VEHICULAR INTERIOR REARVIEW MIRROR ASSEMBLY WITH VIDEO MIRROR DISPLAY AND VRLC STACK
A vehicular interior rearview mirror assembly includes a mounting structure and a mirror head pivotally mounted at the mounting structure via a pivot joint. The mirror head includes a mirror casing and a display and mirror assembly, which includes a frame portion, a video display screen at a front side of the frame portion, and a mirror reflective element at a front side of the video mirror display screen. The mirror reflective element includes a variable reflectivity liquid crystal (VRLC) stack of layers, which have a liquid crystal (LC) layer disposed between a rear glass substrate and a front glass substrate. The front and rear glass substrates are integrated in the VRLC stack of layers. With the mounting structure mounted at an interior portion of a vehicle, the video display screen is operable to display video images derived from video images provided by an ECU of the vehicle.
Interior rearview mirror assembly with driver monitoring system
A vehicular interior rearview mirror assembly includes a mirror head having an interior mirror reflective element. The mirror reflective element has a mirror transflector that transmits near-IR light incident thereon, transmits visible light incident thereon and reflects visible light incident thereon. The mirror assembly includes a camera disposed within the mirror head and viewing through the mirror transflector. The camera includes an imaging sensor having a quantum efficiency (QE) of at least 15% for near-infrared (near-IR) light having a wavelength of 940 nm. The mirror assembly further includes first, second and third near-IR illumination sources disposed within the mirror head and operable to emit near-IR light that passes through the mirror transflector. The near-IR illumination sources are at respective angles relative to a planar front surface of the mirror reflective element and, when powered, illuminate respective in-cabin regions for a driver monitoring function or an occupant detection function.

A MULTI-LAYER FILM AND DISPLAY SYSTEM
Embodiments of the present disclosure relate to a multi-layer film and display system. The multi-layer film and display system includes a birefringent film, wherein the birefringent film substantially reduces a visibility of a regular optical pattern generated on the multi-layer film and display system when an at least partially polarized light is incident on the multi-layer film and display system.
INTERIOR REARVIEW MIRROR ASSEMBLY WITH DRIVER MONITORING SYSTEM
A vehicular interior rearview mirror assembly includes a mirror head having an interior mirror reflective element. The mirror reflective element has a mirror transflector that transmits near-IR light incident thereon, transmits visible light incident thereon and reflects visible light incident thereon. The mirror assembly includes a camera disposed within the mirror head and viewing through the mirror transflector. The camera includes an imaging sensor having a quantum efficiency (QE) of at least 15% for near-infrared (near-IR) light having a wavelength of 940 nm. The mirror assembly further includes first, second and third near-IR illumination sources disposed within the mirror head and operable to emit near-IR light that passes through the mirror transflector. The near-IR illumination sources are at respective angles relative to a planar front surface of the mirror reflective element and, when powered, illuminate respective in-cabin regions for a driver monitoring function or an occupant detection function.

First, second and third near infrared illumination sources are disposed within the mirror head and operable to emit near infrared light that passes through the mirror transflector. The near infrared illumination sources are at respective locations at the mirror reflective element and, when powered, illuminate respective seat regions for a driver-monitoring function or an occupant-detection function.
VEHICULAR DRIVER MONITORING SYSTEM
A vehicular driver monitoring system includes an interior rearview mirror assembly that includes a mirror head accommodating a mirror reflective element. A megapixel camera is accommodated by the mirror head and includes a backside Illumination (BSI) imaging sensor having an at least 2.3 megapixel imaging array of photosensors. The BSI imaging sensor has a quantum efficiency of at least 22% for near-infrared light having a wavelength of 940 nm. A near-infrared illumination source is accommodated by the mirror head. The mirror reflective element and the megapixel camera and the near-infrared illumination source move in tandem with the mirror head when the mirror head is adjusted by a driver of a vehicle. The megapixel camera views at least the eyes of the driver of the vehicle. The near-infrared illumination source, when powered to emit near-infrared light, illuminates at least the eyes of the driver of the vehicle.
