Abstract
The aim of the invention is to largely prevent certain influences from distributing the luminance of an image that can be reproduced on a panel of a flat screen. To this end, light-permeable parts are arranged between a sensor and a back light illuminating the panel from the rear, the ageing and/or temperature properties of said light-permeable parts essentially corresponding to those of the light-permeable parts of the panel.
