Projection technology to achieve head-up display is expected to be applied to cars

In this year's International Consumer Electronics Show (CES), Texas Instruments has created the most compelling mobile technologies and mobile multimedia experiences for personal and business consumers through its Digital Optical Processor (DLP) Pico technology. Many new application areas other than traditional projections involve industrial, medical, automotive and scientific instruments. Wang Yangxi, TIDLP’s Technical Sales Manager for Asia, stated that DLP's embedded projection technology can help developers create, store and project coherent high-speed graphics with ease. This will help small-size, low-cost and intelligent high-speed graphics display devices. The development and application. Among them, with TI and the world's top car manufacturers, show DLP technology in the automotive field of new applications the most representative.

Those who have played flying games should be familiar with the head-up display function on the screen. The latest news from TI shows that in the near future, this head-up display function will be expected to be applied to the car: that is, the driver of the car can see relevant driving data from the windshield without having to divert the line of sight, thus providing Higher security. Wang Yangxi said that the use of projection technology to achieve head-up display has been applied to both Audi and Mercedes concept cars, and has been demonstrated especially at the 2012 CES. This means that car manufacturers have recognized DLP technology and began to try to apply it to the car, but its time to market depends on the planning of each car manufacturer.

It is said that the principle of this technique is to reflect the content of the picture into the eyes of the person through the reflection of the mirror. For example, Mercedes-Benz concept car F125, in the driver's position above the dashboard, the location of the windshield, using projection technology, and added Microsoft's interactive features, you can achieve the effect of touch screen. With this feature, the driver does not have to look down at the buttons on the car's center console while he is driving. He only has to look at the screen in front of him to operate. At the Tokyo Motor Show, concept cars such as Toyota and Mitsubishi are introduced. The rear projection display technology is applied to control the car through interactive technology, and DLP technology can provide the best solution for such products with projection display on uneven surfaces.

In addition, DLP Pico display technology has other more advantages: for example,

1. Can be projected on any non-planar, but also can project different shapes;

2. In the closed condition, the screen can be completely black and will not obstruct the driver's line of sight;

3. Higher resolution, can project a clearer picture;

4. In high temperature cars, DLP technology products can work properly;

5. Larger screen size, 2.5D and 3D images can be achieved;

To this end, TI has introduced a new plug-and-play module, DLP LightCrafter, which is manufactured by Taiwan's YoungOptics. Its core is designed with reference to the TIDLP 0.3 WVGA chipset. The chipset was used in DLPPico projectors in the past to support reliable, high-speed spatial light modulators, including two major components: one is the DLP3000, which is a MEMS device consisting of 415,872 micromirrors; the other is the DLPC300. It is a digital controller that provides a convenient user interface that ensures reliable, high-speed operation of the micromirror array. By expanding the performance of consumer DLPPico projectors, the 0.3 WVGA chipset can display up to 4000 binary patterns per second.

DLP LightCrafter also includes the DaVinci TMS320DM365 embedded processor, 128MB NAND flash memory for storage mode, and configurable I/O triggers for integrated cameras, sensors, and other peripherals. The embedded Linux operating system can support user-friendly interfaces, enhanced functionality, and a customizable platform. In addition, DLP LightCrafter combines the 0.3WVGA chipset with an RGB LED light engine capable of producing more than 20 lumens of light output, thereby maximizing DLP LightCrafter performance to meet the specific needs of developers.

In the design of non-contact three-dimensional fingerprint scanners and other biometric technology products, TI uses DLP and structured light illumination (SLI) technology that projects light moving stripes onto objects, and uses algorithms to measure the distortion of reflective patterns. To rebuild the 3D shape of the object. The development kits provided to OEMs include DLP and a library of algorithms that recognize 3D shapes, surfaces, profiles, roughness, and discontinuities to help manufacturers develop fast, accurate contactless 3D scanning and identification system. Wang Yangxi emphasized that this system can use all kinds of light sources, including ultra-ultraviolet light to near-field infrared, which has greatly exceeded the constraint that only visible light can be used in the field of consumer micro-projection.
