    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: In an active matrix display device, such as AMLCD, having an array of pixels (P) addressed via sets of row and column conductors (14, 15) to which, respectively, selection and data signals are applied, each pixel comprises a plurality of sub pixels (P1-P4) which each have an associated switch, for example a TFT, (T1-T4) and which are addressed with data signals through a common switch (T1) coupled to a column conductor (15). Addressing the sub pixels through a common switch reduces the effective capacitance of the column conductor. By appropriate control of the switches (T1-T4) the pixels can be driven in a first mode in which the common switch (T1) is operated to control the simultaneous addressing of the sub pixels (P1-P4) with a data signal, for example, for a video display with full grey scale capability, and in a second mode in which the switches (T1-T4) are controlled sequentially to allow different data signals to be applied to the individual sub pixels, for example, as required for a low power standby mode of operation with limited grey scale and colour capability.
