Abstract: A touch sensor input device comprises a first and second array of electrodes, the electrodes in the first array being orthogonal to the electrodes in the second array. A capacitor sensing arrangement senses an electrode capacitance signal which varies in the presence of a touch input. The capacitance signals for groups of electrodes in each array are combined in order to derive respective individual sense signals. This arrangement has electrodes with a finer resolution than the sensing resolution, and this gives improved ability to sense accurately the position of the touch input.

Abstract: In one example, a current sampling circuit comprises a current sampling transistor, a capacitor arrangement between the gate and source of the current sampling transistor and an amplifier provided in a feedback loop between the gate and source of the current sampling transistor. A switch controls the circuit to sample a gate-source voltage corresponding to a current being sampled onto the capacitor arrangement. The capacitor arrangement comprises a first capacitor circuit for sampling a gate source voltage in a first sampling phase and a second capacitor circuit, with the first and second capacitor circuits arranged for together sampling the gate source voltage in a second sampling phase. The operating point of the amplifier is shifted between the first and second phases based on the gate source voltage sampled in the first sampling phase.
This arrangement provides a coarse sampling phase, which is used to change the operating conditions of an amplifier used within the circuit. This means the amplifier can operate more efficiently in a subsequent fine tuning sampling phase.

Abstract: A position sensing display integrates a touch sensor with an active matrix LCD panel. The panel includes both coarse (12) and fine (4,6) sensing means. The fine sensing means includes fine sense electrodes combined together in groups, the groups being interdigitated i.e. alternating across the display. In use, the fine sensing electrodes determine the position of a sensed object such as a stylus or finger accurately but non-uniquely, and the coarse sensing means determines which of the plurality of non-unique positions is correct.

Abstract: Active matrix display devices capable of improving aperture ratio of pixels and of smoothing intermediate colors are presented. An active matrix display device (1) has static random access memory (SRAM) devices and digital to analog converters (DAC), which are both allocated to each of sub-pixels (3) of a divided pixel. The SRAM stores an input digital data with over two bits, which can be used as gray level information for gray scale display by the respective sub-pixels. The input digital data is converted into analog data for display by the DAC. Gray scale display by the sub-pixels (3) can be performed based on gray scales determined by the analog data for display. The pixel can be used to display multiple gray scales according to combinations of areas and gray scales of the sub-pixels (3) in which one sub-pixel displays MSB gray scale data and a second sub-pixel displays LSB gray scales.

Abstract: A method for controlling printing actions of a print head (1) comprising pumps (10) filled with ink (18), and actuators (16) for generating actuation pulses acting on the ink (18), comprises the step of determining a characteristic frequency of the pumps (10). As the characteristic frequency of the pumps (10) is directly related to the geometry of the pumps (10), the characteristic frequency can be used as an indicator of the state of the pumps (10) and the volume of the ink droplets emitted by the pumps (10). In case a slight change of the characteristic frequency is detected, the actuation pulse is adjusted in order to still meet the requirements regarding the volume of the ink droplets. In case a relatively large change of the characteristic frequency is detected, the printing action of the pump (10) concerned is stopped, and may be taken over by another pump (10).
