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 9):
A method of operating a display device having a privacy mode and a public mode, wherein the display device comprises a display panel, a backlight arrangement, wherein the backlight arrangement is arranged to illuminate the display panel and a light blocking arrangement arranged to selectively block the light which is directed in a lateral output direction from the display panel, wherein the light blocking arrangement is 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:\n configuring the display in one of the privacy mode and the public mode, wherein the configuring depends on the spectrum of light incident on the light blocking arrangement; using the backlight arrangement to provide a first, non-visible, light output,\n wherein the light output is the light stimulus for inducing switching of the light blocking elements towards an opaque state to implement the privacy mode, \n wherein the light blocking arrangement blocks the laterally directed light; \n using the backlight arrangement to provide a second visible light output; removing the light stimulus from the light blocking arrangement; and using the backlight arrangement to provide a third output for inducing switching of the light blocking elements to a transparent state, wherein the transparent state implements the public mode, wherein the light blocking arrangement does not block the laterally directed light.
