    摘要: The invention relates to a microelectronic sensor device and a method for the investigation of biological target substances (20), for example oligonucleotides like DNA fragments. In one embodiment, the device comprises a reaction surface (RS) to which target specific reactants (10) are attached and which lies between a sample chamber (SC) and an array of selectively controllable heating elements (HE). The temperature profile in the sample chamber (SC) can be controlled as desired to provide for example conditions for a PCR and/or for a controlled melting of hybridizations. The reactant (10) and/or the target substance (20) comprises a label (12) with an observable property, like fluorescence, that changes if the target substance (20) is bound to the reactant (10), said property being detected by an array of sensor elements, for example photosensors (SE). The fluorescence of the label (12) may preferably be transferred by FRET to a different fluorescent label (22) or quenched if the target substance (20) is bound.

    摘要: A driving circuit for driving an in-plane moving particle device has a pixel (P) comprising movable charged particles (PA). The pixel (P) has a reservoir electrode (RE), a display electrode (DE), and a gate electrode (GE) laterally placed in-between the reservoir electrode (RE) and the display electrode (DE). The driving circuit (DC) comprises a driver (DR), a controller (CO) which receives an input signal (OS) representing an image to be displayed on the moving particle device. The controller (CO) controls the driver (DR) to supply a first voltage difference (VD1) between the reservoir electrode (RE) and the gate electrode (GE) and a second voltage difference (VD2) between the gate electrode (GE) and the display electrode (DE). The image is written to the pixel (P) during a write phase (TW) by moving particles (PA) from the reservoir electrode (RE) via the gate electrode (GE) to the display electrode (DE) if the optical state of the pixel (P) should change in conformity with the image. If during the write phase (TW) the optical state of the pixel (P) should not change, the first voltage difference (VD1) has a first write level and the second voltage difference (VD2) has a second write level, both write levels are selected to repulse the particles (PA) from the gate electrode (GE). During a repulsion period (TR), the first voltage difference (VD1) has a level more repulsive to the particles than the first write level, and/or the second voltage difference (VD2) has a level more repulsive than the second write level.

    摘要: An in-plane driven moving particle device comprises a first substrate (SUI) and an moving particle material (EM) comprising charged particles (PA), a first electrode (RE) and a second electrode (GE; DE), both arranged on the first substrate (SUI) for generating a predominantly in-plane electrical field in the moving particle material (EM), and a driver (DR). The driver (DR) supplies, during a transition phase wherein an optical state of the moving particle material (EM) has to change, a first voltage (VR) to the first electrode (RE), and a second voltage (VG; VD1) to the second electrode (GE; DE). Both the first voltage (VR) and the second voltage (VG; VD1) comprise a sequence of a plurality of predetermined levels having predetermined durations, and wherein the first voltage (VR) and/or the second voltage (VG; VD1) have a non-zero average level. The levels, durations and average level are selected for allowing the particles (PA) to move between the first electrode (RE) and second electrode (GE; DE) in opposite directions to change the optical state a plurality of times in opposite directions during the sequence, and to obtain a net movement of the particles during the transition phase in a direction of an electrical field caused by the average level.

    摘要: A display device and a method for driving the display device is disclosed. The display device comprises drive circuitry (35) and a plurality of pixels (PIX1, PIX2, PIX3, PIX4, PIX5, PIX6) having movable charged particles (116). The drive circuitry is configured to apply control signals to the pixels to move the charged particles between first (110) and second (112) regions of each pixel in order to alter the optical appearance of each pixel. The method for each pixel comprises a pre-addressing stage (PRA) of moving the charged particles towards the boundary (114) between the first and second regions, and then an addressing stage (ADD) of moving the particles to one side or the other side of the boundary, in dependence on the desired optical appearance of the pixel.
