Abstract: To provide a small driver IC, in a pass transistor logic circuit that converts k-bit digital signals into analog signals, transistors supplied with a first-bit signal are arranged in a line in the channel width direction. The channel width of transistors supplied with second to k th-bit signals is made larger than (e.g., preferably larger than two times and smaller than eight times) that of the transistors supplied with the first-bit signal. The transistors are preferably arranged such that transistors of the same conductivity type are located adjacent to each other wherever possible.

Abstract: The present invention concerns generally passive matrix displays, in particular a device comprising a display arrangement (1) and a display driver circuit (2). The display arrangement (1) comprises a liquid crystal material between a first substrate provided with row electrodes (7) and a second substrate provided with column electrodes (6), in which overlapping parts of the row and column electrodes define pixels (8). The display driver circuit (2) comprises means (5) for driving the column electrodes (6) and means (4) for driving the row electrodes (7). The row electrodes (7) supply groups of p rows (p>=2) with row selection voltage levels (V3, VC, MV3) for selecting rows and the column voltage levels (V2, V1, VC, MV1, MV2) are provided by means (5) for driving the column electrodes (6). The column voltage levels (V2, V1, VC, MV1, MV2) to be supplied to the column electrodes (6) are selectable from p+l different column voltage levels (V2, V1, VC, MV1, MV2) depending on the image data to be displayed, wherein the column voltage levels (V2, V1, VC, MV1, MV2) are symmetrically distributed around a middle voltage level (VC). To provide a display device having a low power consumption it is proposed to connect the middle voltage level (VC) in dependency on a deviation from a predetermined value of the middle voltage level (VC) with a higher (Vsupplyl) or a lower voltage potential (VSS) until the predetermined value of the middle voltage level (VC) is reached or the middle voltage level (VC) stays within a tolerance range.

Abstract: Power consumption for driving a liquid crystal display is reduced by connecting together row electrodes that are going through opposite voltage transitions so that the charges would cancel. After such charge cancellation, the respective row electrodes are then driven to respective target potentials by means of drivers. The row and/or column electrodes of the liquid crystal display may also be connected to storage capacitors so that the charges at these electrodes may be stored in the capacitors where the charges stored may be then reused subsequently to drive different electrodes towards target potentials, to reduce power consumption in the subsequent drive of the electrodes to their target potentials. The row voltage driving waveform is such that the driving voltage steps through two or more voltage increments before reaching a final value for turning on or off one or more pixels. This reduces shadows and improves quality of the display.

Abstract: An electrode arrangement for an array of electrically-controllable elements comprises a series of generally parallel electrodes (16) each for extending along a respective line of the electrically-controllable elements, and a series of driver lines (20(1-6)) for receiving driving signals. Each electrode is connected to a plurality of the driver lines each via a respective impedance (26). Each electrode is so connected to at least three of the driver lines. Additionally or alternatively, the driver lines are so connected to the electrodes such that the driver lines cannot be split into a pair of arbitrary groups of the driver lines for which (a) each group has generally the same number of driver lines and (b) each electrode is so connected to at least one of the driver lines in one of the groups and to at least one of the driver lines in the other of the groups. This enables the ratio of the number of electrodes to the number of driver lines to be increased. The impedances in combination with a decoder (24) provide a decoding system which is arranged to perform a plural-stage process in determining which of the driver lines to stimulate in response to each electrode address value supplied to the decoder. This enables the network configuration of the impedances to be machine generated, and also enables the decoder to calculate on the fly which driver lines to stimulate in response to each address value. Furthermore, different resolutions may be provided to enable groups of the electrodes to be addressed simultaneously. The invention is applicable, for example, to liquid crystal displays, arrays of memory elements and arrays of sensors such as light-sensors.

Abstract: A method and apparatus for compensating crosstalk in liquid crystal displays (1 and 2) is disclosed which involves applying boost voltages (V5- and V0+) to the rows (40) and columns (38) of the display (1 and 2) in proportion to the number of ON pixels in a row (40) or column (38), the number of transitions between "ON-and-OFF" or "OFF-and-ON" in each column, and the position of the pixel (Px, y) ina row (40). "Boost" voltages (V5- and V0+) are applied to each row (40) as it is being actively scanned to provide horizontal crosstalk compensation, while "boost" voltages (V5- and V0+) are applied to each column (38) during the vertical retrace interval of the display sequence to provide vertical crosstalk compensation. In a preferred embodiment, the vertical crosstalk compensation is determined during the vertical retrace interval over several frames.
