Abstract (en)
A method and system for protecting the display devices against the pixel burn-in problem is described. The method can also be applied to all set-top boxes and display devices that need similar protection. The method provides a screen saving method by calculating the OSD percentage value and according to changes in this value and activating the screen protection procedure. These percentage values are used to determine the static OSD during a pre-determined time period. If OSD is perceived as static during the period, pixel burn-in protection methods are activated. The method is independent from user actions.
