ASSISTANT DYES FOR COLOR CONVERSION IN LCD DISPLAYS
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.
Preparing unsaturated carbocyclic compounds
Disclosed are methods of preparing unsaturated carbocyclic compounds through dehydrogenation of corresponding saturated carbocyclic compounds.
VETIVER ODORANT
Compounds of formula (I) in the form of any one of its stereoisomers or a mixture thereof are provided, wherein the dotted lines represent a carbon-carbon single bond or a carbon-carbon double bond; and one R.sup.1 group represents a hydrogen atom and the second R.sup.1 group represents a methyl group. Also provided are their uses as perfuming ingredients to impart vetiver/rooty and powdery notes; e.g. in perfuming compositions or in consumer products.
