Problems solved by technology

[0003] With the continuous improvement of customers' requirements for sun visors, traditional sun visors can no longer meet the needs of customers
Because although the traditional car sun visor can block the sun, it occupies most of the driver's field of vision. Its own opacity is not good for sight, and there will be many safety hazards when the vehicle is driving, especially when the sun is about to set in the evening because the position of the sun is relatively low. , the traditional car sun visor can't really block ultraviolet rays at all, it can only play a role in covering part of the light, and it doesn't fundamentally solve the problem of blocking ultraviolet rays without hindering normal driving

Embodiment 1

[0026] The preparation method of the liquid crystal sun visor is as follows:

[0027] 1) Set two pieces of ITO conductive glass parallel to each other and seal the boundary between the two pieces of conductive glass with sealing glue, and open a through hole with a diameter of 5cm at the boundary seal, connect the vacuum device to seal the two pieces The sealed area between the conductive glasses is evacuated, then filled with liquid crystal polymer material until the through hole is just blocked, and finally a polarizing film is pasted on the outside of the two pieces of ITO conductive glass to complete the preparation of the liquid crystal sun visor. Plus photosensitive control circuit;

[0028] 2) Install the metal signal pin on the LCD sun visor and connect it to the upper side of the ITO conductive glass. The left and right corners of the upper part of the LCD sun visor are made into oblique shapes, and the left and right corners of the lower part of the LCD sun visor are...

Embodiment 2

[0030] The preparation method of the liquid crystal sun visor is as follows:

[0031] 1) Set two pieces of ITO conductive glass parallel to each other and seal the boundary between the two pieces of conductive glass with UV glue, and open 3-4 through holes with a diameter of 10cm at the boundary seal, and connect the vacuum device Vacuum the sealed area between the two pieces of conductive glass, then fill in the solution-type liquid crystal polymer material until the through hole is just blocked, the filling rate is controlled at 20ml / min, and finally the two pieces of ITO conductive glass Paste a piece of polarizing film on the outside to complete the preparation of the liquid crystal sun visor, and add a photosensitive control circuit;

[0032] 2) Install the metal signal pin on the LCD sun visor and connect it to the upper side of the ITO conductive glass. The left and right corners of the upper part of the LCD sun visor are made into oblique shapes, and the left and right...

[0034] The preparation method of the liquid crystal sun visor is as follows:

[0035] 1) Set two pieces of ITO conductive glass parallel to each other and seal the boundary between the two pieces of conductive glass with UV glue, and open 3-4 through holes with a diameter of 8cm at the boundary seal, and connect the vacuum device Vacuum the sealed area between the two conductive glasses, then fill in the solution-type liquid crystal polymer material until the through hole is just blocked, the filling rate is controlled at 22ml / min, and the filling temperature is controlled at 55- At 60°C, a piece of metal polarizing film is pasted on the outside of the two ITO conductive glasses respectively to complete the preparation of the liquid crystal sun visor, plus the photosensitive control circuit;

[0036] 2) Install the metal signal pin on the LCD sun visor and connect it to the upper side of the ITO conductive glass. The left and right corners of the upper part of the LCD sun viso...

Abstract

The invention provides a preparation method of a liquid crystal sun shield. The preparation method comprises the steps that (A) two pieces of ITO conducting glass are arranged oppositely, and boundaries of the two pieces of glass are sealed; (B) after sealing is completed, the space between the two pieces of ITO conducting glass is subjected to vacuumizing and filled with liquid crystal high polymer materials; and (C) a polarizing film is attached to the outer side of each piece of ITO conducting glass, and a light sensation control circuit is added. The liquid crystal sun shield obtained through the preparation method is transparent and good in ultraviolet blocking effect, and more stray light can be filtered and reflected out; in addition, automatic adjustment can be conducted according to the light intensity, the constant light which is the most proper for eyes is kept all the time, the human eyes are protected against fatigue, a view field of a driver is prevented from being blocked, and the driving safety is improved.

Description

technical field [0001] The invention relates to the application field of automobile sun visors, in particular to a liquid crystal sun visor and its preparation method and application. Background technique [0002] As we all know, the sun visor of a car is a board installed above the driver to prevent the glare of the sun. It can be turned down when in use and can be turned up when not in use. In the prior art, it is mainly made of aluminum foil, non-woven fabrics, and plastic resins. Kind of sun visor. Aluminum foil is generally divided into ordinary "light board" type and pattern type, and the size is generally 60*130cm, which is suitable for most small cars. In hot weather, you can turn the aluminum foil outward to ensure the reflection of sunlight. It is best to choose a sunshade with a suction cup when purchasing a sunshade. Do not buy a "light board" type or a too cheap front sunshade, which is easy to fall off. [0003] With the continuous improvement of customers' r...
