LIQUID CRYSTAL DISPLAY DEVICE
A liquid crystal display device includes a liquid crystal cell including a first substrate, a second substrate disposed on a viewer side to the first substrate, and a liquid crystal layer provided between the first substrate and the second substrate, and a first linear polarizer disposed on a viewer side to the liquid crystal cell, and has a plurality of pixels. Each of the pixels includes a reflective region where display is performed in a reflection mode. The liquid crystal display device does not include a λ/4 plate between the first linear polarizer and the liquid crystal layer. An in-plane retardation of the liquid crystal layer in the reflective region is configured to vary from approximately zero to approximately λ/4 depending on a voltage applied to the liquid crystal layer.
DEVICE FOR DISPLAYING INFORMATION, IN PARTICULAR FOR A VEHICLE
The device for displaying information, in particular for a vehicle, is provided with a display unit having a plurality of pixels and having a front side forming the display surface for displaying information and a rear side facing away from the front side. Furthermore, the device comprises a backlighting unit for emitting backlight towards the rear side of the display unit for backlighting the same, and an adjustable transreflective layer between the backlighting unit and the display unit. The adjustable transreflective layer has an array of segments, each of which is controllable by means of an electric control signal to adjust the degree of transmission and/or reflection and is thus dimmable. The contrast of information shown on the display surface can be adjusted by dimming, as a result of controlling the segments, those pixels of the display unit which are arranged in alignment with the segment or segments concerned and are assigned to the same.
Liquid crystal displays with polarized infrared illumination
Systems and methods for IR readable transmissive and reflective displays are disclosed that do not suffer from a mirror-like appearance or undesirable dimming of the display due to sequential stacks of polarizers. The disclosed systems and methods use available IR LEDs in addition to, or in place of, visible light LEDs. An illuminator or integrator, which is a lightguide, is designed to maintain the polarization state of the light. The display can use a regular visible light, front polarizer and hence does not suffer from brightness reduction caused by an IR capable polarizer.

VEHICULAR VISION SYSTEM
A vehicular vision system includes a forward-viewing camera located behind and viewing through a vehicle windshield, a rearward-viewing camera located at a rear of the vehicle, and a common image processor operable for processing captured image data. A video display screen is located within the interior cabin of the vehicle viewable by a driver of the vehicle. The common image processor processes first image data captured by the forward-viewing camera to detect at least one vehicle present exterior the equipped vehicle. Responsive to the vehicle being shifted into a reverse gear and while the driver is executing a reversing maneuver, video images derived from image data captured by at least the rearward-viewing camera are displayed by the video display screen.
REARVIEW ASSEMBLY WITH PIEZO VIBRATION DAMPENING
A rearview assembly is disclosed. The rearview assembly comprises a reflective element and/or a display element. Further, the rearview assembly comprises an array of piezo-electric sensors. The array of piezo-electric sensors may be operable to sense a first vibration. Further, based, at least in part, on sensing the first vibration, the array of piezo-electric sensors may be operable to output a second vibration. In some embodiments, the second vibration may be operable to substantially dampen the first vibration. In other embodiments, the second vibration may be operable to provide haptic feedback to a user interfacing with a touch screen surface of the rearview assembly.
