    Abstract: A cholesteric liquid crystal polarizing device includes a substrate, an alignment layer, and a cholesteric liquid crystal layer including multiple domains, each of said domains skewed at an angle relative to a plane parallel to said substrate. The device may be used in combination with a liquid crystal cell to fabricate a reflective liquid crystal display (LCD). In various embodiments, the reflective LCD may be a normally white mode or normally black mode device. In another variation, the liquid crystal cell may include a 90null twisted nematic liquid crystal.

    Abstract: A variable index distributed mirror is disclosed used for high resolution reflective displays that are thin and have high resolution, reflectivity and contrast; wide viewing angle; low power consumption; and low voltage operation. The mirror is electrically switchable or variable between substantially transparent and reflective states. The mirror has alternating layers of a first material having a fixed refractive index, and a second material having a variable refractive index. The second material may be a nematic liquid crystal. The alternating layers are located between a pair of electrodes. The variable refractive index approximately equals the fixed refractive index in the transparent state and differs from the fixed refractive index in the reflective state. The variable refractive index varies in response to a signal applied across the electrodes. The mirror is tuned to a particular color to form a monochrome display. Three such mirrors, each individually driven and tuned to different colors, form a color display. For a black and white monochrome display, the three mirrors are driven collectively.

    Abstract: An optoelectronic device includes an optical waveguide disposed on a substrate. A pair of Bragg reflectors is formed in the optical waveguide to define a resonant cavity between the Bragg reflectors. A piezoelectric material is disposed on the substrate in proximity to the optical waveguide. Electrodes are configured to apply an electric field to the piezoelectric material so as to tune a wavelength of light emitted from the resonant cavity.

    Abstract: A display device may have a reduced thickness while having enhanced color reproducibility by having an improved structure. The display device may include: a liquid crystal panel; a light source plate which is arranged at the rear of the liquid crystal panel to provide light to the liquid crystal panel, and which includes a printed circuit board and an LED chip mounted on the printed circuit board; and a chip cover which is provided to cover a light-emitting surface of the LED chip, and which changes the wavelength of the light emitted from the LED chip, wherein the chip cover includes: a cover layer having a first surface arranged to face the light-emitting surface of the LED chip, a second surface opposite to the first surface, and an accommodating groove provided on the second surface; a light conversion member which changes the wavelength of the light emitted from the LED chip, and which is accommodated in the accommodating groove; and a barrier layer for covering the second surface to cover the light conversion member from the outside.

    Abstract: Electrochromic devices with reflective structure and related manufacturing methods are provided. One of the electrochromic devices includes a bottom electrode layer, an electrochromic layer on the bottom electrode layer, an electrolyte layer on the electrochromic layer, a charge storage layer on the electrolyte layer, and a top electrode on the charge storage layer. The transmittance of the electrochromic device changes in response to a voltage applied between the bottom electrode layer and the top electrode layer. One of the bottom and the top electrode layers is a reflective conductive layer, while the other being a transparent conductive layer. This electrochromic device has a simplified structure due to the removal of a separated reflective film, which also results in simplified manufacturing process.
