20100053230 | DISPLAY DEVICE USING MOVEMENT OF PARTICLES - A method is provided for driving a display device comprising an array of rows and columns of display pixels, each pixel comprising particles which are moved to control the display state of the pixel. A display addressing mode is provided for writing an output image on a display, which has a line-by-line partial writing operation (to a temporary storage electrode) and a parallel writing operation to finish off the writing of the display. This enables a reduction in addressing time, as the distance of movement of the particles is reduced during the line-by-line phase, so that the line time can be reduced. The writing is then completed with a parallel phase for all the display, and the overall writing time is reduced. A further mode is provided to enable even more rapid writing of lines, and this can be used to modify images even more rapidly, but only with simple line-based modifications. | 03-04-2010 |

20100060628 | IN-PLANE SWITCHING ELECTROPHORETIC COLOUR DISPLAY - The invention relates to an electrophoretic color display panel, the display panel comprising at least one pixel ( | 03-11-2010 |
20100060673 | DISPLAY DEVICE USING MOVEMENT OF PARTICLES - A method of driving a display device uses a first display addressing mode, in which the display is addressed sequentially in rows, and wherein a first image is displayed with a first contrast ratio between the lightest and darkest pixels, and with a brightest pixel output state, a darkest pixel output state and a plurality of intermediate grey level output states. In a second mode, the display is addressed sequentially in rows, and a second image is displayed with a second contrast ratio between the lightest and darkest pixels which is greater than the first contrast ratio. | 03-11-2010 |
20100218889 | Lateral Ion Pumping in Liquid Crystal Displays - The present invention relates to the removal of ion contaminations from liquid crystal layers in liquid crystal display devices. The ions are removed by means of so called ion pumping, which utilizes the anisotropic viscosity of liquid crystals. The ions are pumped up and down in the liquid crystal layer by means of an alternating electric filed. The alternating electric field simultaneously alters the alignment of directors in the liquid crystal. The viscosity in the liquid crystal is related to the director directions, and the ions are thereby moved in non-closed trajectories. The inventive ion pumping can be further improved using an asymmetric or biased alternating electric field. | 09-02-2010 |
