Abstract: A digital display screen having an image displaying element and a backlighting device configured to backlight the image displaying element. The backlighting device defines a plurality of lighting zones, each lighting zone comprising one light source controllable to adjust the lighting intensity generated by the lighting zone. The lighting zones include at least one first lighting zone defining a first lighting surface having a first area and at least one second lighting zone defining a second lighting surface having a second area, the second area being strictly smaller than the first area.

Abstract: A system having an extended display surface that includes a main display surface, associated with at least one screen, and at least one peripheral display surface, associated with a peripheral display element, extending around at least part of the main display surface, and one or more backlighting units configured to illuminate these display surfaces. After receiving a plurality of digital images each represented by an image data array, the system performs an extraction from the image data array, of a main image data array of dimensions equal to the dimensions of the screen, and an extraction or generation of at least one complementary image data subarray, and a control of displaying the main image data array on the screen and controlling the backlighting units to perform a display of each complementary image data subarray on the corresponding peripheral display element.

Abstract: A trim element having an outer surface that is at least partially translucent, the outer surface defining a main display surface and a peripheral display surface, the peripheral display surface extending around at least a portion of the main display surface, a screen of a display device extending opposite the main display surface. The trim member includes an illumination device having a luminous sheet extending opposite the main display surface and the peripheral display surface so as to emit at least a first luminous signal onto the screen and at least a second luminous signal illuminating at least a portion of the peripheral display surface when the luminous sheet is activated.

Abstract: A trim element having a display area defined by a display device, and an edge piece that includes a peripheral area extending around at least part of the display area, the peripheral area being at least partly translucent, the display area and the peripheral area forming at least a part of an outer surface of the trim element. The trim element further includes an illumination device arranged to illuminate the display device to display images on the display area. The illumination device has a luminous sheet extending at least facing the display area and the peripheral area of the edge piece.

Abstract: Disclosed is a reflective diffraction grating including at least one intermediate metal layer arranged between the external reflective layer and a surface of the substrate including the grating lines, the external reflective layer being consisted of a first metal and the intermediate metal layer being consisted of another metal, the other metal having a higher electron-phonon coupling coefficient than the electron-phonon coupling coefficient of the first metal or metal alloy, the external reflective layer having a thickness in a range having a lower limit determined by a reflection coefficient of the first metal and an upper limit determined by a thermal diffusion length of the first metal, and the intermediate metal layer having another thickness greater than a minimum value in such a way as to increase the high peak power ultrashort pulse light flux resistance of the reflective diffraction grating.

Abstract: A method of characterizing a pattern includes determining an image of the contour of the pattern to be characterized with an imagining instrumentation; processing the image, the processing including determining a plurality of points located along the contour and sampled according to a given sampling interval; for each point, identifying a point located on a reference contour and corresponding to the same sampling interval number and determining a dimensionless intermediate coefficient representative of the deviation between the point and the corresponding point on the reference contour; determining a final dimensionless coefficient on the basis of the set of intermediate coefficients corresponding to the plurality of points, the final coefficient being representative of the deviation between the contour of the pattern to be characterized and the reference contour.
