Electronic anti-dazzle lens and vehicle rearview mirror with electronic anti-dazzle lens

Abstract

The invention discloses an electronic anti-dazzle lens. The electronic anti-dazzle lens is suitable for being arranged on the light emitting side of a display screen and comprises a first base plate,a second base plate, an electrochromic material layer and a reflection anti-reflection layer which are arranged in a stacked mode; when the electronic anti-dazzle lens is used, the first base plate faces a user, and the second base plate is arranged on the light emitting side of the display screen; and the electrochromic material layer is arranged between the first base plate and the second base plate, the reflection anti-reflection layer is arranged on the side, deviating from the first base plate, of the electrochromic material layer, the reflection anti-reflection layer has a reflection material and a polarization material and can selectively transmit or reflect light according to the polarization direction of light rays of the display screen. and more light rays of the display screen can be allowed to pass through, so that the brightness utilization rate of the display screen is greatly increased, and the requirement for the brightness of the display screen is reduced while the appearance of a display picture is ensured. In addition, the invention further discloses a vehicle rearview mirror with the electronic anti-dazzle lens.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to an electronic anti-glare lens and a vehicle rearview mirror with the electronic anti-glare lens. Background technique [0002] In response to the improvement of market demand and technological innovation, more and more types of products need to use electronic anti-dazzle functions, such as interior rearview mirrors and exterior rearview mirrors. At the same time, in order to improve the perception, the interior rearview mirror gradually adopts electronic display images to give car owners a clearer and larger viewing experience. This requires that the interior rearview mirror needs to integrate physical reflection function, electronic anti-glare function and display function. Therefore, the interior rearview mirror needs to be equipped with electronic anti-glare lenses. [0003] A traditional electronic anti-glare lens usually at least includes a first substrate, an ...

AI Technical Summary

Problems solved by technology

For vehicle-mounted rearview mirrors, the regulations require that their reflectivity cannot be lower than 40%, and because the composition and structure of traditional electronic anti-glare lenses reduce the light loss of the display screen, their transmittance to the display screen light is usually not higher than 50%. %, therefore, after the light of the display screen passes through the electronic anti-glare lens, the final display brightness is less than half of the surface brightness of the display screen itself
