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.

A thermal inkjet dye sublimation ink consists of a disperse dye colorant dispersion, primary and secondary solvents, a chelating agent, oleth-3-phosphate, additive(s), and water. The colorant dispersion is present in an amount ranging from about 1 wt % actives to about 7 wt % actives. The amount of the primary solvent (glycerol, ethoxylated glycerol, 2-methyl-1,3-propanediol, dipropylene glycol, or combinations thereof) ranges from about 10 wt % to about 22 wt %, and the amount of the secondary solvent ranges from 0 wt % to about 7 wt %. The chelating agent amount ranges from 0 wt % actives to less than 0.1 wt % actives, and the oleth-3-phosphate amount ranges from about 0.1 wt % to about 0.75 wt. The additive is selected from the group consisting of a buffer, a biocide, another surfactant, and combinations thereof.
