Embodiment
[0031] The method for making an automobile anti-glare rearview mirror by using dye liquid crystals comprises the following process steps:
[0032] 1) Patterns are formed on the ITO layers of the upper and lower glass through exposure and etching on the upper and lower ITO glass respectively;
[0033] 2) Coating alignment liquid SE3310 on the lower ITO layer 13 on the upper ITO glass 1 and the lower ITO layer 5 on the lower ITO glass 3 with a thickness of 800 angstroms and heating to 270 o C, form a vertical alignment film after curing, and then use a rubbing cloth to rub on the alignment film to form a 45-degree groove;
[0034] 3) Around the lower ITO glass, screen-print the upper frame glue (model XN-5A-C); on the edge of the upper ITO glass, screen-print conductive material (model RL-1507E), each with a thickness of 10 microns, and spray on the ITO glass 8.5um diameter pads (model SP-2085), density 130 / mm 2 , and then bond the upper and lower pieces of ITO glass together,...

The invention discloses an automobile automatic anti-dazzling rearview mirror manufactured by using a dye liquid crystal light valve and a manufacturing method thereof. The rearview mirror structurally comprises a dye liquid crystal light valve lens of the automobile automatic anti-dazzling rearview mirror, a circuit board with a rear light sensitive device, a power indicator lamp, a shell, a fixed bracket and a circuit for automatically adjusting and controlling the reflectivity of the rearview mirror, wherein the fixed bracket, the shell, the circuit board with the rear light sensitive device, and the dye liquid crystal light valve lens of the automobile automatic anti-dazzling rearview mirror constitute an automobile sun shield, the circuit board with the rear light sensitive device and the circuit for automatically adjusting and controlling the reflectivity of the rearview mirror are arranged in the shell, the dye liquid crystal light valve lens of the automobile automatic anti-dazzling rearview mirror is clamped in an installing seam of the shell, a drive interface is connected with the circuit board with the rear light sensitive device, and the power indicator lamp is arranged on the shell. The rearview mirror and manufacturing method thereof disclosed by the invention have the advantages that the dye liquid crystal light valve is used as a transmission device, and the reflectivity is automatically adjusted by using the light sensitive device, so that the stimulation of back light to the eyes of a driver is reduced, the manual operation intensity of the driver is lowered, and the driving safety is improved.
Description
technical field [0001] The invention relates to an automatic anti-glare rearview mirror for automobiles made by using a dye liquid crystal light valve and a manufacturing method thereof. The dye liquid crystal light valve is used as a light valve to automatically adjust the reflectivity of the automobile rearview mirror, and belongs to the technical field of automobile electronic accessories. Background technique [0002] Although the rearview mirror is an auxiliary tool in the accessories of the car, the probability of application is very high. It is needed when the car is reversing or when the car is turning. Its function is to observe the situation behind the car. However, if strong light shines on the rearview mirror due to certain circumstances, it will cause the driver's visual vertigo, seriously affect the driver's driving, and may cause traffic accidents. After research, vertigo will cause the driver's reaction to be delayed by 1.4 seconds compared with normal cond...
