摘要： The invention concerns a colour image panel (100) comprising pixels configured to display a colour image, wherein each pixel includes a tunable photonic crystal filter (20) configured to reflect light (L i ) in a wavelength band of a selected colour and to transmit light (L 2 ) in a different wavelength band in response to a stimulus controlling the photonic bandgap of the tunable photonic crystal filter (20). Each pixel further includes a white display unit (10, 30) driven by a controller (200) so as to control saturation and brightness of the colour displayed by the tunable photonic crystal filter (20), wherein the white display unit controls an amount of white light mixed with the colour light reflected from the tunable photonic crystal filter.

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.

摘要： An optical spectrum filtering device, e.g., color filter, having reduced angle dependence is provided that comprises an interference filter assembly comprising a high refractive index dielectric material, such as a Fabry-Perot based resonator structure. The filter assembly is capable of transmitting a portion of an electromagnetic spectrum into the dielectric material to generate a filtered output with a predetermined range of wavelengths that displays minimal angle dependence, when viewed from a range of incidence angles ranging from normal (0) to 90. Methods of making minimal angle dependent optical spectrum filters and reducing angle dependence for such devices are also provided.

摘要： A liquid-crystal display that can inhibit the coloring of an image when a liquid-crystal panel is viewed from an oblique direction is provided. An optical filter 4 is disposed at the forward end of a liquid-crystal panel 11, the optical filter 4 having different transmittances between a light component that travels in an oblique direction and a light component that travels in a direction normal to the multilayer, both of the light components having a predetermined wavelength range. In the case where a wide-color-gamut light source, such as LEDs, is used as a light sources 8 of a backlight unit 12, when the liquid-crystal panel 11 is viewed from an oblique direction, the entire image area tends to be reddish, and the color temperature tends to decrease. In this case, the optical filter 4 is configured such that the intensity of a visible red light component is selectively reduced and such that the intensity of a visible blue light component is increased, thereby inhibiting the reddening of an image area when viewed from an oblique direction.
