20120212798 | ELECTROPHORETIC ELEMENT AND DISPLAY DEVICE - An electrophoretic element includes: an electrophoretic particle; a porous layer formed of a fibrous structure containing a non-migrating particle having optical reflective characteristics different from those of the electrophoretic particle and having a plurality of pores; and a partition that is partially adjacent to the porous layer and defines a space for accommodating the electrophoretic particle. An area rate of the pores per unit area of the porous layer is small in an adjacent region where the partition is adjacent to the porous layer compared with in a non-adjacent region where the partition is not adjacent to the porous layer. | 08-23-2012 |
20120250138 | ELECTROPHORETIC DEVICE, DISPLAY UNIT, AND ELECTRONIC UNIT - An electrophoretic device includes: an electrophoretic particle; a porous layer formed of a fibrous structure containing a non-electrophoretic particle having optical reflection characteristics different from those of the electrophoretic particle; and a dividing wall adjacent to the porous layer. The electrophoretic particle, the porous layer, and the dividing wall are in an insulating liquid. Volume resistivity of the fibrous structure is larger than volume resistivity of the insulating liquid, and volume resistivity of the dividing wall is larger than the volume resistivity of the insulating liquid. | 10-04-2012 |
20120314273 | ELECTROPHORETIC DEVICE, DISPLAY UNIT, AND ELECTRONIC UNIT - An electrophoretic device includes an electrophoretic particle, a porous layer formed of a fibrous structure containing a non-electrophoretic particle having optical reflection characteristics different from optical reflection characteristics of the electrophoretic particle, and a pair of electrodes arranged with the porous layer in between. The porous layer is adjacent to one or both of the pair of electrodes. | 12-13-2012 |

20140111409 | IMAGE DISPLAY UNIT, METHOD OF DRIVING IMAGE DISPLAY UNIT, SIGNAL GENERATOR, SIGNAL GENERATION PROGRAM, AND SIGNAL GENERATION METHOD - An image display unit, includes: an image display section having pixels each including red, green, blue, and white pixels; and a signal generating section configured to generate red, green, blue, and white sub-pixel signals, the signal generating section being configured to determine values of the red, green, and blue sub-pixel signals R | 04-24-2014 |
20140146099 | DISPLAY UNIT, ELECTRONIC APPARATUS, AND METHOD OF DRIVING DISPLAY UNIT - A display unit includes a plurality of pixels arranged in a two-dimensional matrix. An image is displayed in a first display mode and a second display mode. In the first display mode, one pixel is configured of a set including J (where J is an integer of 2 or more) first unit pixels emitting a first color, J second unit pixels emitting a second color, and J third unit pixels emitting a third color, and image display is performed through control of operation of each of the unit pixels. In the second display mode, one pixel is configured of a set including j (where j is an integer of 1 or more and less than J) first unit pixels, j second unit pixels, and j third unit pixels, and image display is performed through control of operation of each of the unit pixels. | 05-29-2014 |
20140233088 | DISPLAY UNIT AND METHOD OF DRIVING SAME, AS WELL AS ELECTRONIC APPARATUS - Provided is a display unit capable of improving display performance. The display unit includes an electrophoretic particle disposed between a pair of electrodes for each pixel; and a voltage control circuit applying a voltage for each pixel, to move the electrophoretic particle. The voltage control circuit counts, for each pixel, a number of applications of a first voltage and a number of applications of a second voltage, the first voltage being applied to move the electrophoretic particle towards one of the electrodes, and the second voltage being applied to move the electrophoretic particle towards the other of the electrodes. Further, at an arbitrary timing following start of display, when the number of applications of the second voltage in part of pixels is smaller than that in other pixel, the voltage control circuit applies the second voltage to the pixel with the smaller number of applications, to bring this smaller number of applications closer to the number of applications in the other pixel. | 08-21-2014 |
20140293401 | DISPLAY UNIT AND ELECTRONIC APPARATUS - An electrophoretic display device comprising a plurality of first particles configured to migrate between a remain region and a display region in response to an electric field, as well as a plurality of non-migrating second particles fixedly disposed between the remain and display regions and configured to (a) allow the plurality of first particles to pass between the remain and display regions in response to the electric field, and (b) cover the plurality of first particles when the first particles are disposed in the remain region. | 10-02-2014 |
