Abstract: A display system comprising a backlight device having a light emitting array, a liquid crystal panel, and a color filter having one or more absorbing dyes, wherein the one or more absorbing dyes are located in at least one color set of subpixels in the color filter. The one or more absorbing dyes may be a soluble, blue light, green light, or red light absorbing dye included in blue, green, or red subpixels of the color filter. A blue light absorbing dye may reduce transmission in a wavelength range of 415-435 nm, a green light absorbing dye may reduce transmission in a wavelength range of 490-570 nm, and a red light absorbing dye may reduce transmission of wavelengths less than 620 nm.

The light conversion material is structured and configured to reduce hazardous blue light emissions between about 400 nm to about 500 nm. The disclosed display device can include a liquid crystal panel configured to control transmission of light from the backlight to a viewer. The display device also includes one or more optical films that incorporate one or more light conversion or light absorbing materials. The optical films can be positioned between the layers of the disclosed display device and give enhanced blue-light absorption to the display device.

Abstract: A method of producing an article is described. The method includes (a) providing a substrate comprising an etchable surface layer; (b) coating the etchable surface layer with a composition comprising a non-volatile, etch-resistant component in a volatile liquid carrier; and (c) drying the composition to remove the liquid carrier, whereupon the non-volatile, etch-resistant component self-assembles to form etch-resistant traces on the etchable surface layer. The liquid carrier is in the form of an emulsion comprising a continuous phase and a second phase in the form of domains dispersed in the continuous phase.

Abstract: A composition comprising metal nanoparticles dispersed in a liquid carrier that includes a continuous liquid phase and a dispersed liquid phase, where the composition is in the form of an emulsion. One of the continuous liquid phase or dispersed liquid phase includes at least 40 percent by weight, based upon the total weight of the composition, of an aqueous phase, and the other of the continuous liquid phase or dispersed liquid phase includes an oil phase that evaporates more quickly than the aqueous phase. The metal nanoparticles are present in an amount no greater than 4 percent by weight, based upon the total weight of the composition. When the emulsion is coated onto a surface of a substrate and dried to remove the liquid carrier, the metal nanoparticles self-assemble to form a coating comprising a network-like pattern of electrically conductive traces defining cells that are transparent to light.
