Patent number: 8226792Abstract: A method for manufacturing a flooring product with integrated circuitry, comprising the steps of providing a plurality of pieces (6), stacking said pieces on top of each other, displaced in relation to each other to form an offset stack (10), and compressing said offset stack to form said flooring product. The method further comprises arranging flexible circuitry (7) on an upper surface of at least one piece, so that, when said pieces are stacked, a first portion (7a) of flexible circuitry on the at least one piece is exposed, said first portion (7a) including circuitry for interacting with the environment. By arranging the circuitry in the flooring during such a manufacturing process, a flooring product is achieved where only a portion of the circuitry is exposed, and another portion is embedded in the flooring.Type: GrantFiled: July 28, 2008Date of Patent: July 24, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Antonius Hendricus Maria Holtslag, Evert Jan Van Loenen, Georg Sauerlaender, Harald Josef Gunther Radermacher, Matheus Franciscus Antonius Van Hugten

Publication number: 20090146933Abstract: A liquid crystal display comprising first and second liquid crystal display panel (1, 3), each defining an array of picture elements (13, 15). The resolution of the image displayed on the second liquid crystal display panel (3) is lower than that of the image displayed on the first liquid crystal display panel (1). The picture elements (15) of the second liquid crystal display panel (3), located between the first liquid crystal display panel (1) and backlighting means (2) may be relatively large and preferably partially overlap at least in one direction. A charge is selectively applied to the picture elements (15) of the second liquid crystal display panel (3) corresponding to the relatively darker portions of the image to be displayed on the first liquid crystal panel (1), so as to at least limit the amount of light reaching these portions of the first liquid crystal display panel (1) and thereby increasing the contrast trio of the device.Type: ApplicationFiled: November 24, 2005Publication date: June 11, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Hugo Matthieu Visser, Mark Thomas Johnson, Nebojsa Fisekovic, Antonius Hendricus Maria Holtslag, Wilbert L.

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

Patent number: 7045947Abstract: The invention relates to a vacuum display device comprising a display screen (30) having picture elements (35), cathode means (20) for generating a plurality of electron beams (EB), each corresponding to one of the picture elements (35), and addressing means (41,42) for addressing the picture element (35) through modulation of the intensity of an electron beam corresponding to the picture element (35). A channel structure (10) is arranged adjacent the cathode means (20). The channel structure (10) comprises a plurality of electron beam guidance cavities (15), each corresponding to one of the picture elements (35), and protects the cathode means (20) from incident ions. The exit (17) of the cavity (15) is smaller than the entrance (16), so that an electron beam (EB) exiting from the cavity (15) has a particularly high brightness and spatial uniformity.Type: GrantFiled: October 24, 2002Date of Patent: May 16, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Nijs Cornelis Van Der Vaart, Martin Gerard Hendrik Hiddink, Siebe Tjerk De Zwart, Antonius Hendricus Maria Holtslag, Theunis Siemen Baller, Hans-Helmut Bechtel, Georg Friedrich Gaertner

Patent number: 6856328Abstract: Logos may be present in images transmitted by television stations. These logos are often present in the corners (102, 104) of an image (100) for a long time. They do not move and may comprise saturated colors. This results in burn-in effects in emissive displays because the logos provide the same display load at the same location for a relatively long period of time. The burn-in effect can be prevented by detecting the logos in the corners (102, 104) of the image (100) and reducing their intensity to the average display load.Type: GrantFiled: October 26, 2001Date of Patent: February 15, 2005Assignee: Koninklijke Philips Electronics N.V.Inventor: Antonius Hendricus Maria Holtslag

Patent number: 6512336Abstract: The invention relates to an AC plasma display panel (12) of the surface discharge type, and more specifically to the structure of the address electrodes (5) of said panel, and to a method of driving said panel. According to the invention, only one address electrode (5) is used for one out of every two columns. Scan (8) and common (7) electrodes may comprise transparent parts (11). These parts (11) may extend over one out every two cells, in a checkerboard fashion.
