Rearview mirror with dimming function

A rearview mirror with a dimming function, comprising:

• a transparent cover substrate substantially covering the full screen of the rearview mirror;
• an absorptive polarization layer positioned below the transparent cover substrate with a substantially uniform size as the transparent cover substrate, wherein the absorptive polarization layer absorbs light of a polarization parallel to the absorption axis of the absorptive polarization while transmits light of a polarization perpendicular to the absorption axis of the absorptive polarization;
• a liquid crystal light-controlling layer positioned below the absorptive polarization layer with a substantially uniform size as the absorptive polarization layer;
• a reflective polarization layer positioned below the liquid crystal light-controlling layer with a substantially uniform size as the liquid crystal light-controlling layer, wherein the reflective polarization layer reflects light of a polarization parallel to the reflection axis of the reflective polarization layer while transmits light of a polarization perpendicular to the reflection axis of the reflective polarization layer;
• a display layer including at least one display region, wherein the at least one display region is disposed under at least a portion of the reflective polarization layer, and wherein the at least one display region is configured to emit polarized display light of a polarization perpendicular to the reflection axis of the reflective polarization layer,
• wherein the absorption axis of the absorptive polarization layer is perpendicular to the reflection axis of the reflective polarization layer;
• and
• a touch layer,
• wherein the touch layer defines at least one touch region with a substantially same size and position as the at least one display region between the transparent cover substrate and the absorptive polarization layer or between the reflective polarization layer and the at least one display region.
