Display system, display device, and HDMI dongle
A display system includes a display device and an HDMI dongle electrically connected to the display device. The display device includes a first transmission interface, a first control module, and a power supply module. The HDMI dongle includes a second transmission interface and a second control module. The first and the second transmission interfaces include transmission pins corresponding to each other. The first control module detects voltage of one pin to obtain matching state between the display device and the HDMI dongle and outputs an enabling signal. When the HDMI dongle matches the display device, the enabling signal controls the power supply module to transmit the power supply signal to the second control module through the first and the second transmission interfaces for charging the second control module. When the HDMI dongle does not match the display device, the power supply module is not transmitted to the second control module.
