ABSTRACT:
The present invention relates to an image displaying device which can control the usage of the image displaying device according to some predetermined time-related events. The image displaying device comprises a screen for displaying an image frame, an image display circuit for displaying image signals on the screen to form the image frame, a clock circuit for generating clock signals containing time of day information in it, a control circuit for controlling usage of the image display circuit according to the clock signals, and an on-screen display circuit electrically connected between the control circuit and the image display circuit for displaying a warning message on the screen through the image display circuit to prevent the image display circuit from normally displaying the image signals on the screen. When the control circuit detects one of the time-related events, the control circuit will control the on-screen display circuit to display the warning message on the screen to prevent the image display circuit from displaying the image signals on the screen in a normal manner.
