Abstract: The disclosure is directed towards systems and methods for dimming an alarm clock with three displays. An alarm clock can include three displays each positioned on a different side of the alarm clock to allow the alarm clock to be read from different vantage points. In some implementations, the alarm clock can include a front display, a right side display, and a left side display. Each display can have multiple brightness settings. Each display also can have a respective dimming button to allow a user to select a desired brightness level. In some implementations, the dimming button for the front display can serve as a master dimming button by controlling the brightness of all three of the displays, while the right side dimming button and the left side dimming button control only the brightness setting for the right side display and the left side display, respectively.
