Method for manufacturing electronic products, related arrangement and product

A manufacturing system for an electronic product or device, the manufacturing system comprising:

• equipment configured to:
• print, by an additive printed electronics process, a plurality of electrical conductors on a flexible, optically substantially transparent or translucent substrate sheet according to a predefined layout,
• provide a plurality of electronic components including optoelectronic light emissive components on the substrate sheet according to the predefined layout, at least some of the printed conductors being configured to provide electrical current thereto, and
• attach a flexible, optically substantially transparent, pre-prepared lightguide sheet with the substrate sheet to establish a functional multi-layer laminate structure in which the light emitted by the light emissive components is received by the lightguide sheet, propagating therewithin, and then being at least partly emitted to the environment through the same substrate sheet on which the light emissive components are provided,
• wherein the light emitted by the light emissive components is contained entirely within the lightguide sheet by total internal reflection until being at least partly emitted to the environment by outcoupling via an outcoupling-affecting element, and
• wherein the outcoupling-affecting element comprises an adhesive.

An electronic system comprising:

• an optically functional multi-layer structure incorporating:
• a flexible, optically substantially transparent or translucent, substrate sheet, provided with a plurality of electrical conductors printed thereon,
• a plurality of electronic components including optoelectronic light emissive components arranged on the substrate sheet, at least some of the printed conductors being configured to provide electrical current thereto, and
• a flexible, optically substantially transparent, pre-prepared lightguide sheet attached to the substrate sheet and configured such that the light emitted by the light emissive components is received by the lightguide sheet, propagating therewithin, and being at least partly emitted to the environment through the same substrate sheet on which the light emissive components are provided;
• and
• additive printed electronics equipment configured to print the electrical conductors on the flexible, optically substantially transparent or translucent, substrate sheet,
• wherein the light emitted by the light emissive components is contained entirely within the lightguide sheet by total internal reflection until being at least partly emitted to the environment by outcoupling via an outcoupling-affecting element, and
• wherein the outcoupling-affecting element comprises an adhesive.
