    摘要： A method is provided of driving an electronic device comprising an array of device elements, each device element comprising particles which are moved to control a device element state, and each device element comprising a collector electrode, and an output electrode. The method comprises: in a reset phase, applying a first set of control signals to control the device to move the particles to the a reset electrode; and in an addressing phase, applying a second set of control signals to control the device to move the particles from the reset electrode such that a desired number of particles are at the output electrode. The second set of control signals comprises a pulse waveform oscillating between first and second voltages in which the first voltage is for attracting the particles to the reset electrode and the second voltage is for attracting the particles from the reset electrode to the output electrode, and wherein the duty cycle of the pulse waveform determines the proportion of particles transferred to the output electrode in the addressing phase. This control method provides well-controlled packets of particles which are collected in a vortex at the reset electrode before being passed on, in part, towards the output electrode (for example via the gate electrode).

    摘要： A reflective display, comprising a plurality of pixels (10), each having a first electrode, a light-modifying layer (12), and a second electrode (3; 16) arranged to enable formation of an electric field in the light-modifying layer (12) through application of a voltage between the electrodes. The pixel (10) further includes an active portion (16) which is switchable between light-modifying states by means of said electric field, and an inactive portion (17). The inactive portion (17) is arranged for reflecting light so as to direct at least a fraction of incoming light (20) impinging on the inactive portion (17) towards the active portion (16). As a result, a contrast ratio of the reflective display is improved, since light is now directed from the inactive portion towards the active portion and thus contributes to the displayed image as observed by a viewer.

    摘要： The invention relates to a reflective display panel (9), comprising a plurality of pixels (10, 11a b), each having a modulative portion (15, 16a-b) which is controllable between light-modulation states, and a non-modulative portion (17, 18). The reflective display panel (9) comprises a redirection sheet (14) having a plurality of redirecting structures (19, 20) each being configured to redirect ambient light incident thereon towards an adjacent modulative portion (15, 16a-b). Through the invention, the portion of the light which would otherwise have hit the non-modulative portion of the pixel and would not have contributed constructively to the image forming of the display panel is instead directed towards the modulative portion of the pixel and can thereby contribute to the brightness as well as to the contrast of the reflective display panel.

    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.
