<p>A demultiplexer applies picture information to pixels arranged in an array of a display device having columns and rows. The demultiplexer includes transistor switches each having a control terminal, an input terminal and an output terminal. A first bus couples switch control signals to the control terminals of the switches. The conductors of a first bus extend in a region containing each of the switches to form a global bus arrangement. Local buses have each conductors coupled to the input terminals of the switches associated with the individual local bus. The output terminals of the switches associated with the individual local bus are coupled to corresponding, consecutively disposed column conductors of the array. The individual local bus has a section that crosses over the first bus and a second section extending between the crossover section and the input terminals of the associated switches. The conductors of the second section extend in a region containing the associated switches and are absent from regions containing switches associated with the other local buses to obtain bus separation forming a local clustering bus arrangement.</p> |
