IMAGE TRANSFER METHOD FOR ONE-WAY VISION DISPLAY PANEL

摘要

A method of producing an image (18) onto a surface of a one-way vision display panel of the type which is constructed as a perforated membrane (10) having an opaque tight-reflective surface (16) and a light-absorbing surface and whereby the image is clearly visible when viewing the display panel from one direction and wherein the perforated membrane permits substantially unobstructed through-viewing when viewing the display panel from a second, opposite direction. The method includes the steps of: electrostatically transferring ink onto a transfer medium (22) as a reverse image (18'); and transferring the reverse image from the transfer medium using heat and/or pressure in order to form a desired correctly oriented image onto only the solid bar portions of a surface of a perforated membrane (10) without any substantial image transfer into or through the through-holes (20) of the perforated membrane.
