Abstract
The present invention provides a display apparatus with display screen burn-ins prevention functions, comprising a calculation module configured to identify a set of to-be-adjusted grayscale edge pixels corresponding to a static display part in a detection area based on a plurality of sets of grayscale edge pixels identified from a plurality of images in the detection area at different time instances; a determination module configured to determine whether the set of to-be-adjusted grayscale edge pixels is an empty set; and an adjustment module configured to adjust intensity levels of the to-be-adjusted grayscale edge pixels when the determination module determines that the set of to-be-adjusted grayscale edge pixels is not an empty set.
