72 results about "Additive color" patented technology

Additive color, or "additive mixing", is a property of a color model that predicts the appearance of colors made by coincident component lights with distinct colors, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. Modern formulations of Grassmann's laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. It is important to note that additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching experiments where viewers match small patches of uniform color isolated against a grey or black background.

Liquid crystal display device and its production method

The objective of the present invention is to provide a liquid crystal display device for displaying colors by transmission and reflection modes and a method for producing such devices, whereby the additive color mixing can be used, the structure is simplified, the driving-voltage is lower, the contrast is higher, the response speed is higher, and the screen can be larger. This objective can be achieved by a method including the following steps: mixing 0.001 to 20 wt % of dichromatic melanotic pigment into chiral nematic liquid crystal mixed with chiral dopant; preparing a mixture of the liquid crystal and prepolymer to be polymerized into transparent polymeric solid; inserting the mixture into the space between two conductive substrates, wherein at least one of which is transparent; and irradiating ultra-violet light or neighboring short-wavelength light onto the mixture. This process creates an accumulation of small packets composed of the liquid crystal packed with a thin film of the transparent polymeric solid within a light-controlling layer between the two conductive substrates. When no voltage is applied, the pigment molecules absorb light because they are distributed within the space with their longitudinal axis randomly directed. When a voltage is applied, elongated liquid crystal molecules are oriented perpendicular to the substrates, and the pigment molecules are also oriented in a similar manner. In this state, the black color of the pigment molecules does not appear, so that light is allowed to pass therethrough.

Method for mixing colors of solid wood floor paint

The invention relates to a method for mixing colors of solid wood floor paint. The method comprises the following steps: according to six ratios being 1 percent, 2 percent, 3 percent, 4 percent, 5 percent and 6 percent of three color concentrates of red, yellow and black relative to the quality of water-based primer, mixing to prepare an additive color primer sample; coating the black and white paperboard with the additive color primer sample through a coating rod, and thus obtaining a paint film sample; by means of a color measuring and matching system composed of a spectral color measurement instrument and Colibri color matching software, detecting the color data of the paint film sample, and saving the color data in the color matching system; inputting the quality data of the water-based primer used for manufacturing the paint film sample and the three color concentrates of red, yellow and black into the color matching system, computing and processing the quality data with the Colibri color matching software, and thus building a color concentrate database; before the colors of the paint is mixed, detecting the color of a plain floor board as a bottom color and the color of a painted finished product floor as a target color; by means of the color concentrate database, automatically computing the application proportion of the three color concentrates of red, yellow and black of paint films with various thicknesses through the color matching system. The accuracy and efficiency of color mixing of paint are high.

Anti-cracking ultraviolet-cured coating system for solid-wood sheet material

The invention belongs to the field of ultraviolet-cured new materials, and particularly relates to a coating system which is mainly applied to the protection and the decoration of solid-wood sheet materials of a solid-wood floor, a multilayer solid-wood floor, a bamboo-wood floor and other solid-wood floors. The invention provides a coating system which is used for solving the problem that a paint film cracks as a sheet material cracks when the solid-wood sheet material is used in an environment of which the diurnal temperature difference is relatively large. An anti-cracking ultraviolet-cured coating system for a solid-wood sheet material consists of aqueous additive color priming paint, UV (ultraviolet) flexible priming paint, UV hard priming paint and UV surface paint. The UV flexible priming paint forms a paint film which is high in binding force and high in flexibility by means of the coloring and the adhesive force of the aqueous additive color priming paint; then the UV hard priming paint and the UV surface paint are coated, and are cured by ultraviolet light to respectively form films under the action of a light initiator, so as to form a multilayer coating film structure which is high in binding force, good in flexibility and high in interlayer adhesive force, and the characteristics of anti-cracking, high hardness and high scratch resistance are realized.
