Abstract: A liquid crystal display device including a first substrate arranged on a front side, i.e., arranged on the side receiving an incident light, and a second substrate arranged on a back side, so that this second substrate extends facing the front substrate parallel thereto, the first and second substrates being connected via a sealing frame in order to delimit between them a cavity for containing the liquid crystals and including on their opposite faces a first and a second group of electrodes, respectively. The display device is connected to a control circuit for supplying suitable control voltages to selected electrodes in order to modify the optical conditions of the liquid crystal into a reflective state or into a transparent state. The display device further includes an absorbent black layer made of an electrically non-conductive material, wherein the absorbent black layer is arranged either at the surface of the second substrate or on the second group of electrodes that is formed on the second substrate.

Abstract: A display having polymer dispersed liquid crystals, which display comprises a transparent substrate; a layer comprising polymer-dispersed cholesteric liquid crystal disposed over the substrate, which layer has more than one stable optical state in the absence of an electrical field. The display further comprises a first transparent conductor disposed between the state changing layer and the transparent support, a second conductor on the other side of the state changing layer so that when a field is applied between the first and second conductors, the liquid crystals change state. It has been found advantageous to have a non-conductive, non-field spreading dark layer of sub-micron pigments in a binder for providing an improved light absorbing function, which dark layer is disposed between the layer of polymer-dispersed cholesteric liquid crystal and the second conductor.

Abstract: A window assembly includes an electro-optic element which has a first substantially transparent substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A second substantially transparent substrate defines third and fourth surfaces. The third surface includes a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed in the cavity. The electro-optic medium is switchable such that the electro-optic element is operable between substantially clear and darkened states. An absorptive layer is positioned on the fourth surface of the electro-optic element and a reflective layer is positioned on the absorptive layer.

Abstract: A transmissive optical device comprising: a layer (10) of light absorber material in the solid state, preferably made of a phase-change material with switchable refractive index such as GeSbTe; a partially-reflective layer (12), and a spacer layer (14) between the layer (10) of light absorber material and the partially-reflective layer (12). The spacer layer (14) and an optional cover layer (16) may be transparent conductive ITO layers which may serve to electrically switch the phase of the phase-change material layer (10), thereby switching the transmission/reflection properties of the transmissive optical device.

Abstract: A low reflectance film with a second reflectance (50% or lower) lower than a first reflectance is formed between an optical directional coupler and a first-layer wiring with the first reflectance. Thus, even when the first-layer wiring is formed above the optical directional coupler, the influence of the light reflected by the first-layer wiring on the optical signal propagating through the first optical waveguide and the second optical waveguide of the optical directional coupler can be reduced. Accordingly, the first-layer wiring can be arranged above the optical directional coupler, and the restriction on the layout of the first-layer wiring is relaxed.

Abstract: The invention discloses a QD CF substrate and manufacturing method thereof. The manufacturing method uses a patterned photo-resist layer as a masking layer to perform selective quenching on QD layer with a quencher to obtain selectively quenched QD layer, which simplifies QD CF substrate manufacturing process and reduces cost. The QD CF substrate does not use blue QD material in QD layer, but uses blue backlight and organic transparent photo-resist layer to improve light utilization efficiency and reduce material cost. The QD layer is a selectively quenched QD layer, and the portion of the QD layer located above the organic transparent photo-resist layer is quenched by the quencher, and will not emit light when excited by backlight. As such, the invention achieves using the QD material to improve color gamut and brightness, avoid color impurity at blue sub-pixels caused by light mixture, and the manufacturing method is simple.
