    摘要: An active matrix array device has a plurality of matrix array elements (100), each of which have a first capacitive device (120) coupled to a charging conductor (32m) via a first switch (100) being responsive to an addressing conductor (22n). In addition, the matrix array elements (100) comprise a second capacitive device (130) coupled to the first capacitive device (120) via a second switch (112) being responsive to en enable signal provided via an enable conductor (42n). The second capacitive device (130) is coupled to the control terminal of a third switch (114), which is coupled between the first capacitive device (120) and a potential source like the charging conductor (32m). The second capacitive device (130) is used to sample the voltage across the first capacitive device (120), which enables the third switch (114) if of an appropriate value, thus providing a conductive path between the first capacitive device (120) and the potential source. This arrangement allows for a low-power data refresh mode of the matrix array elements (100) with polarity inversion in subsequent refresh cycles.

    摘要: An amplification circuit comprises a capacitor arrangement (42) and a switching arrangement The capacitor arrangement has a first capacitor (C2) which has a voltage-dependent capacitance and a second capacitor (C1) (which may also be voltage-dependent). The circuit is operable in two modes, a first mode in which the input voltage is provided to one terminal of at least the first capacitor, and a second mode in which the switching arrangement causes charge to be redistributed between the first and second capacitors such that the voltage across the first capacitor changes to reduce the capacitance of the first capacitor, the output voltage being dependent on the resulting voltage across the first capacitor. The invention uses a voltage controlled capacitance in combination with charge sharing between capacitors, which has the result of providing a voltage amplification characteristic. This arrangement can thus be used for the amplification of an analogue voltage, or the boosting of a fixed level (i.e. digital voltage). Thus, the circuit of the invention can be used for level shifting or amplification, for example for use in the pixels of an active matrix array device.

    摘要: An active matrix array device has driver circuitry for providing address signals to the matrix elements and which includes digital to analogue converter circuitry. The driver circuitry is arranged alongside one edge of the array of matrix elements, and comprises a multiple voltage level generator circuit providing a plurality of analogue voltage levels for addressing the matrix elements, with the plurality of levels being provided on outputs distributed substantially along the length of the one edge. A group of switches is associated with, and located at, each output of the voltage level generator circuit and provides signals to an output bus arranged alongside the one edge and having the first number of lines.

    摘要: An active matrix display has a column driver for providing signals to the pixels for driving the display elements, the column driver comprising digital to analogue converter circuitry providing a first number of display element drive levels. Within each pixel, the first number of display element drive levels is converted into a second, greater number, of pixel grey levels. This combines multi-level digital to analogue conversion with in-pixel level generation and enables the complexity of the DACs to be reduced so that they can be integrated onto the display substrate, for example using low temperature polysilicon processing.

    摘要: An array device has switching circuits in each pixel for selectively routing one of at least two inputs to a pixel element. Switching transistors are connected between a respective one of the at least two inputs and the pixel element. The timing of the operation of the switching transistors is determined in dependence on the data waveform of at least one of the inputs, and a capacitive connection is provided between the gate of at least one of the switching transistors and an output of the switching transistor. This enables a reduction in the data voltage range which is required to ensure that the switching transistors switch correctly, by using a bootstrapping technique. In particular, by controlling the timing of application of the data signals for switching on or off the switching transistors, the voltage levels of at least one of the input signals can be used to provide capacitive coupling through the respective switching transistor onto the bootstrapping capacitor.
