Abstract

The invention discloses a display system, which comprises an electronic device, a display device, a power wire and two adaptors. The electronic device is used for providing an image data, and the display device displays an image according to the image data. The first adaptor is coupled with the electronic device, inserted into a first power supply socket and used for receiving the image data sent by the electronic device and a power supply transmitted by the power wire, combining an image signal and a power supply signal and transmitting the signals to the second adaptor through the power wire. The second adaptor is coupled with the display device, inserted into a second power supply socket and used for receiving the power supply transmitted by the power wire and the image data sent by the first adaptor and separating the signals to transmit the image data to the display device.

Description

technical field [0001] The present invention relates to a display system, in particular to a display system that transmits image data through power lines. Background technique [0002] With the development of information technology and multimedia technology, users often use various electronic devices to store a large amount of image data in their daily life, and then use the display device to process the image data. For example, in briefings or meetings, the moderator can use the projector to project the image data stored in the laptop computer on a large screen to facilitate discussion. [0003] Generally speaking, the electronic device outputs image data through a specific interface, and then transmits it to the display device through a transmission cable (cable), and the display device can directly display the picture (such as a liquid crystal display or project a picture (such as a projector). Analog display system Analog signal interfaces such as D-subminiatureD-sub) o...
