Abstract: A method is provided of controlling an illumination source for a display device which comprises a display modulator (28) for modulating the light provided by the illumination source (42). The method comprises using a light sensor arrangement (30) to generate a first signal (D M1 ) based on an ambient light level with first illumination source drive conditions, and using the light sensor arrangement to generate a second signal (D M2 ) based on the same ambient light level but with second illumination source drive conditions different to the first drive conditions. The first and second detected signals are processed to compensate for differences in the light sensor arrangement response characteristics when operating with the first and second illumination source drive conditions thereby to derive a compensated light sensor arrangement characteristic covering both the first and second illumination source drive conditions. Ambient light levels detected using this model of the characteristic are used to control the display device.

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: The memory comprises at least two data storage units using hot carrier stressing damage to store data. Each data storage unit comprises the first terminal, the second terminal and a third terminal. When the first cross voltage between the second and third terminals is higher than the first threshold voltage and the second cross voltage between the first and third terminals is higher than the second threshold voltage, the data storage unit is in the first writing operation.

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.

Ambient light levels detected using this model of the characteristic are used to control the display device.
