Abstract: An electronic device which is protected against screen breakage when dropped includes a display panel defining a through hole, a gravity sensor, a processor, and a bumper deployment mechanism. The bumper deployment mechanism includes a first elastic part and a connected rotating mechanism. The rotating mechanism includes a motor. The processor can compare a detected acceleration value with a preset acceleration value. When the detected acceleration value represents free-fall motion, which is greater than the preset acceleration value, the processor controls the motor to drive the first elastic part to pass through the through hole of the display panel and protrude from the display panel as a shock absorber.
