An article has optical structures disposed on a base material element. The optical structures include lenticular lens structures and discrete coloring elements having distinct color regions. The lenticular lens structure has several lens layers. The lenticular lens structure may have any of a variety of cross-sectional shapes. The article has a different appearance when an observer views the article at various angles. The appearance may differ in terms of coloring scheme.

An optical fiber draw system that prints one or more fiber identifiers on optical fibers is described. In one example, the optical fiber draw system includes a draw furnace, a coating device, a marking device, and a lighting device. The draw furnace generates a glass fiber from a glass preform and the coating device is configured to apply a curable coating composition to the glass fiber. The lighting device applies an ultraviolet or other curing light to form a coating from the curable coating composition. The application and curing of a curable coating composition can be completed one or more times to form one or more coatings on the glass fiber. The marking device applies a tracer marking fluid to a curable coating composition or coating and can be placed at one or more positions along the process pathway.

The invention provides a shell frame and a manufacturing method thereof. The shell frame includes: a substrate; at least one ink layer coated on the substrate and each being mixed with particles containing a color dye; and at least one cured layer, each of the at least one ink layer being coated with one cured layer, the outmost cured layer having concave and convex shapes to thereby exhibit different colors and patterns at different viewing angles. When the shell frame is pressed, the color dye in the particles is released to make the shell frame exhibit different patterns according to different pressed situations. By the above solution, the invention is capable of making the shell frame transform the pattern along with different angles and thereby achieving visual impact and tactile effect.

A glass display cover with realistic haptic texture and a manufacturing method thereof are disclosed. The glass display cover is for being installed at one side of a display module. The glass display cover includes a glass substrate, a pattern layer, a pattern-highlighting layer, and a textured layer. The glass substrate is installed at the side of the display module. The pattern layer is formed by color layers stacked on the glass substrate. The pattern-highlighting layer is on a side of the pattern layer facing away from the glass substrate. The pattern-highlighting layer is made of a mixture of a white ink and a diluent. The textured layer is formed at a revere side of the glass substrate. The textured layer is made of a solvent material mixed with particles. The manufacturing method includes forming the layers. The textured layer endows the glass display cover with added qualitative value.

A dyeing base body to be used in a dyeing step of dyeing a resin body by heating a sublimable dye attached to the dyeing base body by electromagnetic waves to sublime the dye toward the resin body. The dyeing base body includes a metal base made in sheet form and an electromagnetic wave absorption layer formed on at least an opposite side to the side to which the dye will be attached. The electromagnetic wave absorption layer has a higher electromagnetic wave absorption rate than the base.

The present invention relates to a method for forming a surface relief microstructure, especially an optically variable image (an optically variable device) on a transparent or translucent substrate and a product obtainable using the method. A further aspect of the invention is the use for the prevention of counterfeit or reproduction of a document of value and a method of forming a coating showing an angle dependent color change.

The present disclosure provides a high-refractive index acrylic formulation embedded with sub-30 nm metal oxide nanocrystals. The formulation is solvent-free, low-viscosity, injectable (among other film deposition techniques) and produces high-refractive index, high transparency nanocomposites for a variety of optical applications including OLED lighting and display applications.

A glass sheet includes a symbol marked in the interior of the glass, the symbol forming a code. The symbol is marked in at least two dimensions including the dimension of the thickness of the glass sheet, portions of the symbol being marked at various depths in the thickness of the glass sheet.

Optical waveguides are formed based on measured parameters of an optical substrate. Regions for forming one or more optical elements are identified based on these measurements, and inkjet deposition is utilized to deposit a refraction-matched deposition material is applied to one or more identified regions to selectively modify the total thickness variation (TTV) in each such region. Prior to or subsequent to the deposition, optical gratings or other optical elements are formed within the adjusted regions.
