New description: [New technical field] The present invention relates to a display device, and more particularly to a display device capable of charging an external device during standby. [Previous Art] Referring to FIG. 1 , a liquid crystal display device 9 includes a power supply circuit 9 , a main power converter 92 , a standby power converter 93 , a backlight module 95 , a video module 96 , and a microprocessor 98 . . The power circuit 91 has a filter circuit, a rectifier circuit and a power factor controller (PFC). The filter circuit is an electromagnetic interference that receives the mains and filters out the alternating current. The rectifier circuit converts the alternating current voltage into a direct current voltage, and the power factor is corrected by the power factor controller. It is sent to the main power converter 92 and the standby power converter 93. The main power converter 92 performs power conversion in the power on mode to convert the DC voltage to the main power supply +24V and +12V output, and stops the power conversion in the standby mode without outputting the main power supply +24V and +12V. The main power supply +24V is converted into a high-voltage AC voltage through the inverter of the backlight module 95 to illuminate the backlight source of the liquid crystal display; the main power supply + 12V is an audio amplifier and audio-visual processing circuit that supplies power to the audio-visual module 96; The standby power converter 93 can perform power conversion to convert the DC voltage to the standby power +5V output regardless of the power-on mode or standby mode (stand by), and the standby power supply +5V is powered to the microprocessor 98, enabling micro The processor 98 can accept operations even in the standby mode. The microprocessor 98 is configured to monitor whether to press the power button on the remote controller or the control panel, and then send the power switch signal PS to control the power supply circuit 91 to switch between the open 3 M435692 and the standby mode; for example, the microprocessor 98 is in the power supply mode of the boot mode. The circuit 91 DC power supply is supplied to the main power converter %, so that the main source converter 92 performs power conversion and outputs the main power source +24v and +]2v; in the standby mode, the microprocessor 98 controls the power supply circuit to supply power to: The converter 92 causes the main power converter 92 to stop the power conversion and turn off the action of the impact module 96. However, as the number of portable electronic homes in the home increases, so does the demand, which is supposed to be! ^ π Female agency does not sigh 9 on the standard to face the external device charging 'needs - set whether the power supply in the boot mode or standby mode can solve the problem. Case" ', [new content] Therefore 'this new type The purpose is to provide a display device that cannot supply power to an external device in standby mode. Therefore, the display device of the present invention is electrically connected to an external device, and the display device is internally supplied in a power-on mode - the power is turned on and the standby power is supplied in a standby mode, and the power source and the standby power source are adapted to charge the external device. The display device includes a standard interface for transmitting a data signal and having a power pin for transmitting power, and an input module for accepting a user operation to generate a pair of operation and shutdown devices of the display device; ―Electric^ Connects and transmits power to the power supply circuit of the power connector of the standard interface. The control module includes a switching circuit for selecting or outputting the standby power source or the power-on power according to the operation command, and receiving a signal output terminal of the switching circuit for receiving the operation command, and a standby power terminal for receiving the standby power source, Receiving the power-on power terminal of the power-on power source and the power-output terminal, the power wheel output terminal is electrically connected to the power supply circuit and the switching circuit, and the power source selected by the switching circuit is powered by the power supply circuit and the standard interface The pin is transmitted to the external device. Preferably, the input module is a wireless receiver or a button that receives an on/off operation command to cause the display device to be in an on/off mode. The standard interface is - HDMI interface, - DVI interface or a interface. In one embodiment, the power supply circuit further has a protection circuit for avoiding short circuit or excessive transmission power. The control module further has a monitoring end, and the protection circuit further has an output pin connected to the monitoring end, and the protection The circuit sets a predetermined value. If the signal value outputted by the power output terminal of the control module exceeds a predetermined value or does not reach a predetermined value, the protection circuit determines that the abnormality is abnormal, and then transmits the monitoring signal of the abnormal state to the control module. Monitoring side. In another embodiment, the control module can be integrated with a protection circuit that avoids short circuit or excessive power transmission at the front end of the power output. The effect of the display device for charging an external device during standby is that it not only solves the problem that the standby mode cannot be powered through the standard interface, but also automatically switches the power of the on/standby power supply with the user's power on/off operation, and no additional menu is needed. Operation can save users' operating time.
