Just like the projector, the light source of the head-up display has gradually changed from traditional light bulbs to LEDs to today’s laser pointer technology. The first laser head-up display first appeared at the Consumer Electronics Show in Las Vegas in 2011. Audi and Pioneer each exhibited this technology.
Take Pioneer’s products as an example. It mainly uses RGB laser technology, uses high-power red, green, and blue monochromatic lasers as the light source, and mixes them into full color. When the scanning speed is higher than the critical flicker frequency of the image, it can To meet the requirement of “visual residue” of the human eye, the human eye can observe clearly.
Compared with the traditional head-up display, the data displayed by the laser technology will be clearer, and it can be seen clearly even in the outdoor with strong sunlight. In addition, the data displayed by the laser technology will be better than that on the traditional motherboard Welding LED to display data is more flexible.
The first to apply laser head-up displays to mass-produced vehicles is the first time a laser head-up display is installed on its new generation of XE models. This head-up display is the industry’s first use of laser projection technology. Compared with traditional equipment, laser projection onto the windshield can reduce the interference of external light and shadow, display clearer pictures and higher contrast. In addition, in addition to providing information about vehicle speed, navigation, and maps, the volume of the laser head-up display is smaller than traditional equipment, and the weight is reduced by 1/3.
According to market research companies, the global head-up display market demand will reach 9.02 billion U.S. dollars in 2020, with an average annual compound growth rate of 26.23%. The green laser pointer head-up display benefited from its unique advantages and will continue to increase its market penetration.
Laser headlights, laser radars and laser HUDs have all been used in mass-produced vehicles. However, the application of laser technology in automobiles is not limited to this. For example, research institutions and automobile manufacturers have begun to try to use lasers in spark plugs of engine ignition systems to improve combustion efficiency.
In addition, car manufacturers use lasers for gesture detection and ranging (the principle is equivalent to the aforementioned lidar), which is used in gesture control systems for system control. Looking forward to the future, with the continuous development of technology and the emergence of new demands, lasers will exert more potential to meet the needs of automobiles for safety, environmental protection and intelligence.
