Abstract
A digital photo frame (DPF) includes a power source, a power management unit, a display panel, a backlight unit, a touch sensing unit and a processing unit. The display panel includes a reflective structure. The power management unit is used to manage the power supply from the power source to the DPF. The touch sensing unit is used to produce a touch signal when detecting the DPF is touched by a user. The processing unit receives the touch signal, and controls the management unit to discontinue the power from the power source to the backlight unit, therefore display panel reflects images via the reflective structure.
