Abstract
A light-emitting sign comprising a light source for emitting light, in which the light-emitting sign may be thin (e.g., comparable to a conventional non-light-emitting sign) while creating a desired visual effect using the light emitted by the light source. This may be achieved, for example, by the light source being thin itself and/or by having an external device connected to the light-emitting sign and implementing certain functionalities (e.g., powering and/or controlling the light source).
