Title
(EN) IMAGE TRANSFER METHOD FOR ONE-WAY VISION DISPLAY PANEL
(FR) PROCEDE DE TRANSFERT D'IMAGE POUR TABLEAU D'AFFICHAGE A VISION UNIDIRECTIONNELLE
Abstract
(EN)
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 light-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.
(FR)
Il s'agit d'un procédé destiné à produire une image (18) sur une surface d'un tableau d'affichage à vision unidirectionnelle du type membrane perforée (10) pourvue d'une surface photoréfléchissante opaque (16) et d'une surface photoabsorbante, de sorte que l'image est nettement visible lorsque le tableau est examiné dans un sens, et où ladite membrane permet une vision traversante bien dégagée lorsque le tableau d'affichage est examiné dans le sens opposé. Le procédé comprend les étapes suivantes: report électrostatique de l'encre sur un support de transfert (22) en tant qu'image inversée (18'), puis report de l'image inversée depuis le support de transfert par application de chaleur ou de pression ou les deux afin de former une image voulue, dans une orientation correcte, uniquement sur les parties solides d'une surface de la membrane perforée (10), sans qu'il y ait un transfert de l'image conséquent dans ou à travers les trous (20) de la membrane perforée.
