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.

Bus arrangement for a driver of a matrix display

A pixel structure having at least one organic thin film transistor (OTFT) that minimizes gate-to-pixel capacitance. In one embodiment, a pixel structure provides a new transistor structure where an OTFT electrode on the data-line side of the transistor is extended or wrapped around three sides of the transistor relative to a pixel-side electrode. Thus, the pixel-side electrode can be made very small without reducing the effective width (and therefore on-current) of the transistor.

Method and apparatus for providing a high-performance active matrix pixel using organic thin-film transistors

LED pixel structures and methods that improve brightness uniformity by reducing current nonuniformities in a light-emitting diode of the pixel structures are disclosed.
