| Zusammenfassung: | A light guide module (
10
) for use in a flat panel display (
21
) comprises a light guide pipe (
20
) having a light emitting surface (
21
), and a light incident surface (
25
) orthogonal to the light emitting surface. A light diffusion arrangement (
30
) is deployed over the light emitting surface and includes organic scattering balls (
31
) homogenously mixed within a bonding agent (
33
). At least a light source (
60
) is arranged adjacent the light incident surface to project light beams into the light guide module. |
