Cockpit of the Future

Cockpit of the Future

Advanced vehicle technology enables drivers and passengers to enjoy a growing range of in-car entertainment options.

Increasingly detailed and interactive displays not only greatly enhance the driving experience, but also improve the safety of the driver and his passengers. As the number of screens in vehicles has increased significantly in the last 5 years, not only the display technology for the automotive industry has to evolve rapidly, but also the necessary backlights are continuously adapted with the latest technologies.

MinebeaMitsumi has a long history of developing and manufacturing automotive components, such as backlights, for OEMs and automotive suppliers. Our engineers draw on many years of experience with a wide range of technologies and are well versed in the demanding requirements of the automotive industry. A particular focus for backlights is the temperatures, durability and as well as high performance required in a vehicle environment.


Large size Backlights

Growing trends in the automotive sector are increasingly larger displays that deviate from the standard shapes and are characterized by a free-shape design or a curved display.

MinebeaMitsumi is constantly developing new technologies, such as curved and freeform designs, to meet these requirements and promote a higher level of comfort.

The first large size Backlight, which has a size of more than 20 inch has a flat shape with two round corner.

With the same size of landscape and two round corners, the second large sized one is curved.

The third one is a direct type Backlight in rectangular form with curved design.

Narrow Border Backlights

The thickness is particularly important for thin display modules in the automotive sector. In addition, more and more attention is being paid to the thinness of the frame, which makes the display appear larger and more elegant.

Especially for these applications, MinebeaMitsumi has developed the Narrow Border Backlight.
