摘要： A privacy glazing structure may include an electrically controllable optically active material that provides controlled transition between a privacy or scattering state and a visible or transmittance state. To make electrical connections with electrode layers that control the optically active material, the privacy glazing structure may include electrode engagement regions. In some examples, the electrode engagement regions are formed as notches in peripheral edges of opposed panes bounding the optically active material. The notches may or may not overlap to provide a through conduit in the region of overlap for wiring. In either case, the notches may allow the remainder of the structure to have a flush edge surface for ease of downstream processing.

摘要： A control system for independent alternating-input (“IAI”) devices includes multiple IAI devices and an analog switch component. The control system may also include a bus-generating component. The analog switch component includes multiple switches configured to connect of disconnect input connection points of the analog switch component and voltage input points of the IAI devices. The analog switch component opens or closes switches, responsive to a digital control signal, to provide voltage signals to the voltage input points of the IAI devices. In some cases, the IAI devices activate or deactivate based on the provided voltage signals. In some cases, the bus-generating component provides a first voltage signal to a first voltage input point of an IAI device, and the analog switch component controls the switches to provide a second voltage signal to a second voltage input point of the IAI device.

摘要： The present invention provides a liquid crystal display panel and a display device. The liquid crystal display panel includes an array substrate, a counter substrate, and a liquid crystal layer. The array substrate includes a first alignment layer and a second alignment layer. The second alignment layer is arranged on one side of the first alignment layer away from the liquid crystal layer. A dielectric constant of the first alignment layer is less than a dielectric constant of liquid crystal molecules, and a dielectric constant of the second alignment layer is greater than the dielectric constant of the liquid crystal molecules. Accordingly, the present invention not only ensures high light transmittance, but also prevents residual images.

摘要： A trim element having a first aspect layer, a lighting device emitting light to the first aspect layer, and a first obturation layer extending between the lighting device and the first aspect layer. The first obturation layer includes at least two first optical obturation areas, configurable between an open position, in which a first optical obturation area lets light pass through, and a closed position, in which a first optical obturation area prevents the passage of light. The trim element includes a second aspect layer and a second obturation layer having at least two second optical obturation areas that are configurable between an open position and a closed position.

摘要： A display comprises a polarised output spatial light modulator, switchable liquid crystal retarder, absorbing polarizer and touch panel electrodes. The switchable liquid crystal layer is stabilised by a cured reactive mesogen material during application of an applied voltage. Light scatter in privacy mode is reduced and visual security level enhanced. Visibility of disclinations during application of applied pressure, for example from a finger on a touch screen is minimised.

摘要： A device includes a polymer stabilized blue phase liquid crystal (“PS-BPLC”) layer. The device also includes an alignment structure coupled with the PS-BPLC layer. LC molecules disposed in contact with the alignment structure are configured to have a spatially varying in-plane orientation pattern that is at least partially defined by the alignment structure. The PS-BPLC layer is configured to forwardly deflect a polarized light having a predetermined handedness, and transmit a polarized light having a handedness that is orthogonal to the predetermined handedness.
