摘要： The present invention relates to a method of manufacturing a substantially planar substrate (1), formed of at least a first and a second material (3, 4) having substantially different conductivities, such that conductive channels (2) are formed substantially perpendicular to the substrate surfaces, and the conductivity perpendicular to the substrate surfaces, as measured over a predetermined area, is substantially larger than the conductivity parallel to the substrate surfaces. Furthermore, the invention refers to a display device (23) comprising at least one substrate (1) manufactured according to the present method, an optically active layer (8; 24), and at least one control electrode (10), thereby enabling the provision of a local electrical field over the optically active layer (8; 24).

摘要： The invention relates to a method for providing in a foil a number of recesses which are arranged relative to each other in a recess pattern extending along a first side of the foil, each recess extending from a first side in the direction of an opposite, second side of the foil, the method comprising at least the following steps: (a) applying a medium pattern onto the unprocessed foil, the medium comprising a medium solvable in solvent, the medium pattern corresponding to the recess pattern to be provided; (b) applying the masking layer onto the foil; (c) bringing the foil, with the masking layer applied thereto, into contact with a solvent, whereby the parts of the masking layer applied substantially on the medium pattern are removed from the foil upon dissolution of the medium pattern; and (d) at least partly exposing the foil with the pattern of openings to a foil etching environment, whereby the recess pattern is created, characterized in that in step (a) the application of a medium pattern is executed with the aid of a printing technique.

摘要： Substrate (7; 7'; 10) and devices including such a substrate, the substrate having a first surface and a second surface extending substantially in parallel to the first surface, the substrate being of a material of a first conductivity and provided with a plurality of electrically conducting channels (21) which are extending exclusively in a direction perpendicular to the first and second surfaces, said channels having a second conductivity substantially larger than the first conductivity, the substrate being provided with at least one electrode (42) on either one of the first and second surfaces, contacting at least one of said channels, the at least one electrode (42) having a predetermined minimum dimension (D) in a contact area (A) with the substrate, and mutual distances between adjacent ones of the plurality of channels (21) being smaller than said minimum dimension of said at least one electrode (42).
