隨著科技的進步，人們除了從傳統的報章雜誌與電視接收資訊之外，隨身攜帶的手機以及隨處可見的液晶顯示器(LCD)，也提供著豐富的資訊。 With the advancement of technology, in addition to receiving information from traditional newspapers and magazines and television, people carry mobile phones and ubiquitous liquid crystal displays (LCDs), which also provide a wealth of information.

由於手機等可隨身攜帶的顯示裝置通常並不大，所以可以顯示資訊的範圍也不會太大。然而，在某些情況下，可能需要較大的顯示範圍，例如，希望與多人分享手機上所顯示的資訊時，手機上所顯示的資訊往往同時只能提供兩三人觀看，若希望分享的人數太多，則只能輪流觀看，無法同時觀看。 Since a display device that can be carried around with a mobile phone or the like is usually not large, the range in which information can be displayed is not too large. However, in some cases, a larger display range may be required. For example, when you want to share the information displayed on the mobile phone with multiple people, the information displayed on the mobile phone can only be viewed by two or three people at the same time. If there are too many people, they can only watch them in turn and cannot watch them at the same time.

In some embodiments, the display screen processing module 160 generates a data packet including a sub display screen corresponding to the slave display device and an identification code corresponding to the slave display device, and transmits the generated data packet to the slave display device.

在另一部份的實施例中，顯示畫面處理模組160所產生的資料封包除了包含與從屬顯示裝置對應之子顯示畫面以及與從屬顯示裝置對應之識別碼之外，更可以包含顯示範圍資料。 In another embodiment, the data packet generated by the display screen processing module 160 may include display range data in addition to the sub display screen corresponding to the slave display device and the identification code corresponding to the slave display device.

另外，顯示畫面處理模組160也可以在判斷各個顯示裝置100的解析度或像素密度不完全相同時，或在無法判斷該顯示畫面的畫面解析度時，根據顯示畫面的影像尺寸、顯示畫面的清晰度指標、或上述兩者的結合產生使各個顯示裝置100調整螢幕解析度的解析度控制指令，並透過傳輸模組140將所產生的解析度控制指令傳送給各個從屬顯示裝置，藉以讓所有從屬顯示裝置依據解析度控制指令調整螢幕解析度，使得所有的顯示裝置100使用相同的像素密度顯示子顯示畫面，其中，顯示畫面的清晰度指標預先由顯示裝置100儲存，且可以被修改，使得附屬顯示裝置能夠清晰顯示子顯示畫面。 In addition, the display screen processing module 160 may determine the image size of the display screen and the display screen when determining that the resolution or the pixel density of each display device 100 is not completely the same or when the screen resolution of the display screen cannot be determined. The sharpness indicator or a combination of the two generates a resolution control command for each display device 100 to adjust the resolution of the screen, and transmits the generated resolution control command to each of the slave display devices via the transmission module 140, so that all The slave display device adjusts the screen resolution according to the resolution control command so that all the display devices 100 display the sub display screen using the same pixel density, wherein the sharpness indicator of the display screen is previously stored by the display device 100 and can be modified so that The sub display device can clearly display the sub display screen.

顯示模組170負責於在顯示裝置100被選擇為主顯示裝置時，暫存被顯示畫面處理模組160對顯示畫面分割產生之與顯示裝置100對應的子顯示畫面，並在相連接之其他顯示裝置顯示所暫存之子顯示畫面時，同步顯示暫存的子顯示畫面。 The display module 170 is responsible for temporarily storing the sub-display screen corresponding to the display device 100 generated by the display screen processing module 160 on the display screen when the display device 100 is selected as the main display device, and is connected to other displays. When the device displays the temporarily displayed sub display screen, the temporarily displayed sub display screen is displayed in synchronization.

顯示模組170也負責顯示裝置100被選擇為從屬顯示裝置時，顯示傳輸模組140所接收之與顯示裝置100相對應的子顯示畫面。 The display module 170 is also responsible for the sub-display screen corresponding to the display device 100 received by the display transmission module 140 when the display device 100 is selected as the slave display device.

若與顯示裝置100相連接之主顯示裝置以資料封包傳送子顯示畫面，且主顯示裝置將所有的資料封包廣撥給從屬顯示裝置，則顯示模組170可以判斷傳輸模組140所接收之資料封包中的識別碼是否與顯示裝置100對應，當顯示模組170判斷傳輸模組140所接收之資料封包中的識別碼與顯示裝置100對應時，暫存傳輸模組140所接收之資料封包中的子顯示畫面，並在主顯示裝置顯示暫存之子顯示畫面時，同步顯示被暫存的子顯示畫面。 If the main display device connected to the display device 100 transmits the sub-display screen with the data packet, and the main display device distributes all the data packets to the subordinate display device, the display module 170 can determine the data received by the transmission module 140. Whether the identification code in the packet corresponds to the display device 100. When the display module 170 determines that the identification code in the data packet received by the transmission module 140 corresponds to the display device 100, the temporary storage module 140 receives the data packet. When the main display device displays the temporary sub-display screen, the sub-display screen that is temporarily stored is displayed in synchronization.

另外，在顯示裝置100被選擇為從屬顯示裝置時，若傳輸模組140所接收的資料封包中包含顯示範圍資料，則顯示模組100在顯示所暫存的子顯示畫面時，會依據資料封包中的顯示範圍資料顯示子顯示畫面。 In addition, when the display device 100 is selected as the slave display device, if the data packet received by the transmission module 140 includes the display range data, the display module 100 displays the temporarily displayed sub-display screen according to the data packet. The display range data in the display shows the sub display screen.

接著以一個實施例來解說本發明的運作系統與方法，並請參照「第2A圖」本發明所提之分割顯示畫面並傳至不同顯示裝置顯示之方法流程圖。 Next, an operational system and method of the present invention will be described with reference to an embodiment. Referring to FIG. 2A, a flowchart of a method for dividing a display screen and transmitting the display to different display devices according to the present invention will be described.

若使用者希望使用本發明，將一台顯示裝置所產生的顯示畫面由多台顯示裝置組合顯示，來獲得較大的顯示範圍，如此，使用者需要提供多個顯示裝置(步驟202)。 If the user desires to use the present invention, a display screen generated by one display device is displayed in combination by a plurality of display devices to obtain a large display range. Thus, the user needs to provide a plurality of display devices (step 202).

在本實施例中，假設使用者準備了三個支援本發明的顯示裝置，每一個顯示裝置在啟動本發明後，各個顯示裝置的偵測模組110可以開始偵測周圍是否有同樣支援本發明的其他顯示裝置(步驟211)。 In this embodiment, it is assumed that the user has prepared three display devices that support the present invention. After the display device is activated, the detection module 110 of each display device can start detecting whether the surrounding supports the present invention. Other display devices (step 211).

當各個顯示裝置的偵測模組110都偵測到另外兩台顯示裝置後，各個顯示裝置的主從決定模組120可以允許選擇其中一台顯示裝置為主顯示裝置，另外兩台顯示裝置為從屬顯示裝置(步驟215)。在本實施例中，假設使用者開啟了其中一台顯示裝置的熱點功能，則開啟熱點功能的顯示裝置會被自身的主從決定模組120選擇為主顯示裝置，未開啟熱點功能的另外兩台顯示裝置會被選擇從屬顯示裝置。實務上，使用者也可以通過主從決定模組120直接設定其中一台顯示裝置為主顯示裝置，如此，被使用者選擇為主顯示裝置之顯示裝置中的主從決定模組120會選擇自身為主顯示裝置，而未被使用者選擇為主顯示裝置之其他顯示裝置中的主從決定模組120會選擇自身為從屬顯示裝置。 After the detection module 110 of each display device detects two other display devices, the master-slave determination module 120 of each display device may allow one of the display devices to be selected as the main display device, and the other two display devices are The slave display device (step 215). In this embodiment, assuming that the user turns on the hotspot function of one of the display devices, the display device that turns on the hotspot function is selected by the master/slave determination module 120 as the main display device, and the other two of the hotspot functions are not turned on. The display device will be selected as the slave display device. In practice, the user can directly set one of the display devices as the main display device through the master-slave determination module 120. Thus, the master-slave determination module 120 in the display device selected by the user as the main display device selects itself. The master-slave determination module 120 in the other display devices that are not the main display device selected by the user as the main display device selects itself as the slave display device.

在主顯示裝置被選出後，主顯示裝置可以發送連接指令到從屬顯示裝置(步驟222)，從屬顯示裝置在接收到主顯示裝置所發送的連接指令後可以依據連接指令與主顯示裝置建立連接(步驟226)。在本實施例中，主顯示裝置的傳輸模組140會透過無線網路技術傳送連接指令給從屬顯示裝置，從屬顯示裝置的傳輸模組140也會透過無線網路技術與開啟熱點功能之主顯示裝置的傳輸模組140建立無線連接。 After the main display device is selected, the main display device can send a connection command to the slave display device (step 222), and after receiving the connection command sent by the main display device, the slave display device can establish a connection with the main display device according to the connection command ( Step 226). In this embodiment, the transmission module 140 of the main display device transmits a connection command to the slave display device via the wireless network technology, and the transmission module 140 of the slave display device also transmits the main function of the hotspot function through the wireless network technology. The transmission module 140 of the device establishes a wireless connection.

在從屬顯示裝置與主顯示裝置連接後，主顯示裝置的顯示畫面處理模組160可以透過主顯示裝置的傳輸模組140獲取從屬顯示裝置的畫面顯示尺寸(步驟230)。在本實施例中，假設主顯示裝置的顯示畫面處理模組160會透過主顯示裝置的傳輸模組140傳送獲取畫面顯示尺寸的請求至從屬顯示裝置，從屬顯示裝置的傳輸模組140在接收到主顯示裝置所傳送的請求後，會將從屬顯示裝置的畫面顯示尺寸傳回主顯示裝置，如此，主顯示裝置的顯示畫面處理模組160便可以獲取從屬顯示裝置的畫面顯示尺寸。 After the slave display device is connected to the main display device, the display screen processing module 160 of the main display device can acquire the screen display size of the slave display device via the transmission module 140 of the main display device (step 230). In this embodiment, it is assumed that the display screen processing module 160 of the main display device transmits a request for acquiring the screen display size to the slave display device through the transmission module 140 of the main display device, and the transmission module 140 of the slave display device receives the transmission module 140. After the request transmitted by the main display device, the screen display size of the slave display device is transmitted back to the main display device, so that the display screen processing module 160 of the main display device can acquire the screen display size of the slave display device.

在主顯示裝置獲取從屬顯示裝置的畫面顯示尺寸(步驟230)後，主顯示裝置的顯示畫面處理模組160可以判斷主顯示裝置的訊號源101是否產生顯示畫面(步驟240)。在本實施例中，假設訊號源101為主顯示裝置的視頻訊號產生模組。若主顯示裝置中的訊號源101沒有產生顯示畫面，則主顯示裝置的顯示畫面處理模組160會持續的判斷主顯示裝置的訊號源101是否產生顯示畫面。 After the main display device acquires the screen display size of the slave display device (step 230), the display screen processing module 160 of the main display device can determine whether the signal source 101 of the main display device generates a display screen (step 240). In this embodiment, it is assumed that the signal source 101 is a video signal generating module of the main display device. If the signal source 101 in the main display device does not generate a display screen, the display screen processing module 160 of the main display device continuously determines whether the signal source 101 of the main display device generates a display screen.

而當主顯示裝置中的訊號源101產生顯示畫面時，主顯示裝置的顯示畫面處理模組160可以依據所獲取之所有顯示裝置的畫面顯示尺寸，將訊號源101所產生的顯示畫面分割為與各個顯示裝置對應的子顯示畫面(步驟250)。在本實施例中，假設三台顯示裝置的畫面顯示尺寸相同，且三台顯示裝置排列為一直線，例如，主顯示裝置在最左邊，中間與右邊則是從屬顯示裝置，則主顯示裝置的顯示畫面處理模組160會將主顯示裝置中之訊號源101所產生的顯示畫面平均分為左中右三等份，每一等分都是一個子顯示畫面，左邊的子顯示畫面與主顯示裝置對應，右邊與中間的子顯示畫面分別與排列在右方與中間的從屬顯示裝置對應。 When the signal source 101 in the main display device generates a display screen, the display screen processing module 160 of the main display device can divide the display image generated by the signal source 101 into and according to the screen display size of all the displayed display devices. A sub display screen corresponding to each display device (step 250). In this embodiment, it is assumed that the screen display sizes of the three display devices are the same, and the three display devices are arranged in a straight line. For example, the main display device is on the leftmost side, and the middle and right sides are slave display devices, and the display of the main display device is displayed. The screen processing module 160 divides the display screen generated by the signal source 101 in the main display device into three equal parts, the left middle right and the right three equal parts, each of which is a sub display screen, and the left sub display screen and the main display device Correspondingly, the sub-display screens on the right and the middle correspond to the subordinate display devices arranged in the right and the middle, respectively.

在主顯示裝置的顯示畫面處理模組160將顯示畫面分割為與各個顯示裝置對應的子顯示畫面後，主顯示裝置的顯示畫面處理模組160可以透過主顯示裝置的傳輸模組140將分割產生之與從屬顯示裝置對應的子顯示畫面傳送給相對應的從屬顯示裝置(步驟270)。在本實施例中，假設主顯示裝置的顯示畫面處理模組160會先後產生包含與排列於中間之從屬顯示裝置相對應的子顯示畫面以及與排列於中間之從屬顯示裝置相對應的識別碼的資料封包，以及產生包含與排列於右方之從屬顯示裝置相對應的子顯示畫面以及與排列於右方之從屬顯示裝置相對應的識別碼的資料封包，主顯示裝置的傳輸模組140會以無線網路協定的封包格式封裝主顯示裝置之顯示畫面處理模組160所產生的資料封包，並將包含資料封包的網路封包廣播給相連接的從屬顯示裝置，如此，排列於中間與排列右方的兩個從屬顯示裝置都會接收到主顯示裝置的顯示畫面處理模組160所產生的所有資料封包。 After the display screen processing module 160 of the main display device divides the display screen into sub-display screens corresponding to the respective display devices, the display screen processing module 160 of the main display device can generate the segmentation through the transmission module 140 of the main display device. The sub display screen corresponding to the slave display device is transmitted to the corresponding slave display device (step 270). In this embodiment, it is assumed that the display screen processing module 160 of the main display device successively generates a sub-display screen corresponding to the subordinate display device arranged in the middle and an identification code corresponding to the subordinate display device arranged in the middle. a data packet, and a data packet including a sub display screen corresponding to the slave display device arranged on the right side and an identification code corresponding to the slave display device arranged on the right side, the transmission module 140 of the main display device The packet format of the wireless network protocol encapsulates the data packet generated by the display processing module 160 of the main display device, and broadcasts the network packet including the data packet to the connected subordinate display device, thus arranged in the middle and arranged right. Both the slave display devices of the party receive all the data packets generated by the display screen processing module 160 of the main display device.

在主顯示裝置的顯示畫面處理模組160透過主顯示裝置的傳輸模組140將子顯示畫面傳送到從屬顯示裝置(步驟270)後，從屬顯示裝置的傳輸模組140會接收到主顯示裝置之顯示畫面處理模組160所產生的子顯示畫面之後，主顯示裝置的顯示模組170與從屬顯示裝置的顯示模組170可以同步顯示主顯示裝置之顯示畫面處理模組160分割顯示畫面所產生之與主顯示裝置對應的子顯示畫面以及從屬顯示裝置之傳輸模組140所接收到之與從屬顯示裝置對應的子顯示畫面(步驟290)。 After the display screen processing module 160 of the main display device transmits the sub display screen to the slave display device via the transmission module 140 of the main display device (step 270), the transmission module 140 of the slave display device receives the main display device. After the sub-display screen generated by the screen processing module 160 is displayed, the display module 170 of the main display device and the display module 170 of the subordinate display device can synchronously display the display screen processing module 160 of the main display device to generate the divided display screen. The sub display screen corresponding to the main display device and the sub display screen corresponding to the slave display device received by the transmission module 140 of the slave display device (step 290).

在本實施例中，假設如「第2B圖」之流程所示，主顯示裝置的顯示模組170可以暫存顯示畫面處理模組160分割產生之與主顯示裝置對應的子顯示畫面(步驟291)，從屬顯示裝置的顯示模組170可以判斷傳輸模組140所接收到之資料封包中的識別碼是否與從屬顯示裝置自身對應(步驟293)，若是，則暫存資料封包中的子顯示畫面(步驟295)，若否，則丟棄資料封包(步驟294)，也就是不對資料封包進行任何處理。由於在本實施例中，排列在中間與右方的從屬顯示裝置都會接收到識別碼與中間對應的資料封包以及與右方對應的資料封包，所以，當排列在中間之從屬顯示裝置的傳輸模組140所接收到之資料封包中的識別碼與排列在中間之從屬顯示裝置對應時，排列在中間之從屬顯示裝置的顯示模組170可以暫存傳輸模組140所接收到之資料封包中的子顯示畫面，而當排列在中間之從屬顯示裝置的傳輸模組140所接收到之資料封包中的識別碼與排列在右方之從屬顯示裝置對應時，也就是未與排列在中間之從屬顯示裝置對應時，排列在中間之從屬顯示裝置的顯示模組170可以丟棄傳輸模組140所接收到之資料封包。相似的，當排列在右方之從屬顯示裝置的傳輸模組140所接收到之資料封包中的識別碼與自身對應時，排列在右方之從屬顯示裝置的顯示模組170可以暫存傳輸模組140所接收到之資料封包中的子顯示畫面，而當排列在右方之從屬顯示裝置的傳輸模組140所接收到之資料封包中的識別碼未與排列在右方之從屬顯示裝置對應時，排列在右方之從屬顯示裝置的顯示模組170可以丟棄傳輸模組140所接收到之資料封包。 In the present embodiment, it is assumed that the display module 170 of the main display device can temporarily store the sub-display screen corresponding to the main display device generated by the display screen processing module 160 as shown in the flow of FIG. 2B (step 291). The display module 170 of the slave display device can determine whether the identification code in the data packet received by the transmission module 140 corresponds to the slave display device itself (step 293), and if so, temporarily display the sub-display screen in the data packet. (Step 295), if not, the data packet is discarded (step 294), that is, no processing is performed on the data packet. In this embodiment, the slave display devices arranged in the middle and the right receive the data packet corresponding to the identification code and the data packet corresponding to the right side, and therefore, the transmission mode of the slave display device arranged in the middle The identification code in the data packet received by group 140 is arranged in the middle When the slave display device is corresponding, the display module 170 of the slave display device arranged in the middle can temporarily store the sub display screen in the data packet received by the transmission module 140, and the transmission module of the slave display device arranged in the middle. When the identification code in the received data packet is corresponding to the subordinate display device arranged on the right, that is, when the subordinate display device is not arranged in the middle, the display module 170 of the subordinate display device arranged in the middle may The data packet received by the transmission module 140 is discarded. Similarly, when the identification code in the data packet received by the transmission module 140 of the slave display device arranged on the right corresponds to itself, the display module 170 arranged on the right of the slave display device can temporarily store the transmission mode. The sub-display screen in the data packet received by the group 140, and the identification code in the data packet received by the transmission module 140 arranged in the right subordinate display device does not correspond to the subordinate display device arranged on the right When the display module 170 of the slave display device arranged on the right side discards the data packet received by the transmission module 140.

在從屬顯示裝置暫存相對應的子顯示畫面後，從屬顯示裝置與主顯示裝置可以同步顯示各自暫存之與自身相對應的子顯示畫面(步驟297、299)。 After the slave display device temporarily stores the corresponding sub-display screen, the slave display device and the main display device can simultaneously display the respective sub-display screens corresponding to themselves (steps 297 and 299).

如此，透過本發明，主顯示裝置所產生的顯示畫面便可以在多個顯示裝置中組合顯示。 As described above, according to the present invention, the display screen generated by the main display device can be displayed in combination in a plurality of display devices.

在上述的實施例中，若三台顯示裝置並非排列為一直線，而是以如「第3圖」的方式排列，其中，排列在左下方的顯示裝置100b為主顯示裝置，而排列在右方與左上方的顯示裝置100a、100c則為從屬顯示裝置，在各個顯示裝置的主從決定模組120選擇各個顯示裝置為主顯示裝置或從屬顯示裝置(步驟215)後，主顯示裝置在依據顯示裝置之畫面顯示尺寸分割顯示畫面為與顯示裝置對應之子顯示畫面(步驟250)時，可以如「第2C圖」所示，由主顯示裝置的偵測模組110偵測顯示裝置間之相對位置(步驟251)以及統計所偵測到之顯示裝置的數量(步驟253)，並由主顯示裝置的顯示畫面處理模組160依據所統計出之顯示裝置的數量及所判斷出之顯示裝置的相對位置分割顯示畫面為與各顯示裝置對應之子顯示畫面(步驟257)。在本實施例中，假設主顯示裝置是以磁感應開關來判斷是否與從屬顯示裝置連接，若主顯示裝置上方以及右上方各有一台從屬顯示裝置，主顯示裝置的偵測模組110可以因為上方與右方的磁感應開關連通而判斷出上方以及右方存在從屬顯示裝置，同時統計出共有三台顯示裝置，且三台顯示裝置的像素密度(Pixels Per Inch,PPI)都相同，因此，主顯示裝置的顯示畫面處理模組160會將主顯示裝置中之訊號源101所產生的顯示畫面分為與左上、左下、右方之顯示裝置對應的三個子顯示畫面，其中，左上與左下的子顯示畫面的大小為568x320、右方的子顯示畫面的大小為480x320。 In the above embodiment, if the three display devices are not arranged in a straight line, but arranged in a manner as in "3rd view", the display device 100b arranged at the lower left is the main display device, and is arranged on the right side. The display devices 100a and 100c on the upper left side are slave display devices. After the master/slave determination module 120 of each display device selects each display device as a master display device or a slave display device (step 215), the main display device displays the display. When the size display screen of the device is a sub display screen corresponding to the display device (step 250), the detection module 110 of the main display device can detect the relative position between the display devices as shown in "2C". (Step 251) and counting the number of display devices detected (step 253), and the display screen processing module 160 of the main display device is based on the counted number of display devices and the relative position of the displayed display device. The position division display screen is a sub display screen corresponding to each display device (step 257). In this embodiment, it is assumed that the main display device is a magnetic induction switch to determine whether to connect with the slave display device. If there is a slave display device above and above the main display device, the detection module 110 of the main display device may be above Judging by connecting with the magnetic induction switch on the right There are subordinate display devices on the top and the right side, and there are three display devices in total, and the pixel density (Pixels Per Inch, PPI) of the three display devices are the same. Therefore, the display screen processing module 160 of the main display device will The display screen generated by the signal source 101 in the main display device is divided into three sub-display screens corresponding to the upper left, lower left, and right display devices, wherein the size of the upper left and lower left sub-display screens is 568x320, and the right side The size of the sub display screen is 480x320.

在主顯示裝置的顯示畫面處理模組160將顯示畫面分割為與各個顯示裝置對應的子顯示畫面後，主顯示裝置的顯示畫面處理模組160可以透過主顯示裝置的傳輸模組140將分割產生之與從屬顯示裝置對應的子顯示畫面傳送給相對應的從屬顯示裝置(步驟270)。在本實施例中，假設主顯示裝置的傳輸模組140會將與排列於左上之從屬顯示裝置對應的子顯示畫面以及該子顯示畫面的顯示範圍資料「(0,0,567,319)」透過無線網路技術傳送給排列於左上的從屬顯示裝置後，再將與排列於右方之從屬顯示裝置對應的子顯示畫面以及該子顯示裝置的顯示範圍資料「(568,0,887,479)」傳送給排列於右方的從屬顯示裝置。 After the display screen processing module 160 of the main display device divides the display screen into sub-display screens corresponding to the respective display devices, the display screen processing module 160 of the main display device can generate the segmentation through the transmission module 140 of the main display device. The sub display screen corresponding to the slave display device is transmitted to the corresponding slave display device (step 270). In this embodiment, it is assumed that the transmission module 140 of the main display device transmits the sub-display screen corresponding to the subordinate display device arranged on the upper left side and the display range data "(0, 0, 567, 319)" of the sub-display screen through the wireless network. After the technology is transmitted to the slave display device arranged on the upper left side, the sub-display screen corresponding to the slave display device arranged on the right side and the display range data "(568, 0, 887, 479)" of the sub-display device are transmitted to the right side. Dependent display device.

在主顯示裝置的顯示畫面處理模組160將與從屬顯示裝置對應的子顯示畫面傳送給相對應的從屬顯示裝置(步驟270)後，主顯示裝置的顯示模組170與從屬顯示裝置的顯示模組170可以同步顯示主顯示裝置之顯示畫面處理模組160分割顯示畫面所產生之與主顯示裝置對應的子顯示畫面以及從屬顯示裝置之傳輸模組140所接收到之與從屬顯示裝置對應的子顯示畫面(步驟290)。在本實施例中，三個顯示裝置同步顯示出的顯示畫面將包含888x480個像素。 After the display screen processing module 160 of the main display device transmits the sub display screen corresponding to the slave display device to the corresponding slave display device (step 270), the display module 170 of the main display device and the display mode of the slave display device The group 170 can synchronously display the sub-display screen corresponding to the main display device generated by the display screen processing module 160 of the main display device and the sub-display device corresponding to the subordinate display device received by the transmission module 140 of the subordinate display device. The screen is displayed (step 290). In this embodiment, the display screen displayed synchronously by the three display devices will contain 888 x 480 pixels.

另外，在主顯示裝置產生顯示畫面時，主顯示裝置的顯示畫面處理模組160也可以如「第2D圖」之流程所示，判斷從屬顯示裝置的螢幕解析度(或像素密度)是否相同(步驟262)，並在從屬顯示裝置的螢幕解析度(或像素密度)不完全相同時，或是在顯示畫面處理模組無法判斷該顯示畫面的畫面解析度時，依據顯示畫面的影像尺寸、顯示畫面的清晰度指標、或上述兩者產生使從屬顯示裝置將螢幕解析度調整為特定之螢幕解析度的解析度控制指令(步驟266)，並透過傳輸模組140將所產生的解析度控制指令傳送給從屬顯示裝置，使得從屬顯示裝置調整螢幕解析度(步驟268)而使用相同的像素密度顯示相對應的子顯示畫面。在本實施例中，若三台顯示裝置的像素密度都相同，則顯示畫面處理模組160將不會產生使從屬顯示裝置調整螢幕解析度的控制指令，而若三台顯示裝置的像素密度不完全相同，例如，左上之顯示裝置100a與左下之顯示裝置100b的顯示尺寸為3.5吋、螢幕解析度為640 x 360dpi，而右方之顯示裝置100c的顯示尺寸為3吋、螢幕解析度為480 x 320dpi，則左上之顯示裝置100a與左下之顯示裝置100b的像素密度為210，右方之顯示裝置100c的像素密度為192，因此，顯示裝置100b的顯示畫面處理模組160可以依據顯示尺寸等比例計算像素密度為192之螢幕解析度，並透過顯示裝置100b的傳輸模組140傳送調整螢幕解析度為顯示畫面處理模組160所計算出之螢幕解析度之控制指令到左上方的顯示裝置100a，使得顯示裝置100a在接收到控制指令後，依據控制指令調整螢幕解析度，藉以讓三台顯示裝置使用相同的像素密度同步顯示顯示畫面。同時，在顯示畫面被顯示畫面處理模組160分割的過程中，為滿足三台顯示裝置中所顯示的顯示畫面的清晰度符合清晰度指標，顯示畫面的影像尺寸也會被顯示畫面處理模組160修改。 Further, when the main display device generates a display screen, the display screen processing module 160 of the main display device may determine whether the resolution (or pixel density) of the subordinate display device is the same as shown in the flow of the "second DD" ( Step 262), when the screen resolution (or pixel density) of the slave display device is not completely the same, or when the screen processing module cannot determine the screen resolution of the display screen, according to the image size and display of the display screen. The resolution indicator of the screen, or both, generates a resolution control command that causes the slave display device to adjust the screen resolution to a particular screen resolution (step 266), and the generated solution is transmitted through the transmission module 140. The resolution control command is transmitted to the slave display device such that the slave display device adjusts the screen resolution (step 268) and displays the corresponding sub-display screen using the same pixel density.
