The present invention provides a display panel and a display module. The display panel includes a first substrate, a first electrode layer, a light control layer, a second electrode layer, and a second substrate. The light control layer includes a first liquid crystal and light blocking layers. When no voltage is applied to the light control layer, the first liquid crystal is configured as an atomized liquid crystal for scattering light. When a voltage is applied to the light control layer, the first liquid crystal is configured as a transparent liquid crystal, thereby effectively improving an anti-peep performance of the display panel.

Provided is a liquid crystal display device capable of switching between a transparent state and a scattering state, reducing or preventing a decrease in transmittance in the transparent state, and reducing or preventing a decrease in luminance in the panel central portion in the scattering state. The liquid crystal display device includes, sequentially from its viewing surface side toward its back surface side: a first liquid crystal panel; a light source; and a second liquid crystal panel, the first liquid crystal panel including a polymer dispersed liquid crystal containing a polymer network and liquid crystal components, the light source being configured to irradiate a back surface side main surface of the first liquid crystal panel with light from an oblique direction.

The liquid crystal display device includes an edge backlight including a transparent light guide plate and light-emitting elements of multiple colors that are disposed such that the light-emitting elements of multiple colors are adjacent to each other, a dimming liquid crystal layer that is disposed such that the dimming liquid crystal layer overlaps at least an end portion of the transparent light guide plate that faces the light-emitting elements of multiple colors in a plan view and that has a degree of haze that increases or decreases by applying a voltage, and a transmissive liquid crystal display panel that includes pixels. With the backlight on, the dimming liquid crystal layer is in a diffusion state, and the liquid crystal display panel performs the color display. With the backlight off, the dimming liquid crystal layer is in a transmission state, and the liquid crystal display panel performs the transparent display.

A liquid crystal element includes a substrate, a diffractive optical element layer, and a liquid crystal material. The diffractive optical element layer has an uneven surface. The liquid crystal material is between the substrate and the uneven surface of the diffractive optical element layer. The liquid crystal material is disposed contiguously with the uneven surface of the diffractive optical element layer.

A vehicle can include a window including an interior side and an exterior side. The vehicle can include a camera located on an exterior of the vehicle. The camera can be operatively positioned to capture visual data of a blind spot of an external environment of the vehicle. The vehicle can include a dual-sided transparent display forming at least a portion of the window. The vehicle can include a processor operatively connected to the camera and the dual-sided transparent display. The processor can be configured to selectively cause the dual-sided transparent display to display exterior visual information on the exterior side. The processor can be configured to selectively cause the dual-sided transparent to display interior visual information on the interior side. The interior visual information can include the visual data of the blind spot of the vehicle.

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.

A backlight module and a liquid crystal display device are provided. The backlight module includes a first optical element which can switch between a transparent state and a scattering state, first light sources, and a light-shielding layer disposed on a light path of light emitted from the first light sources to a liquid crystal display panel. The light-shielding layer includes a plurality of gratings arranged at intervals, each of the gratings is made of a light-shielding material, and one light transmission gap is formed between any two adjacent gratings, thereby improving uniformity of backlight.

The liquid crystal display device includes an edge backlight including a transparent light guide plate and light-emitting elements of multiple colors that are disposed such that the light-emitting elements of multiple colors are adjacent to each other, a dimming liquid crystal layer that is disposed such that the dimming liquid crystal layer overlaps at least an end portion of the transparent light guide plate that faces the light-emitting elements of multiple colors in a plan view and that has a degree of haze that increases or decreases by applying a voltage, and a transmissive liquid crystal display panel that includes pixels. With the backlight on, the dimming liquid crystal layer is in a diffusion state, and the liquid crystal display panel performs the color display. With the backlight off, the dimming liquid crystal layer is in a transmission state, and the liquid crystal display panel performs the transparent display.

A liquid crystal display device and an electronic equipment are provided. The liquid crystal display device includes a liquid crystal display panel and an adjustable diffusion sheet configured to improve a light transmissive rate of a light transmissive region. The adjustable diffusion sheet includes a first sub-section corresponding to the position of the light transmissive region. When the light transmissive region is in a transparent state, the first sub-section is in a transparent state. When the light transmissive region is in a display state, the first sub-section is in a fog state.

A light modulation element that can vary between a bright transparent mode and a dark scattering mode is provided. The light modulation element has a first light modulation layer and a second light modulation layer comprising nematic liquid crystals and a dichroic dye in a scattering mode when a voltage is applied. The first light modulation layer and the second light modulation layer are disposed to overlap each other. The light modulation element has an improved contrast ratio and haze-variable characteristics, without precipitation of dichroic dyes and an increase in power consumption.
