Patent ID: 7423796

Claim:
A directional display apparatus comprising: a spatial light modulator comprising an array of pixels; and a lens array having a structure which repeats at a predetermined pitch, wherein the directional display apparatus is arranged such that, in respect of sections of the lens array at said predetermined pitch, each respective section is operable for directing light from at least one pixel aligned with the respective section into at least one nominal viewing window, and each respective section is also operable for directing light from at least one adjacent pixel aligned with a section adjacent the respective section into the same at least one nominal viewing window, wherein the lens array has at least one lens surface operable for directing light from at least one pixel aligned with the respective section into said at least one nominal viewing window, and the directional display apparatus further comprises a deflection element arranged to deflect a portion of the light from at least one pixel aligned with said adjacent section passing through each respective section of the lens array by an amount which causes said at least one lens surface to direct said light from said at least one pixel aligned with said adjacent section into said same at least one nominal viewing window.
