Problems solved by technology
Although this possible solution has the advantage of reducing the risk of overloading the power distribution network, it also has the disadvantage that it may require additional hardware to control the powering up of the display devices at different times from each other, increases costs, and may not be suitable for use in all contexts
However, this possible solution has the disadvantage of risk of human error and increased labor costs

Embodiment Construction
[0034] figure 1 A prior art method of powering on multiple display devices is schematically represented. exist figure 1 In the graph of , time measured in seconds is plotted on the x-axis or abscissa and power measured in watts is plotted on the y-axis or ordinate. According to this prior art method, the plurality of display devices are at time t 1 power on, which results in a substantial increase in the power consumption of the multiple display devices, as figure 1 dP in 1 shown. Such as dP 1 Such large increases in power consumption can burden the distribution network, which may have undesirable knock-on effects on other loads attached to the same distribution network.
[0035] figure 2 An embodiment of a network 1 of display devices 10 is schematically shown. The network 1 includes a plurality of display devices 10 a , 10 b , 10 c , . . . 10 n , . In the illustrated embodiment, the plurality of display devices 10a, 10b, 10c, . . . 10n, . However, in other possibl...

The invention provides a method for powering on a plurality of display devices. Each display device at least comprises a main processor and a visual display unit under the control of the main processor. The main processor may include, for example, a central processing unit mounted on a main circuit board of the display device. The method comprises at least energizing the main processors of at least a majority of the display devices at a first time (t2) and energizing the visual display units of the majority of the display devices at a later time (tn). The invention also provides a method of powering off such a plurality of display devices by performing a similar sequence of operations in an opposite chronological order, and a network comprising such a plurality of display devices and a server communicatively connected with each of the plurality of display devices, wherein the server is configured to power on or power off the respective host processor of the same display device at a time different from power on or power off of the visual display units of at least a majority of the display devices. These methods and such a network have the advantage of dispersing the total variation (dP1) of the electrical power consumed from the power distribution network over a limited period of time (dt), thereby reducing the burden imposed on the power distribution network.
Description
[0001] The present invention relates to a method of powering on a plurality of display devices according to claim 1, a method of powering off a plurality of display devices according to claim 7, and a device comprising a plurality of display devices according to claim 12. The internet. Background technique [0002] Large public facilities such as shopping malls, railway stations, airports, etc. may contain a large number of display devices for displaying advertisements, arrival and departure information, maps of the facility, etc. Often, these display devices are networked together to display similar or related information in multiple different locations simultaneously. From time to time, at least some of these display devices may also be interactive, allowing a user to confirm the location of a restaurant or a particular type of store within the facility, for example, through interaction with a touch screen. Typically these display devices have a large surface area (eg 2 squ...
