Patent number: 8054421Abstract: 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.Type: GrantFiled: April 1, 2008Date of Patent: November 8, 2011Assignee: Adrea, LLCInventors: Sander Jurgen Roosendaal, Martinus Hermanus Wilhelmus Maria Van Delden

Patent number: 7697194Abstract: An improved moving particle display device having a plurality of pixels (12, 14; 21, 22, 23, 24) is disclosed. The pixels are formed between first (1) and second (2) substrates that are spaced apart by a plurality of partition walls (10; 20). Each pixel comprises charged particles (115) that are movable under the influence of primary electric field lines of force (16) to set the optical appearance of the pixel. The pixels further comprise blocking material (210) for physically blocking the charged particles from entering predetermined regions (200) of the pixels that are likely to have secondary electric field lines of force (18) that extend through the partition walls. Hence, the charged particles are blocked from entering regions of the pixels having secondary electric field lines of force that could attract the particles to move into any gaps (9) that exist between the partition walls and the substrates.Type: GrantFiled: August 3, 2007Date of Patent: April 13, 2010Assignee: Koninklijke Philips Electronics N.

Publication number: 20100020064Abstract: An electrophoretic display device is driven by carrying out a first display addressing cycle (FIG. 3A), in which the display is addressed as a first set of row groups (52), the same column data set being applied to each row of the row group simultaneously. The number of row groups (52) is less than the number of rows (50), such that at least one row group comprises a plurality of rows. At least one further display addressing cycle (FIG. 3B) addresses all rows of the display with independent image data. This method addresses groups of rows together using the same column data, and thereby reduces the addressing time. The image is presented after the first addressing cycle as a low resolution image, in particular with low vertical resolution. The subsequent addressing cycles then progressively improve the image quality to the final desired image.Type: ApplicationFiled: September 5, 2007Publication date: January 28, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Sander Jurgen Roosendaal, Martinus Hermanus Wilhelmus Maria Van Delden, Mark Thomas Johnson

Publication number: 20100015557Abstract: A method for forming a sealed cell structure is disclosed. The sealed cell structure comprises first (10) and second (12) substrates that are spaced apart by a plurality of partition walls (14). The partition walls define a plurality of cells (18, 19) between the first and second substrates. At least one of the substrates and the partition walls have a layer (16, 22, 30) of photo-embossing material on them. A latent image is written (112) onto the photo-embossing material, and then the image is developed, thereby causing expansion of the photo-embossing material in the areas (114) according to the pattern of the latent image. The expansion of the photo-embossing material causes the cells to be sealed apart from one another.Type: ApplicationFiled: August 17, 2007Publication date: January 21, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Mark Thomas Johnson, Martinus Hermanus Wilhelmus Maria Van Delden, Dirk Jan Broer

Publication number: 20090251405Abstract: A colour reflective display device uses two colour absorbing components (40,42), and the quantity of the two colour absorbing components within the pixel aperture can be independently controlled. The first colour absorbing component has a colour (C) at a point lying substantially between the green and blue regions of an (x,y) chromaticity diagram, and the second colour absorbing component has a colour (O) at a point lying substantially between the green and red regions of an (x,y) chromaticity diagram. The invention provides a colour active light shutter layer with only two colour components. One is selected to be near cyan and the other is selected to be near orange, and these together enable a range of colours to be produced which enables good quality colour images to be produced.Type: ApplicationFiled: August 28, 2007Publication date: October 8, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Sander Jurgen Roosendaal, Martinus Hermanus Wilhelmus Maria Van Delden
