1. A method of sizing a flexible light sheet, wherein (a) the light sheet comprises (i) a flexible substrate having first and second opposed surfaces and (ii) a plurality of light-emitting elements disposed over the first surface of the substrate, and (b) in a first direction along the light sheet, the substrate has an initial size larger than a desired size, the method comprising:
folding, along a line not parallel to the first direction, a first portion of the light sheet beneath a second portion of the light sheet, wherein (a) the second portion of the light sheet has the desired size, (b) a first group of one or more of the light-emitting elements is disposed on the first portion of the light sheet and a second group of one or more of the light-emitting elements is disposed on the second portion of the light sheet, and (c) after the light sheet is folded, (i) light is emitted by both the first and second groups of light-emitting elements, and (ii) light emitted by the folded light sheet and observable to a viewer thereof comprises light emitted by the second group of one or more of the light-emitting elements but not light emitted by the first group of one or more of the light-emitting elements. |
