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.

Claims

1. A digital photo frame (DPF) comprising:

a power management unit connected to a power source, configured for distributing power from the power source to the DPF;

a display panel comprising a reflective structure, wherein, the reflective structure is a reflective film covering the display panel, the reflective film comprises a multilayer structure and one layer except the surface of the reflective film is plated with reflective material;

a backlight unit connected to the power management unit, configured for illuminating the display panel after being turned on;

a touch sensing unit configured for detecting whether the DPF is touched by a person and producing a touch signal when the DPF is touched by the person; and

a processing unit connected to the touch sensing unit, configured for controlling the power management unit to discontinue power from the power source to the backlight unit once receiving the touch signal;

wherein, the display panel reflects an image of the person via the reflective structure when the backlight unit is turned off due to the power being discontinued to the backlight unit.

2. The DPF of claim 1, wherein the reflective material is selected from the group consisting of aluminum, bronze, and silver.
