Automotive lighting matrix control technology is the crystallization of the close integration and mutual penetration of light source technology, electrical technology, microelectronics technology, sensing technology and communication technology. The core of its control technology is to divide the near and far light patterns into multiple areas with an unequal number, and to switch or adjust the brightness of each area according to the data input of the camera or sensor and the preset algorithm.
The more zones are subdivided, the more light patterns that can be combined, and the more complex intelligent lighting actions can be realized. With the increasing number of sub-regions and the shrinking of the area of individual areas, the industry has begun to use the concept of "pixels" in display technology to refer to such areas.
Matrix control can maximize the brightness of road lighting while preventing the glare of the oncoming driver, improve driving safety and high beam field of view; according to statistics, every 30 meters of increase in the irradiation range can increase the reaction time by 1.3s, helping to reduce the occurrence of traffic accidents.

In 2013, matrix LED headlights were first installed on a production model--- Audi's flagship Sedan A8, which was developed and manufactured by HELLA HELLA.

When it comes to matrix headlights, it is impossible not to mention the "lamp factory" Audi. The Audi A6 e-tron concept car, which was unveiled at auto show 2021 Shanghai, features digital matrix LED headlights that project images almost to cinematic quality.
For example, while charging or resting, the Audi A6 e-tron concept car can be parked in front of the wall, and the virtual view of the game can be projected onto the wall in XXL format through the Digital Matrix LED headlights, rather than on the small screen in the cockpit, so that the driver and passengers will no longer have to wait boringly and can spend this time enjoying videos or games.
At the same time, we can see that not only the near and far lights, three rows of definable DRLs, matrix control, bring flexible and delicate dynamic effects.
In the future, the matrix position light/day running light will also be a design language of the car, the logo of the brand.
Entering the era of new energy vehicles, more and more models are equipped with matrix lighting technology, and lamp upgrading has become one of the important means to enhance the competitiveness of vehicles. It is reported that volkswagen group ID.4X has achieved the standard matrix headlights of the whole series.

In the face of such a trend, INTI Xinwei will soon release the matrix control chip IND83080, a domestic matrix control chip, to take you to embrace the era of intelligent lighting.
