摘要： According to an example, a display having a display surface may comprise a backlight, a collimator, and a scattering layer. The backlight may emit light towards the display surface, the light being narrowed by the collimator. The collimator may be located between the display surface and the backlight and the scattering layer may be between the display surface and the collimator. The scattering layer may be selectively operable between a diffuse state in which light traveling through the scattering layer is scattered and a non-diffuse state in which the direction of travel of the light traveling through the scattering layer is substantially unaffected.
