Description
本發明係有關於一種觸控面板的掃描方法，其係尤指一種應用於觸控面板之增加掃描速度的掃描方法。 The present invention relates to a scanning method for a touch panel, and more particularly to a scanning method for increasing the scanning speed applied to the touch panel.
按，近年來，各式電子產品都不斷朝向操作簡便、小體積以及大螢幕尺寸的方向邁進，特別是攜帶式的電子產品對於體積及螢幕尺寸的要求更為嚴格。因此，許多電子產品都將觸控面板與液晶顯示面板整合，以省略鍵盤或是操控按鍵所需的空間，進而使螢幕可配置的面積擴大，並且使用者只要使用手指或觸控筆輕壓觸控面板，即可進行與電子裝置間之訊息傳輸。 In recent years, various electronic products have been moving toward simple operation, small size, and large screen size. In particular, portable electronic products have stricter requirements on volume and screen size. Therefore, many electronic products integrate the touch panel with the liquid crystal display panel to omit the space required for the keyboard or the control buttons, thereby expanding the configurable area of the screen, and the user simply taps the finger or the stylus. The control panel can perform message transmission with the electronic device.
請參閱第一圖，係為習知技術之觸控面板的結構示意圖。如圖所示，一般觸控面板包含一掃描匯流排10’、一偵測匯流排20’與一控制單元30’。掃描匯流排10’係耦接複數掃描線12’，該些掃描線12’設置於觸控面板之上板，偵測匯流排20’係耦接複數偵測線22’，該些偵測線22’係設置於觸控面板之下板，即位於該些掃描線12’之下方，並該些掃描線12’係交錯於該些偵測線22’，控制單元30’耦接掃描匯流排10’與偵測匯流排20’，以控制掃描匯流排10’與偵測匯流排20’而得知觸控面板上之複數觸碰點。 Please refer to the first figure, which is a structural diagram of a touch panel of the prior art. As shown, the general touch panel includes a scan busbar 10', a detection busbar 20', and a control unit 30'. The scanning busbar 10' is coupled to the plurality of scanning lines 12'. The scanning wires 12' are disposed on the upper surface of the touch panel, and the detecting busbars 20' are coupled to the plurality of detecting lines 22'. The control unit 30' is coupled to the scan busbar 12', and is located below the scan line 12', and the scan lines 12' are interleaved with the detection lines 22'.

As shown in the figure, in the scanning method for detecting a touch point, the control unit 30' drives the scan bus 10' to generate a scan signal V col and sequentially transmits the scan signal V col to the scans. The line 12', and when the scanning bus 10' transmits the scanning signal V col to each of the scanning lines 12', the control unit 30' drives the detecting bus 20' to sequentially scan the scanning signal V col Each detection line 22' of the 12' detects, that is, the control unit 30' detects each of the interlaced points of the matrix formed by the scan lines 12' and the detection lines 22'. However, because this scanning method is bound to detect each detection point in the touch panel, when the touch panel is too large, it takes too much time, so that the scanning frequency cannot be improved.

Touch panel, capacitive touch panel or projection touch panel.
請一併參閱第四圖，係為本發明之一較佳實施例之流程圖。如圖所示，本發明之應用於觸控面板之增加掃描速度的掃描方法之步驟係先執行步驟S10偵測觸控面板1，而得知至少一觸控區域，即控制單元30係透過第一掃描/偵測匯流排10與第二掃描/偵測匯流排20產生掃描訊號與偵測訊號至第一掃描/偵測線12與第二掃描/偵測線22，而偵測觸控面板1，以得知至少一觸控區域，之後會針對上述之偵測方法提供數個實施例，故於此先不加以贊述。 Please refer to the fourth figure, which is a flowchart of a preferred embodiment of the present invention. As shown in the figure, the step of the scanning method for increasing the scanning speed of the touch panel of the present invention is to perform the step S10 to detect the touch panel 1 and learn at least one touch area, that is, the control unit 30 transmits the first A scanning/detecting bus 10 and a second scanning/detecting bus 20 generate scanning signals and detection signals to the first scanning/detecting line 12 and the second scanning/detecting line 22, and detecting the touch panel 1, to know at least one touch area, and then provide several embodiments for the above detection method, so it will not be mentioned here first.
接上所述，執行步驟S12偵測該觸控區域，以得知觸控區域之至少一觸控點，即由於經過步驟S10所偵測觸控面板1而得知的觸控區域可能會包含鬼點或是實際上並未觸碰的觸控點，所以，本發明之步驟S12係針對觸控區域進行偵測，以找出觸控區域中之實際的觸控點。如此，本發明係藉由偵測觸控面板的觸控區域，再偵測觸控區域，以找出實際之觸控點，以達到提升觸控面板的掃描速度，並且本發明藉由偵測觸控區域中之每一偵測點，以避免產生鬼點，進而達到提升觸控面板的效率。 In the above, the touch area is detected in step S12 to learn at least one touch point of the touch area, that is, the touch area obtained by the touch panel 1 detected in step S10 may include The ghost point or the touch point that is not actually touched. Therefore, the step S12 of the present invention detects the touch area to find the actual touch point in the touch area. Therefore, the present invention detects the touch area of the touch panel and detects the touch area to find the actual touch point to improve the scanning speed of the touch panel, and the present invention detects the touch panel. Each detection point in the touch area avoids ghost points, thereby improving the efficiency of the touch panel.
請一併參閱第五A圖與第五B圖，係為本發明之一較佳實施例之得 知觸控區域的動作示意圖。如圖所示，本實施例為第四圖步驟S10偵測觸控面板1而得知至少一觸控區域的一個實施態樣，其偵測觸控面板1係先由控制單元30透過第一掃描/偵測匯流排10依序傳送一第一掃描訊號至觸控面板1之複數第一掃描/偵測線12，以偵測觸控面板1，而得知一第一參考區域14(如第五A圖所示)，接著控制單元30透過第一掃描/偵測匯流排10傳送複數第二掃描訊號至觸控面板1之該些第一掃描/偵測線12，以偵測觸控面板1，而得知一第二參考區域24(如第五B圖所示)，之後，控制單元30再依據第一參考區域14與第二參考區域24，而產生觸控區域。 Please refer to FIG. 5A and FIG. 5B together for the preferred embodiment of the present invention. Know the action diagram of the touch area. As shown in the figure, in this embodiment, the touch panel 1 is detected in step S10 of the fourth embodiment, and an embodiment of the at least one touch area is obtained. The touch panel 1 is first transmitted by the control unit 30. The scan/detection bus 10 sequentially transmits a first scan signal to the plurality of first scan/detection lines 12 of the touch panel 1 to detect the touch panel 1 and learn a first reference area 14 (eg, The first scanning/detecting bus 10 transmits the plurality of second scanning signals to the first scanning/detecting lines 12 of the touch panel 1 to detect the touch. The panel 1 is informed of a second reference area 24 (as shown in FIG. 5B). Thereafter, the control unit 30 generates a touch area according to the first reference area 14 and the second reference area 24.
再者，上述之控制單元30透過第一掃描/偵測匯流排10依序傳送第一掃描訊號至觸控面板1之複數第一掃描/偵測線12，以偵測觸控面板1而得知第一參考區域14中，控制單元30係於依序傳送第一掃描訊號至觸控面板1之該些第一掃描/偵測線12時，觸控面板1之複數第二掃描/偵測線22偵測位於該些第一掃描/偵測線12之一的觸控點而產生一第一偵測訊號，並傳送至觸控面板1之控制單元30，以得知第一參考區域14(如第五A圖所示)。 In addition, the control unit 30 sequentially transmits the first scan signal to the plurality of first scan/detection lines 12 of the touch panel 1 through the first scan/detection bus 10 to detect the touch panel 1 . In the first reference area 14 , the control unit 30 is configured to sequentially transmit the first scan signal to the first scan/detection lines 12 of the touch panel 1 , and the second scan/detection of the touch panel 1 The line 22 detects a touch point located on one of the first scan/detection lines 12 to generate a first detection signal, and transmits the first detection signal to the control unit 30 of the touch panel 1 to learn the first reference area 14 (as shown in Figure 5A).
同理，當控制單元30於傳送該些第二掃描訊號至觸控面板1之該些第一掃描/偵測線12時，觸控面板1之一偵測線係偵測位於觸控面板1之該些第二掃描/偵測線22之一的觸控點，而產生一第二偵測訊號，並傳送至觸控面板1之控制單元30，以得知第二參考區域24(如第五B圖所示)。上述之偵測觸控區域的方法係為一般X+Y掃描的方法，此為該技術領域中具有通常知識者所皆知的技術，故於此不再加以贊述。 Similarly, when the control unit 30 transmits the second scan signals to the first scan/detection lines 12 of the touch panel 1 , one of the touch panels 1 detects the line detection on the touch panel 1 A second detection signal is generated by the touch point of the second scan/detection line 22, and is transmitted to the control unit 30 of the touch panel 1 to learn the second reference area 24 (eg, Figure 5B shows). The above method for detecting the touch area is a general X+Y scanning method, which is a technique well known to those skilled in the art, and therefore will not be mentioned here.
請一併參閱第六A圖與第六B圖，係為本發明之另一較佳實施例之 得知觸控區域的動作示意圖。如圖所示，本實施例為第四圖步驟S10偵測觸控面板1而得知至少一觸控區域的另一個實施態樣，其偵測觸控面板1係先由控制單元30依序傳送第一掃描訊號至觸控面板1之該些第一掃描/偵測線12，以偵測觸控面板1而得知第一參考區域14，接著，控制單元30係依序傳送第二掃描訊號至觸控面板1之該些第二掃描/偵測線22，以偵測觸控面板1而得知第二參考區域24，之後，控制單元30再依據第一參考區域14與第二參考區域24，而得知觸控區域。 Please refer to FIG. 6A and FIG. 6B together for another preferred embodiment of the present invention. Know the action diagram of the touch area. As shown in the figure, in the fourth embodiment, the touch panel 1 is detected in the fourth step S10, and another embodiment of the at least one touch area is obtained. The touch panel 1 is detected by the control unit 30 in sequence. Transmitting the first scan signal to the first scan/detection lines 12 of the touch panel 1 to detect the touch panel 1 and learning the first reference area 14. Then, the control unit 30 sequentially transmits the second scan. Signaling to the second scanning/detecting lines 22 of the touch panel 1 to detect the touch panel 1 to learn the second reference area 24, and then the control unit 30 according to the first reference area 14 and the second reference Area 24, and the touch area is known.
承上所述，上述之控制單元30於第一掃描訊號至該些第一掃描/偵測線12之一時，該些第二掃描/偵測線22偵測位於第一掃描/偵測線12之觸控點，而產生第一偵測訊號，並傳送第一偵測訊號至控制單元30，使控制單元30得知第一參考區域14。同理，控制單元30於傳送第二掃描訊號至該些第二掃描/偵測線22之一時，該些第一掃描/偵測線12偵測位於第二掃描/偵測線22之觸控點，而產生第二偵測訊號，並傳送第二偵測訊號至控制單元30，使控制單元30得知第二參考區域24。 The second scanning/detecting line 22 detects the first scanning/detecting line 12 when the control unit 30 detects the first scanning signal to one of the first scanning/detecting lines 12. The first detection signal is generated by the touch point, and the first detection signal is transmitted to the control unit 30, so that the control unit 30 knows the first reference area 14. Similarly, when the control unit 30 transmits the second scan signal to one of the second scan/detection lines 22, the first scan/detection lines 12 detect the touch located on the second scan/detection line 22. And generating a second detection signal, and transmitting a second detection signal to the control unit 30, so that the control unit 30 knows the second reference area 24.
請一併參閱第七圖，係為本發明之一較佳實施例之觸控面板包含觸控區域的示意圖。如圖所示，本實施例在經過第二圖步驟S10偵測觸控面板1而得知至少一觸控區域後，產生四個觸控區域，分別為一第一觸控區域A1、一第二觸控區域A2、一第三觸控區域A3與一第四觸控區域A4。由於經過步驟S10所偵測觸控面板1而得知的觸控區域可能會包含鬼點或是實際上並未觸碰的觸控點，於此實施例中，第二觸控區域A2與第四觸控區域A4即為鬼點或是實際上並未觸碰的觸控點，所以，本發明才需要再針對該些觸控區 域進行偵測，以排除鬼點或是實際上並未觸碰的觸控點，進而達到提升觸控面板的效率。 Please refer to the seventh figure, which is a schematic diagram of a touch panel including a touch area according to a preferred embodiment of the present invention. As shown in the figure, after the touch panel 1 is detected in the second step S10 to learn at least one touch area, four touch areas are generated, which are respectively a first touch area A 1 and a The second touch area A 2 , the third touch area A 3 and the fourth touch area A 4 . The touch area obtained by the touch panel 1 detected in step S10 may include a ghost point or a touch point that is not actually touched. In this embodiment, the second touch area A 2 and The fourth touch area A 4 is a ghost point or a touch point that is not actually touched. Therefore, the present invention needs to detect the touch areas to exclude ghost points or actually Touch points that are not touched, thereby improving the efficiency of the touch panel.
請一併參閱第八圖，係為本發明之一較佳實施例之得知觸控點的動作示意圖。如圖所示，本實施例為第四圖步驟S12偵測觸控區域，以得知觸控區域之至少一觸控點的一個實施態樣，其偵測觸控區域的方法係由控制單元30係透過第一掃描/偵測匯流排10依序傳送一第三掃描訊號至觸控面板1之該些第一掃描/偵測線12，同時，控制單元30透過第二掃描/偵測匯流排20對應第三掃描訊號而偵測觸控區域，而產生一第三偵測訊號，並透過觸控面板之第二掃描/偵測線22傳送第三偵測訊號至控制單元30，使控制單元30得知觸控區域之至少一觸控點。 Please refer to the eighth figure, which is a schematic diagram of the action of the touch point according to a preferred embodiment of the present invention. As shown in the figure, in this embodiment, the touch area is detected in step S12 of the fourth step to learn an implementation manner of at least one touch point of the touch area, and the method for detecting the touch area is controlled by the control unit. The third scanning signal is transmitted to the first scanning/detecting lines 12 of the touch panel 1 through the first scanning/detecting bus 10, and the control unit 30 transmits the second scanning/detecting current. The row 20 detects the touch area corresponding to the third scan signal, generates a third detection signal, and transmits the third detection signal to the control unit 30 through the second scan/detection line 22 of the touch panel to control The unit 30 knows at least one touch point of the touch area.
此外，由於第八圖之偵測方法，係對觸控區域之每一偵測點進行偵測，以找出觸控點，然而，當觸控區域的範圍很大(含真實觸控點與鬼點)時，控制單元30在掃描偵測觸控面板將會很耗費掃描的時間，因此，本發明可在找出觸控區域之後，使用特定的形狀去偵測觸控區域，以確定該些觸控區域是否真實被觸控，如第九A圖至第九F圖所示，係為本發明之一較佳實施例之得知觸控點的動作示意圖。其控制單元30係偵測觸控區域的方法係分別為一中心掃描(Center test)、一角落掃描(Corner test)、一對角線掃描(Diagonal test)、一雙對角線掃描(Dual diagonal test)、一十字線掃描(Cross rest)或一棋盤掃描(checkboard test)，由於該些掃描方法不需要針對觸控區域中的每一偵測點進行偵測，因此，可以增加其掃描速度，並且上述之該些掃描方法為該技術領域中具有通常知識者所皆知的技術，故在此不再加以贊述 。 In addition, since the detection method of the eighth figure detects each detection point of the touch area to find the touch point, however, when the range of the touch area is large (including the real touch point and When the control unit 30 scans and detects the touch panel, it will take a long time to scan. Therefore, after the touch area is found, the present invention can use a specific shape to detect the touch area to determine the Whether the touch areas are actually touched, as shown in FIGS. 9A to 9F, is a schematic diagram of the action of the touch points according to a preferred embodiment of the present invention. The method for detecting the touch area by the control unit 30 is a center test, a corner test, a diagonal scan, and a diagonal scan. Test), a cross rest or a checkboard test. Since the scanning methods do not need to detect each detection point in the touch area, the scanning speed can be increased. And the scanning methods mentioned above are well-known technologies in the technical field, and therefore are not mentioned here. .
