Abstract:
A digital photo frame having power saving functions includes a display panel, a power generation unit for switching a system power according to a power control signal, a user detection unit installed on the display panel for detecting whether a user exists within a specific range to generate a user detection signal, a central processing unit for adjusting backlight intensity of the display panel when the system power is provided by the power generation unit according to the user detection signal and for generating a power switch-off signal when the backlight intensity of the display panel is turned off according to the user detection signal, and a power control unit for generating the power control signal to switch off the system power when the backlight intensity of the display panel is adjusted to be switched off according to the power switch-off signal.
