Abstract:
1. An active matrix display device comprising: an array of pixels, a set of row conductors through which rows of pixels are selected, a set of column conductors through which data signals are supplied to selected pixels, each pixel comprising a plurality of sub pixels in which sub pixels are each associated with a respective switching transistor for controlling the supply of a data signal to the sub pixel, a timing and control unit for controlling a row drive circuit and a column drive circuit that provide driving signals and the data signals to the array of pixels, the timing and control unit selectively switching between a first mode of operation and a second mode of operation in response to a mode selection control signal, wherein the plurality of sub pixels of a pixel are coupled to a column conductor associated with the pixel via a common switching transistor through which data signals are supplied to the sub pixels, and wherein the device is selectively operable in the first mode in which the plurality of sub-pixels of a pixel are addressed simultaneously with a data signal and in the second mode in which the sub pixels of a pixel are addressed individually with respective data signals.
