The present disclosure generally relates to techniques and user interfaces for transitioning between a standard display mode and a low power display mode.

A projector including a controller circuit and a shuttle wheel, and an operating method are provided. The controller circuit controls an operation of the projector. The shuttle wheel is disposed on an upper cover of the projector. The controller circuit controls whether the projector enters an on screen display mode according to an operation method of the shuttle wheel. When the projector enters the on screen display mode, the controller circuit controls the projector to project a first menu on a screen. According to the operation method of the shuttle wheel, the controller circuit selects an adjustment item of the projector on the first menu. When the projector does not enter the on screen display mode, the controller circuit controls the projector to project a second menu on the screen. According to the operation method of the shuttle wheel, the controller circuit sets the adjustment item on the second menu.
