摘要： An apparatus and method for controlling a video signal processing apparatus having a browser feature to protect a display device associated with the apparatus against the premature aging effects of screen burn due to an idle display when the browser feature is activated. The method includes the steps of detecting a first user input to a video apparatus, determining whether the first user input activates a browser feature of the video apparatus, and controlling the operation of the apparatus to reduce the screen burn. The operation can include setting a display parameter for the video apparatus to a first predetermined level responsive to determining that the first user input activates the browser feature, or determining an idle time and inactivating the browser feature if the idle time exceeds a predetermined period of time.

摘要： Screen burn on televisions having Internet browser capability is avoided by removing the conventional static icons such as toolbars and buttons from the default browser and replacing their functions with keyboard keys. The invention is especially useful in projection televisions and with keyboards which have keys assigned to browser functions. Favorite URLs can be mapped to a favorite key by holding down the favorite key while a favorite web page is displayed.
