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.
