Publication number: 20080224989Abstract: An electrophoretic display, in which a driving method is employed whereby a sequence of discrete picture potential differences in the form of a driving waveform is supplied for enabling the charged particles (6) of the display to occupy a position for displaying an image, the position being one of a number of positions between the electrodes (3, 4). The driving waveform consists of a sequence of image update signals including a picture potential difference, the image update signals being separated by dwell times, and the method includes the step of generating one or more shaking pulses during the dwell times. Such shaking pulses may be generated immediately after each image update signal or they may comprise regular shaking pulses generated at predetermined intervals along the waveform.Type: ApplicationFiled: January 7, 2005Publication date: September 18, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONIC, N.V.Inventors: Guofu Zhou, Mark Thomas Johnson, Neculai Ailenei, Johannes Petrus Van De Kamer, Peter Alexander Duine, Anthonie Hendrik Bergman

Patent number: 7370987Abstract: The display panel (21) comprises a light guide (2), a second plate (4) and a movable element (3) between both plates for locally decoupling light out of the light guide (2). Voltages, applied to electrodes (5,6 resp. 25), associated with the light guide (2), the second plate (4) and the movable element (3), locally bring the movable element (3) into 5 contact with the light guide plate (2) or the second plate (4). If, between the light guide (2) and the first electrodes (5) a layer (51) is present with a second refractive index being smaller than the first refractive index of the light guide (2), and the light guide (2) is positioned between the first electrodes (5) and the movable element (3), absorption of the light transported through the light guide plate (2) is reduced, providing a display panel (21) with 10 improved power efficiency.Type: GrantFiled: April 22, 2003Date of Patent: May 13, 2008Assignee: Koninklijke Philips Electronics N.V.Inventors: Siebe Tjerk De Zwart, Peter Alexander Duine, Antonius Hendricus Maria Holtslag, Gerrit Oversluizen

Publication number: 20040263076Abstract: A display device comprising a first and a second set of electrodes (2, 5), and a plurality of light-emitting elements (3), arranged between said sets of electrodes. The display further comprises an electromechanically operable foil (6), located between said light-emitting elements (3) and said second set of electrodes, with a conducting layer facing the light-emitting elements (3). The foil (6) is arranged to place the conducting layer (7) in contact with selected ones of said light-emitting elements (3), thereby closing a circuit from said first set of electrodes (2), via said elements (3), to said conducting layer (7). Thus, the foil acts as a plurality of “switches”, connecting selected light-emitting elements to the conducting layer. This function can be used for controlling the light-emitting elements with a higher degree of accuracy.Type: ApplicationFiled: July 12, 2004Publication date: December 30, 2004Inventors: Siebe Tjerk De Zwart, Roy Van Dijk, Ramon Pascal Van Gorkom, Peter Alexander Duine

Patent number: 6310725Abstract: A description is given of a switching device (1) comprising a transparent substrate (3) and a switching film (5) which incldes a hydride of a trivalent metal, such as gadolinium, and which is covered with a palladium layer (7). Between the substrate (3) and the switching film (5) a thin magnesium layer (4) is interposed. By exchange of hydrogen, the switching film can be reversibly switched from a transparent state to a highly reflective state. The conversion between both states is reversible, and this phenomenon can be used, for example, in a luminaire or for climate control.Type: GrantFiled: November 13, 2000Date of Patent: October 30, 2001Assignee: U.S. Philips CorporationInventors: Peter Alexander Duine, Paul Van Der Sluis
