摘要： In a digital to analogue converter, a plurality of digital inputs are used to select one of first and second binary voltage levels as binary inputs (10) to the converter. A capacitor circuit (C, 2C, ..., 32C) is associated with each input, and these are controlled to output an effective voltage to an output load comprising the first binary voltage level, the second binary voltage level or an average of the first and second binary voltage levels in dependence on the bits of the digital input word. The plurality of capacitor circuits can be operated in either a voltage divider mode (to provide an average output) or a resistor mode depending on the value of the digital data. Operation of the capacitor circuits in this way can result in a reduction in the currents flowing and can therefore reduce the power consumption.

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.

摘要： An active matrix display device, such as an AMLCD, having sets of row and column address conductors (18, 19) connected to a row and column array of picture elements (12) and drive means (21, 23, 25) for supplying selection and data signals to the sets of rows and column address conductors respectively uses a plurality of serial charge redistribution digital to analogue conversion means (30) to convert multi-bit digital data signals supplied to the column address conductors (19) into analogue voltage levels for use by the picture elements. Each conversion means uses the capacitances of two column address conductors between which charge is shared by operation of conversion switches (31). The drive means is arranged to supply data signals alternately to the two column address conductors of each conversion means. This leads to a reduction in conversion errors and consequential unwanted display artefacts. Preferably, the column address conductor to which data signals are applied is changed after one or more complete multi-bit conversions performed by the conversion means. The required change over is accomplished using a simple switch arrangement.

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 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.
