System and method for sanitizing touch screen of electronic devices

A method for sanitizing a touch screen of an electronic device, the method comprising:

• providing a first motor roller positioned on a left side of the touch screen, and providing a second motor roller positioned on a right side of the touch screen;
• setting a time interval that determines how often to sanitize a protective film overlaid on a surface of the touch screen, the protective film being divided into a first protective film and a second protective film;
• monitoring whether the electronic device is in an idle state;
• counting a time using a timer of the electronic device if the electronic device is in the idle state;
• detecting whether the first protective film or the second protective film is overlaid on the surface of the touch screen when the counted time is equal to the time interval;
• and
• upon the condition that the first protective film is overlaid on the surface of the touch screen, driving the first motor roller to move along a surface of the first protective film and sanitize the first protective film using a sanitizer, and driving the second motor roller to draw the second protective film to overlay on the surface of the touch screen;
• or upon the condition that the second protective film is overlaid on the surface of the touch screen, driving the second motor roller to move along a surface of the second protective film and sanitize the second protective film using the sanitizer, and driving the first motor roller to draw the first protective film to overlay on the surface of the touch screen.

A non-transitory computer-readable medium having stored thereon instructions that, when executed by at least one processor of an electronic device, cause the processor to perform a method for a touch screen of the electronic device, the method comprising:

• installing a first motor roller on a left side of the touch screen, and installing a second motor roller on a right side of the touch screen;
• setting a time interval that determines how often to sanitize a protective film overlaid on a surface of the touch screen, the protective film being divided into a first protective film and a second protective film;
• monitoring whether the electronic device is in an idle state;
• counting a time using a timer of the electronic device if the electronic device is in the idle state;
• detecting whether the first protective film or the second protective film is overlaid on the surface of the touch screen when the counted time is equal to the time interval;
• and
• upon the condition that the first protective film is overlaid on the surface of the touch screen, driving the first motor roller to move along a surface of the first protective film and sanitize the first protective film using a sanitizer, and driving the second motor roller to draw the second protective film to overlay on the surface of the touch screen;
• or upon the condition that the second protective film is overlaid on the surface of the touch screen, driving the second motor roller to move along a surface of the second protective film and sanitize the second protective film using the sanitizer, and driving the first motor roller to draw the first protective film to overlay on the surface of the touch screen.
