Embodiment 1
[0042] An embodiment of the present invention provides an LED display authorization control method, which is executed on the LED display unit, such as figure 1 shown, including:
[0043] S110, if the preset condition is met, send an authentication request to the control unit.
[0044] A trigger module may be arranged on the LED display unit. The trigger module may be a timer, and a preset duration is set for the timer. When the timer decreases to zero or approaches zero, it is judged that the preset condition is met. Of course, the timer can also be used to record the elapsed time, and when the time reaches a certain value, it is judged that the preset condition is met. The trigger module can also be a trigger accumulator, which performs cumulative calculation according to the triggering of preset actions, and when the number of preset actions reaches a preset value, it is judged that the preset condition is met. The preset action may be an action of turning on and off the ...
