摘要:
A method of displaying an image in an electrophoretic display device includes charging each of the sets of differently colored particles to have a different charge through application of an electric field to the display fluid or the device, and then applying an electric field to selected ones of the multiplicity of reservoirs to effect movement of one or more of the differently colored sets of particles in the display fluid therein to display a desired color derived from among the sets of differently colored particles. The colors are shown by way of the particle set or sets moved to be closet to the viewing side conductive substrate of the device. The device may include at least one display layer, including a multiplicity of individual reservoirs containing a display fluid, between conductive substrates, at least one of which is transparent and thus may be a viewing side substrate, wherein the display fluid includes at least two sets of particles in a liquid medium, the at least two sets of particles exhibiting a different color.

Disclosed is an ink jet printing device including an ink jet print head and a print region surface toward which ink is jetted from the ink jet print head, wherein a height distance between the ink jet print head and the print region surface is adjustable. The ink jet printing device is thus a dual printing device capable of printing both regular height and raised height images such as Braille.
摘要:
A system and a method print one or more images to one or more reimageable documents, wherein the one or more representative of at least a portion of a digital file. The method includes a connecting a portable printer to a computing device. Moreover, the method includes emitting ultraviolet light from a light source, wherein an imaging layer of the reimageable document is imageable by ultraviolet light, wherein ultraviolet light forms a color contrast on the imaging layer that defines an image representative of at least a portion of the digital file.
