A method for producing a trim component capable of providing light for the interior of a vehicle, comprising: providing a formed device having a surface that emits light wherein said formed device has a thickness of 0.5 mm to 3.0 mm, including a backside and edges which are adjacent to each other; and wherein said formed device includes a light transmissive substrate (28a, 28a'), an LED light source (24, 24') as a lighting device deposited on the light transmissive substrate and electronics printed on said light transmissive substrate (28a, 28a'); placing said formed device in a mold for forming said interior trim component; and introducing a flowable plastic adjacent the backside and the edges of said formed device in said mold wherein said the backside and the edges of said formed device are partially embedded in said flowable plastic and wherein said flowable plastic forms attachment structure for said interior trim component in said vehicle, wherein providing said formed device includes providing an inkjet printer; providing a sheet of plastic to said printer, said sheet forming said light transmissive substrate (28a, 28a'); advancing said sheet through said printer whereby droplets of ink are deposited from one or more print heads in said printer onto a surface of said sheet, said droplets deposited in such a pattern so as to create a printed electronic, optical and lighting device; drying said ink droplets; expelling said sheet from said printer, providing a top layer attached to said printed sheet; trimming said combination of top layer and sheet to provide said formed device; directly forming said formed device to a shape wherein said shape complements a surface of said mold for forming said interior trim component; wherein said formed device is placed against said surface in said mold before introducing said flowable plastic behind at least a portion of said formed device in said mold. providing a formed device having a surface that emits light wherein said formed device has a thickness of 0.5 mm to 3.0 mm, including a backside and edges which are adjacent to each other; and wherein said formed device includes a light transmissive substrate (28a, 28a'), an LED light source (24, 24') as a lighting device deposited on the light transmissive substrate and electronics printed on said light transmissive substrate (28a, 28a'); placing said formed device in a mold for forming said interior trim component; and introducing a flowable plastic adjacent the backside and the edges of said formed device in said mold wherein said the backside and the edges of said formed device are partially embedded in said flowable plastic and wherein said flowable plastic forms attachment structure for said interior trim component in said vehicle, wherein providing said formed device includes providing an inkjet printer; providing a sheet of plastic to said printer, said sheet forming said light transmissive substrate (28a, 28a'); advancing said sheet through said printer whereby droplets of ink are deposited from one or more print heads in said printer onto a surface of said sheet, said droplets deposited in such a pattern so as to create a printed electronic, optical and lighting device; drying said ink droplets; expelling said sheet from said printer, providing a top layer attached to said printed sheet; trimming said combination of top layer and sheet to provide said formed device; directly forming said formed device to a shape wherein said shape complements a surface of said mold for forming said interior trim component; wherein said formed device is placed against said surface in said mold before introducing said flowable plastic behind at least a portion of said formed device in said mold.
