A smart glass display includes a first glass layer, a second glass layer, a display layer, an auto-shading layer and a control module. The display layer is disposed between the first glass layer and the second glass layer and includes an array of light emitting diodes and at least one ambient light sensor. The at least one ambient light sensor is configured to detect a level of ambient light at the display layer. The auto-shading layer includes suspended particle devices each of which configured to selectively provide different levels of transparency. The control module is configured to, based on an output of the at least one ambient light sensor, adjust a transparency level of at least a portion of the auto-shading layer.

A window includes: a window frame having an opening defined therein through which an outdoor space and an indoor space communicate with each other; a pair of sashes slidably disposed in the window frame and that slide along an opening direction and a closing direction opposite to the opening direction; variable transmittance windowpanes configured to be fitted in the sashes to open and close the opening together with the sashes depending on sliding of the sashes; the variable transmittance windowpanes having a transmittance variable by electrical connection; first conductive members disposed on the sashes and electrically connected with the variable transmittance windowpanes to supply electric power to the variable transmittance windowpanes; and a second conductive member electrically connected with the first conductive members to supply the electric power to the first conductive members from outside the window frame.

A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.

Light-emitting component includes a light source and a dimming element arranged downstream of the light source in a radiation direction. The dimming element includes a dimming layer. The light source includes at least one emitter which is configured to emit light. A brightness of a light emitted by the light-emitting component is adjustable. The brightness is partially adjustable by way of a pulse width modulated and/or amplitude modulated operating signal for the emitter, and the brightness is partially adjustable by way of partial absorption and/or reflection of the light emitted by the emitter in the dimming element. A dimming capability of the dimming layer increases along an extension direction transverse to the radiation direction. The dimming layer is displaceable along the extension direction relative to the light source. A degree of absorption and/or reflection of light emitted by the emitter is variably adjustable.

The demand for automotive glazings, on which the intensity of the light transmitted can be controlled by the user, has been increasing as the public becomes more aware of the technology. The most common methods employed to make such glazings utilize Suspended Particle Devices (SPD) and Polymer Dispersed Liquid Crystal (PDLC) films. With both, the light transmission of the glazing changes in response to an alternating current electrical field. A problem with this technology is that is that the voltage required is far higher than that of the typical automotive electrical system. The disclosure provides a touch potential safe, small, lightweight and inexpensive means for controlling the light transmission of multiple glazing circuits by combining a single flyback voltage converter with multiple variable amplitude sinewave generators all coordinated by a micro-controller.
