Abstract

Display system for guiding, advising or evacuating, in which system people are guided, advised or warned with display means, such as with display apparatuses, which display apparatuses comprise information, such as images or signs. The display apparatus (1) comprises a display panel (2), which is an e-paper display, such as an electrophoretic display panel or a display panel of that type, for which a lighting arrangement is arranged, which lighting arrangement comprises a light source (3) and a photoconductor layer (4) arranged on the display surface of the display panel or in front of it, which photoconductor layer is fitted to conduct the light of the light source to the display surface of the display panel. The invention also relates to a display apparatus.

Claims
