Abstract: In one aspect an arrangement for data transmission between an image source and an image reproducing system is build, with digital R/G/B video signals being able to be fed to the image reproducing system via an R/G/B path pair in each instance and a communication signal. Measures are proposed which reduce the transmission time required to transmit large data volumes in a communication operating mode.

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.
