The photochromic material 3 in the scheme can be but is not limited to silver halide microcrystals such as silver bromide microcrystals and silver chloride microcrystals, can change color under the irradiation of sunlight or ultraviolet light, the higher the irradiation intensity of the sunlight or ultraviolet light is, the larger the color depth is, the enough light transmittance can be kept without influencing the rear-view function, and the photochromic material can be recovered to be in a transparent state without the irradiation of the sunlight or ultraviolet light; the photochromic material 3 in the scheme can also be a diarylethene-iridium compound, and can directly generate reversible photochromic shadow elimination for visible light.
In one embodiment, the first substrate 1 is a transparent substrate, and the second substrate 2 is a reflective substrate.
The light-induced anti-glare rearview mirror in this embodiment provides a rearview image for a driver in a manner that the second substrate 2 reflects light behind the vehicle.
In another embodiment, as shown in fig. 2, the first substrate 1 and the second substrate 2 are transparent substrates, and a mirror or a display screen 6 is disposed on a side of the second substrate 2 facing away from the first substrate 1.
The light-induced anti-glare rearview mirror in the embodiment provides a rear view image for a driver in a mode of reflecting light rays behind the automobile through the reflector, or provides the rear view image shot by the camera behind the automobile for the driver in a mode of displaying the image behind the automobile through the display screen 6.
The display screen 6 is an LCD screen or an OLED screen.
In yet another embodiment, as shown in fig. 5 and 6, the first substrate 1 is a transparent substrate, and the second substrate 2 is an upper substrate 64 of the display screen 6.
The light-induced anti-glare rearview mirror in the embodiment provides a driver with a rear view image shot by the rear camera through the mode that the display screen 6 displays the rear image of the automobile.
