Abstract: The display screen of a handheld device, such as a mobile phone, personal digital assistant (PDA), tablet computer, palmtop computer, or the like, can be protected from physical shock using a protective case with a sliding display screen cover. The protective case includes a main body having an opening positioned to correspond with a position of the display screen of the handheld device. A protective door, for example a roll-top type door, is slidably coupled to the main body, so that the display screen is exposed when the door has been slid open, and covered when the door has been slid closed. The door can be coupled to the body via a track, and can be made of a transparent or semitransparent material to allow viewing of the screen when closed, while still protecting the screen from physical shock.
