸控模組之控制系統。以下茲列舉一較佳實施例以說明本發明，然熟習此項技藝者皆知此僅為一舉例，而並非用以限定發明本身。有關此較佳實施例之內容詳述如下。The invention relates to a control system, in particular to a control system of a touch module. The invention is illustrated by the following description of the preferred embodiments of the invention, and is not intended to limit the invention. relatedThe contents of this preferred embodiment are detailed below.
請參閱第二圖，第二圖係為本發明控制系統之較佳實施例示意圖。本較佳實施例之一種觸控模組之控制系統400係電性耦接於觸控模組200，並且包含複數個感應訊號切換開關41、觸碰偵測模組42以及控制處理模組43。Please refer to the second figure, which is a schematic diagram of a preferred embodiment of the control system of the present invention. The touch control module 400 of the preferred embodiment is electrically coupled to the touch module 200 and includes a plurality of inductive signal switching switches 41, a touch detection module 42 and a control processing module 43. .
感應訊號切換開關41係藉由複數個第一電性傳輸路徑411而分別電性連結於觸控模組200，並在觸控模組200被觸發後，經由上述第一電性傳輸路徑411中之至少一者接收並傳送出至少一觸控感應訊號S1。The sensing signal switching switch 41 is electrically connected to the touch module 200 by a plurality of first electrical transmission paths 411, and is triggered by the touch module 200 via the first electrical transmission path 411. At least one of the at least one receives and transmits at least one touch sensing signal S1.
觸碰偵測模組42係經由複數個對應於第一電性傳輸路徑411之第二電性傳輸路徑421而分別電性連結於感應訊號切換開關41，並用以經由第二電性傳輸路徑421中對應於上述傳送各觸控感應訊號S1之第一電性傳輸路411接收觸控感應訊號S1，據以發送出觸碰偵測訊號S3。The touch detection module 42 is electrically connected to the inductive signal switching switch 41 via a plurality of second electrical transmission paths 421 corresponding to the first electrical transmission path 411, and is used to pass through the second electrical transmission path 421. The first electrical transmission path 411 corresponding to the above-mentioned respective touch sensing signals S1 receives the touch sensing signal S1, and the touch detection signal S3 is sent accordingly.
控制處理模組43係電性連結於觸碰偵測模組42，並經由複數個對應於第一電性傳輸路徑411之第三電性傳輸路徑431而分別電性連結於感應訊號切換開關41。The control processing module 43 is electrically connected to the touch detection module 42 and electrically connected to the inductive signal switching switch 41 via a plurality of third electrical transmission paths 431 corresponding to the first electrical transmission path 411 . .
當控制處理模組43接收觸碰偵測訊號S3後，係依據觸碰偵測訊號S3而經由第三電性傳輸路徑431中對應於傳送觸控感應訊號S1之第一電性傳輸路411發送至少一切換訊號S4至所對應之感應訊號切換開關41，據以接收觸控感應訊號S1。When the control processing module 43 receives the touch detection signal S3, it is sent according to the touch detection signal S3 via the first electrical transmission path 411 corresponding to the transmission touch sensing signal S1 in the third electrical transmission path 431. At least one switching signal S4 to the corresponding inductive signal switching switch 41 for receiving the touch sensing signalS1.
此外，於本實施例中之較佳者，控制處理模組43係包含座標處理單元432，用以於控制處理模組43接收觸控感應信號S1後，判斷觸控感應信號S1所對應之觸碰位置座標。並且，於本實施例中之較佳者，控制處理模組43更可電性連結於電腦主機300，藉以依據觸控感應信號S1傳送觸碰綜合訊號S2至電腦主機300。In addition, in the preferred embodiment, the control processing module 43 includes a coordinate processing unit 432 for determining the touch corresponding to the touch sensing signal S1 after the control processing module 43 receives the touch sensing signal S1. Touch the position coordinates. In addition, in the preferred embodiment, the control processing module 43 is further electrically connected to the computer host 300, so that the touch integrated signal S2 is transmitted to the computer host 300 according to the touch sensing signal S1.
此外，觸碰偵測模組42更可以包含觸碰偵測暫存器422。請參閱第三圖，第三圖係為觸碰偵測暫存器422之示意圖。觸碰偵測暫存器422係具有複數個暫存空間reg，並用以依據觸控感應信號S1對應儲存觸碰偵測資訊於暫存空間reg內，而觸碰偵測訊號S3則可以為這些觸碰偵測資訊之集合。In addition, the touch detection module 42 may further include a touch detection register 422. Please refer to the third figure, which is a schematic diagram of the touch detection register 422. The touch detection register 422 has a plurality of temporary storage spaces reg, and is configured to store the touch detection information in the temporary storage space reg according to the touch sensing signal S1, and the touch detection signal S3 can be used for these Touch the collection of detection information.
舉例而言，若觸控模組200因受到觸碰而產生觸控感應信號S1a與S1b，則觸控感應信號S1a與S1b會分別經由第一電性傳輸路411a與411b、感應訊號切換開關41a與41b以及第二電性傳輸路徑421a與421b而傳送至觸碰偵測模組42，而觸碰偵測暫存器422則將觸控感應信號S1a與S1b所對應之暫存空間reg a與reg b內之觸碰偵測資訊紀錄為1，並將未接收到之觸控感應信號S1c與S1d所對應之暫存空間reg c與reg d內之觸碰偵測資訊紀錄為0。如此一來觸碰偵測暫存器422所紀錄之觸碰偵測資訊依序係為1100，而觸碰偵測模組42所發送之觸碰偵測訊號S3即可為1100。For example, if the touch sensing module S1a and S1b are generated by the touch module 200, the touch sensing signals S1a and S1b pass through the first electrical transmission paths 411a and 411b and the inductive signal switching switch 41a, respectively. And the 41b and the second electrical transmission paths 421a and 421b are transmitted to the touch detection module 42, and the touch detection register 422 connects the temporary storage space reg a corresponding to the touch sensing signals S1a and S1b. The touch detection information record in reg b is 1, and the touch detection information in the temporary storage spaces reg c and reg d corresponding to the untouched touch sensing signals S1c and S1d is recorded as 0. In this way, the touch detection information recorded by the touch detection register 422 is sequentially 1100, and the touch is touched.The touch detection signal S3 sent by the detection module 42 can be 1100.
而當控制處理模組43接收到觸碰偵測訊號S3後，即可經由第三電性傳輸路徑431a與431b傳送切換訊號S4a與S4b至感應訊號切換開關41a與41b，以使感應訊號切換開關41a與41b將觸控感應信號S1a與S1b傳送至控制處理模組43。When the control processing module 43 receives the touch detection signal S3, the switching signals S4a and S4b can be transmitted to the inductive signal switching switches 41a and 41b via the third electrical transmission paths 431a and 431b to enable the inductive signal switching switch. The touch sensing signals S1a and S1b are transmitted to the control processing module 43 by 41a and 41b.
為了讓本實施例之動作更為明確，下面係再提出另一舉例，若觸控模組200因受到觸碰而產生觸控感應信號S1c與S1d，則觸控感應信號S1c與S1d會分別經由第一電性傳輸路411c與411d、感應訊號切換開關41c與41d以及第二電性傳輸路徑421c與421d而傳送至觸碰偵測模組42，而觸碰偵測暫存器422則將觸控感應信號S1c與S1d所對應之暫存空間reg c與reg d內之觸碰偵測資訊紀錄為1，並將未接收到之觸控感應信號S1a與S1b所對應之暫存空間reg a與reg b內之觸碰偵測資訊紀錄為0。如此一來觸碰偵測暫存器422所紀錄之觸碰偵測資訊依序係為0011，而觸碰偵測模組42所發送之觸碰偵測訊號S3即可為0011。In order to make the operation of the embodiment more clear, another example is given below. If the touch sensing module 200 generates the touch sensing signals S1c and S1d due to the touch, the touch sensing signals S1c and S1d respectively pass through The first electrical transmission paths 411c and 411d, the inductive signal switching switches 41c and 41d, and the second electrical transmission paths 421c and 421d are transmitted to the touch detection module 42, and the touch detection register 422 is touched. The touch detection information records in the temporary storage spaces reg c and reg d corresponding to the control sensing signals S1c and S1d are 1, and the temporary storage space reg a corresponding to the touch sensing signals S1a and S1b that are not received are The touch detection information record in reg b is 0. In this way, the touch detection information recorded by the touch detection register 422 is sequentially 0011, and the touch detection signal S3 sent by the touch detection module 42 is 0011.
而當控制處理模組43接收到觸碰偵測訊號S3後，即可經由第三電性傳輸路徑431c與431d傳送切換訊號S4c與S4d至感應訊號切換開關41c與41d，以使感應訊號切換開關41c與41d將觸控感應信號S1c與S1d傳送至控制處理模組43。When the control processing module 43 receives the touch detection signal S3, the switching signals S4c and S4d can be transmitted to the inductive signal switching switches 41c and 41d via the third electrical transmission paths 431c and 431d to enable the inductive signal switching switch. The touch sensing signals S1c and S1d are transmitted to the control processing module 43 by 41c and 41d.
由以上舉例可以清楚知道，若觸控模組200總共具有35條平面電阻，且利用35條第一電性傳輸路411分別對應這些平面電阻以傳送觸控感應訊號S1，當觸控模組200受到觸發而發送4個觸控感應訊號S1時，經由觸碰偵測模組42先行偵測並據以發送觸碰偵測訊號S3後，控制處理模組43僅需依序發送4個切換訊號S4至上述4個觸控感應訊號S1所對應之感應訊號切換開關41，即可接收上述4個觸控感應訊號S1，換以言之，若控制處理模組43同一時間只能接收一個觸控感應訊號S1，則於一個觸碰點判斷週期中僅需要4次接收觸控感應訊號S1動作即可，而若控制處理模組43同一時間能夠接收二個觸控感應訊號S1，則於一個觸碰點判斷週期中僅需要2次接收觸控感應訊號S1動作，相較於習知技術之控制系統需要35次的接收動作，本發明之控制系統係可節省大量的系統資源。It can be clearly seen from the above examples that if the touch module 200 has a total of 35The stripe plane resistors are respectively used to transmit the touch sensing signals S1 by using the 35 first electrical transmission paths 411 respectively. When the touch module 200 is triggered to transmit the four touch sensing signals S1, the touch is performed. After the detection module 42 detects and sends the touch detection signal S3, the control processing module 43 only needs to sequentially send the four switching signals S4 to the sensing signal switching corresponding to the four touch sensing signals S1. The switch 41 can receive the four touch sensing signals S1. In other words, if the control processing module 43 can only receive one touch sensing signal S1 at the same time, only 4 is needed in one touch point judgment period. The receiving touch sensing signal S1 can be received once, and if the control processing module 43 can receive the two touch sensing signals S1 at the same time, only two touch sensing signals S1 are required to be received in one touch point determination period. Compared with the control system of the prior art, which requires 35 receiving actions, the control system of the present invention can save a lot of system resources.
綜觀以上所述，由於本發明利用觸碰偵測模組42用以偵測傳輸路徑上是否有觸控感應訊號S1，故控制處理模組43可僅針對有觸控感應訊號S1之傳輸路徑做接收動作，而因此節省大量的系統資源，避免系統做無謂的動作。In view of the above, since the touch detection module 42 is used to detect whether there is a touch sensing signal S1 on the transmission path, the control processing module 43 can only perform the transmission path with the touch sensing signal S1. Receive actions, thus saving a lot of system resources and avoiding unnecessary actions.
藉由以上較佳具體實施例之詳述，係希望能更加清楚描述本發明之特徵與精神，而並非以上述所揭露的較佳具體實施例來對本發明之範疇加以限制。相反地，其目的是希望能涵蓋各種改變及具相等性的安排於本發明所欲申請之專利範圍的範疇內。The features and spirit of the present invention will be more apparent from the detailed description of the preferred embodiments.
