Abstract: The present invention provides a panel protecting device of a flat panel electronic device and a flat panel electronic device. The panel protecting device comprises: a sensor for detecting one or more of a falling speed, a falling time and a falling distance of the flat panel electronic device in a vertical direction when the flat panel electronic device is only under gravity; and a protecting means for being mounted around a panel of the flat panel electronic device. The protecting means has a rest position and a protruding position. The protecting means is accommodated in a recess of the flat panel electronic device when the protecting means is in the rest position and protrudes from the panel when the protecting means is in the protruding position. The protecting means moves to the protruding position from the rest position automatically when the one or more of the falling speed, the falling time and the falling distance is greater than or equal to a predetermined value.
