Title:
REARVIEW MIRROR WITH DIMMING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/130181
Kind Code:
A1
Abstract:
A rearview mirror with a dimming function is disclosed, comprising : a transparent cover substrate (101) covering substantially the full screen of the rearview mirror, an absorptive polarization layer (107) disposed below the transparent cover substrate (101) with a substantially uniform size, wherein when non-polarized ambient light passes through the absorptive polarization layer (107), the layer absorbs light of a polarization parallel to its absorption axis while transmits light of a polarization perpendicular to its absorption axis, a liquid crystal light-controlling layer (108) disposed below the absorptive polarization layer (107) with a substantially uniform size, and a reflective polarization layer (102) disposed below the liquid crystal light-controlling layer (108) with a substantially uniform size, which reflects the light of a polarization parallel to its reflective axis while transmits the light of a polarization perpendicular to its reflective axis. The rearview mirror can automatically adjust reflective light, while improving the utilization of the display light.
