A system such as a vehicle, building, or electronic device system may have a support structure with one or more windows. The support structure and window may separate an interior region within the system from a surrounding exterior region. Control circuitry may receive input such as user input and may adjust an adjustable layer in the window based on the input. The adjustable layer may be an adjustable light transmission layer. The adjustable light transmission layer may have a polymer matrix layer with embedded guest-host liquid crystal cells. Each cell may have liquid crystal material and dichroic dye. The adjustable light transmission layer may be operated in a dark state to prevent light from passing through the window, a clear state in which the window passes light, and intermediate states that exhibit intermediate light transmission levels.

Systems with adjustable window transmission

A system such as a vehicle, building, or electronic device system may have a support structure with one or more windows. The support structure and window may separate an interior region within the system from a surrounding exterior region. Control circuitry may receive input such as user input and may adjust an adjustable layer in the window based on the input. The adjustable layer may have a polymer matrix layer with embedded cells. The cells may include intermixed guest-host liquid crystal cells and liquid crystal cells. The guest-host liquid crystal cells and liquid crystal cells may have different liquid crystal materials and/or different sizes that allow the guest-host liquid crystal cells and liquid crystal cells to electrically switch states at different respective threshold voltages. Based on the user input or other input the control circuitry can adjust a drive signal across the adjustable layer to change light transmittance and haze.

Systems with adjustable window transmission and haze

A switchable panel is described that includes exterior layers, a switchable component disposed between the exterior layers, a lamination frame extending from outer edges of the switchable component to outer edges of the panel between the exterior layers, and spacers embedded within the lamination frame. The spacers are configured to prohibit the exterior layers from moving toward each other at the outer edges of the panel when a central portion of the panel experiences tension.

Switchable panel with tension control components

A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The illumination optics may produce illumination that is modulated by the fLCOS panel to produce image light. The waveguide may direct the image light towards an eye box. The fLCOS panel may include a ferroelectric liquid crystal (fLC) layer and a backplane. In order to maximize the reflectance of the fLCOS panel and thus the optical performance of the display, the backplane may be a silver backplane or a dielectric mirror backplane. In addition, the backplane may have a cell gap that is equal to a wavelength divided by four times the birefringence of the fLC layer. In order to further optimize the optical performance of the display module, the wavelength used in determining the cell gap may be a green wavelength between 500 nm and 565 nm.

Optical systems having fLCOS display panels

A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The illumination optics may include a red, green, and blue light sources. The fLCOS panel may produce image light by modulating a series of image frames onto illumination light. Control circuitry may control the illumination optics to produce the illumination light for each image frame in the series of image frames according to a green-heavy illumination sequence that includes first, second, and third time periods. The green light source may be active during each of the first, second, and third time periods. This may allow the green light source to be driven with a lower current density than the other light sources without significantly reducing image quality at an eye box. The lower current density may match the peak efficiency of the green light source, thereby minimizing power consumption by the display.

Optical systems with green-heavy illumination sequences for fLCOS display panels

A display may have display layers that form an array of pixels. An angle-of-view adjustment layer may overlap the display layers. The angle-of-view adjustment layer may include an array of adjustable light blocking structures formed from electrochromic material. The electrochromic material may be interposed between first and second electrode layers. When it is desired to operate the display in a private viewing mode, control circuitry may apply a current to the first and second electrodes that causes the electrochromic material to become more opaque, thereby restricting the angle of view of the display. When it is desired to operate the display in a public viewing mode, control circuitry may apply a current to the first and second electrodes that causes the electrochromic material to become more transparent, thereby opening up the angle of view of the display.

Displays with adjustable angles of view

A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The display may include a temperature sensor that gathers temperature sensor data. Control circuitry may select a non-square wave drive voltage waveform based on the gathered temperature sensor data and/or based on frame history information for the fLCOS display panel. The control circuitry may control the fLCOS panel to produce image light by driving the fLCOS panel using the selected non-square wave drive voltage waveform. The non-square wave drive voltage waveform may be an overdrive waveform or an underdrive waveform. This may serve to optimize the reflectance of the fLCOS display panel and thus the optical performance of the display module regardless of operating temperature and frame history.

Optical systems having overdriven fLCOS display panels

A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. A twisted nematic cell may be optically interposed between the fLCOS panel and the waveguide. A birefringent crystal may be optically interposed between the cell and the waveguide. The cell may have a first state in which the cell transmits the image light with a first polarization and a second state in which the cell transmits the image light with a second polarization. The crystal may transmit the image light within spatially offset beams based on polarization. In another arrangement, a quarter waveplate may be optically interposed between the cell and the waveguide and a geometric phase grating may be optically interposed between the quarter waveplate and the waveguide. Control circuitry may toggle the cell between the first and second states to maximize the effective resolution of images at an eye box.

Optical systems with pixel shifting structures

An electronic device may have a display with an array of display pixels. To increase the efficiency of the display, the display may also include an array of microlenses. Each microlens may overlap and focus light from a respective pixel. Pixels for one of the colors of light may have a high aspect ratio. These pixels may be covered by two microlenses or a single cylindrical microlens. The microlens dimensions may be tuned to mitigate non-uniformities in the brightness profiles of the pixels. The microlens edges may be laterally shifted towards or away from the center of the light-emitting areas to either reduce or increase the focusing power of the microlens. The microlenses and color filter elements in each pixel may also be shifted to account for the chief ray angle of the display.

Electronic device displays having microlenses

A system for providing continuous cooling to a storage rack, including a storage rack, including a first storage node and a second storage node; a first cooling loop including a first cooling distribution unit (CDU); a second cooling loop including a second cooling distribution unit (CDU); a first inlet switching valve coupled between the first storage node and each of the first and the second CDUs; a second inlet switching valve coupled between the second storage node and each of the first and the second CDUs; wherein, when the first cooling loop experiences a failure, a state of the first inlet switch and a state of the second inlet switch is adjusted to i) prevent the first CDU from providing cooling of the first storage node and the second storage node, ii) allow only the second CDU to provide cooling of the first storage node and the second storage node.

Providing continuous cooling to a storage rack

A system may have windows. The window may have first and second window layers and a layer of material such as guest-host liquid crystal material between the first and second window layers. Electrodes on the window layers may be used to apply electric fields to the guest-host liquid crystal material to adjust the light transmission properties of the window. To ensure that a desired gap between the first and second window layers is maintained, spacers may be formed between the first and second window layers. The spacers may include key-and-lock spacers that have interlocking portions located, respectively, on the first and second window layers. Spacers such as photoresist posts can be attached using adhesive. Hybrid arrangements may also be used in which key-and-lock spacer structures are attached using adhesive bonds.

Adjustable windows

An optical system is described. The optical system may include a sensor which may be in a mobile device. The optical system may use the same light source for imaging the display and for providing light to a sensor or sensor device. The optical system may be configured so that randomly polarized light will exit the device for viewing so that a user may view the display in any rotated orientation while wearing polarized eyewear. The optical system may further be configured to mitigate reflections in the mobile device from ambient light entering the system and from reflected and backscattered light from cross-contaminating the imaging light of the display.

Devices and systems for under display image sensor

A highly available and modular cooling distribution unit (CDU) includes a heat exchange module and a pair of redundant pump modules, all configured to occupy a designated rack space that is comparable to rack space required for a conventional 1&#xd7;CDU without redundancy. The heat exchange module may be fluidically coupled to one or more rack information handling resources via liquid coolant conduits, manifolds and accompanying valves, sensors, etc. In at least one embodiment, the heat exchange module includes a heat exchanger to dissipate heat from a liquid coolant and a fan assembly to move heated air in proximity to the heat exchanger. Each pump module is coupled to the heat exchange module and configured to circulate liquid coolant through a closed loop circuit that includes the heat exchanger, the liquid coolant conduits and manifolds, and information handling resources.
