A light-emitting display sheet includes a first fiber base material layer and a surface material layer stacked on the first fiber base material layer. The first fiber base material layer includes a first surface facing the surface material layer, and a second surface opposite to the first surface. The light-emitting display sheet further includes a print portion having an outline and sandwiched between the first surface of the first fiber base material layer and the surface material layer.

Moir is an appealing visual effect observable when two or more repetitive patterns are superposed. We introduce a method for designing and fabricating level-line moirs on curved surfaces. These moir shapes are obtained by superposing a partly absorbing or partly light deviating curved base layer and a curved revealing layer formed by a grating of transparent lines or cylindrical lenses. The distances between base layer and revealing layer are adapted to the locally varying distances between successive transparent lines or cylindrical lenses of the curved revealing layer grating. We demonstrate the quality of our method by rendered simulations and by fabrication. The resulting level-line moir display devices can be manufactured using different fabrication techniques, from multi-material 3D printing to molding.

The invention relates to a 2D printing method on a 3D printing support, consisting of forming a printing support comprised of a plurality of colored fibers that follow a printing pattern, which once joined and shaped into a block, can be transversally cut, thereby obtaining printed sheets according to said printing pattern. The invention further relates to the printing support, comprised of a block (1), wherein in one embodiment same is composed of a plurality of hollow tubes (2) having a cavity that can be filled with a coloring means and in another embodiment same is composed of solid tubes. After the coloring means hardens and the block (1) solidifies, the latter can be transversally cut parallel to the printing face (4) into a plurality of strips (5) that will depend on the required volume of advertising signs, posters or banners, among others.

A method of cold forming a glass laminate structure. The method includes assembling a multi-layer structure having two buffer plates and a glass laminate structure intermediate the two buffer plates, wherein one or both of the two buffer plates includes a pattern formed thereon or therein or the multi-layer structure includes non-deformable materials forming a pattern. The method further includes cold forming the glass laminate structure in the autoclave by heating the assembled structure to a temperature about 5 to 10 degrees above the softening point of the polymer interlayer for a predetermined period of time at a predetermined pressure. After processing the glass laminate structure can be removed from between the buffer plates wherein the pattern formed in or on the one or both buffer plates or non-deformable materials has been transferred to the glass laminate structure as a function of variances of thicknesses in the glass laminate structure.
