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.

1-49. (canceled)
A device for contrast enhancement for display devices, comprising
- a focusing optical device including a lens and/or a mirror arrangement,
- a diaphragm with at least one aperture, and
- a light disposal element for deflecting and/or absorbing light, wherein the optical device is arranged such that it focuses incident light and directs it through the at least one aperture to the light disposal element for deflecting and/or absorbing extra light.
A device for contrast enhancement for display devices, comprising
- a light scattering device including a divergent lens and/or a mirror arrangement, and
- a light disposal element for deflecting and/or absorbing light, wherein the light scattering device directs incident light to the light disposal element for deflecting and/or absorbing light.
A method for contrast enhancement for display devices intended for use in incident light comprising the steps of:
- focusing and/or scattering the incident light by a lens and/or mirror arrangement, and
- creating a dark background by absorbing and/or deflecting the incident light.
