Abstract:
An electronic display device detects whether a user is in front of a display via a camera according to a first frequency in a working mode of the electronic display device. If the electronic display device detects that the user is not in front of the display for a first predefined time period, the electronic display device enters a power saving mode by turning off the display. The electronic display device detects whether the user is in front of the display again via the camera according to a second frequency in the power saving mode. The electronic display device reduces the second frequency after the user is not in front of the display for a second predefined time period. The electronic display device enters the working mode by turning on the display when detecting that the user is in front of the display again.
