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.
