The invention is directed to systems, methods and computer program products for increasing the power efficiency of a display. An exemplary system includes a transflective display that is operable in either a transmissive mode or a reflective mode, and an illumination source with one or more distinct peaks in the illumination source's transmission spectrum, wherein light from the illumination source is directed towards the transflective display during the transmissive mode of operation. For the transmissive mode of operation, the transflective display's transmission spectrum is configured to substantially match the illumination source's transmission spectrum such that one or more narrow passbands in the transflective display's transmission spectrum substantially overlap with the one or more distinct peaks in the illumination source's transmission spectrum. For the reflective mode of operation, the transflective display's reflection spectrum is substantially inversely related to the transflective display's transmission spectrum.

High power efficiency lcd

PROBLEM TO BE SOLVED: To provide an OVD (optically variable device) medium due to diffraction grating pattern, which has high antifalsifying effects or in which an image due to a concave-convex pattern is not recognized in ordinary illuminating conditions and can be displayed by incident radiation from a predetermined direction and, at the same time, which has high attractive effects, and a card-like information medium equipped with the OVD medium. SOLUTION: This OVD medium 22 is equipped with a light transmitting concave-convex pattern forming layer (11), the surface of which keeps the image displayed through the interference and/or diffraction of light, and an optical controlling layer (14), which overlies the image observation side of the concave-convex pattern forming layer and has a region having a light transmittance smaller that its light reflectivity or its light absorptance. The card-like information medium is equipped with the OVD medium. COPYRIGHT: (C)2008,JPO&INPIT

The specification and drawings present a new apparatus (30) and method for using a spectrally selective mirror/filter (34) to facilitate high efficiency of back lighting and high reflectivity of ambient light (33) in an electronic display. The spectrally selective mirror/filter (or optical filter) (34) may be placed between an upper display (spatial light amplitude modulator) (31) and a back light unit (36) comprising light sources generating primary colors (35a, 35b, 35c) such as RBG of a display color gamut. This optical filter (34) has a high reflectivity of visible light except for narrow-band transmission windows substantially coinciding with the primary colors (35a, 35b, 35c).

An optical system consisting of a reflective polarizer, a λ/4 retarder, and a functional transparent plate with first facets and second facets which is provided on a display panel assembly improves utilization efficiency of exterior light, so that display luminance of a reflective or a transmissive LCD operating in a reflection mode is improved. In another embodiment, an optical system consisting of a λ/4 retarder, a selective reflection layer, and a functional transparent plate with first facets and second facets may be used.

This light diffusion member contains rare earth compound particles and a matrix resin, and is configured such that: if T ([mu]m) is the thickness of this light diffusion member and C (mass%) is the amount of the rare earth compound particles added into the matrix resin, the product of the thickness T and the addition amount C is from 200 to 3,000 (inclusive); if the thickness T is 2 [mu]m or more but less than 50 [mu]m, the addition amount C is from 10 mass% to 600 mass% (inclusive); and if the thickness T is from 50 [mu]m to 3,000 [mu]m (inclusive), the addition amount C is from 0.1 mass% to 60 mass% (inclusive). The present invention also provides a light diffusion structure which is obtained by arranging this light diffusion member on a base material. In addition, the present invention also provides a light emitting structure which is provided with this light diffusion member and a light emitting device.
