  • Patent number: 11275265
    Abstract: Color conversion films for a LCD (liquid crystal display) having RGB (red, green, blue) color filters, as well as such displays, formulations, precursors and methods are provided, which improve display performances with respect to color gamut, energy efficiency, materials and costs. The color conversion films absorb backlight illumination and convert the energy to green and/or red emission at high efficiency, specified wavelength ranges and narrow emission peaks. Film integration and display configurations further enhance the display performance with color conversion films utilizing various color conversion elements and possibly patterned and/or integrated with a crosstalk blocking matrix. For example, color conversion and/or assistant dyes may be used to enhance spectral regions transmitted through the color filters and shape the illumination spectrum, to improve efficiency and performance.

  • Publication number: 20210212272
    Abstract: Color conversion units and inks for horticultural applications as well as corresponding growing facilities and methods are provided. Color conversion units comprise structural element(s) positioned between natural and/or artificial illumination source(s) and horticultural crop(s), and fluorescent dye(s) embedded in and/or painted on the structural element(s) and configured to convert radiation within absorption range(s) in the specified spectrum into emitted radiation within emission range(s) that are at longer wavelengths than the absorption range(s) and are more readily used by the crop plants and/or modify their growing conditions. Illumination control may be achieved by controlling the types and spatial spread of the dyes, to modify the illumination spectra controllably. For example, dyes may be used to convert ultraviolet, blue and/or green radiation into red radiation which is used better by the plants and/or into growth signals, e.g.

  • Publication number: 20210191198
    Abstract: LCDs (liquid crystal displays) with improved efficiency and performance, as well as corresponding methods are disclosed. Color conversion films and elements with rhodamine-based fluorescent compounds and/or assistant dyes are used to modify the spectrum of the illumination provided by the backlight unit in either or both the backlight unit itself and the LCD panel, in various configurations. Color conversion may be performed above the LC module, possibly by a patterned layer incorporating the color filters, and/or within the backlight unit within a fluorescence-intensifying section in which radiation is recycled to enhance color conversion. Film configuration, positions and optionally supportive structures are provided, to extend the lifetime of the fluorescent compounds. Collimation of backlight illumination may further enhance the optical performance of disclosed LCDs.
