An electrochromic mirror device suitable for use in a vehicle comprises a first transparent substrate having a transparent conductive layer on a surface thereof and a second substrate having a conductive layer on a surface thereof. The conductive layer of the first substrate opposes the second conductive layer of the second substrate in a spaced-apart relationship thereby forming an interpane distance between the substrates. A boundary seal is interposed between the first and second substrates spacing apart the substrates and forming a cavity wherein the interpane distance is at least about 10 microns. An electrochromic cross-linked polymeric solid film is disposed within the cavity. The electrochromic cross-linked solid polymeric film is formed from an electrochromic monomer composition that includes at least one cathodic electrochromic compound. The second conductive layer comprises a metallic reflective layer.

A method and apparatus is provided for reducing colour shift in relation to viewing angle in an LCD. The method includes receiving a plurality of pixel data constituting an image, each pixel data including a plurality of sub-pixel colour components having respective data values; for each of the pixel data, comparing the sub-pixel colour component data values included therein; and based on the comparison, modifying the sub-pixel colour component data values included in the pixel data to reduce colour shift when displayed on the LCD.

An electrochromic mirror reflective element suitable for use in a rearview mirror assembly of a vehicle includes first and second substrates having an electrochromic medium disposed therebetween and bounded by a perimeter seal. A perimeter coating is disposed at a second surface of the first substrate proximate at least a perimeter portion of the first substrate. The perimeter coating generally conceals the perimeter seal from view by a person viewing a first surface of the first substrate and through the first substrate. An at least partially reflective stack of thin films is disposed at least a portion of a third surface of the second substrate. The perimeter seal is at least partially visible to a person viewing a fourth surface of the second substrate and through the second substrate.

Anthocyanic colorant made of vegetable primary material and process for its production relate to food, cosmetic, pharmaceutical and textile industry and may be used in production of alcoholic and soft drinks, confectionery, products made of sour milk, in coloring of tablet capsules, dying of children's underwear, toys, etc. According to the invention, pelargonidin glycoside was added to the composition of the natural colorant that contained cyanidin glycosides, peonidin glycosides, organic substance and mineral salts. The components percentage shall be as follows, %: cyanidin glycoside 0.1-8.6; peonidin glycoside 0.08-6.45 pelargonidin glycoside 0.005-4.3; organic substance and mineral salts--the rest. Due to the fact that the colorant solution contains pelergonidin glycoside further to cyanidin and peonidin glycosides, the proposed colorant obtained expanded color spectrum. Combination of these three anthocyans in the proposed colorant provides for the most rich spectrum of red colors. At the same time, the ratio of pelargonidin glycoside:peonidine glycoside:cyanidin glycoside must be 1:1.5:2, respectively, and it will provide for production of a colorant with a number of valuable physical properties. Namely, the colorant retains red color when pH of the environment is not more than 7, it is thermostable, photostable and maintains its properties during 2 (two) years, besides, its relative optical density is the highest when it is subjected to the light with wavelength of 505-515 nm. According to the invention, process of the colorant production implies that pre-dried vegetable maize-pulp containing anthocyan is grinded, extracted by a mix of aqueous solutions of hydrochloric and citric acids in the field of ultrasonic vibration. Then the extracted coloring matter is filtered and concentrated in vacuum. The primary material is additionally prepared for extraction by infusion of grinded material in extracting agent during 6-8 hours at the temperature of 35-40.degree. C. Extraction may be performed in three steps. Processing for extraction of each lot shall be 30-40 minutes at the temperature of 35-40.degree. C. The process makes the production technology easier and provides for additional source of primary materials. 2 independent claims, 8 dependent claims, 5 tables.
