Display device configured to simultaneously exhibit multiple display modes

摘要

A display comprises a parallax optic (2), such as a combined parallax barrier and lens array, and a pixellated display device (1). The pixels of the display device (1) are arranged as groups cooperating with a parallax element (4) of the parallax optic (2). Each group comprises a first pixel (A) aligned with the centre of the parallax element (4), second and third pixels (B, C) on either side of the first pixel (A), and fourth pixels (D) shared with adjacent groups and disposed outside the second pixels (B, C). The parallax elements (4) make the different pixels of each group visible in different viewing regions. A control arrangement selects regions of the display and selects different combinations of the pixels of each group for image display within respective regions so as to provide simultaneously-present different viewing modes having different viewing range characteristics.

1. A display comprising: a parallax optic having a plurality of parallax elements; a display device having a plurality of pixels arranged as groups, each of which cooperates with the parallax elements of the parallax optic such that corresponding pixels of the groups are viewable in respective different viewing regions; and a control arrangement configured to select arbitrary first and second spatial regions of the display device, the spatial regions each comprising a plurality of topographically connected pixels, and the control unit is configured to simultaneously select, for image display, a first combination of the pixels of each group of the first spatial region and a second combination of the pixels, different from the first combination, of each group of the second spatial region to provide simultaneous first and second display viewing modes of different viewing range characteristics,
wherein the display has multiple groups of pixels, each group of pixels being a different subset of the plurality of pixels of the display; and wherein each group comprises a first pixel aligned with a central axis of a cooperating parallax element, second and third pixels each directly adjacent to the first pixel and on opposite sides of the first pixel, and at least one fourth pixel directly adjacent to and on an opposite side of the second or third pixel from the first pixel, wherein the fourth pixel is aligned with an opaque region in the parallax optic adjacent to the cooperating parallax element.
