Description

Technical Field

[0001] The utility model relates to the technical field of vehicle rearview mirrors, in particular to a streaming media rearview mirror. Background Art

[0002] The streaming media rearview mirror is a vehicle electronic product that can transmit the rear image to the rearview mirror through the camera next to the high-mounted brake light at the rear of the vehicle.

[0003] Existing streaming media rearview mirrors generally combine reflection and transmission. A display module can switch between reflection and transmission at the same time. When the transmission function is selected, it can be used as a touch display module. When the reflection function is selected, the LCD can be turned off and it can be used as a reflector.

[0004] We found that due to the reflective layer designed on the upper surface of the LCD liquid crystal display module, this reflective layer has a great influence on the transmittance of the entire module, resulting in low brightness of the display module. It is necessary to increase the backlight brightness to increase the brightness of the display module, but this will cause problems such as high power consumption and severe heat generation of the module, which may affect the normal operation of the module and reduce its service life.

When it is necessary to switch the TN mirror assembly 4 surface and the LCD liquid crystal display module 5 surface, the driving motor 2 can be started, and the power output shaft of the driving motor 2 can be rotated, thereby driving the rotating shaft 3 to rotate, and the rotation of the rotating shaft 3 drives the shell 1 to rotate, so that the TN mirror assembly 4 surface and the LCD liquid crystal display module 5 surface can be interchanged, and the control circuit starts the switching function while the driving motor 2 rotates to realize the control of the LCD liquid crystal display module 5 or the TN mirror assembly 4.

[0028] See also Figure 2-3 In this embodiment, the TN mirror assembly 4 includes a cover plate 401, an upper polarizer 402, an EC display panel upper glass 403, an EC display mirror FPC 404, an EC display panel lower glass 405, a lower polarizer 406 and a mirror reflective lens 407; the cover plate 401 is connected to the housing 1, the EC display panel upper glass 403 is installed on one side of the upper polarizer 402, the EC display panel lower glass 405 is installed on the other side of the EC display panel upper glass 403, the lower polarizer 406 is installed on the other side of the EC display panel lower glass 405, and the mirror reflective lens 407 is installed on the other side of the lower polarizer 406; one side of the upper polarizer 402 is connected to the cover plate 401 through an adhesive 6, and the adhesive 6 is OCA glue or OCR glue, and one port of the EC display mirror FPC 404 is bound to the binding position of the EC display panel lower glass 405.

[0029] Specifically, the cover plate 401 is a Cover Lens, which has high surface hardness and super scratch resistance, and can extend the service life. When voltage is applied to the TN mirror assembly 4, the TN mirror assembly 4 is opaque. When the voltage is removed from the TN mirror assembly 4, the TN mirror assembly 4 is transparent, and can be switched according to usage requirements.

[0030] See also Figure 4-5In this embodiment, the LCD liquid crystal display module 5 includes a touch panel 501, an upper polarizer 502, a touch panel FPC 503, a display module FPC 504, a CF sheet 505, a TFT substrate glass 506, a lower polarizer 507 and a BLU backlight module 508; the touch panel 501 is connected to the housing 1, the upper polarizer 502 is installed on one side of the CF sheet 505, the TFT substrate glass 506 is installed on the other side of the CF sheet 505, the lower polarizer 507 is installed on the other side of the TFT substrate glass 506, and the BLU backlight module 508 is installed on the outer side of the lower polarizer 507; the other side of the upper polarizer 502 is connected to the touch panel 501 through an adhesive 7, and the adhesive 7 is OCA glue or OCR glue.

[0033] Specifically, the TN mirror assembly 4 and the LCD liquid crystal display module 5 are kept away from each other, thereby avoiding the effect of heat accumulation. At the same time, heat dissipation holes can be opened at the top or bottom of the housing 1 to facilitate the heat dissipation of the inner side of the TN mirror assembly 4 and the LCD liquid crystal display module 5, thereby extending the service life of both.
