    摘要： A display unit of the present invention includes a display section (10) that outputs a first linearly-polarized light as image light, and a display switching section (20) that performs switching between an image display mode and an external light reflection mode. The display section (10) includes a first absorption-type polarization member (11) that allows the first linearly-polarized light to pass through and absorbs second linearly-polarized light. The display switching section (20) includes a reflection-type polarization member (21), a switchable transmission polarization axis member (22), and a second absorption-type polarization member (23). The reflection-type polarization member (21) allows the first linearly-polarized light to pass through and reflects the second linearly-polarized light. The switchable transmission polarization axis member (22) performs switching between a first mode in which the first linearly-polarized light is converted into the second linearly-polarized light and a second mode in which the first linearly-polarized light is not converted into the second linearly-polarized light. The second absorption-type polarization member (23) allows the first linearly-polarized light to pass through and absorbs the second linearly-polarized light. The second absorption-type polarization member (23) has a hue b* value that is equal to or smaller than a hue b* value of the first absorption-type polarization member (11).

    摘要： Projection systems and components thereof are described that are well suited to miniaturization. These systems and components may use one or more of the following features: a folded optical path, as in a reflective cavity or a beamsplitter; an illumination beam that is converging at the place where it impinges upon the spatial light modulator; a beamsplitter that uses opposed prisms of substantially different sizes; a beamsplitter whose obliquely disposed partial reflector defines a first rectangular reference space, and where at least a portion of the light source or at least a portion of the projector lens is disposed within such first rectangular reference space; a system in which a ratio of areas of the first rectangular reference space and a second rectangular reference space is within a specified range, where the second rectangular reference space is just large enough to encompass the optical components of the projector; a system in which the projector lens is small compared to the spatial light modulator.

    摘要： The invention relates to a projection system for a display, in particular a heads-up display, comprising a liquid-crystal screen (12) and a back-lighting device (14) for said screen (12). The projection system is characterised in that said back-lighting device (14) comprises at least one light source (16) emitting light towards the screen (12), at least one lens (38a, 38b) suitable for collimating the light from the light source (16) towards the liquid-crystal screen (12), and reflective means (26) arranged on the surface of the lens (38a, 38b) located on the side of the light source (16), arranged such as to allow light to pass through same towards the screen (12) and to reflect towards the screen (12) almost all of the light propagating towards the lens (38a, 38b).

    摘要： A reflective film includes interior layers arranged to selectively reflect light by constructive or destructive interference, the layers extending from a first zone to a second zone of the film. The film has a first thickness and the interior layers provide a first reflective characteristic in the first zone; the film has a second thickness and the interior layers provide a second reflective characteristic in the second zone. The difference between the first and second reflective characteristics is not substantially attributable to any difference between the first and second thicknesses, which difference may be zero. Rather, the difference in the reflective characteristics is substantially attributable to reduced birefringence of at least some of the interior layers in one zone relative to the other zone. The film may also incorporate absorbing agents to assist in the manufacture or processing of the film. Related methods and articles are also disclosed.
