Method, device and system for adjusting light intensity of front windshield, front windshield, and automobile

Abstract

The invention discloses a light intensity adjustment method, device and system for a front windshield, the front windshield and an automobile. The front windshield is divided into a plurality of regions, the light transmittance of each region is adjusted according to the intensity of light entering the human eyes through the region and a preset light intensity acceptance range, and therefore it can be ensured that the intensity of the light entering the human eyes through each region is a suitable light intensity so that a driver can drive under the comfortable light intensity, the dazzling strong light is avoided, and the partial darkness caused by strong light shielding is also avoided.

Description

technical field

[0001] The present disclosure generally relates to display technology, and in particular, to a method, device, and system for adjusting the light intensity of a windshield, as well as a windshield and an automobile. Background technique

[0002] The windshield can block the impact of the wind on the driver while the car is driving, while giving the driver a wide field of vision. However, ordinary windshields cannot intelligently adjust the light transmission intensity when suddenly exposed to strong light. The strong light will stimulate the driver's vision and affect the driver's normal judgment of the driving situation, thereby causing traffic accidents.

[0003] According to statistics, 60% of the world's traffic accidents occur at night, but the traffic flow at night only accounts for 20% of the total flow of the whole day, and the probability of traffic accidents at night is much greater than that during the day. At night, the probability of traffic acc...
