根據本發明之一實施例，其中，所述的該些座標係用以定義出外接電子裝置之子顯示區的範圍。舉例來說，當該子顯示區係為一長方形時，該些座標係分別位於該子顯示區之左上角、右上角、左下角、以及右下角。According to an embodiment of the present invention, the said coordinates are used to define the range of the sub-display area of the external electronic device. For example, when the sub-display area is a rectangle, the coordinates are located at the upper left corner, upper right corner, lower left corner, and lower right corner of the sub display area.

在一實施例中，其中，所述的第一顯示區域與第二顯示區域係分別為主顯示區中彼此互補的兩對應區域。其中，第二顯示區域係與該外接電子裝置之所述的子顯示區所定義之區域範圍一致。換言之，第二顯示區域係為外接電子裝置之報點區域。同時，第一顯示區域係為外接電子裝置之不報點區域，當第一顯示區域係為主電子裝置之報點區域時，第二顯示區域係為主電子裝置之不報點區域。In an embodiment, the first display area and the second display area are two corresponding areas that are complementary to each other in the main display area. Wherein, the second display area is consistent with the area defined by the sub-display area of the external electronic device. In other words, the second display area is the reporting area of the external electronic device. Meanwhile, the first display area is the non-reporting area of the external electronic device. When the first display area is the reporting area of the main electronic device, the second display area is the non-reporting area of the main electronic device.

根據本發明之一較佳實施例，所述的主電子裝置中係至少包含有一微處理器與一觸控晶片，使得外接電子裝置係通過一通訊介面連接該微處理器而插接於主電子裝置中，在此情況下，本發明係揭示有一主控制線路與一新增之子控制線路，其中，所述的主控制線路與新增之子控制線路係各自地連接於該微處理器與觸控晶片之間，使得傳送至主電子裝置之一該封包訊號係透過該主控制線路傳送，而傳送至外接電子裝置之另一該封包訊號則係透過該子控制線路傳送。According to a preferred embodiment of the present invention, the main electronic device includes at least a microprocessor and a touch chip, so that the external electronic device is connected to the microprocessor through a communication interface and plugged into the main electronic device.

其中，第3圖係為根據本發明一實施例主電子裝置之結構示意圖，如本案圖示第3圖所示，一主電子裝置100係至少包括一微處理器（microprocessor，MCU）102、一觸控晶片（Touch sensor IC）104、一液晶控制器（Scaler）106、以及一時序控制器（T-con）108。一外接電子裝置200係通過一通訊介面31連接該微處理器102而插接於主電子裝置100中，其中，該通訊介面31例如可為通用序列匯流排（Universal Serial Bus，USB）、高畫質多媒體介面（High Definition Multimedia Interface，HDMI）、顯示接口（Display Port ，DP）、或視頻圖形陣列（Video Graphics Array，VGA）等傳輸介面。熟習本領域並具備通常知識之技術人士當可依據實際裝置之需求而選用適切之通訊界面，唯本發明並不以此為限。在其中一實施例中，所述的主電子裝置100與其插接之一外接電子裝置200例如可以為一組允許外接顯示的主電腦以及外接電腦。Wherein, Fig. 3 is a schematic diagram of the structure of a main electronic device according to an embodiment of the present invention. As shown in Fig. 3 of the diagram in this case, a main electronic device 100 includes at least one microprocessor (MCU) 102, one Touch sensor IC 104, a liquid crystal controller (Scaler) 106, and a timing controller (T-con) 108. An external electronic device 200 is connected to the microprocessor 102 through a communication interface 31 and plugged into the main electronic device 100. The communication interface 31 may be, for example, a universal serial bus (USB) or high-resolution High Definition Multimedia Interface (HDMI), Display Port (DP), or Video Graphics Array (VGA) and other transmission interfaces. Those who are familiar with the field and have general knowledge can choose an appropriate communication interface according to the needs of the actual device, but the present invention is not limited to this. In one of the embodiments, the main electronic device 100 and an external electronic device 200 plugged into it can be, for example, a group of main computers and external computers that allow external display.

請配合參閱第4圖所示，其係為根據本發明一實施例之外接顯示共用觸控的操作方法之步驟流程圖。請參見其中如步驟S40所示，首先，由主電子裝置100偵測是否有與其連接之外接電子裝置200插接於其上。當有外接電子裝置200成功插接於主電子裝置100時，主電子裝置100之主顯示區110中的觸控面板（touch panel）112上係可呈現出子母畫面，意即包含顯示出該外接電子裝置200之一子顯示區202。其中，該子顯示區202的範圍大小係可由複數個座標所定義，如第5圖所示，其係為根據本發明其中一種實施態樣之主電子裝置，當此主電子裝置用以顯示出子母畫面之示意圖；承以此例而言，如圖所示，當此子顯示區202例如為一長方形時，我們首先先定義出原點(0,0)的位置，之後，則該些座標，包含：(a1,b1)、(a2,b2)、(a3,b3)、(a4,b4)係分別位於該子顯示區202之左上角、右上角、左下角、以及右下角，本發明係可通過這些座標來定義出外接電子裝置200之子顯示區202的範圍。Please refer to FIG. 4, which is a flow chart of the operation method of external display shared touch according to an embodiment of the present invention. Please refer to it as shown in step S40. First, the main electronic device 100 detects whether there is an external electronic device 200 plugged into it. When the external electronic device 200 is successfully plugged into the main electronic device 100, the touch panel (touch panel) 112 in the main display area 110 of the main electronic device 100 can display a picture-in-picture, which means that the display A sub-display area 202 of the external electronic device 200. Wherein, the size of the sub-display area 202 can be defined by a plurality of coordinates. As shown in FIG. 5, it is a main electronic device according to one of the embodiments of the present invention. When the main electronic device is used to display Schematic diagram of the picture-in-picture; for this example, as shown in the figure, when the sub-display area 202 is for example a rectangle, we first define the position of the origin (0,0), and then, Coordinates, including: (a1, b1), (a2, b2), (a3, b3), (a4, b4) are located in the upper left corner, upper right corner, lower left corner, and lower right corner of the sub-display area 202, respectively. The invention can define the range of the sub-display area 202 of the external electronic device 200 through these coordinates.

因此，如步驟S42所示，當外接電子裝置202成功插接於主電子裝置100之後，主電子裝置100之微處理器102係計算外接電子裝置200之該子顯示區202的這些座標。接著，如步驟S44所示，將該些座標，包含：(a1,b1)、(a2,b2)、(a3,b3)、(a4,b4)傳送至主電子裝置100，以根據該些座標(a1,b1)、(a2,b2)、(a3,b3)、(a4,b4)計算出主電子裝置100之主顯示區110中的一第一顯示區域與一第二顯示區域。Therefore, as shown in step S42, after the external electronic device 202 is successfully plugged into the main electronic device 100, the microprocessor 102 of the main electronic device 100 calculates the coordinates of the sub-display area 202 of the external electronic device 200. Then, as shown in step S44, the coordinates, including: (a1, b1), (a2, b2), (a3, b3), (a4, b4), are transmitted to the main electronic device 100, so as to be based on the coordinates (a1, b1), (a2, b2), (a3, b3), (a4, b4) calculate a first display area and a second display area in the main display area 110 of the main electronic device 100.

接著，續請參閱第6圖所示，其係為根據本發明一較佳實施例之主顯示區中第一顯示區域與第二顯示區域之示意圖，如第6圖所示，第一顯示區域61與第二顯示區域62係為該主顯示區110中彼此互補的兩對應區域。其中，請配合參閱第5圖所示，該第二顯示區域62係與外接電子裝置200之子顯示區202所定義之區域範圍一致。也就是說，當在步驟S44中，主電子裝置100接收座標(a1,b1)、(a2,b2)、(a3,b3)、(a4,b4)以計算出所對應的第二顯示區域62與第一顯示區域61之後，該第二顯示區域62與第一顯示區域61係分別呈現為外接電子裝置200與主電子裝置100，二者各自的反應顯示區域。Next, please refer to FIG. 6, which is a schematic diagram of the first display area and the second display area in the main display area according to a preferred embodiment of the present invention. As shown in FIG. 6, the first display area 61 and the second display area 62 are two corresponding areas in the main display area 110 that are complementary to each other. Wherein, please refer to FIG. 5 for reference, the second display area 62 is consistent with the area defined by the sub-display area 202 of the external electronic device 200. That is, when in step S44, the main electronic device 100 receives the coordinates (a1, b1), (a2, b2), (a3, b3), (a4, b4) to calculate the corresponding second display area 62 and After the first display area 61, the second display area 62 and the first display area 61 are respectively presented as the external electronic device 200 and the main electronic device 100, which are their respective reaction display areas.

舉例來說，由於第二顯示區域62係與外接電子裝置200之子顯示區202所定義之區域範圍一致，該第二顯示區域62係對應為該外接電子裝置200之一報點區域。在此情況之下，第一顯示區域61即為該外接電子裝置200之一不報點區域。同時，第一顯示區域61係為主電子裝置100之報點區域，而第二顯示區域62係為主電子裝置100之不報點區域。如此一來，藉由該第一顯示區域61以及第二顯示區域62的劃分，本發明成功實現了同時執行外接顯示與子母畫面功能之發明意旨。For example, since the second display area 62 is consistent with the area defined by the sub-display area 202 of the external electronic device 200, the second display area 62 corresponds to a reporting area of the external electronic device 200. In this case, the first display area 61 is a non-reporting area of the external electronic device 200. Meanwhile, the first display area 61 is the reporting area of the main electronic device 100, and the second display area 62 is the non-reporting area of the main electronic device 100. In this way, through the division of the first display area 61 and the second display area 62, the present invention successfully realizes the intent of simultaneously performing the functions of external display and picture-in-picture.

之後，再如本發明圖示第4圖中的步驟S46所示，本發明即可根據此第一顯示區域61與第二顯示區域62的範圍，傳送對應之二封包訊號分別至主電子裝置100與外接電子裝置200，使其執行各自對應之觸控功能。在此，請同時參閱第3圖所示，我們可以發現的是，相較於先前技術，本發明除了在主電子裝置100之微處理器102與觸控晶片104之間連接有一主控制線路481之外，更在微處理器102與觸控晶片104之間增加一子控制線路482，通過此新穎的電路設計，傳送至主電子裝置100之一封包訊號即可透過主控制線路481傳送，而傳送至外接電子裝置200之另一封包訊號即可透過子控制線路482傳送。其中，根據本發明之一種實施態樣，本發明所設計的主控制線路481與子控制線路482例如係可經由通用序列匯流排（Universal Serial Bus，USB）、內部整合電路（Inter-Integrated Circuit，I2C）、或主從式同步串列通訊（Serial Peripheral Interface Bus，SPI）等通訊介面進行訊號的傳輸。After that, as shown in step S46 in Figure 4 of the present invention, the present invention can send corresponding two packet signals to the main electronic device 100 according to the ranges of the first display area 61 and the second display area 62. With the external electronic device 200, it can execute the corresponding touch function. Here, please refer to Fig. 3 at the same time. What we can find is that compared with the prior art, the present invention has a main control circuit 481 connected between the microprocessor 102 of the main electronic device 100 and the touch chip 104. In addition, a sub-control circuit 482 is added between the microprocessor 102 and the touch chip 104. Through this novel circuit design, a packet signal transmitted to the main electronic device 100 can be transmitted through the main control circuit 481. Another packet signal transmitted to the external electronic device 200 can be transmitted through the sub-control line 482.
