| Electrophoretic display panel | 20060290650 | 20061228 |
| An electrophoretic display panel and a method for driving an electrophoretic display panel in which the drive pulse, i.e. the grey scale pulse, to bring an element from a preceding optical state to an optical state is split in more than one sub-pulses. A more gradual introduction of the grey scale is thereby achieved reducing the suddenness of the transition form one image to another. Preferably application of the grey scale potential differences is preceded by application of reset pulses in which case the preceding optical state is an extreme optical state.

| Driving scheme for monochrome mode and transition method for monochrome-to-greyscale mode in bi-stable displays | 20060290652 | 20061228 |
| Image quality is improved when updating a display image (310) in a bi-stable electronic reading device (300, 400) such as one using an electrophoretic display, by providing both monochrome and greyscale images. When an update mode of a pixel (2) of the display changes from a monochrome to greyscale, a compensating pulse (805, 825, 845, 865) is applied. The compensating pulse represents an energy based on the energy difference between: (a) an over-reset pulse (815, 835, 855, 875) used during the greyscale update mode and (b) a standard reset pulse (610, 660) used during the monochrome update mode. Also, a monochrome update waveform (600, 650) includes a standard reset pulse (610, 660) whose duration is substantially less than a duration of an over-reset pulse (815, 835,... |

| Methods and apparatus for the micro-scale, dielectrophoretic separation of particles are provided. Fluid suspensions of particles are sorted and separated by dielectrophoretic separation chambers that have at least two consecutive, electrically coupled planar electrodes separated by a gap in a fluid flow channel.

| Driving method of an electrophoretic display with high frame rate and low peak power consumption | 20060291032 | 20061228 |
| An image is updated on a bi-stable display (310) such as an electrophoretic display by applying a drive waveform (900,920,940, 960; 1000, 1020,1040, 1060; 1100, 1120, 1140, 1160; 1220, 1240, 1260) with a compensating impulse (C) to at least one pixel (2) in the display.

| Method of compensating temperature dependence of driving schemes for electrophoretic displays | 20060291122 | 20061228 |
| An image is updated on a bi-stable display (310) such as an electrophoretic display by providing separate scaling functions (SF1, SF2) for scaling a duration of a reset pulse (R) and a duration of a driving pulse (D) in a drive waveform based on temperature (335). An absolute value of a slope with varying temperatures of the scaling factor (SF 1) for the reset pulse (R) is significantly greater than that of the scaling factor (SF2) for the driving pulse (D), while both scaling factors increase with decreasing temperature. Image update time (IUT) is significantly reduced at lower temperatures, while a range of variation of IUT across all temperatures is also reduced. Scaling functions (SF3, SF4) may also be used for scaling a duration of a... |
| Driving method for an electrophoretic display with high frame rate and low peak power consumption | 20060291125 | 20061228 |
| An image is updated on a bi-stable display (310) such as an electrophoretic display by using voltage waveforms (600, 620, 640, 660; 700, 720, 740, 760; 800, 820, 840, 860) that are configured such that voltage changes are constrained to a subset of possible voltage levels during specific frame times. The specific frame times may occur during datadependent portions of the waveforms, such as a reset portion (R) and/or a drive portion (D, D1, D2). Due to the reduced voltage swing, the supply voltage can be reduced, resulting in reduced power consumption. Moreover, the frame time (FT′) can be shortened during the data-dependent portions of the waveforms to increase the greyscale accuracy and number of grey levels. At other frames times, the voltage levels can vary... |

| Electrophoretic display unit | 20060262082 | 20061123 |
| Electrophoretic display units (1) are driven with a reduced amount of power by efficiently clocking a data signal into the data driving circuitry (30) only once and then supplying this data signal subsequently to two or more pixels (11) in two or more different lines. This can be done in case the pixels (11) in a same column require the same data pulse, like a shaking data pulse (Sh1, Sh2) or a reset data pulse (R). As a result, time is saved, which allows frame periods to be shorter. Even more time can be saved and even shorter frame periods are possible when combining the efficient clocking with the parallel driving of groups of lines (70-72).
