Display device and display system

This creation is related to display devices and display systems, and particularly relates to display devices and display systems that use Power over Ethernet (POE).

In today's society, how to quickly transmit information becomes an important issue, and the most effective and convenient way to deliver information is to directly visualize the information and display it in the display device of the display system.

In order to effectively provide different types of information, various display systems for different purposes have been proposed, such as an indoor electronic signage system installed in department stores for playing promotional information or a large-sized outdoor electronic device for outdoor broadcasts or advertisements. Kanban system. Further, there are currently display devices available for input operation on the market (such as a touch screen, a display device with buttons, or a display device with a card reader).

The display system equipped with the aforementioned display device has an interactive function and is more widely used, such as a multimedia service machine installed in a convenience store, an automatic teller machine, a navigation machine installed at the entrance of the building, and a medical care information display system installed in the hospital ward. Or a doctor's consultation information display system installed in the hospital.

However, in the current display system, the display device is mostly disposed at the same position as the host, and this setting mode not only causes inconvenience in management and maintenance (when multiple display systems are respectively When setting different locations, the administrator must go to the setting location of each display system to maintain or manage each host), which increases the risk of the host installed in the open space being destroyed or stolen. In order to solve the aforementioned problems, a display system configuration as shown in FIG. 1 has been proposed.

Please refer to FIG. 1 , which is a schematic diagram of a conventional display system. As shown in FIG. 1, the conventional display system 1 includes a host 10 and a display device 12 that are separately disposed.

The transmission line not only increases the cost of laying the transmission line, but also causes the connection line between the host 10 and the display device 12 to be too complicated and difficult to manage. (2) The effective distance of the general transmission line is too short (such as the universal serial bus transmission line and the high resolution multimedia interface (HDMI) transmission line are only 5 meters effective distance), so that the host 10 and the display The upper limit of the set distance between the devices 12 is limited to the effective distance of the transmission line and is too short. (3) The conventional display device 12 needs to externally connect the power source 16 to obtain power required for operation, so that the setting position of the display device 12 is limited by the position of the power source 16.
