Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of in-vehicle streaming media rearview mirrors, and particularly relates to a structure for improving the black shadow of an LC anti-glare mirror. Background Technique
[0002] The in-vehicle streaming media rearview mirror is a new type of automotive rearview mirror technology. Its working principle is to capture the scene behind the vehicle in real time through a camera behind the vehicle, and then transmit the image data to the display screen inside the vehicle to present a clear, wide and real-time rear road condition for the driver.
[0003] When the in-vehicle streaming media rearview mirror is turned on, it can be used as a streaming media. After the screen is turned off, it can also be used as an ordinary rearview mirror. It mainly uses the RPM film to switch between the display mode and the ordinary physical mirror mode.
[0004] For current streaming media rearview mirrors, the LC mirror anti-glare solution is often adopted. However, when LC is compatible with anti-glare and high transmittance, there will be an unavoidable black shadow around it. The black shadow is mainly caused by the silk screen layer of the glass cover plate forming a reflection on the bottom RPM film. The thickness of the upper and lower glasses of the commercially produced LC is 0.7 mm each, resulting in an overly thick overall thickness and obvious black shadows, which significantly affects the effect of the integrated silver in the screen-off state. Therefore, those skilled in the art have provided a structure for improving the black shadow of an LC anti-glare mirror to solve the problems raised in the above background technique. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0027] Please refer to the attached Figures 1 to 3 As shown in the figure, a structure for improving the black shadow of an LC anti-glare mirror in an embodiment of the present invention includes a housing 1. A display module 2 is fixed inside the housing 1. A glass cover plate 3 is arranged at the outer end of the display module 2. A cover plate silk printing layer 10 is arranged at the periphery of the rear end face of the glass cover plate 3. An anti-glare component is laminated between the glass cover plate 3 and the display module 2.
[0028] The anti-glare component includes a lower polarizer 4 and an upper polarizer 8. A lower glass 6 and an upper glass 7 are laminated between the lower polarizer 4 and the upper polarizer 8. The thicknesses of both the lower glass 6 and the upper glass 7 are 0.25 mm. The lower glass 6 and the upper glass 7 both adopt a thinning process to reduce the thickness. Compared with the LC upper and lower glasses with a thickness of 0.7 mm in mass production on the market, the overall thickness is reduced by 0.9 mm, thereby reducing the degree of light refraction and the width of the black shadow, and effectively improving the black shadow.
[0029] In addition, the double-layer polarizer structure of the lower polarizer 4 and the upper polarizer 8 can more effectively reduce the reflected light on the surface of the glass cover plate 3, reduce glare interference, provide a clearer and interference-free image, further enhance the contrast of the image, and make the display content more distinct.

The glass cover plate 3 and the upper polarizer 8 are connected through the optical transparent adhesive layer 9. The thickness of the optical transparent adhesive layer 9 is 0.25 mm. The optical transparent adhesive has excellent adhesiveness, which can ensure stable connection, and at the same time has high transparency, so as to maintain good light transmittance between optical elements and does not affect the clarity and color accuracy of the image.
[0031] The anti-glare component further includes an RPM film 5. The RPM film 5 is attached between the lower polarizer 4 and the lower glass 6. The thickness of the RPM film 5 is 0.073 mm.
[0032] The thicknesses of both the upper polarizer 8 and the lower polarizer 4 are 0.21 mm.

The ball head 13 is rotatably connected to the housing 1. A lens ring 11 is fixedly connected to the outer end of the housing 1. The lens ring 11 is wrapped around the periphery of the glass cover plate 3. The housing 1 is used to protect the internal display module 2 and the anti-glare component. The provided installation base 12 facilitates the installation and fixation of the housing 1. Moreover, the installation base 12 is connected to the housing 1 through the ball head 13 and can rotate, facilitating the adjustment of the rearview mirror angle.
