    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： The invention relates to an electrophoretic color display panel, the display panel comprising at least one pixel (10, 12), the at least one pixel (10, 12) comprising a layer cavity (18ab) containing a suspension with a first set of charged particles (24a) having a first optical property and a second set of charged particles (24b) having a second optical property, and a pair of control electrodes (20a, 20b) arranged adjacent to the layer cavity (18ab), such that charged particles (24a, 24b) are essentially in-plane displaceable in an in-plane direction within the layer cavity (18ab) upon application of a control voltage over the electrode pair, wherein the in-plane distribution of charged particles (24a, 24b) having first and second optical properties in the layer cavity (18ab) depends on at least one of a differing control property additional to any polarity difference of the charged particles (24a, 24b) for each set of charged particles, or at least one additional electrode arranged adjacent to the layer cavity, wherein the electrode pair (20a, 20b) and the at least one additional control electrode are arranged essentially outside of a viewing area (26) of the at least one pixel (10, 12), such that a composite optical property of at least a portion of the at least one pixel (10, 12) is controllable. According to the invention, the control electrodes will be arranged at essentially the outer ends, or arranged in-plane, at a peripheral, of a prolonged layer cavity, such that the particles move in an in-plane direction within the layer cavity when the control voltage is applied. This facilitates the handling of the pixel since the layer cavity can be reached from essentially the outside of the pixel. Another advantage is that since only a minor part of the pixel area has to be covered with an electrode material the total transmission and thus the brightness of the pixel can be optimized.

    摘要： The present invention relates to a drive method for an electrophoretic cell and a device adapted to implement the method. The cell comprises a first storage electrode (24), a second storage electrode (22), a first target area electrode (28), a second target area electrode (30), a first type of particle (32) and a second type of particles (33), said second type of particles being of opposite polarity to the first type of particles. An area (31) extending between the target area electrodes (28, 30) is a target area. The method comprises a reset phase (110), wherein said first and second type of particle are reset to determined reset positions, a first write phase (120), wherein the first type of particles are moved to and/or from the storage electrodes and change in amount in said target area (31), a second write phase (140) similar to the first write phase but for the second type of particles, and a spread phase (150) so that the particles in said target area (31) distribute and mix. The method allows for short distance movements and two particle type in the same cell can be written comparatively fast.

    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.
