    Abstract: A privacy display comprises a polarised output spatial light modulator, reflective polariser, plural polar control retarders and a polariser. A birefringent surface relief diffuser structure is arranged to transmit light from the display with high transparency and provide diffuse reflection of ambient light to head-on display users. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss and with low diffusion, whereas off-axis light has reduced luminance and increased diffusion. Further, overall display reflectivity is reduced for on-axis reflections of ambient light, while reflectivity is increased for off-axis light. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction, increased frontal reflectivity and diffusion of ambient light. In a public mode of operation, the liquid crystal retardance is adjusted so that off-axis luminance and reflectivity are unmodified.

    Abstract: A reflective cover for a flat panel display includes a surface which is both reflective and transmissive. The cover includes a perimeter frame which is configured to couple to the surface around a perimeter of the surface. The perimeter frame further includes an engagement device. The engagement device is attached to the perimeter frame. The engagement device is configured to engage with a mounting bracket. A blackout shroud is coupled to the perimeter frame to form an opening. The opening is sized so that during mounting, the flat panel display is inserted into the opening and the engagement device engages with the mounting bracket.

  • Patent number: 10845025
    Abstract: A lighting assembly includes at least two LED elements arranged at a distance from each other. A diffusor element extends over the LED lighting elements. The diffusor element comprises first diffusion portions arranged in front of the LED lighting elements and second diffusion portions arranged in between the first diffusion portions. The first diffusion portions are disposed to cause a stronger optical diffusion than the second diffusion portions, thereby providing a more homogeneous appearance of light emitted from the diffusor element.

  • Patent number: 10787384
    Abstract: A glass sheet comprising at least one etched surface having a surface roughness defined, when measured on an evaluation length of 2 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm, by 0.02?Ra?0.4 microns and 5?RSm?30 microns. The glass sheet has excellent anti-sparkling properties together with an anti-glare effect. The texturing of the glass sheet may obtained by the process of carrying the glass sheet horizontally on a conveyor, pre-treating the surface to remove defects that may prevent subsequent uniform etching, etching the surface with aqueous solution containing hydrofluoric acid spread in an uniform layer over the surface of the sheet, maintaining the etching solution until the etching is ended, and drying the etched sheet.

  • Patent number: RE48690
    Abstract: Provided is a light unit including a plurality of LED light sources formed on a PCB, a resin layer stacked on the PCB to diffuse and guide emitted light forwards, and a diffusion plate having an optical pattern printed thereon to shield light emitted from the LED light sources. The optical pattern is composed of a diffusion pattern implemented as at least one layer, or a combination of the diffusion pattern layer and a light shielding pattern. The light unit forms an optical pattern for shielding or diffusing light on a surface of a light diffusion plate of the back-light unit, and combines a diffusion pattern and a metal pattern to attain uniformity of light and realize a yellow-light shielding effect, thus leading to a reliable light quality.
