The invention relates to a method for manufacturing an optoelectronic component substrate (12) comprising a stack of layers, the method comprising a step of: preforming a substrate (12) comprising a face which has a pattern with at least one zone made of a first material and one zone made of a second material, the two materials being thermosetting or thermoplastic materials, the first material being an electrically conductive material and the second material being an electrically insulating material, and molding by compression the face of the substrate (12) with a face of a reference element (22) having a surface roughness less than or equal to 50 nanometers.

Provided is a structure of foam-injection molding including an EL sheet. The structure includes: a base material; an electro luminescence(EL) sheet which is able to emit a light, and which is disposed on an upper side of the base material; a foam layer disposed on an upper side of the EL sheet; and a skin layer disposed on an upper side of the foam layer.

A liquid crystal display device, includes a display panel; a light guide plate to transfer light to the display panel; and a light source module on a side surface of the light guide plate to supply light to the light guide plate, the light source module including a light source to generate light; and a quantum dot unit between the light source and the light guide plate, the quantum dot unit extending along the side surface of the light guide plate and including a tube member filled with a resin including quantum dots, the tube member including a sealing part.

A template made of plywood or similar material is inserted into a cover for a protective helmet so that the cover is stretched and once the template is inserted the assembled combination of the cover and the template resembles the shape of a disk. The disk-shaped assembly is placed on top of the bottom plate of a heat press. A layer with a decal or sticker is placed on top of the disk-shaped assembly. A heat press cover sheet is then placed on top of the disk-shaped assembly so that it also becomes into contact with the top plate of the heat press when the heat press is closed. The heat press may be set to a temperature of 350 degrees Fahrenheit and it can be set in a closed position for about 30 seconds in order to transfer sufficient heat so that the decal or sticker is applied or affixed to the cover surface.

An LED is fabricated with a composite layer including quantum dots (QDs), wherein the QDs are provided in a silicone paste. A plurality of QD silicone paste reservoirs each contain a provided silicone paste with QDs of different wavelengths. Further, a silicone paste reservoir containing a clear silicone paste. A paste mixing chamber, in to which the QD paste reservoirs and the silicone paste reservoir supply their respective pastes, mixes together the pastes and form a mixed QD silicone paste. A silicone mixing and metering component receives the mixed QD silicone paste from the paste mixing chamber, and further receives A silicone and B silicone from a respective A silicone reservoir and a B silicone reservoir, measures, and mixes the mixed QD silicone paste with the A and B silicones to form a silicone polymer composite. A dispensing component receives to the silicone polymer composite from the mixing and metering component and dispenses the composite to a molding tool.
