Patent Number Title Of Patent Date Issued
8228290 Electrophoretic display device with overlapping first and second row and column electrodes July 24, 2012
An electrophoretic display device comprises an array of rows and columns of display pixels. Each pixel comprises first and second row electrodes (12a, 12b) and first and second column electrodes (14a, 14b). Each row and column electrode has a branch (12a', 12b', 14a', 14b') so that four
8149208 Electrophoretic display panel April 3, 2012
The electrophoretic display panel (1) for displaying a picture and a subsequent picture has drive means (100) which are able to control for each pixel (2) the potential difference to have a picture value to provide the pixels (2) with a respective picture appearance being either extr
8095949 Electronic book with restricted access features January 10, 2012
A viewer for displaying electronic books and having various features for restricting access to their content. A user may assign ratings to stored electronic books, or use standard ratings, and assign access levels to potential users. The ratings and access levels determine which electron
8073695 Electronic book with voice emulation features December 6, 2011
A method and system for providing text-to-audio conversion of an electronic book displayed on a viewer. A user selects a portion of displayed text and converts it into audio. The text-to-audio conversion may be performed via a header file and pre-recorded audio for each electronic bo
8054421 Reflective display panel and method for manufacturing such a display panel November 8, 2011
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
7995029 Display apparatus with a display device and method of driving the display device August 9, 2011
A display apparatus including a matrix display device with pixels wherein particles move in a fluid between electrodes. An optical state of the pixels is defined by a value of a drive voltage and a duration of a drive period during which the drive voltage is present across the pixel. A
7876305 Electrophoretic display device and driving method therefor January 25, 2011
An electrophoretic display has at least one pixel (18) which comprises electrophoretic material (8, 9), a first electrode (6) and a second electrode (5). An addressing circuit (16, 10) addresses the at least one pixel (18) by applying between the first electrode (6) and the second el
7872633 Electrophoretic display and a method of shaking an electrophoretic display from an extreme posit January 18, 2011
An electrophoretic display having charged particles that are able to occupy, between a first and second electrode, two limit positions and intermediate positions between the two limit positions which are defined by a drive voltage. An addressing circuit generates the drive voltage wa
7864161 Use of a two finger input on touch screens January 4, 2011
