    摘要： A display panel and a display device are provided by the present application. The display panel includes: a glass substrate, wherein the glass substrate is a substrate at the light exiting side of the display panel; and a tandem layer located at the light exiting side of the glass substrate. The tandem layer includes one or more first sub-layers and one or more second sub-layers, and the first sub-layers and the second sub-layers are arranged alternately. A refractive index of each of the first sub-layers and a refractive index of each of the second sub-layers are unequal. A thickness of each of the first sub-layers is less than a thickness of each of the second sub-layers. A visible-light reflectivity of the display panel is less than or equal to 1.1%. The display panel is used to manufacture low-reflectivity display products.

    摘要： A cholesteric liquid crystal display comprising red, green, and blue cholesteric liquid crystal modules. It further comprises a first thin-film photovoltaic module disposed between the blue and the green cholesteric liquid crystal modules, and a second thin-film photovoltaic module disposed between the green and the first selective light reflection modules. The first thin-film photovoltaic module is partially photo-permeable in which the transmittance of blue light is lower than the transmittance of the other lights. It IS preferably a dye sensitized solar cell module which specifically responsible for harvesting blue light. The second thin-film photovoltaic module is partially photo-permeable in which the transmittance of green light is lower than the transmittance of the other lights. It is preferably a dye sensitized solar cell module which specifically responsible for harvesting green light.

    摘要： A light guide element, including a plurality of optical microstructures, has a structure disposed surface and an opposite surface opposite to each other. The plurality of optical microstructures are disposed on the structure disposed surface. Each optical microstructure includes a first surface and a second surface. A first end of the first surface is connected to the structure disposed surface, and a first end of the second surface is connected to a second end of the first surface. A second end of the second surface extends in a direction away from the structure disposed surface. A first included angle is sandwiched between the first surface and a reference plane parallel to the structure disposed surface, a second included angle is sandwiched between the second surface and the reference plane, and the first included angle is smaller than the second included angle.

    摘要： A display device including a substrate, a cholesteric liquid crystal layer, and a transparent electrode layer that are sequentially stacked is provided. The cholesteric liquid crystal layer includes cholesteric liquid crystal molecules and a plurality of transparent photoresist structures. Each of the transparent photoresist structures is a closed structure, and the cholesteric liquid crystal molecules are respectively accommodated in a plurality of patterned areas respectively surrounded by the transparent photoresist structures, so as to form a plurality of cholesteric liquid crystal patterns. The transparent electrode layer includes a plurality of sub-electrodes. The cholesteric liquid crystal patterns are respectively driven by the sub-electrodes. An orthogonal projection of each of the transparent photoresist structures on the substrate falls in an orthogonal projection of a corresponding sub-electrode of the sub-electrodes on the substrate.
