Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and more particularly to a streaming media rearview mirror with an anti-glare function. Background Art

[0002] The streaming media rearview mirror system consists of a wide-angle camera installed at the rear of the car, a display screen integrated into the rearview mirror, and a controller. The wide-angle camera captures images from behind the car, and the controller processes and displays the information behind the car on the display screen, basically eliminating the blind spot behind the car and is not affected by interference from rear passengers and other objects.

[0003] In recent years, streaming media rearview mirrors have become a standard feature of high-tech cars due to their wide viewing angle, which can effectively reduce blind spots and enhance visibility at night and in bad weather. In addition, they can be used as driving recorders.

[0004] The streaming media rearview mirror is required to be used as both a streaming media and an ordinary rearview mirror. When the streaming media rearview mirror is used as an ordinary rearview mirror, it is required to have an anti-glare function to avoid dangerous situations caused by high beams when driving at night.

[0026] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first," "second," or "third" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0027] The utility model provides a streaming media rearview mirror with an anti-glare function, which includes a cover plate, a dimming LCD and a TFT module, wherein the dimming LCD is arranged below the cover plate, a fully transparent polarizer is arranged above the dimming LCD, and an RPM reflective film is arranged on the lower surface of the dimming LCD; the TFT module includes a lower polarizer, a lower substrate, an upper substrate and an upper polarizer stacked in sequence from bottom to top, and the light transmission axis of the upper polarizer is consistent with the light transmission axis of the RPM reflective film.

[0028] Since the transmission axis of the upper polarizer is consistent with the transmission axis of the RPM reflective film, the dimming LCD does not affect the TFT module display. When the dimming LCD is not powered on, the RPM reflective film has a high reflectivity and can be used as a mirror. When the dimming LCD is powered on, the mirror reflectivity of the cover is reduced to the minimum, and the streaming media rearview mirror has an anti-glare effect, so that the streaming media rearview mirror can be used as both a streaming media and an ordinary rearview mirror, and has an anti-glare function.

The dimming LCD2 is arranged below the cover plate 1, and a fully transparent polarizer 21 is arranged above the dimming LCD2. The lower surface of the dimming LCD2 is provided with an RPM reflective film 22; the TFT module 3 includes a lower polarizer 31, a lower substrate 32, an upper substrate 33 and an upper polarizer 34 stacked in sequence from bottom to top, and the light transmission axis of the upper polarizer 34 is consistent with the light transmission axis of the RPM reflective film 22. Since the transmission axis of the upper polarizer 34 is consistent with the transmission axis of the RPM reflective film 22, it is ensured that the dimming LCD2 does not affect the display of the TFT module 3. When the dimming LCD2 is not powered on, the RPM reflective film 22 has a high reflectivity and can be used as a mirror; when the dimming LCD2 is powered on, the mirror reflectivity of the cover plate 1 is reduced to a minimum, and the streaming media rearview mirror has an anti-glare effect, so that the streaming media rearview mirror can be used as both a streaming media and an ordinary rearview mirror, and has an anti-glare function.

[0031] See also Figure 2Furthermore, the cover plate 1 includes a visible area and a non-visible area. A chrome layer 11 is provided on the upper or lower surface of the cover plate 1 located in the non-visible area. The chrome plating outside the visible area of ​​the cover plate 1 allows the cover plate 1 to function as a standard rearview mirror when the TFT module 3 is not displaying. The chrome-plated area enhances the reflectivity of the glass cover plate 1, allowing it to function as a mirror while maintaining a close interface with the RPM film. When used as a standard rearview mirror, it becomes a large mirror.
