Abstract
A portable electric apparatus (1) has a display (6) of the type comprising a liquid crystal layer. The display has an active state for presenting visual information in response to a supply of electric energy to the liquid crystal layer. The display also has an inactive state, in which less electric energy is supplied to the liquid crystal layer and less visual information consequently is presented. The apparatus (1) also has a proximity detector (20) for detecting the presence of an object in proximity with the apparatus and in response causing the display (6) to enter its inactive state.
