In addition, the same reference numerals may be used in the drawings to represent similar elements.
首先，請參見圖1，圖1是本創作實施例之顯示切換裝置的方塊示意圖。圖1的顯示切換裝置包括電源來源端110、電源轉換模組120、USB連接埠130、訊號輸入埠140、顯示控制器150以及複數個訊號輸出埠160。電源來源端110用以輸出第一電流A1。USB連接埠130電性連接電子裝置20，且用以傳送由電子裝置20所產生的快充訊號Fc1。電源轉換模組120耦接於電源來源端110與USB連接埠130之間，且接收第一電流A1。當電源轉換模組120偵測到快充訊號Fc1時，將第一電流A1轉換成第二電流A2，並經由USB連接埠130輸出第二電流A2至電子裝置20；相對地，當電源轉換模組120未偵測到快充訊號Fc1時，則經由USB連接埠130輸出第一電流A1至電子裝置20。電子裝置20可以為智慧型手機、平板電腦、個人數位助理(Personal Digital Assistant，PDA)或其他可攜式電子裝置等，本創作實施例並不限制電子裝置20的實施方式。 First, please refer to FIG. 1. FIG. 1 is a block diagram of a display switching device according to an embodiment of the present invention. The display switching device of FIG. 1 includes a power source terminal 110, a power conversion module 120, a USB port 130, a signal input port 140, a display controller 150, and a plurality of signal output ports 160. The power source terminal 110 is configured to output the first current A1. The USB port 130 is electrically connected to the electronic device 20 and configured to transmit the fast charge signal Fc1 generated by the electronic device 20. The power conversion module 120 is coupled between the power source terminal 110 and the USB port 130 and receives the first current A1. When the power conversion module 120 detects the fast charge signal Fc1, the first current A1 is converted into the second current A2, and the second current A2 is output to the electronic device 20 via the USB port 130; When the group 120 does not detect the fast charge signal Fc1, the first current A1 is output to the electronic device 20 via the USB port 130. The electronic device 20 can be a smart phone, a tablet computer, a personal digital assistant (PDA), or other portable electronic device. The present embodiment does not limit the implementation of the electronic device 20.
更進一步地說，電源轉換模組120包括偵測單元122與電流調整單元124。偵測單元122電性連接USB連接埠130，用以經由USB連接埠130偵測是否有接收到電子裝置20發出的快充訊號Fc1(即偵測電子裝置20是否具有快充功能)。電流調整單元124電連接於電源來源端110、USB連接埠130與偵測單元122之間。 當偵測單元122偵測到快充訊號Fc1時，控制電流調整單元124將第一電流A1轉換成第二電流A2，並經由USB連接埠130輸出第二電流A2至電子裝置20。而當偵測單元122未偵測到快充訊 號Fc1時，則控制電流調整單元124經由USB連接埠130輸出第一電流A1至電子裝置20。值得注意的是，第二電流A2係高於該第一電流A1，使得偵測單元122於偵測到電子裝置20具有快充功能時，可以高於第一電流A1的第二電流對電子裝置20進行快速充電。電源來源端110可以是電源供應器、可充電電池裝置等，本創作實施例並不限制電源來源端110的實施方式。 Furthermore, the power conversion module 120 includes a detecting unit 122 and a current adjusting unit 124. The detecting unit 122 is electrically connected to the USB port 130 for detecting whether the fast charging signal Fc1 sent by the electronic device 20 is received via the USB port 130 (ie, whether the detecting electronic device 20 has a fast charging function). The current adjustment unit 124 is electrically connected between the power source terminal 110, the USB port 130, and the detecting unit 122. When the detecting unit 122 detects the fast charging signal Fc1, the control current adjusting unit 124 converts the first current A1 into the second current A2, and outputs the second current A2 to the electronic device 20 via the USB port 130. When the detecting unit 122 does not detect fast charging When the number is Fc1, the control current adjustment unit 124 outputs the first current A1 to the electronic device 20 via the USB port 130. It is noted that the second current A2 is higher than the first current A1, so that when the detecting unit 122 detects that the electronic device 20 has a fast charging function, the second current pair electronic device that can be higher than the first current A1 20 for fast charging. The power source terminal 110 can be a power supply, a rechargeable battery device, etc., and the present embodiment does not limit the implementation of the power source terminal 110.
另外，USB連接埠130可以為USB1.0規格、USB2.0規格、USB3.0規格或USB3.1規格，本創作實施例並不限制USB連接埠130的實施方式。在本實施例中，USB連接埠130包括4支引腳，分別為引腳1、引腳2、引腳3、引腳4(未繪於圖式中)，引腳1為電源接腳(+5V)，引腳2為資料接腳(Data-)、引腳3為另一資料接腳(Data+)，引腳4為接地接腳；引腳1與引腳4用以提供電源；引腳2與引腳3用以傳輸訊號資料，以雙絞線的方式傳輸，各自使用半雙工的差動訊號並協同工作。 In addition, the USB port 130 can be a USB 1.0 specification, a USB 2.0 specification, a USB 3.0 specification, or a USB 3.1 specification, and the present embodiment does not limit the implementation of the USB port 130. In this embodiment, the USB port 130 includes four pins, which are pin 1, pin 2, pin 3, and pin 4 (not shown in the figure), and pin 1 is a power pin ( +5V), pin 2 is data pin (Data-), pin 3 is another data pin (Data+), pin 4 is ground pin; pin 1 and pin 4 are used to supply power; Pins 2 and 3 are used to transmit signal data and are transmitted in twisted pairs, each using a half-duplex differential signal and working together.
另外，本創作實施例所提出的第一電流為400mA~600mA，第二電流A2可以為800mA~2000mA。而第一電流與第二電流之電流大小可依實際狀況來進行調整，本創作對此不作限制。舉例來說，當電子裝置20透過USB連接埠130與顯示切換裝置100連接時，電源轉換模組120之偵測單元122會偵測電子裝置20是否發出快充訊號Fc1，以進一步判斷電子裝置20本身是否具有快充功能。當偵測單元122偵測到快充訊號Fc1(表示電子裝置20具有快充功能)時，控制電流調整單元124將第一電流A1調整成第二電流A2，舉例來說，將電源來源端110提供500毫安培(mA)調整為2安培(A)，並經由USB連接埠輸出2安培給電子裝置20；相對地，當偵測單元122未偵測到快充訊號Fc1(表示電子裝置不具備快充功能)時，則電流調整單元124直接將電源來源端110提供的500mA經由USB連接埠輸出給電子裝置20。總而言之，本創作實施例並不限制第一電流A1與第二電流A2的實施方式。 In addition, the first current proposed in the present embodiment is 400 mA to 600 mA, and the second current A2 may be 800 mA to 2000 mA. The current of the first current and the second current can be adjusted according to actual conditions, and the present invention does not limit this. For example, when the electronic device 20 is connected to the display switching device 100 via the USB port 130, the detecting unit 122 of the power conversion module 120 detects whether the electronic device 20 issues the fast charging signal Fc1 to further determine the electronic device 20. Whether it has a fast charge function. When the detecting unit 122 detects the fast charging signal Fc1 (indicating that the electronic device 20 has a fast charging function), the control current adjusting unit 124 adjusts the first current A1 to the second current A2, for example, the power source terminal 110. Providing 500 milliamps (mA) to 2 amps (A), and outputting 2 amps to the electronic device 20 via the USB port; in contrast, when the detecting unit 122 does not detect the fast charging signal Fc1 (indicating that the electronic device does not have In the fast charging function, the current adjusting unit 124 directly outputs 500 mA provided by the power source terminal 110 to the electronic device 20 via the USB port. In summary, the present embodiment does not limit the implementation of the first current A1 and the second current A2.
另外，訊號輸入埠140耦接於多媒體裝置10與顯示控制器150之間。複數個訊號輸出埠160分別耦接於顯示控制器150與顯示裝置30之間。因此，當顯示控制器150接收到控制訊號Tr1時，將根據控制訊號Tr1控制多媒體裝置10與顯示裝置30之間的連結。 In addition, the signal input port 140 is coupled between the multimedia device 10 and the display controller 150. The plurality of signal outputs 埠 160 are respectively coupled between the display controller 150 and the display device 30. Therefore, when the display controller 150 receives the control signal Tr1, the connection between the multimedia device 10 and the display device 30 will be controlled according to the control signal Tr1.
換句話說，顯示控制器150根據控制訊號Tr1連結其中一個顯示裝置30與多媒體裝置10。所連結的多媒體裝置10透過訊號輸入埠140傳送顯示訊號至顯示控制器150，接著顯示控制器150再根據控制訊號Tr1將顯示訊號經由訊號輸出埠160傳送至所連結的顯示裝置30。所述的多媒體裝置10可以為數位機上盒、數位天線訊號接收盒、DVD影音播放器、視訊播放器等，而顯示裝置30則可為陰極映像管(CRT)螢幕或液晶螢幕等影像輸出設備。所述的訊號輸入埠140與訊號輸出埠160為AV端子(Composite video connector，又稱複合端子)。 In other words, the display controller 150 connects one of the display devices 30 and the multimedia device 10 according to the control signal Tr1. The connected multimedia device 10 transmits the display signal to the display controller 150 through the signal input port 140, and then the display controller 150 transmits the display signal to the connected display device 30 via the signal output port 160 according to the control signal Tr1. The multimedia device 10 can be a digital set-top box, a digital antenna signal receiving box, a DVD video player, a video player, etc., and the display device 30 can be a cathode image tube (CRT) screen or a liquid crystal screen or the like. . The signal input port 140 and the signal output port 160 are AV terminals (composite video connectors).
如此一來，本創作實施例所提出之顯示切換裝置能有效達到對電子裝置的充電，若電子裝置本身具有快充功能，顯示切換裝置轉換成較大之電流(即第二電流A2)對電子裝置進行快速充電，若電子裝置本身不具有快充功能，顯示切換裝置則以一般電流(即第一電流A1)對電子裝置進行一般充電。另外，本創作實施例所提出之顯示切換裝置可對於多媒體裝置與顯示裝置之間的連結進行切換，以提升多媒體訊號傳輸及切換的方便性。 In this way, the display switching device proposed in the present embodiment can effectively achieve charging of the electronic device. If the electronic device itself has a fast charging function, the display switching device converts into a large current (ie, the second current A2) to the electronic device. The device performs rapid charging. If the electronic device itself does not have a fast charging function, the display switching device generally charges the electronic device with a general current (ie, the first current A1). In addition, the display switching device proposed in the present embodiment can switch the connection between the multimedia device and the display device to improve the convenience of multimedia signal transmission and switching.
