Abstract:
A display device has a light blocking arrangement for selectively blocking light which has or would be emitted at large lateral angles. The display can be configured so that light reaching these elements is either allowed to reach the viewer or is blocked from reaching the viewer. This means that a public viewing mode can be chosen or a private viewing mode. The light blocking elements are controlled optically in order to simplify the construction and control.

Claim (Index 1):
A display device having a privacy mode and a public mode, comprising:\n a display panel; a backlight arrangement, wherein the backlight arrangement is arranged to illuminate the display panel; and a light blocking arrangement,\n wherein the light blocking arrangement is arranged to selectively block light, \n wherein the light is directed in a lateral output direction from the display panel, \n wherein the display blocks the laterally directed light using the light blocking arrangement in the privacy mode, wherein the display does not block the laterally directed light in the public mode, wherein the light blocking arrangement comprises elements formed from a photochromic material, wherein the blocking function of the photochromic material is dependent on a light stimulus of a particular wavelength incident on the light blocking arrangement, wherein the backlight arrangement has a first, non-visible, light output which is the light stimulus for inducing switching of the light blocking elements to an opaque state, wherein the backlight arrangement has a second, visible, light output, wherein the backlight arrangement has a third output for inducing switching of the light blocking elements to a transparent state.
