Dimming device, use method, production method, car window, vehicle-mounted rearview mirror and car

Abstract

The invention discloses a dimming device. The dimming device comprises a photosensitive layer, a dimming layer, a transmittance-variable material layer and a controller, wherein the photosensitive layer comprises multiple photosensitive structures which generate electric signals according to sensed light intensity; the dimming layer comprises multiple dimming structures, and the multiple dimming structures and the multiple photosensitive structures correspond in pairs in the projection relationship; the transmittance-variable material layer comprises multiple material layers corresponding to the dimming structures; the controller generates control signals according to the electric signals, so that the dimming structures corresponding to the photosensitive structures generating the electricsignals adjust transmittance of the corresponding material layers. The dimming device can accurately judge sunshine positions and directions to realize pixel-level adjustment of the dimming device.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a dimming device, a use method, a manufacturing method, a vehicle window, a vehicle rearview mirror and a vehicle. Background technique [0002] In the process of returning to the car, the glare from the opposite, sideways or rear cars is an important factor that affects the sight of the driver and passengers and causes hidden dangers in driving safety. The glare irradiated on the window produces a visual blind spot, which affects the passenger's ride. Experience, so that the driver can not pay attention to the road conditions, very dangerous. [0003] To solve this problem, people have proposed many solutions, such as modifying the lights, adding polarizers, and wearing polarized glasses, etc., but this method reduces the light transmittance of the line of sight to receive light, and it also has certain safety hazards when driving at night , with the development of electroch...

[0002] In the process of returning to the car, the glare from the opposite, sideways or rear cars is an important factor that affects the sight of the driver and passengers and causes hidden dangers in driving safety. The glare irradiated on the window produces a visual blind spot, which affects the passenger's ride. Experience, so that the driver can not pay attention to the road conditions, very dangerous

[0003] To solve this problem, people have proposed many solutions, such as modifying the lights, adding polarizers, and wearing polarized glasses, etc., but this method reduces the light transmittance of the line of sight to receive light, and it also has certain safety hazards when driving at night , with the development of electrochromic and liquid crystal materials, a new application of optical fiber adjustment using dimming glass has emerged. This type of invention controls the light transmittance of the dimming film attached to the window by adjusting the input voltage, so as to realize the overall or The disadvantage of light adjustment in the anti-glare area is that the visual difference between the anti-glare area and the non-anti-glare area is too large, which also affects the driver's judgment on the road conditions, and although the light sensor is integrated in the solution to realize the dimming function. Automation, but it often needs to be installed around the glass structure, lacking accurate judgment on the location and direction of strong glare
