Abstract
A light source comprises an array of contiguous transparent blocks, each of which contains a light emitter such as a cold cathode fluorescent tube. The blocks have a transparent front surface which may be optically diffusing, the other surfaces being coated with a thin optically reflective layer so that each block acts as a light guide. The tubes are independently controllable, for instance so as to simulate a moving light source which may be controlled so as to track the position of an observer of a 3D display.
