ABSTRACT:
The invention relates to a method and a device for contrast enhancement for display devices. A high-contrast representation of optical signals and/or symbols is achieved by providing a light-absorbing and/or light-deflecting background which is dark in comparison to the symbol or signal to be displayed and thus highlights said symbol or signal. The following invention enables a high-contrast representation of optical signals and symbols by the provision of a dark, light-absorbing background.
