Active glare prevention method and device based on OLED display technology

Abstract

The invention relates to an active glare prevention method and device based on an OLED display technology. The method comprises the steps that an OLED organic thin film provided with a plurality of mutually-independent OLED organic thin film partitions is inlaid in a windscreen; the light strength of each light source is detected in real time; a light source which enables a driver of a vehicle to feel glaring is found, and the light source, eyes of the driver and the windscreen are positioned; and a partition, on the windscreen, of the focus of a light ray of the light source irradiating toward the eyes of the driver is found, and a drive voltage is controlled to adjust the light transmittance of the corresponding partition. The device comprises the windscreen provided with the OLED organic thin film, a controller, light strength detection equipment, light source position detection equipment and human eye positioning equipment; the OLED organic thin film is provided with the multiple mutually-independent OLED organic thin film partitions; and each partition, each piece of detecting equipment and the human eye positioning equipment all are in datum connection with the controller. According to the active glare prevention method and device based on the OLED display technology, active glare prevention can be achieved, driving safety is improved, and aging of the vehicle interior can be effectively retarded.

Description

technical field [0001] The invention relates to an active anti-dazzle method and an active anti-dazzle device for automobiles based on OLED display technology, belonging to the technical field of automobile lighting. Background technique [0002] With the rapid development of automobile technology, automobile driving safety has been paid more and more attention. Especially when driving at night, the lights of cars driving on the opposite side, the light of the flash of the road camera and the strong light in various emergencies will stimulate the driver's eyes and cause dazzling. At present, commonly used anti-glare methods include anti-glare headlights, anti-glare glasses, and anti-glare LCD screens. Among them, the anti-dazzling headlights can reduce the risk of dazzling the driver of the opposite vehicle to a certain extent, but if the oncoming car is not equipped with anti-dazzle headlights, it is very likely to dazzle the driver of the vehicle, which is dangerous.

Among them, the anti-dazzling headlights can reduce the risk of dazzling the driver of the opposite vehicle to a certain extent, but if the oncoming car is not equipped with anti-dazzle headlights, it is very likely to dazzle the driver of the vehicle, which is dangerous. Driver's driving safety

Although the anti-glare glasses can prevent the driver of the car from being dazzled, the driver must always wear the glasses, which brings great inconvenience to the driver, and the dazzling glasses cannot prevent strong light such as sunlight from entering the car. Therefore, the resulting aging of the interior cannot be suppressed or delayed
