Patent number: 7710370Abstract: The invention relates to a display device assembly (1) comprising a flexible display device (2) being rollable around an axis (5), the flexible display (2) having a front side (3) and a back side (4), one of the sides (3,4) being provided with distance elements (7, 7?,80) for preventing a direct contact between the front side (3) and the back side (4). By preventing the front and back side to contact each other the amount of display damage is significantly reduced as compared to conventional roll-up displays. An advantageous embodiment comprises a display device assembly in which the spacer elements are shaped in the form of bars (7, 7?). In a further advantageous embodiment of the display assembly the distance elements comprise a protection foil (80).Type: GrantFiled: October 27, 2003Date of Patent: May 4, 2010Assignee: Polymer Vision LimitedInventors: Peter Jan Slikkerveer, Bas Jan Emile Van Rens

Publication number: 20090153236Abstract: The available battery power on autonomously powered mobile electronic devices, in particular smartcards, is very small but requires a very long shelf life. Thus, even very small rest currents are a big power issue. The invention discloses a power save circuit and method, where a single power switch, e.g. a FET or a MEM switch, can be used to detach the power supply (?) from the whole system and allow the lowest current possible. Further, a combination with a double action button and integration of the power switch provides a solution with a minimum number of components and interconnects. An option for “system wake-up at any button” enables additional power saving during use, without inconvenience to the user.Type: ApplicationFiled: October 18, 2005Publication date: June 18, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Franciscus Antonius Kneepkens, Peter Jan Slikkerveer, Pawel Musial

Publication number: 20080212165Abstract: A bistable display device comprises a first substrate (22) carrying, on one side, a plurality of electrode segments (28, 30) and supply lines (26) connecting to the segments. The electrode segments comprise a first set of electrode segments (30) which define the display regions for providing information to the user, and a second set of electrode segments (28) which defines a background display region. Each supply line (26) is sandwiched laterally between electrode segments such that the visual display output in the region of the supply line is substantially the same as that in the region of the electrode segments which sandwich the supply line. The electrode segments which sandwich the supply lines dominate the electric field distribution in the display medium layer so that visibility of the supply lines is reduced, even though they are formed on the same substrate surface as the electrode segments.Type: ApplicationFiled: June 12, 2006Publication date: September 4, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Henri Jagt, Guofu Zhou, Peter Jan Slikkerveer

Publication number: 20080165398Abstract: The present invention relates to a security display assembly (10; 50) comprising a display (12; 52) for providing a display image and a hologram (14; 54) for providing a holographic image. The hologram is integrated into the display and occupies essentially the same or less area as the display. Integrating the hologram into the display makes counterfeiting of a product provided with the security display assembly more difficult. It also saves space on the product onto which the security display assembly is provided. The invention also relates to a smart card (20) comprising such a security display assembly.Type: ApplicationFiled: June 28, 2006Publication date: July 10, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Henri Jagt, Peter Jan Slikkerveer

Patent number: 7296519Abstract: The invention relates to a method for transferring a pattern from a stamping surface (31) of a stamp (30) to a receiving surface (21) of a substrate (20). The pattern is transferred to the receiving surface (21) by successively bringing portions of the pattern within such a range of the receiving surface (21) during a certain period, that the pattern is locally transferred from the stamping surface (31) to the receiving surface (21). The individual portions can be moved by means of individual actuators (50). By applying the method, the transfer of the pattern can be performed according to a wave, which is for example ring-shaped, moving from the center of the receiving surface (21) to the circumference, or linear, moving from side of the receiving surface (21) to an opposite side.Type: GrantFiled: May 26, 2003Date of Patent: November 20, 2007Assignee: Koninklijke Philips Electronics N.V.Inventors: Marinus Josephus Jakobus Dona, Martin Hillebrand Blees, Michel Marcel Jose Decre, Patrick Petrus Johannes Van Eerd, Richard Joseph Marinus Schroeders, Teunis Johannes Antonius Heijmans, Christiaan Leonard Jozef Janssen, Peter Jan Slikkerveer

Patent number: 6753933Abstract: A bistable liquid crystal display device can be erased by the application of a mechanical pressure P at a section 20 of the display. The pressure induces a flow of the liquid crystal (5) material into an expansion chamber (22). The induced flow causes a transition from the non-reflecting to the reflecting state, thus eliminating the necessity of high voltage erasing voltages.Type: GrantFiled: August 26, 2002Date of Patent: June 22, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Peter Albert Cirkel, Petrus Cornelis Paulus Bouten, Peter Jan Slikkerveer, Giovanni Nisato

Patent number: 6739255Abstract: The stamp (10) for use in a lithographic process, such as patterning a surface layer, of the invention has a stamp body (1) with a first (11) and a second side (12), at which first side (11) a printing face (2) is present and at which second side (12) a stack of a carrier body (4) and a reservoir (3) for liquid are present. The carrier body contains channels (5) in order that the liquid can be transported from the reservoir (3) to the stamp body (1) and further to the printing face (2). The stamp may be embodied as a cylinder, allowing a continuous lithographic printing process. This process results in patterns on a micron or submicron scale. The stamp (10) may furthermore be included in a larger apparatus.Type: GrantFiled: November 21, 2001Date of Patent: May 25, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Martin Hillebrand Blees, Peter Jan Slikkerveer, Sigrid Maria Roman Gelderland
