Description
本新型是有關於一種觸控裝置，且特別是有關於一種紅外線觸控裝置。 The present invention relates to a touch device, and more particularly to an infrared touch device.
觸控螢幕按感測器工作原理，大致上可分為電容式、電阻式、紅外線式、聲波式與影像處理式。紅外線式觸控螢幕是利用收發紅外線的二極體，形成可被遮斷的光柵，以遮斷信號作為操作點定位。 Touch screens can be divided into capacitive, resistive, infrared, sonic and image processing based on the working principle of the sensor. The infrared touch screen uses a diode that transmits and receives infrared rays to form a raster that can be blocked, and the signal is blocked as an operating point.
請參考第1圖，第1圖是習知之紅外線觸控屏的結構示意圖；第1圖中，習知之紅外線觸控屏100不外乎由在縱軸方向成對之紅外線發射模組110與紅外線接收模組140，與在橫軸方向成對之紅外線發射模組130與紅外線接收模組120所組成。其工作原理即在於當觸控點102出現時，會遮斷紅外線，形成縱軸遮斷信號與橫軸遮斷信號。顯而易見地，紅外線發射模組110與紅外線發射模組130發射的紅外線信號，必須能被紅外線接收模組140與紅外線接收模組120接收，且清楚地跟自然界中的紅外線信號源區隔出來。所以，任一組紅外線發射模組與紅外線接收模組間的距離越遠，所需要的發射功率便要越大，且功率亦不可能被無限制地 增強。 Please refer to FIG. 1 . FIG. 1 is a schematic structural view of a conventional infrared touch screen. In FIG. 1 , the conventional infrared touch screen 100 is different from the infrared emitting module 110 and infrared rays paired in the longitudinal direction. The receiving module 140 is composed of an infrared emitting module 130 and an infrared receiving module 120 that are paired in the horizontal axis direction. The working principle is that when the touch point 102 appears, the infrared rays are blocked, and the vertical axis interception signal and the horizontal axis interception signal are formed. Obviously, the infrared signal emitted by the infrared emitting module 110 and the infrared emitting module 130 must be received by the infrared receiving module 140 and the infrared receiving module 120, and clearly separated from the infrared signal source in nature. Therefore, the farther the distance between any group of infrared transmitting modules and the infrared receiving module is, the greater the required transmitting power is, and the power cannot be unrestricted. Enhanced.
因此，本新型之一技術態樣是在提供一種可延伸的紅外線觸控屏，以實現在一個軸向維度上無限延伸的需求。 Therefore, one aspect of the present invention is to provide an extendable infrared touch screen to achieve the requirement of infinite extension in one axial dimension.
依據本技術態樣一實施方式，提出一種可延伸的紅外線觸控屏，用以提供一多媒體內容播放區，包括一頂部電路裝置與一底部電路裝置。頂部電路裝置具有至少兩紅外線發射器，相鄰間距為X1，頂部電路裝置與多媒體內容播放區上緣之距離為Y1，每一紅外線發射器之半射角為Z1，且滿足tan Z1=1/2(X1/Y1)。底部電路裝置具有多個紅外線接收器，用以接收兩紅外線發射器之信號。其中，兩紅外線發射器以斜角掃描方式，於一觸控位置交錯，進而使多個紅外線接收器產生一遮斷信號以定義觸控位置。藉此，多媒體內容播放區可朝非頂部與非底部的兩側方向延伸，而仍具備觸控功能。換句話說，因為觸控點的定位不再需要橫軸方向的紅外線遮斷信號，故而本實施方式之可延伸的紅外線觸控屏亦不需要橫軸的紅外線發射模組與紅外線接收模組。 According to an embodiment of the present invention, an extendable infrared touch screen is provided for providing a multimedia content playing area, including a top circuit device and a bottom circuit device. The top circuit device has at least two infrared emitters, the adjacent spacing is X 1 , the distance between the top circuit device and the upper edge of the multimedia content playing area is Y 1 , the half angle of each infrared emitter is Z 1 , and satisfies tan Z 1 = 1/2 (X 1 /Y 1 ). The bottom circuit device has a plurality of infrared receivers for receiving signals from the two infrared emitters. The two infrared emitters are interlaced at a touch position in an oblique scan mode, thereby causing the plurality of infrared receivers to generate an interrupt signal to define the touch position. Thereby, the multimedia content playing area can extend toward both sides of the non-top and non-bottom, and still has a touch function. In other words, since the positioning of the touch point no longer requires the infrared occlusion signal in the horizontal axis direction, the extendable infrared touch screen of the present embodiment does not require the infrared ray emitting module and the infrared ray receiving module of the horizontal axis.
依據本技術態樣其他實施方式，上述底部電路裝置亦可設計有至少兩紅外線發射器，相鄰間距為X2，底部電路裝置與多媒體內容播放區下緣之距離為Y2，兩紅外線發射器之半射角為Z2，滿足tan Z2=1/2(X2/Y2)；且頂部電路裝置具有多個紅外線接收器，用以接收所述兩紅外線發射器之信號。 According to other embodiments of the present technical aspect, the bottom circuit device may also be designed with at least two infrared emitters, the adjacent spacing is X 2 , and the distance between the bottom circuit device and the lower edge of the multimedia content playing area is Y 2 , and the two infrared emitters The half angle of incidence is Z 2 , satisfying tan Z 2 = 1/2 (X 2 /Y 2 ); and the top circuit device has a plurality of infrared receivers for receiving signals from the two infrared emitters.
另一方面，上述頂部電路裝置之兩紅外線發射器與 底部電路裝置之兩紅外線發射器可於水平座標位置上對應地重疊排列或交錯排列，其選擇可搭配紅外線發射器之光型、演算法設計與觸控點特定位置靈敏度的需求來決定之。此外，所述紅外線發射器可由紅外線發光二極體來實現之；相應地，所述紅外線接收器亦可由紅外線接收二極體來實現之。 On the other hand, the two infrared emitters of the above top circuit device The two infrared emitters of the bottom circuit device can be arranged in a correspondingly overlapping or staggered arrangement at the horizontal coordinate position, and the selection can be determined by the requirements of the light type of the infrared emitter, the algorithm design and the sensitivity of the specific position of the touch point. Furthermore, the infrared emitter can be realized by an infrared light emitting diode; accordingly, the infrared receiver can also be realized by an infrared receiving diode.
最後，底部電路裝置可由多個拼接電路板信號串聯而成；頂部電路裝置亦可由多個拼接電路板信號串聯而成。更進一步的來說，每一個拼接電路板皆可以具有至少兩個上述的紅外線發射器以實現上述的無限延伸機制；藉此，多個獨立運作功能完整之拼接電路板所組成的底部電路裝置或頂部電路裝置，便可進一步實現多點觸控的功能。 Finally, the bottom circuit device can be formed by connecting a plurality of spliced circuit board signals in series; the top circuit device can also be formed by connecting a plurality of spliced circuit board signals in series. Further, each splicing circuit board may have at least two infrared ray emitters as described above to implement the above-described infinite extension mechanism; thereby, a plurality of splicing circuit boards composed of independent independent functional splicing circuit boards or The top circuit device can further realize the multi-touch function.
綜上所述，前述諸實施方式之可延伸的紅外線觸控屏，能應用在大型的、長橫軸的廣告看板；克服習知之紅外線發射模組與紅外線接收模組間距離太遠，而無法有效作動的缺憾。 In summary, the extendable infrared touch screen of the foregoing embodiments can be applied to a large, long horizontal axis advertising billboard; the distance between the conventional infrared transmitting module and the infrared receiving module is too far to be overcome. The shortcomings of effective action.

A schematic structural view of a touch screen; FIG. 4 is a structure of an extendable infrared touch screen according to still another embodiment of the present invention. FIG. 5 is a schematic diagram of a multi-point operation of FIG. 4; and FIG. 6 is a schematic structural view of an extendable infrared touch screen according to still another embodiment of the present invention.
請參考第2圖，第2圖是本創作一實施方式之可延伸的紅外線觸控屏的結構示意圖。第2圖中，可延伸的紅外線觸控屏200主要係由頂部電路裝置210與底部電路裝置220所構成，多媒體內容播放區201則位於兩者之間。在應用上，多媒體內容播放區201通常是大型的、長橫軸的廣告看板，使用者站在看板前，通常身高約當於多媒體內容播放區201的縱軸高度。 Please refer to FIG. 2 , which is a schematic structural diagram of an extendable infrared touch screen according to an embodiment of the present invention. In FIG. 2, the extendable infrared touch screen 200 is mainly composed of a top circuit device 210 and a bottom circuit device 220, and the multimedia content playing area 201 is located between the two. In application, the multimedia content playing area 201 is usually a large, long horizontal axis advertising billboard, and the user stands in front of the kanban, usually about the height of the vertical axis of the multimedia content playing area 201.
頂部電路裝置210至少具有紅外線發射器211與紅外線發射器212，兩者相鄰間距為X1，頂部電路裝置210與多媒體內容播放區201上緣之距離為Y1，此即構成非供操作的方形無效區域(X1Y1)。紅外線發射器211、212可選用掃描式雷射光源(MEMS)，但成本較高；其亦可基於成本考量，選用紅外線發光二極體；此時在設計上，紅外線發射器211、212的半射角Z1，即掃描範圍的一半或有效發光範圍的一半，且滿足tan Z1=1/2(X1/Y1)。 The top circuit device 210 has at least an infrared emitter 211 and an infrared emitter 212, the adjacent spacing of which is X 1 , and the distance between the top circuit device 210 and the upper edge of the multimedia content playing area 201 is Y 1 , which constitutes a non-operational operation. Square invalid area (X 1 Y 1 ). The infrared emitters 211 and 212 may be selected from a scanning laser light source (MEMS), but the cost is high; and the infrared light emitting diode may be selected based on cost considerations; at this time, half of the infrared emitters 211 and 212 are designed. The angle of incidence Z 1 , which is half of the scanning range or half of the effective illumination range, satisfies tan Z 1 = 1/2 (X 1 /Y 1 ).
另一方面，底部電路裝置220則具有多個紅外線接收器223，以接收上述兩紅外線發射器211、212之信號。藉此，當兩紅外線發射器211、212以斜角掃描方式，在觸控點202被遮斷，多個紅外線接收器223接收到兩個遮斷信號，就可以逆推出遮斷信號 交錯的位置，進而定義出觸控點202的觸控位置。整體觀之，本實施方式之可延伸的紅外線觸控屏200即可供多媒體內容播放區201朝非頂部與非底部的兩側方向延伸，而仍具備觸控功能。 On the other hand, the bottom circuit device 220 has a plurality of infrared receivers 223 for receiving signals from the two infrared emitters 211, 212. Thereby, when the two infrared ray emitters 211, 212 are obliquely scanned, the touch point 202 is blocked, and the plurality of infrared ray receivers 223 receive two occlusion signals, and the occlusion signal can be reversely pushed out. The staggered positions further define the touch position of the touch point 202. As a whole, the extendable infrared touch screen 200 of the present embodiment can extend the multimedia content playing area 201 toward the non-top and non-bottom sides, and still has a touch function.
請復參考第3圖，第3圖是本創作另一實施方式之可延伸的紅外線觸控屏的結構示意圖；第3圖中，可延伸的紅外線觸控屏300承襲前述實施方式之設計理念，且進一步改良之，以於多媒體內容播放區301實現多點觸控的功能。此處之頂部電路裝置310實係前述之頂部電路裝置210與底部電路裝置220之電路功能的整合；相應地，此處之底部電路裝置320亦同。 Please refer to FIG. 3, which is a schematic structural view of an extendable infrared touch screen according to another embodiment of the present invention; and in FIG. 3, the extendable infrared touch screen 300 inherits the design concept of the foregoing embodiment. Further improved, the multimedia content playing area 301 implements a multi-touch function. The top circuit device 310 herein is integrated with the circuit functions of the aforementioned top circuit device 210 and bottom circuit device 220; accordingly, the bottom circuit device 320 herein is also the same.
以邏輯運算原理觀之，兩條遮斷信號線可決定一觸控點，故而四條遮斷信號線即可在多媒體內容播放區301上定義出兩個觸控點302、303；依序類推，在多媒體內容播放區301的單位面積內(如所繪示之虛框)，放置越多紅外線發射器311、312、321、322與相應的紅外線接收器313、323，則單位面積內可實現之觸控點數量就會更多。 According to the logic operation principle, the two occlusion signal lines can determine a touch point, so the four occlusion signal lines can define two touch points 302, 303 on the multimedia content play area 301; Within the unit area of the multimedia content playing area 301 (as shown by the dashed box), the more infrared emitters 311, 312, 321, 322 and the corresponding infrared receivers 313, 323 are placed, the unit area can be realized. The number of touch points will be more.
基於此一設計理念所實現之可延伸的紅外線觸控屏300，會在多媒體內容播放區301的上方形成前述的方形無效區域(X1Y1)；同理，底部電路裝置320上的紅外線發射器321、322亦依其參數設定：兩紅外線發射器321、322相鄰間距為X2，底部電路裝置320與多媒體內容播放區301下緣之距離為Y2，紅外線發射器321、322之半射角為Z2，且滿足tan Z2=1/2(X2/Y2)；進而在多媒體內容播放區301的下方形成非供操作的方形無效區域(X2Y2)。易言 之，對使用者而言，超出頭頂與低於膝蓋的區域，都是合理預設為不予提供觸控功能的。 The extendable infrared touch screen 300 realized based on this design concept forms the square ineffective area (X 1 Y 1 ) above the multimedia content playing area 301; similarly, the infrared emitting on the bottom circuit device 320 The devices 321 and 322 are also set according to their parameters: the distance between the two infrared emitters 321, 322 is X 2 , the distance between the bottom circuit device 320 and the lower edge of the multimedia content playing area 301 is Y 2 , and the half of the infrared emitters 321 and 322 The angle of incidence is Z 2 and satisfies tan Z 2 = 1/2 (X 2 /Y 2 ); further, a non-operating square ineffective area (X 2 Y 2 ) is formed below the multimedia content playing area 301. In other words, for the user, the area beyond the head and below the knee is reasonably preset to not provide touch function.
請再參考第4圖，第4圖是本創作又一實施方式之可延伸的紅外線觸控屏的結構示意圖。第4圖中，可延伸的紅外線觸控屏400為提供多媒體內容播放區401多點觸控功能，而在單位面積內設有紅外線發射器411、412、421、422；值得注意的是，此處要探討兩個議題，其一為上方紅外線發射器411、412與下方紅外線發射器421、422安置的相對位置與取捨，其二則為消除鬼點的機制。 Please refer to FIG. 4 again. FIG. 4 is a schematic structural diagram of an extendable infrared touch screen according to still another embodiment of the present invention. In FIG. 4, the extendable infrared touch screen 400 provides a multi-touch function for the multimedia content playing area 401, and infrared emitters 411, 412, 421, and 422 are provided in a unit area; Two topics are to be discussed, one is the relative position and trade-off between the upper infrared emitters 411, 412 and the lower infrared emitters 421, 422, and the other is the mechanism for eliminating ghost points.
承前所述，可延伸的紅外線觸控屏400是由兩條斜角掃描的遮斷信號線，交錯構成一個觸控位置；所以隨著紅外線發射器411、412、421、422的光型與多媒體內容播放區401的實際需求，可搭配將頂部電路裝置之兩紅外線發射器411、412與底部電路裝置之兩紅外線發射器421、422，在水平座標位置上，對應地排列成重疊或交錯模式。第4圖中所示即為交錯模式之一適例，在交錯模式中，紅外線發射器411、412、421、422的光型可以較為集中，有利於在單位面積內提供較多的觸控點，但不利於消除鬼點的機制，如第2圖所示之重疊模式則反之。 As described above, the extendable infrared touch screen 400 is an interrupted signal line scanned by two oblique angles, which are staggered to form a touch position; therefore, with the light type and multimedia of the infrared emitters 411, 412, 421, and 422 The actual requirements of the content play area 401 can be matched with the two infrared emitters 411, 412 of the top circuit device and the two infrared emitters 421, 422 of the bottom circuit device, correspondingly arranged in an overlapping or interlaced mode at the horizontal coordinate position. As shown in FIG. 4, it is an appropriate example of the interlaced mode. In the interlaced mode, the light patterns of the infrared emitters 411, 412, 421, and 422 can be concentrated, which is advantageous for providing more touch points in a unit area. , but not conducive to the elimination of ghost points, such as the overlap mode shown in Figure 2 is the opposite.
接下來，請參考第5圖，第5圖是第4圖之多點操作示意圖，並用以說明消除鬼點的機制。如前所述，紅外線發射器411、412所形成的遮斷信號，除了交錯在觸控點402、403外，還會交錯在鬼點(如圖所示圓形虛框)；因此，若同向或對向的紅外線發射 器，此處以對向的紅外線發射器421為例，能提供一個確認信號，確認圓形虛框實非遮斷，則可消除此一鬼點。但是，在交錯模式中，斜角掃描就少掉了至少一組角度的確認信號，即紅外線發射器411到紅外線發射器421的角度；反之，因本創作係利用斜角掃描，實現橫向維度的無限延伸，在重疊模式中，紅外線發射器311到紅外線發射器321的角度原即不予採用，故並無損失。 Next, please refer to Figure 5, which is a schematic diagram of the multi-point operation of Figure 4, and illustrates the mechanism for eliminating ghost points. As described above, the occlusion signals formed by the infrared emitters 411 and 412 are interlaced at the touch points 402 and 403, and are also staggered at the ghost points (as shown in the circular virtual frame); Infrared emission to or opposite For example, the opposite infrared emitter 421 can provide a confirmation signal to confirm that the circular virtual frame is not blocked, and the ghost point can be eliminated. However, in the interlaced mode, the oblique angle scan eliminates at least one set of angle confirmation signals, that is, the angles of the infrared emitter 411 to the infrared emitter 421; conversely, because the author uses the oblique angle scan to achieve the lateral dimension Infinitely extending, in the overlap mode, the angle from the infrared emitter 311 to the infrared emitter 321 is not used at all, so there is no loss.
最後，請參考第6圖，第6圖是本創作再一實施方式之可延伸的紅外線觸控屏的結構示意圖。第6圖中，可延伸的紅外線觸控屏500係利用拼接電路板530來串聯拼裝，組成頂部電路裝置510與底部電路裝置520；在設計上，一個拼接電路板530即可搭配設有兩個紅外線發射器與多個紅外線接收器，且首尾兩端分別以公接頭532與母接頭531形成信號串聯。 Finally, please refer to FIG. 6. FIG. 6 is a schematic structural diagram of an extendable infrared touch screen according to still another embodiment of the present invention. In Fig. 6, the extendable infrared touch screen 500 is assembled in series by using a splicing circuit board 530 to form a top circuit device 510 and a bottom circuit device 520. In design, one splicing circuit board 530 can be matched with two The infrared emitter and the plurality of infrared receivers are connected in series with the female connector 531 by the male connector 532 and the female connector 531.
雖然本新型已以實施方式揭露如上，然其並非用以限定本新型，任何熟習此技藝者，在不脫離本新型之精神和範圍內，當可作各種之更動與潤飾，因此本新型之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Any one skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention.
