The security system (1) has a liquid crystal film (3) with an adjustable transparency, wherein the liquid crystal film (3) is arranged on the transparent pane device (2) and/or at a distance to the transparent pane device (2). A sensor unit (4, 5, 7A to 7E) is designed to emit a sensor signal. The sensor unit (4, 5, 7A to 7E) is arranged on the transparent pane device (2). In addition, a control device (8) is provided for adjusting the transparency of the liquid crystal film (3) in accordance with the sensor signal.

A system for improving safety while providing privacy for a vehicle. The system includes a display screen located within the vehicle, configured to alternate between a displaying state and a non-displaying state. The system includes a window configured to alternate between an opaque state and a transparent state. The system includes an electronic control unit (ECU) configured to determine whether the display screen is powered on. The ECU is configured to alternate the display screen between the displaying state and the non-displaying state at a predetermined frequency when the display screen is powered on. The ECU is configured to alternate the window between the opaque state and the transparent state at the predetermined frequency, the display screen being in the displaying state when the window is in the opaque state and the display screen being in the non-displaying state when the window is in the transparent state.

According to one embodiment, a display device includes a display panel including a display surface, which displays an image by selectively reflecting light entering the display surface, and an illuminating device including an optical modulator provided on a display surface side of the display panel and including a plurality of portions in a major surface thereof and a light source provided on a side surface of the optical modulator, and the illuminating device illuminates the display panel at a predetermined brightness specific for each respective portion with the light entering the optical modulator from the light source.

A combination of a container in which foodstuffs are to be prepared and stored, and an electrically powered food-processing appliance, wherein at least a portion of the container includes material responsive to electrical energy applied thereto to vary the transmission of light therethrough. The appliance is configured for selectively applying electrical energy to the material, whereby at least said portion of said container is selectively rendered more transmissive to light.

In a display device, an image display panel updates an image in a frame cycle including an image scanning period and a vertical blanking period, a light modulation layer is disposed at a back of the panel and switched to a scattering or transmission state depending on an electric field applied, a light source emits light which enters the light modulation layer from its side and travels therethrough, electrodes are formed according to divided areas of the light modulation layer arranged in a direction of the light and apply the electric field to the light modulation layer, and a controller drives the electrodes in synchronization with image scanning to switch the divided areas to the scattering state in order during the image scanning period, and drives the electrodes according to distances from the side to control the scattering state on the individual divided areas during the vertical blanking period.

A 2D/3D switchable display device is disclosed. Said 2D/3D switchable display device comprises: a backlight panel, a first liquid crystal display panel at a light emergent side of the backlight panel, and a black-and-white second liquid crystal display panel at a light emergent side of the first liquid crystal display panel; wherein during 3D display, the second liquid crystal display panel is fully light-transmissive; during 2D display, liquid crystal molecules in the second liquid crystal display panel are arranged irregularly so as to scatter light emitted from the first liquid crystal display panel.

An adaptive backlight module and a method and system for producing an adaptive backlight module are described herein. The method of producing an adaptive backlight module includes: forming at least one enhancement film on a first substrate, forming a polarizer on the enhancement film, forming a diffuser by forming a liquid crystal layer between a first electrode on the first substrate and a second electrode on a second substrate, and connecting the diffuser to a light source.

A display device is disclosed. The display device includes: a plurality of side portions, each side portion comprising a transparent display panel; and a light source disposed at a lateral side of the transparent display panel. The display device can be used to display pictures towards a plurality of directions, and can be used to exhibit an article.

The present disclosure includes systems, methods, computer readable media, and devices that can generate and present a digital overlay over a view of a tangible object within a display case. In particular, the systems and methods described herein can synchronize a switchable diffuser element with a display screen and one or more light sources to alternate between a scatter state and a transparent state based on a display rate. In particular, the disclosed systems and methods can alternate the display screen between an emissive state (for displaying an emitted digital image) and an attenuating state (for displaying a transparency mask image). By synchronously toggling the display screen and the diffuser element between states, the disclosed systems can present a digital overlay superimposed over a view the inside of the display case.
