Abstract: Disclosed is a color liquid display (LCD) employing a transmissive color liquid display panel. The display includes a complementary color light emitting diode, which is one of a cyan light emitting diode (21C), emitting cyan light, a yellow light emitting diode, emitting yellow light, and a magenta light emitting diode, emitting magenta light, in addition to light emitting diodes emitting three prime colors, as a light source. The display also includes a complementary color filter, having at least one of a cyan filter CFC having a transmission wavelength range corresponding to the cyan light, a yellow filter CFY having a transmission wavelength range corresponding to the yellow light and a magenta filter CFM having a transmission wavelength range corresponding to the magenta light, in addition to a tristimulus color filer, as a color filter (19).

Abstract: A dispenser for controlling the release of volatile materials within a contained environment such as an automobile, a home, an office, a factory, or the like, comprises a housing having an opening therein, a volatile material positioned within the housing, and a temperature responsive component in operable association with the opening to regulate said opening in order to contain or release the volatile material. The temperature responsive component automatically controls the release of the volatile material in the contained environment in response to a change in the ambient temperature by uncovering or covering the opening of the housing. A method for controlling the release of volatile materials within a contained environment is also disclosed.
