Although various wipers used in the rain have been developed as described above, slipping of the wiper becomes worse when an oil film adheres to the window glass surface or when the amount of rainfall is small. It moves while rubbing rather than wiping the window glass while making a squeak noise or abnormal noise, so it stimulates the driver's nerves or interferes with the sight,

Liquid crystal is formed on the surface of an automobile window glass capable of receiving a reflection image by a thin film formed by impregnating a transparent silicon or Teflon (polymer of tetrafluoroethylene C 2 F 4 ) or a plastic sheet with silicon or Teflon. The body is provided in a sandwich shape, and high-frequency current is intermittently applied to the liquid crystal body or the liquid crystal body is excited by magnetic lines of force, and the vibration caused by the excitation of the liquid crystal body causes the raindrops attached to the surface of the film to drop and be removed. It was done. Then, when the liquid crystal is cut off, a landscape shot by a camera such as a wide-angle lens or a video camera, which is provided above the window glass for automobiles and faces forward, is sent as an image signal through an optical transmission path such as an optical fiber to an optical demodulator. It is sent to a built-in optical computer and imaged on a window glass that has been specially processed so that it can be photographed or converted into an electronic image and reflected and received so that the driver can recognize the external scenery.

When it rains while driving an automobile, when the liquid crystal body is excited by intermittently energizing the liquid crystal body, vibration occurs due to the undulation of the liquid crystal body itself, and the film also resonates. The raindrops falling due to the vibration of the coating hit the coating, but due to the force and the vibration, the raindrops are scattered without adhering to the surface of the coating.
When the amount of rainfall is low, the number of intermittent energizations is reduced, and as the amount of rainfall increases, the number of intermittent energizations also increases.

Further, the liquid crystal body is not invisible due to the intermittent energization, and the driver's eyes are always able to see the scenery, which does not hinder driving. And when it is hard to see when the liquid crystal body is broken, the scenery in front of the car taken by the camera is sent to the optical computer through the optical transmission path and displayed on the back of the window glass in the same way as the driver sees it.
Drive while watching it. In addition, since infrared rays are used at night, it can be visualized with car lights, so driving can be performed in the same way as daytime.
