Display apparatus and method for controlling power usage of the display apparatus
First Claim
1. A display apparatus having a front cover, a back cover, two long sides parallel to each other connecting the front cover and the back cover, comprising:
- a display panel;
a backlight module;
one or a combination of an accelerometer and a vibration sensor for detecting a motion parameter of the display apparatus and generating a motion parameter signal representing the motion parameter;
at least one signal processor for comparing the motion parameter with a threshold value;
a processor for controlling a state of the backlight module; and
a contact sensor on the back cover of the display apparatus for detecting a contact from a palm abutting against the back cover and generating a signal representing a gross contact area between the palm and the back cover;
wherein the at least one signal processor is configured to compare the gross contact area with a threshold contact area and generate a power off signal if the motion parameter is greater than the threshold value and the gross contact area is greater than the threshold contact area; and
the processor is configured to control the backlight module in a power off state upon receiving the power off signal.
