Abstract
A device for use in organic vapor jet printing (OVJP) and similar arrangements includes a print head movable in more than one degree of freedom with sufficient thermal insulation that there is little to no movement in the Z direction. One or more sensors may be used to monitor and adjust the distance between the substrate and the print head.
