Problems solved by technology

However, in the daytime when the light is too bright and the incident light is strong, or when the incident light irradiated by the headlights of the rear driver corresponds to the rearview mirror, a glare phenomenon will occur, so that the driver cannot see the image on the reflector group. It is clear, so this situation is related to the high reflectivity of the mirror group and it is easy to form a state. If the incident light is strong, the transmittance can be reduced, and this situation will be alleviated. Therefore, how to reduce the aftermath The anti-glare condition of the mirror is related to the reflection of the mirror group, which is worthy of further innovation and research and development

Abstract

The invention provides a vehicle display mirror and a manufacturing method of the vehicle display mirror. The vehicle display mirror comprises a reflection type polarized light unit and an image display unit. The reflection type polarized light unit at least comprises a multi-layer-film reflective sheet, wherein the multi-layer-film reflecting sheet is formed by overlapping a plurality layers of high molecular optical films; at least one layer of the plurality layers of high molecular optical films is a birefraction material layer, wherein the birefraction material layer meets the condition that NX is not equal to NY, and NY is not equal to NZ; the NX is the refractive index of light in the X direction; the NY is the refractive index of light in the Y direction; and the NZ is the refractive index of light in the Z direction. The image display unit comprises at least one display screen, wherein the multi-layer-film reflective sheet is arranged on the display screen.

Description

technical field [0001] The invention relates to a display mirror for a vehicle and a manufacturing method thereof, in particular to a display mirror for a vehicle that can be used as a rearview mirror of a vehicle and a manufacturing method thereof. Background technique [0002] In the past, the mirror group of the traditional rearview mirror reflected the rear image through metal coating or multi-layer film reflection layer, so that the driver could monitor the safety of driving around at any time. However, in the daytime when the light is too bright and the incident light is strong, or when the incident light irradiated by the headlights of the rear driver corresponds to the rearview mirror, a glare phenomenon will occur, so that the driver cannot see the image on the reflector group. It is clear, so this situation is related to the high reflectivity of the mirror group and it is easy to form a state. If the incident light is strong, the transmittance can be reduced, and t...
