摘要： The invention relates to an illumination system (10, 20, 30) for illuminating a display device (40) and to a display device (40). The illumination system comprises a light- mixing chamber (50) which comprises a light-exit window (52), a rear wall (54) which is situated opposite the light-exit window (52), and edge walls (56, 58) which extend between the light-exit window (52) and the rear wall (54). A surface (55) of the rear wall (54) is substantially specularly reflective for specularly reflecting light impinging on the surface of the rear wall and having a relatively large angle of incidence with respect to an axis perpendicular to the rear wall. The illumination system further comprises a light source (60, 62) and a plurality of light out-coupling elements (70). The light source emits light into the light-mixing chamber in a direction substantially parallel to the light-exit window. The illumination system further comprises an angularly reflective filter (80) applied at the light- exit window. The angularly reflective filter is constituted of a plurality of substantially transparent layers (81, 82, 83, 84), each layer having a substantially uniform thickness. Each set of two adjacent layers (81, 82, 83, 84) of the angularly reflective filter has different refractive indexes.

摘要： An adaptively controllable backlight system (1), having a plurality of individually controllable light-sources (3a-d) arranged on a backlight panel (2) to emit light in a direction substantially normal to the backlight panel (2). The backlight system (1) further comprises an outcoupling plate (5) arranged adjacent to the backlight panel (2), and adapted to capture a fraction of the light emitted by the light-sources (3a-d) and to outcouple the fraction of light through at least one outcoupling-surface (8a-b) of the outcoupling plate (5), and at least one light-guide (9, 10) arranged to receive the outcoupled light and adapted to guide the outcoupled light towards at least one outcoupling-surface (14a-b, 15a-b) of the light-guide (9, 10). Additionally, at least one sensor (16-19) is arranged to receive the guided outcoupled light and adapted to provide a signal indicative of at least one property of the outcoupled light, thereby enabling adaptive control of the backlight system (1).

摘要： A multi-view display is switchable between single view and multi-view modes, and uses lenticular arrangement over a display panel which includes birefringent electro-optic material adjacent to a non-switchable optically transparent layer. The non-switchable optically transparent layer has a refractive index substantially equal to the extra ordinary refractive index of the birefringent electro-optic material. In the single view mode, the birefringent electro-optic material defines a non-switched state, and the polarization of the light from the display panel and incident on the lenticular arrangement is linear and aligned with the optical axis of the birefringent electro-optic material at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.

摘要： 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.

摘要： The invention provides an adjuster for adjusting the direction of a light beam (5). The adjuster (1) has an off-state and an on-state and comprises a stack (10) of layers. The stack (10) comprises a first solid material layer (100) having a first optic axis (111), a second solid material layer (200) having a second optic axis (211), and switchable birefringent material (30). Further, the stack includes a first interface (130) between the first solid material layer (100) and birefringent material (30) and a second interface (230) between the second solid material layer (200) and birefringent material (30). In the off-state, the birefringent material (30) at the first interface (130) is configured to have an optic axis parallel to the first optic axis (111) and the birefringent material (30) at the second interface (230) is configured to have an optic axis parallel to the second optic axis (211). In the on-state, the birefringent material (30) at the first interface (130) is configured to have an optic axis perpendicular to the first optic axis (111), and the birefringent material (30) at the second interface (230) is configured to have an optic axis perpendicular to the second optic axis (211). This device may be used to redirect light beams, for instance for spotlights, display devices or optical sensors.

摘要： 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.

摘要： An optical arrangement having at least a lens mode in which it is a lens arrangement comprising an array (9) of lenticular lenses (11) each of which has a particular lens surface shape such that, when tracing rays through a lenticular lens after they have entered one side of the lenticular lens, there exists at least one ray that hits the lenticular lens surface perpendicularly. This arrangement gives reduced banding and loss of intensity at steep angles when used in an autostereoscopic display.

摘要： A display device (1) comprising an illuminating member (3) having a plurality of individually controllable light-emitting elements (5), a display panel (2) arranged to be illuminated by the illuminating member (3), the display panel comprising a plurality of individually controllable pixels (4a-d), and a display controller (6) adapted to receive image data (ID) indicative of a color image to be displayed by the display device (1). The display controller (6) is further adapted to individually control a color output of each light-emitting element (5) based on the received image data (ID). The performance of a display device having a controllable illuminating member, such as a backlight or a frontlight, can be considerably improved by individually controlling the color output, rather than merely the intensity,of the light-emitting members comprised in the controllable illuminating member.
