Beschreibung
Zusammenfassung:	The invention relates to a method of preventing a light leakage of environmental light to a first display of an electronic device through a second display of the electronic device. The first display and the second display are arranged on opposite sides of the electronic device, and a single backlight guide is used for providing a backlight to the first display and to the second display. The method comprises determining whether a light leakage protection mode is to be entered. In case it is determined that a light leakage protection mode is to be entered, the second display is caused to present an essentially black screen. The invention relates equally to a corresponding device and to a corresponding software program product.
