ABSTRACT:
In, for example a field emission display, the invention provides the possibility of combining a plurality of sub-substrates that are attached to a larger rear wall, because notably different modes of multiplexing provide a wider positioning tolerance of a sub-substrate with respect to the front plate. Moreover, the different multiplexing techniques lead to a smaller number of connections, even if no use is made of a rear wall supporting of sub-substrates. A plurality of multiplexing techniques provides the possibility of activating a substantially equally large number of pixels of different colours during parts of an image period, so that there is substantially no colour flicker.
