Display panel operating system

Abstract

A display panel operating system includes an isolation module, a first control module, and a second control module. The first and second control modules are electrically connected to a first display panel and a second display panel, respectively, and transmit and receive a first input / output signal and a second input / output signal for control purposes. They are also electrically connected to a first terminal and a second terminal of the isolation module to transmit and receive the first and second input / output signals, respectively. When a second power-on option of the first display panel is triggered, the first control module receives the first input / output signal and converts it into the second input / output signal via the isolation module, enabling the second control module to start a corresponding second device based on the second input / output signal.

Claims

1. A display panel operating system, applicable to a first display panel of a first device and a second display panel of a second device, comprising: an isolation module including a first terminal and a second terminal, and used for bidirectional logic potential voltage conversion of signals at the first terminal and the second terminal; a first control module electrically connected to the first display panel, transmitting and receiving a first input / output signal to control the first display panel, and also electrically connected to the first terminal of the isolation module to transmit and receive the first input / output signal; and a second control module electrically connected to the second display panel, transmitting and receiving a second input / output signal to control the second display panel, and also electrically connected to the second terminal of the isolation module to transmit and receive the second input / output signal; wherein, The first display panel includes a first power-on option corresponding to the first control module and a second power-on option corresponding to the second control module. When the first power-on option is triggered, the first control module starts the corresponding first device by means of the first input / output signal from the first display panel. When the second power-on option is triggered, the first control module receives the first input / output signal from the first display panel and converts the first input / output signal into the second input / output signal via the isolation module, so that the second control module starts the corresponding second device according to the second input / output signal.

2. The display panel operating system as described in claim 1, wherein, The second display panel includes a second power-on option corresponding to the second control module and a first power-on option corresponding to the first control module. When the second power-on option is triggered, the second control module starts the corresponding second device by means of the second input / output signal from the second display panel. When the first power-on option is triggered, the second control module receives the second input / output signal from the second display panel and converts the second input / output signal into the first input / output signal via the isolation module, so that the first control module starts the corresponding first device according to the first input / output signal.

3. The display panel operating system as described in claim 1, wherein, The first input / output signal includes a first power signal, a first transmission signal, a first reception signal, and a first ground signal. The second input / output signal includes a second power signal, a second transmission signal, a second reception signal, and a second ground signal. The isolation module includes a first optocoupler and a second optocoupler. The first optocoupler includes an anode that receives the first power signal, a cathode that receives the first transmission signal output from the first control module, an emitter that receives the second ground signal, and a collector that transmits the second reception signal input to the second control module. The second optocoupler includes the anode that receives the second power signal, the cathode that receives the second transmission signal output from the second control module, the emitter that receives the first ground signal, and the collector that transmits the first reception signal input to the first control module.

4. The display panel operating system as described in claim 1, wherein, The first device is a washing machine, and the second device is a dryer.

5. The display panel operating system as described in claim 1, wherein, The first display panel also includes a first function option corresponding to the first control module and a second function option corresponding to the second control module. When the first function option is triggered, the first control module controls the corresponding first device through the first input / output signal from the first display panel. When the second function option is triggered, the first control module receives the first input / output signal from the first display panel and converts the first input / output signal into the second input / output signal through the isolation module, so that the second control module controls the corresponding second device according to the second input / output signal.
