Abstract: A back-lighting device comprises a light source configured to emit a source beam, a reflector configured to reflect at least a part of the source beam into a reflected beam, an integrally formed component comprising, on a first side, a reflective polarizer and, on a second side opposite the first side, an optical diffuser, said component being configured to receive and transmit at least a part of the reflected beam, characterized in that the first side of the component is placed facing the light source. An image-generating device, a head-up display and a process for manufacturing a component for the back-lighting device are disclosed herein.

Abstract: An image generating device is disclosed having a first light source configured to generate a first upstream light beam, a second light source configured to generate a second upstream light beam, and an array of variable transmittance elements configured to selectively receive and transmit the first upstream light beam and to selectively receive and transmit the second upstream light beam so as to form, respectively, a first downstream light beam forming a first image and a second downstream light beam forming a second image. A head-up display including an image generating device is also disclosed.
