As a flexible and programmable light control device, DLP technology has achieved great success in display and related fields such as digital cinema and home entertainment. Today, designers in different fields are actively trying to bring the superior display and light control capabilities of DLP technology to a wider market, with innovative designs from industrial, medical, personal electronics and automotive applications. Recently, Wang Yangxi, business manager of Texas Instruments DLP China, said in an interview with EDN China, “As a provider of basic technology, TI is pleased to see successful applications of DLP technology in many fields, including individuals. Micro-projection in the electronics field, 3D printing and 3D measurement in the industrial direction, and the latest automotive field are all TI's most important and optimistic directions. To this end, TI hopes to build an ecosystem and provide more standardized products to support various differences. Innovative needs."
In-vehicle applications have received much attention as new DLP applications. Wang Yangxi said that DLP currently has three directions in the vehicle application, DLP vehicle interactive center console, car head-up display (HUD), and the latest smart headlights. The vehicle-mounted interactive center console based on DLP technology can realize the screen design of any size and curved surface, which is very important for realizing the special design of the internal car of different models. The manufacturer can achieve better design matching and design different screens for different models. In the shape of the center console, DLP technology can enhance the user interface experience by integrating the control buttons and display into a single screen through the tactile feedback function provided by the virtual/physical buttons. In addition, relying on DLP technology to provide higher resolution, brightness and greater touch sensitivity, it can be said that it provides a good design case for the future development of the car center console.
For the DLP head-up display solution that the outside world is concerned about, Wang Yangxi said that the head-up display currently used in the market is mainly based on TFT technology, but its viewing angle is generally limited to 3 degrees to 5 degrees, and the picture is not big enough. The restricted content display may only display some simple speed information or arrow signs, and the virtual display distance achieved by the vehicle is also relatively close to the car, which is about 1.5 meters to 2 meters. DLP can bring some new changes to the HUD design, such as providing a wider viewing angle, which can now be displayed from 7 degrees to 10 degrees, so that more information can be displayed. At the same time, DLP technology can maintain the characteristics and characteristics of motion at high and low temperatures, and does not cause sharp changes in color, contrast, and brightness. It is a very reliable technology used in the vehicle environment. With the development of DLP technology, there will be opportunities to achieve a larger perspective, such as 10 to 20 degrees, when more realistic and enhanced content can be achieved. For the specific listing plan of DLP heads-up display, Wang Yangxi also said that due to the design cycle and certification of the car manufacturer, there is an opportunity to see the DLP head-up display products available around 2016.
Smart headlight technology is also the focus of recent research. For the latest research results of DLP in this direction, Wang Yangxi said that in addition to the general intelligent control of the rotating position of the car headlights, an anti-glare headlight has recently been developed, which can capture the road brightness through the sensor, when the opposite When you come in, the headlights will also be adjusted to prevent glare. DLP's light control devices enable more sophisticated control over the range, brightness, etc. covered by headlamps. At present, many car manufacturers are interested in this, and are evaluating the adaptability of technology and technical needs.
