Abstract

A display element comprising a light-emitting diode and a display field that is backlit by the light-emitting diode. In said element, the beam path of the light in the display element passes through at least two light scattering elements.

Claims

1-7. -7. (canceled)

8. A display element comprising:

a light-emitting diode;

a display field, the light-emitting diode emitting light along a beam path and the light-emitting diode being operable to backlight the display field; and

at least two light-scattering elements, the beam path of light emitted by the light-emitting diode passing through the at least two light-scattering elements.

9. The display element as claimed in claim 8, wherein at least one of the light-scattering elements is a diffusing screen.

10. The display element as claimed in claim 9, wherein the at least one light-scattering element an application of paint applied to the display field.

11. The display element as claimed in claim 8, wherein one of the light-scattering elements is adjacent to the light-emitting diode and is a lens.

12. The display element as claimed in claim 11, wherein the lens is a cylindrical lens.

13. The display element as claimed in claim 8, wherein an extent of the beam path extends between the light-scattering elements and is surrounded by reflective walls.
