Patent number: 11009744Abstract: A reflective display device and a method of making or operating the display device, where the reflective display device includes a spatial reflective light valve, at least one light emitting element being positioned in front of the spatial reflective light valve and light shaping device to direct the light generated by the at least one light emitting element in defined directions with respect to the spatial reflective light valve. This makes use of the fact that the contrast improves and the diffuse reflection component of the reflective display increases when the illumination direction gets closer to the perpendicular direction but rays close to the perpendicular direction need to be reduced in intensity or better still avoided to reduce the specular component. This can use illumination directions close to the perpendicular direction while preventing or reducing specular reflection within a range of incident angles.Type: GrantFiled: July 25, 2017Date of Patent: May 18, 2021Assignee: BARCO N.V.Inventors: Claude Daniel Tydtgat, Bart Van Den Bossche

Patent number: 7192141Abstract: An optical design is described to be used in a color projection system. The system comprises a white light source (52), a light splitting means to split the white beam into color subbeams, optical components to direct each color subbeam on a light modulating means (56) and a dichroic prism (70). The light splitting means and the optical components are arranged such that each of the images of the color subbeams imaged on the light modulating means (56) has equal size and orientation, i.e. such that the magnification of the color subimage on the light modulating means (56) is equal. This is obtained by providing equal light paths for each color subbeam or by providing optical components such that either all different color images on the screen are inverted or none of the different color images are inverted.Type: GrantFiled: February 24, 2004Date of Patent: March 20, 2007Assignee: Barco N.V.Inventors: Bart Van Den Bossche, Koen Beyers, Koen Van Belle, Peter De Meerleer
