HUD trends

HUD (Head-Up Display) plays an increasingly important role in automotive electronics technology. It is a technology product
that allows drivers to directly see the display content of the car dashboard while driving. With the increasing demand for driving safety and the upgrading of automotive electronics technology, HUD technology is also constantly evolving and developing.

In the early reflective HUD, information was displayed through projection on a reflective mirror. In the Combiner Type HUD, the projection content is mixed with the outside scenery through a transparent glass. This projection method can maintain the driver's line of sight stability, but its display effect may be affected by external ambient light.

With the appearance of Windshield Type HUD, HUD technology has undergone a major upgrade. Windshield Type HUD no longer needs a transparent glass disc to achieve projection, but directly displays the projection content on the car's front windshield, which can achieve more realistic, more three-dimensional, and more stable projection effects. Windshield Type HUD not only allows drivers to drive more safely but also enhances their driving experience.

The latest AR HUD further enhances the performance of HUD. It can display information on the lanes and road signs, and provide more driving assistance functions, such as navigation on the road and warning drivers of obstacles ahead. AR HUD can significantly improve driver safety and convenience and is expected to become a necessary device for safe driving in the future.

Overall, with the continuous advancement of technology, HUD technology is also constantly evolving and upgrading. In the future, there will be more HUD applications that bring people a safer, more convenient, and comfortable driving experience.

AR HUD technical problems

Although AR HUD (Augmented Reality Head-Up Display) has many advantages when applied to cars, there are also many technical challenges that need to be overcome. First of all, the projection area of AR HUD is relatively wider than other types of HUD, so it requires a large panel, making the volume of AR HUD relatively large. Not every car model can directly incorporate this technology, which means that the configuration of car parts needs to be specially designed to support the application of AR HUD. This not only increases the difficulty of development and implementation, but also increases costs.

In addition, the imaging principle of AR HUD also brings another technical challenge. If AR HUD is directly applied on a regular windshield, it may cause the so-called "ghost image" phenomenon due to imaging principle problems, which requires the use of a wedge-shaped glass on the windshield to solve. However, this further increases the cost, making it more difficult to introduce AR HUD.

Finally, due to the large projection area required by AR HUD, the power consumption is also relatively high, which leads to an increase in the operating temperature of the product. Such a high temperature can cause certain harm to the product, which also increases the problem of heat dissipation. Therefore, the technical challenges of AR HUD, including the large size, difficulty of implementation and high cost, as well as the heat dissipation problem caused by high power consumption, all need to be solved in order to be more widely applied in cars.

Flat type AR HUD(MAVE)

UniMax Electronics is a company that specializes in HUD series products. Its products have excellent internal light path design, not only with the advantages of low power consumption and low heat dissipation, but also successfully introduced advanced MAVE technology, which allows the external light path to penetrate, reflect, and form images in a shutter-like way, thus achieving the projection of wide images without using large panels. In terms of the optical guide structure of the external light path, the brightness efficiency of the hologram technology used by other competitors is about 1%, while the brightness efficiency of the MAVE technology used by UniMax is at least 8%, and even as high as 30%, making it the only industry leader in the world that can introduce and mass-produce this technology. This leading technological advantage has made UniMax Electronics a leading brand in the HUD product market.

(Flat type AR HUD(MAVE),Reduce 30% volume to make it lighter, thinner)

With the assistance of MAVE imaging technology, the volume of AR HUD can be reduced by at least 30%, making it easy to embed in the internal space in front of the dashboard and applicable to most car models on the market. Additionally, AR HUD does not exhibit ghosting issues when imaging on regular windshields, eliminating the need for special wedge-shaped glass and greatly reducing the cost and difficulty of implementation. With the high-efficiency, low-power consumption Picture Generating Unit (PGU), AR HUD can solve common technical challenges at once, increasing production efficiency and saving costs.
