An adhesive sign suited to use in retail applications includes a substrate layer. An adhesive layer is disposed on the substrate layer. The adhesive layer defines an exposed region for attachment to an associated structure. The adhesive layer is derived from a photo-curable inkjet composition. An ink layer is disposed on the substrate layer. The ink layer includes an image. The ink layer is derived from a photo-curable inkjet composition. The adhesive layer and ink layer can be formed in the same inkjet printing process and cured in a common photo-curing station. A stack of the adhesive signs can be assembled without interleaving a release liner between each pair of signs.

Described herein are methods for forming e-textiles, wherein the methods include printing a particle-free conductive ink on a textile substrate, and curing the textile substrate to produce a conductive pattern thereon. The printing may include inkjet printing and may produce a printed pattern which exhibits an ink bleed of less than 0.5 mm, such as less than 0.2 mm. During printing, the textile substrate may be heated to a temperature of 30 C. to 90 C. before and during the printing process. The fabric substrate may be cured using heat and/or light to produce a conductive pattern having a sheet resistance of less than 10 /, or even less than 1 /.

A composite includes a plastic substrate and an electrical insulator layer formed on the plastic substrate. The electrical insulator layer contains boron nitride nanotubes (BNNTs), which may be unmodified or modified BNNTS. The composite is suitable for use in making printed electronic devices. A process includes providing a plastic substrate and forming on at least a portion of a surface of the plastic substrate a layer that contains the BNNTs. A metallic ink trace is formed on a portion of the layer, such that the metallic ink trace is spaced-apart from the substrate. Using photonic or thermal sintering techniques, the metallic ink trace is then sintered.

A laser panel, a laser array device, and a laser display. The laser panel and the laser array device separately comprise multiple groups of independent laser light source modules; each group of laser light source modules comprises plural light sources; the plural light sources are all produced by inkjet printing; the laser display and a voltage-driven laser display separately comprise the laser panel. Producing a laser panel by inkjet printing provides a novel technical solution for cheap and industrial manufacturing of laser panels. It is difficult to generate laser coherent superposition between the light emitted by the laser light source module, and therefore, speckles caused by laser coherence in conventional laser display technologies are greatly eliminated. The present invention achieves a voltage-driven laser display, and facilitates achieving a better display effect while reducing the volume of the display.
