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.
