Patent number: 7903335Abstract: A mirror device which can be simultaneously used for display purposes, based on e.g. an LCD display with a polarizing mirror placed in front of it. The reflectivity of such a mirror display is enhanced by providing at its non-viewing side a further polarizing mirror Color absorption in the display is prevented by placing the color filter or a color (sequential) backlight behind this reflective polarizer at the back of the display.Type: GrantFiled: November 3, 2004Date of Patent: March 8, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Armanda Cinderella Nieuwkerk, Emiel Peeters, Hugo Johan Cornelissen, Martinus Hermanus Wilhelmus Maria Van Delden

Patent number: 7728927Abstract: A mirror device may be simultaneously used for display purposes, based on e.g. an LCD display with a polarizing mirror placed in front of it. The polarizing mirror has the characteristics that it does not disturb the transmission of the light from the display to the viewer, but does reflect the incident light.Type: GrantFiled: August 20, 2004Date of Patent: June 1, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Armanda Cinderella Nieuwkerk, Martinus Hermanus Wilhelmus Maria Van Delden, Maria Henrica Wilhelmina Antonia Van Deurzen

Patent number: 7636195Abstract: A mirror device (1) which can be simultaneously used for display purposes, based on e.g. an LCD display (5) with a polarizing mirror (2) placed in front of it. When the surface area occupied by the display is smaller than the surface area of the mirror, the smaller display can be easily recognized at the front of the mirror. This is masked by introducing absorbing polarizers (30, 40).Type: GrantFiled: January 4, 2005Date of Patent: December 22, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Armanda Cinderella Nieuwkerk, Martinus Hermanus Wilhelmus Maria Van Delden, Emiel Peeters, Bianca Maria Irma Van Der Zande

Publication number: 20080252832Abstract: An image display apparatus (100) is disclosed. The image display apparatus (100) comprises: a display device (104) for displaying an image, by emission of display light in a first direction; a scattering layer (102) disposed in front of the display device (104), for scattering a portion of the ambient light; and a reflective layer (106) disposed in between the display device (104) and the scattering layer (102) for reflecting a portion of the scattered ambient light into the first direction.Type: ApplicationFiled: October 2, 2006Publication date: October 16, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Armanda Cinderella Nieuwkerk, Hendrik De Koning, Dirk Jan Broer, Cornelis Teunissen

Publication number: 20080252833Abstract: The present invention relates to a mirror device, the reflectivity of which may be varied by means of applying a voltage. According to an aspect of the invention, there is provided a mirror device, the reflectivity of which may be varied by means of applying a voltage, comprising a cholesteric filter (33) which is arranged to be gradually switchable between a reflective and a transparent state by varying said voltage, and a display device (32) arranged to be at least partly covered by the cholesteric filter, wherein said display device is visible when the cholesteric filter is set in the transparent state and hidden when the cholesteric filter is set in the reflective state.Type: ApplicationFiled: August 28, 2006Publication date: October 16, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Armanda Cinderella Nieuwkerk, Martinus Hermanus Wilhelmus Maria Van Delden, Rifat Ata Mustafa Hikmet, Bente Adriaan Bordes

Publication number: 20080252822Abstract: An electro-optical switch, which can be switched between a substantially transparent state and a scattering state on basis of respective applied voltages, is disclosed. The electro-optical switch has a reflection-voltage curve that is steep enough to allow multiplexing. The electro-optical switch comprises: a scattering layer (302) comprising a liquid crystal-polymer composite; and a reflective layer (306) for reflecting a portion of scattered light back towards the scattering layer (302).Type: ApplicationFiled: October 2, 2006Publication date: October 16, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Hendrik De Koning, Leendert Marinus Hage, Armanda Cinderella Nieuwkerk, Dirk Jan Broer, Martin Jacobus Johan Jak

Patent number: 6583837Abstract: In a vertical aligned LCD the other substrate has further protrusion parts e.g. parallel to the gate buses or source buses, in addition to the protrusion parts parallel to slits of pixel electrodes. By the further protrusion, when a voltage is applied to the liquid crystal layer, it becomes easy to align axes of liquid crystal molecules in one direction, so that transmittivity of light which travels through liquid crystal panel becomes high.Type: GrantFiled: June 29, 2001Date of Patent: June 24, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Masakazu Fukumoto, Masahiro Yoshiga, Mark Thomas Johnson, Johannes Albertus Matthijs Maria Van Haaren, Dirk Kornelis Gerhardus De Boer, Jeffrey Alan Chapman, Armanda Cinderella Nieuwkerk
