CA 2329189

The present invention provides light diffusing elements that make intimate optical contact with other optical elements and provides useful function in addition to diffusion. In one particular embodiment, the diffuser is self- adhering, thus facilitating lamination of optical components on opposite sides of the diffuser. The self-adhering diffuser also exhibits useful diffusing properties including polarization preservation, low backscattering, controllable viewing angle, and the like. The diffuser is particularly suited for use in single and no polarizer display applications.

Cette invention se rapporte à des éléments diffusant la lumière qui établissent un contact optique intime avec d'autres éléments optiques et qui remplissent une fonction utile en plus de la diffusion. Dans un mode de réalisation particulier, un tel diffuseur est auto-adhésif, ce qui facilite la stratification des composants optiques sur les côtés opposés du diffuseur. Ce diffuseur auto-adhésif possède également des propriétés de diffusion utiles telles qu'une conservation de la polarisation, une faible rétrodiffusion, un angle de visualisation régulable, notamment. Ce diffuseur est particulièrement approprié pour servir dans des applications d'afficheurs à un seul polariseur et sans polariseur.
