Description

Technical Field

[0001] The utility model relates to the technical field of rearview mirrors, in particular to an integrated rearview mirror module structure. Background Art

[0002] The purpose of a car rearview mirror is to expand the driver's field of vision, so as to help the driver understand the surrounding environment of the car and improve driving safety. On the other hand, however, the surrounding adverse problems can also affect the driver through the rearview mirror, and this influence sometimes poses a great safety hazard. A typical example is that when driving at night, the high beam of the car behind will strongly stimulate the driver's eyes through the rearview mirror, which will seriously interfere with the driver's normal driving. Considering that the rearview mirror with a touch display can partially offset this glare interference when the display is turned on (but due to the inherent high reflectivity of the rearview mirror, this glare pollution still poses a great safety hazard).
