[0022] Reference Numerals:
[0023] EC liquid layer 10, seal 11, transparent substrate assembly 20, upper glass sheet 21, lower glass sheet 22, conductive layer assembly 30, first conductive layer 31, second conductive layer 32, sealant 40. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] To facilitate understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.
[0025] An embodiment of the present application provides an automotive rearview mirror display component. Please refer to Figure 1, including: an EC liquid layer 10, a seal 11, a transparent substrate assembly 20, and a conductive layer assembly 30. The conductive layer assembly 30 is disposed on opposite sides of the transparent substrate assembly 20. The EC liquid layer 10 is disposed between the conductive layer assemblies 30. The seal 11 seals and encloses one side of the EC liquid layer 10, the conductive layer assembly 30, and the transparent substrate assembly 20. When the conductive layer assembly 30 is energized, it can cause the EC liquid layer 10 to change color to gradually present an image.
[0026] In this application, by providing the seal 11 to wrap the EC liquid layer 10, the transparent substrate assembly 20, and the conductive layer assembly 30, the interference of external water vapor to the EC liquid layer 10 is isolated, improving the reliability of the product and the user experience.
[0027] It should be noted that: the seal 11 is a fluororubber seal ring, which has excellent high-temperature resistance, oil resistance, chemical corrosion resistance, and waterproof performance. The fluororubber seal ring can work at a temperature of up to 250 °C and still maintain good sealing performance in high-humidity and high-temperature environments. Therefore, the fluororubber seal ring can isolate the water vapor outside the assembly and ensure the function of the assembly.
[0028] Furthermore, the conductive layer assembly 30 includes a first conductive layer 31 and a second conductive layer 32. The first conductive layer 31 is disposed above the EC liquid layer 10, and the second conductive layer 32 is disposed below the EC liquid layer 10 to connect to an external power source for energization. The positive pole of the external power source is electrically connected to the first conductive layer 31, and the negative pole is connected to the second conductive layer 32 to cause the EC liquid layer 10 to present a pattern.
[0029] In one of the embodiments, the first conductive layer 31 and the second conductive layer are indium tin oxide sheets or silver foil sheets. Both the indium tin oxide sheets and the silver foil sheets have good electrical conductivity and can save electrical energy. Among them, the preferred conductive effect is that the thickness range of indium tin oxide is 200 - 300 nm, and the thickness range of the silver foil sheet is 100 - 200 nm.
[0030] Furthermore, please refer to Figure 1 , the transparent substrate assembly 20 includes an upper glass sheet 21 and a lower glass sheet 22. The upper glass sheet 21 is disposed above the first conductive layer 31, and the lower glass sheet 22 is disposed below the second conductive layer 32 to facilitate the smooth filling of the EC liquid layer 10 between the conductive layer assemblies 30. Among them, the thickness range of the upper glass sheet 21 and the lower glass sheet 22 is 0.4 - 1.8 mm.
[0031] Please refer to Figure 1, the embodiment of the present application further includes a sealant 40, the sealant 40 includes a first sealant and a second sealant, the EC liquid layer 10 includes a first side and a second side, the first sealant is disposed on the first side of the EC liquid layer 10, the second sealant is disposed on the second side of the EC liquid layer 10. After the first sealant is disposed on the first side of the EC liquid layer 10, the EC liquid layer 10 fills between the first conductive layer 31 and the second conductive layer 32, and flows to the first sealant at the bottom. After filling the sufficient EC liquid layer 10, the second sealant is connected to the second side of the EC liquid layer 10, so as to smoothly fill the EC liquid layer 10 into the space inside the conductive layer assembly 30.
[0032] In addition, the thickness of the sealant 40 is the same as the thickness of the filled EC liquid layer 10, so that the EC liquid layer 10 fills the space between the conductive layer assembly 30 and the sealant 40 to prevent liquid leakage. Among them, the thickness range of the sealant 40 is 80-100um. Among them, the thickness of the EC liquid layer 10 and the sealant 40 with better display effect is 88um.
[0033] The embodiment of the present application further includes an automotive rearview mirror frame, and the seal 11 is connected to the automotive rearview mirror frame, which can shock-absorb the transparent substrate assembly 20 in the seal 11 to protect the upper glass sheet 21 and the lower glass sheet 22.
[0034] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
