摘要:
An autostereoscopic display lens arrangement comprises an array (9) of parallel lenticular lenses (11), wherein the lens array comprises first and second materials of different refractive indices (60,62) sandwiched between planar substrates, with the interface between the first and second materials defining the lens surfaces. The first material has a refractive index n1, the lens array has a lens pitch p and the lenticular lenses have a radius of curvature at their centre of R, and the lenses satisfy n1 (p/2R)>0.6. This arrangement gives reduced banding and loss of intensity at steep angles when used in an autostereoscopic display.

A switchable autostereoscopic display device comprises a first LED display panel, an array of non-switchable lens elements and a second LED display panel. This arrangement avoids the need for a switchable lens array to implement a switchable 2D/3D display. The first LED display panel can simply be turned off so that the lens array does not play a role in generating a 3D output. The second LED display panel then produces the desired 2D image.

A multi-view display device comprises a pixellated display panel and a backlight comprising an arrangement of light sources (30), wherein each light source, when turned on, illuminates an associated region of pixels of the display panel. A display controller is adapted to control the pixellated display panel and the arrangement of light sources such that a partial display output is provided comprising simultaneously a set of at least three 2D views with no repetition of individual 2D views. This arrangement provides an output with controlled illumination direction of the pixels so that view repetitions are avoided. The output can be a single cone of views, and the location from which the cone of views can be viewed depends on the relationship between the light sources of the backlight which are activated and the display panel.

The invention provides a collimator comprising a first collimator face, a second collimator face, and a stack region. The stack region comprises a first layer having a first prismatically shaped top face with a plurality of 1D arranged first prisms having first prism axes, and a second layer having a second prismatically shaped top face with a plurality of 1D arranged second prisms having second prism axes. The first and second prism axes are in a crossed configuration. In a direction from the first collimator face to the second collimator face, the index of refraction of material upstream of the first prismatically shaped top face is larger than that of material downstream of the first prismatically shaped top face, and the index of refraction of material upstream of the second prismatically shaped top face is larger than that of material downstream of the second prismatically shaped top face.

The invention relates to a solid state lighting strip (100) for mounting in or on a panel support element (210) of a modular panel system (200). The strip comprises a plurality of solid state lighting elements (110, 110′), a light extraction layer (120) and a glare reducing layer (130). The solid state lighting elements are arranged such that the light emitted by said elements is coupled into the glare reducing layer via the light extraction layer. The solid state lighting strip (100) can be used as part of alighting system, a panel support element (210) and a modular panel system (200).

An autostereoscopic display device comprises a display panel (3) having an array of display pixel elements (5) for producing a display, the display pixel elements being arranged in rows and columns. An imaging arrangement (9) directs the output from different pixel elements to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement comprises first and second polarization-sensitive lenticular arrays (50,52), wherein the light incident on the imaging arrangement is controllable to have one of two possible polarizations, and wherein each of the two possible polarizations gives a different 3D mode. These multiple modes can be used to increase the resolution, or increasing the number of views, or provide additional functionality to the display device.

A switchable autostereoscopic display device includes a display panel having an array of display pixels for producing a display, and a lens arrangement for directing the output from different pixels to different spatial positions to enable a stereoscopic image to be viewed. The lens arrangement is in a plane parallel to the display panel and includes an electrically switchable LC layer which defines a lens pattern or a lens replica pattern. The LC alignment of the LC layer is electrically switchable such that the lens arrangement is switchable between 2D and 3D modes. In the 2D mode, the LC alignment is in a first direction substantially within the plane of the lens arrangement; and in the 3D mode, the LC alignment is in a second, perpendicular direction also substantially within the plane of the lens arrangement. The light output of the display panel is polarized in the second direction.

The invention relates to a luminaire that enables the use of more sparsely distributed light sources, having a uniform fixture surface brightness and good color mixing. The luminaire comprises first and second light guide layers (10, 11) optically coupled together by at least one optical coupler (12a, 12b), which allows the passage of light from the first (10) to the second light guide layer (11). The luminaire also comprises a plurality of light sources (16a, 16b), each of which being arranged such that light emitted by the light source (16a, 16b) is coupled into the first light guide layer (10) at an interface surface (17)arranged substantially perpendicularly to a longitudinal axis of the first light guide layer (10). The luminaire further comprises a scattering element (14) adapted to cause light to be emitted from an emitting surface of the second light guide layer (11). By providing two optically coupled light guide layers (10, 11), one for receiving light emitted by the light sources (16a, 16b) and the other for emission, greater opportunity for dispersion and color mixing of the light is provided.
