Abstract: An image-generating device is disclosed. The image-generating device includes a light source configured to emit a light beam, a reflector configured to reflect the light beam toward an array of elements with variable transmittance, and a protective cover for the array of elements with variable transmittance attached to the array of elements with variable transmittance. The device includes a main housing configured to be attached to a support of the light source. The light source and the reflector are clamped between the support and the main housing attached to the support. The array of elements with variably transmittance are clamped between the main housing and the protective cover attached to the main housing.

Abstract: An image generating device is disclosed having a light source configured to produce an upstream light beam, and an array of elements with variable transmittance configured to selectively receive and transmit the upstream light beam so as to form a downstream light beam forming an image. A downstream face of the array of variable transmittance elements is in contact with an at least partially transparent plate configured to limit heating of the array of variable transmittance elements. A downstream face of the partially transparent plate is in contact with a cold face of a thermoelectric cooling module.

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.
