請參考第一圖,本發明之觸控螢幕之點擊操作結構,包含: 一觸控面板10,該觸控面板10可以接收來自上方的觸壓或感應面板上方的電性反應,該觸控面板上形成一觸控軌跡,其定義為初始點落在該觸控面板之影像上的觸壓或電性反應形成軌跡信號。該觸控面板10可以是電阻式、電容式等各種觸控面板10,也可以是透明或不透明之觸控面板10。較佳者為透明之觸控面板10。 Please refer to the first figure, the click operation structure of the touch screen of the present invention, comprising: a touch panel 10, the touch panel 10 can receive an electrical response from above the touch or sensing panel, and the touch panel forms a touch track, which is defined as an initial point falling on the touch panel. The touch or electrical response on the image forms a trajectory signal. The touch panel 10 can be a resistive or capacitive touch panel 10 or a transparent or opaque touch panel 10 . A transparent touch panel 10 is preferred.
一觸控電路20,連接該觸控面板10,用以接收來自該觸控面板10的觸控軌跡。 A touch circuit 20 is connected to the touch panel 10 for receiving a touch track from the touch panel 10 .
該觸控電路20包含:一邏輯響應電路22,依據該觸控軌跡,該邏輯響應電路22可產生對應的操作,而令在一顯示幕40上的影像可以依據該操作進行不同的動作。 The touch circuit 20 includes a logic response circuit 22, according to which the logic response circuit 22 can generate a corresponding operation, so that the image on a display screen 40 can perform different actions according to the operation.
如第二圖之結構所示,在本發明中,該觸控面板10的設置位置為直接設置於顯示幕40上方(如智慧型手機或平板電腦)及不與顯示幕40直接接合(如筆記型電腦的手寫板與顯示幕40分開)之一種方式。 As shown in the structure of the second figure, in the present invention, the touch panel 10 is disposed directly above the display screen 40 (such as a smart phone or a tablet) and does not directly engage with the display screen 40 (such as a note). A way of separating the tablet of the computer from the display screen 40).
一影像處理單元30,接收該觸控電路20之邏輯響應電路22的操作,而令顯示幕40上的一影像產生對應的動作。 An image processing unit 30 receives the operation of the logic response circuit 22 of the touch circuit 20 to cause an image on the display screen 40 to generate a corresponding action.
其中該邏輯響應電路22將該顯示幕40上的影像劃分為兩區域,如第三圖所示,一為影像移動區41,一為影像縮放區42。當該觸控軌跡落在該影像移動區41時,該邏輯響應電路22產生影像移動的指令,而令該影像依據軌跡向量的方向移動,此指令再傳至影像處理單元30。而令螢幕上影像產 生對應的移動。當該觸控軌跡落在影像縮放區42,將使得影像產生放大縮小的效應,當觸控軌跡的方向由內向外(即向螢幕外框的方向),將產生影像放大的指令,而經影像處理單元30令顯示幕40上的影像產生對應的放大效果,反之亦然。 The logic response circuit 22 divides the image on the display screen 40 into two regions. As shown in the third figure, one is the image moving area 41 and the other is the image zooming area 42. When the touch track falls in the image moving area 41, the logic response circuit 22 generates an image movement instruction, and the image is moved according to the direction of the track vector, and the instruction is transmitted to the image processing unit 30. And make the video on the screen The corresponding movement is born. When the touch track falls in the image zooming area 42, the image will be enlarged and reduced. When the direction of the touch track is from the inside to the outside (ie, in the direction of the screen frame), an image enlargement command will be generated, and the image is generated. The processing unit 30 causes the image on the display screen 40 to produce a corresponding magnification effect, and vice versa.
本發明之影像縮放區操作方式如下:如該觸控軌跡為一點向內的軌跡(從影像縮放區開始42,可延續至移動區41)則表示將影像縮小,所以該邏輯響應電路22及影像處理單元30將會產生對應的動作,反之亦然。 The image zooming area of the present invention operates as follows: if the touch track is a point inward track (starting from the image zooming area 42 and continuing to the moving area 41), the image is reduced, so the logic response circuit 22 and the image Processing unit 30 will generate a corresponding action, and vice versa.
本發明之影像移動區操作方式如下如該觸控軌跡為一點(從影像移動區41開始,可延續至影像縮放區42)的觸控軌跡則表示將該影像依據軌跡向量的方向移動。 The image moving area of the present invention operates in the following manner. If the touch track is a point (from the image moving area 41, the image zooming area 42 can be continued), the touch track indicates that the image is moved according to the direction of the track vector.
請參考第四圖,在實際應用上,該影像移動區41係指在影像中央的一限定範圍,而該範圍外的影像其餘部分則為該影像縮放區42。 Please refer to the fourth figure. In practical applications, the image moving area 41 refers to a limited range in the center of the image, and the rest of the image outside the range is the image zooming area 42.
本發明根據不同的觸控軌跡具有以下多種的實施例:單軌跡操作即該觸控軌跡為單點向特定方向移動的軌跡,使得該觸控電路20接收到該軌跡訊號時,使得該邏輯響應電路22產生對應的動作指令,以下以實施例作為說明:其中在影像被放大時,該觸控電路20接收到單點的觸控軌跡(意指將手指在螢幕上點擊一下)且當下該觸控螢幕顯示的影像為純影像(即不包含欄位及連結),該邏輯響應電路22則會根據該觸控軌跡產生還原影像初始顯示大小的指 令,並將該指令傳送至該影像處理單元30,使得該顯示幕40中的影像還原初始顯示大小;請參考第五圖,其中該觸控電路20接收到圓形或圓弧型的觸控軌跡時,該邏輯響應電路22則會根據該觸控軌跡產生旋轉影像的指令,並將該指令傳送至該影像處理單元30,使得該顯示幕40中的影像產生繞特定中心旋轉的動作。 The present invention has the following various embodiments according to different touch trajectories: a single track operation, that is, the touch track is a track in which a single point moves in a specific direction, so that the touch circuit 20 makes the logic response when receiving the track signal. The circuit 22 generates a corresponding action command, which is described below by way of an embodiment: wherein when the image is enlarged, the touch circuit 20 receives a single touch track (meaning that the finger is clicked on the screen) and the current touch The image displayed on the control screen is a pure image (ie, no field and link is included), and the logic response circuit 22 generates a finger for restoring the initial display size of the image according to the touch track. And the command is transmitted to the image processing unit 30, so that the image in the display screen 40 restores the initial display size; please refer to the fifth figure, wherein the touch circuit 20 receives a circular or circular touch. During the trajectory, the logic response circuit 22 generates an instruction to rotate the image according to the touch trajectory, and transmits the instruction to the image processing unit 30, so that the image in the display screen 40 generates an action of rotating around a specific center.
雙軌跡操作,即該觸控軌跡為兩點的觸控軌跡,使得該觸控電路20接收到該軌跡訊號時,使得該邏輯響應電路22產生對應的動作指令,以下以實施例作為說明:請參考第六圖,其中該觸控電路20接收到兩點的觸控軌跡時(即用雙指在觸控螢幕的影像上點一次),該邏輯響應電路22則會根據該觸控軌跡產生影像放大的指令,並將該指令傳送至該影像處理單元30,以將影像放大直到該兩點碰到顯示幕的邊緣為止;在一操作例中,當觸控電路20接收到一點及一線所構成的雙觸控軌跡,且兩者約同時出現時(即用雙指接觸控螢幕,然後一指放開;剩餘該點不限定要在縮放區),則邏輯響應電路22及影像處理單元30會根據該一指觸控軌跡向內而產生影像縮小的指令;反之,如該觸控軌跡向外,則會產生放大影像的動作(此時為進入縮放模式)。如果所感測的觸控軌跡為一圓弧形軌跡時,該邏輯響應電路則會根據該觸控軌跡產生影像旋轉的指令,並將該指令傳送至該影像處理單元,使得該顯示幕中的影像產生旋轉的動作。 The dual-track operation, that is, the touch track is a two-point touch track, so that when the touch circuit 20 receives the track signal, the logic response circuit 22 generates a corresponding action command. The following is an example: Referring to the sixth figure, when the touch circuit 20 receives the touch track of two points (ie, clicks on the image of the touch screen with two fingers), the logic response circuit 22 generates an image according to the touch track. Enlarging the command, and transmitting the command to the image processing unit 30 to enlarge the image until the two points touch the edge of the display screen; in an operation example, when the touch circuit 20 receives a point and a line The dual touch track, and when the two appear at the same time (ie, using the two-finger touch control screen, then one finger is released; the remaining point is not limited to be in the zoom area), then the logic response circuit 22 and the image processing unit 30 will According to the one-finger touch track, an image reduction instruction is generated inward; conversely, if the touch track is outward, an action of enlarging the image is generated (in this case, entering the zoom mode). If the sensed touch track is a circular arc track, the logic response circuit generates an image rotation command according to the touch track, and transmits the command to the image processing unit to make the image in the display screen Produces a rotating motion.
在一操作例中,當該觸控電路20接收到特定的兩時段出現兩點觸控軌跡時(即用雙指在觸控螢幕上點兩次),該邏輯響應電路22則會根據該觸控軌跡產生將當下的影像以一影像像素(Pixel)對應一顯示幕40像素(Pixel)的方式呈現的指令,並將該指令傳送至該影像處理單元30,使得該觸控面板10所顯示的影像之影像解析度大小等同於螢幕解析度大小(如顯示幕40為512X1024 Pixels則該影像像素上也以512X1024 Pixels的方式顯示),意指該影像會藉由該觸控軌跡使得影像以全螢幕方式呈現,此時為進入縮放模式。 In an operation example, when the touch circuit 20 receives a two-touch track in a specific two time periods (ie, two points are clicked on the touch screen with two fingers), the logic response circuit 22 according to the touch The control track generates an instruction to present the current image in a manner that a pixel (Pixel) corresponds to a display screen of 40 pixels (Pixel), and transmits the command to the image processing unit 30 so that the touch panel 10 displays The image resolution of the image is equal to the resolution of the screen (for example, if the display screen 40 is 512×1024 Pixels, the image pixel is also displayed by 512×1024 Pixels), meaning that the image will make the image full screen by the touch track. The mode is presented, in this case, the zoom mode is entered.
其中該影像經特定軌跡以全螢幕方式呈現之後,當該觸控電路20再接收到在特定兩時段出現兩點的觸控軌跡(即用雙指在觸控螢幕上點兩次),該邏輯響應電路22則會作出將影像還原成原始影像大小的指令,並將該指令傳送至該影像處理單元30,使得該觸控面板10所顯示的放大影像產生還原初始顯示大小的動作,此時意指離開縮放模式。 After the image is presented in a full screen manner through a specific track, when the touch circuit 20 receives a touch track that appears at two points in a specific two time periods (ie, two points are clicked on the touch screen twice), the logic The response circuit 22 sends an instruction to restore the image to the original image size, and transmits the command to the image processing unit 30, so that the enlarged image displayed by the touch panel 10 generates an action for restoring the initial display size. Refers to leaving the zoom mode.
本發明之目的係在於改進習知技術對於觸控面板使用時,常發生誤觸面板而使得觸控面板造成指令誤判的情況。因此本發明藉由將觸控電路進行分區的方式,使得在圖型操作上不會造成誤觸的情形發生。且根據圖形的使用具有多種相關的觸控軌跡的反應,使得對於在智慧型手機或是筆記型電腦的觸控板對於圖形觀看及操作能夠有更佳的使用性。 The purpose of the present invention is to improve the situation in which the touch panel is misused when the touch panel is used in the prior art, and the touch panel causes a misjudgment of the command. Therefore, in the present invention, the touch circuit is partitioned in such a manner that no accidental touch occurs in the operation of the pattern. And according to the use of the graphics, there are a variety of related touch track responses, which makes the touchpad on the smart phone or the notebook computer more usable for graphic viewing and operation.
綜上所述,本案人性化之體貼設計,相當符合實際需求。其具體改進現有缺失,相較於習知技術明顯具有突破性之進 步優點,確實具有功效之增進,且非易於達成。本案未曾公開或揭露於國內與國外之文獻與市場上,已符合專利法規定。 In summary, the humanized design of this case is quite in line with actual needs.
