Abstract: An electronic device with automatic screen-cleaning function includes a film attached to a flexible display screen. The film includes heat-sensitive projections, light detection units, and heating circuit. Each light detection unit can detect a brightness value of light under the flexible display screen. The detected brightness value is evaluated against a predefined brightness value. When the detected brightness value does not equal the predefined brightness value, at least one electrical resistance heater element is controlled to generate heat, causing one of projections to bulge from the film. The bulging projection pushes out the flexible display screen, thus making dust or other external contaminant fall from the flexible display screen.

Abstract: An exemplary computer mouse which is proofed against the ingress of contaminants includes a housing, a bottom cover, a left button, a right button and a middle button bracket. The middle button bracket includes a dust-proof block and a number of elastic components. The dust-proof block includes a raised portion. A middle button hole is defined between the left button and the right button, the raised portion is received in the middle button hole, and a sidewall of the raised portion is contact with or abuts a sidewall of the middle button hole. The number of the elastic components are arranged between the dust-proof block and the bottom cover. The elastic components keep a top surface of the raised portion substantially flush with outer surfaces of the left and right buttons when no button is pressed and flush with the outer surface of the button which is pressed.
