Description

Rearview mirror with display function and manufacturing method thereof

Technical Field

The invention relates to a rearview mirror and a manufacturing method thereof, and in particular to a rearview mirror with a display function and a manufacturing method thereof.

Background technique

The streaming media application smart rearview mirror product changes the focal length of the camera lens to obtain a wider range of images, which can improve the "blind spot" problem of traditional rearview mirrors to a certain extent. The driver can monitor the entire rear view by looking at the rearview mirror, making it less likely for the driver to be distracted. However, the streaming media application smart rearview mirror has a display area as large as the mirror surface. If the touch sensing layer is attached to the display through an optical adhesive layer, not only will the overall thickness become thicker, but the weight will also become heavier.

That is, the annular shielding layer 220 is made of non-transparent non-conductive material as a shielding ring, and is directly integrated with the touch sensing layer 230 on the same transparent substrate. In this way, the rearview mirror 10a of the present embodiment can have a touch function in addition to the full-screen display function, and can effectively reduce the overall thickness and weight. When the driver uses the rearview mirror 10a, he can directly touch the operation, which has better sensitivity, is easy to operate, and is beautiful.

In summary, in the design of the rearview mirror with display function of the present invention, the annular shielding layer and the touch sensing layer in the rearview mirror structure layer are both arranged on the second transparent substrate, and the annular shielding layer and the touch sensing layer are electrically insulated. That is, the annular shielding layer uses a non-transparent non-conductive material as a shielding ring, and is directly integrated with the touch sensing layer on the same transparent substrate. In this way, the rearview mirror of the present invention can have a touch function in addition to the full-screen display function, and can effectively reduce the overall thickness and weight. In addition, the display structure layer of the rearview mirror of the present invention also integrates the display body layer and the semi-transmissive and semi-reflective layer on the first transparent substrate, which can effectively reduce the weight and thickness of the rearview mirror.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
