Partial block response composite spliced liquid crystal dimming film car window

Abstract

The invention relates to a local block response composite spliced liquid crystal dimming film car window, the car window comprises a window body and a dimming mechanism arranged on the window body in a liftable manner, and the car window is characterized in that the dimming mechanism comprises glass arranged on the window body; the liquid crystal dimming film is arranged in the glass, and the liquid crystal dimming film is made of a flexible material; the functional layer is arranged between the liquid crystal dimming film and the glass; the liquid crystal light adjusting film comprises a first light adjusting film and a second light adjusting film, and the first light adjusting film and the second light adjusting film are spliced. The functional layer comprises a light blocking area, the area where the first light adjusting film and the second light adjusting film are spliced is a connecting area, and the light blocking area corresponds to the connecting area in position and size. The situation that when the dimming area of the liquid crystal dimming film becomes dark, strong light penetrates through the connecting area of the liquid crystal dimming film, the sight of a driver is affected, and potential safety hazards are caused is avoided.

Description

technical field [0001] The invention relates to the technical field of dimming vehicle window manufacture, in particular to a composite splicing liquid crystal dimming film vehicle window with partial block response. Background technique [0002] The window is an important part of the entire body, designed to meet the needs of lighting, ventilation and the vision of the driver and passengers. Generally, the light transmittance of the window is constant, but in summer, due to the strong sunlight, There is a situation of being dazzled by the sun. Once the eyes are hard to open due to the sunlight, the driver is prone to accidents during the driving of the car. At present, there is also a liquid crystal dimming film in the glass, by changing the light transmittance of the dimming film, to play a similar effect as a blind, when the light is strong, the dimming film becomes dark, and when the light is weak, the dimming film become transparent. However, limited by the existing t...

AI Technical Summary

Problems solved by technology

However, limited by the existing technology, there are requirements for the size of the dimming film in the production process, that is, in large-scale application scenarios, it is necessary to organically combine several liquid crystal dimming films to meet the application requirements

Normally, the epoxy resin around the liquid crystal dimming film will be hidden in the frame of the window. However, the epoxy resin between the two spliced ​​liquid crystal dimming films cannot be hidden by the window and will form on the glass. Obvious connection area, the connection area does not have dimming function, when the vehicle encounters strong light, the dimming area senses the strong light and adjusts its own light transmittance, making the glass in the dimming area darker, while the connecting area does not have dimming function function, and epoxy resin is a transparent material, when strong light passes through the connection area, the connection area becomes extremely bright, and the extremely bright connection area forms a strong contrast with the darkened dimming area, if the angle of the strong light hits driver's eyes, there is a major safety hazard

At the same time, the user dims the LCD dimming film of the car window, and there is also a need for privacy to prevent pedestrians outside the car from seeing the scene inside the car. However, the light transmission of the connection area makes the privacy unable to meet the demand
