From 3D printing to automotive smart headlights, what are the innovative applications of TI's unique DLP technology?

- Oct 13, 2019-

Recently, at the Texas Instruments DLP product innovation application media briefing, electronic enthusiasts saw that Texas Instruments (TI) DLP product line application breakthrough, no-screen TV to achieve 4K-level ultra-high-definition projection, to adopt the new DLP Pico controllers for mass-market 3D scanners, 3D printers, to new projectors, intelligent audio, DLP-based AR HUD instrument display solutions, and TI's DLP5530-Q1 car gauges at CES High resolution car headlight scheme.


Frank Moizio, global general manager of TI's DLP Pico product line, said DLP technology targets three major applications: first, display. Second, light control, that is, by controlling the light to do some applications. Third, the automotive electronics industry. In these three industries, TI's DLP products have their own unique advantages to ensure the company's leading position in the industry.


1. DLP technology is fast, can use rapid response and fast response to achieve product performance improvement, such as video field, on-site display of the combination of projection and interaction Hatch smart light and shadow magic screen.

2. DLP technology can support different spectra, especially visible light, and also has corresponding solutions for invisible light, infrared and ultraviolet light. For example, DLP can use UV light to cure liquid resin and liquid paraffin to achieve 3D printing.

3. DLP technology provides product platforms of different specifications. Different sized chips support different resolutions and different illumination levels. The customization of the chip allows the projection product to be made very small, and it can also be very bright and large. Product coverage is very broad.


Let's take a look at the trending products of DLP technology in applications:


Pocket projector: Reduced size, DLP230NP is only 0.23 inches, brightness efficiency can support up to 200 lumens of brightness, display 20 inches to 40 inches, and its dimensions are only 78mm x 78mm x 15mm (100 lumens).


The DLP Pico 0.23-inch chipset supports a wide range of next-generation ultra-portable display products such as smart home displays, mobile phone accessories Pico projectors, smart speakers with display, augmented reality and virtual reality wearables, and mobile smart TVs.


The DLP chip is available in custom sizes, including 0.2" and 0.3" 720P with resolutions from 360 to 4K. Taking 0.33 inch 1080P as an example, optical engine manufacturers can make different specifications of optical machines in different shapes to achieve product diversity and differentiated design. The optical engine can also be customized according to the different needs of the end product.


3D scanning and 3D modeling.


3. High-resolution car headlights based on DLP technology


TI's DLP5530-Q1 car headlight solution, the DLP chip for car headlights trial is a car certification chip, which can support the working range from -40 degrees to 105 degrees, is a completely car-grade product. .


DLP technology can also be applied to automotive transparent window projections, which can display enough information to provide more interaction while keeping the window transparency from interfering with the driver's field of view.


The intelligent headlights were first proposed in 1958. The light source is mainly composed of LED matrix type / LCD type / DLP type / uAFS type. Its function is mainly multi-road mode switching, intelligent follow-up steering, automatic recognition of the glare-free high beam of the incoming car. , road sign recognition and pedestrian warning.


Zheng Haibing, business development manager of DLP products in Texas, said that the DLP chip is composed of millions of micromirrors. DLP technology can provide higher precision for car smart headlights. When driving, the head-up display needs to project information. Come out, and the DLP projection can show the information within 20 meters of the front of the car. Therefore, when the user is driving, when viewing the information provided by the HUD, the user can continue to focus on the road conditions, and will not be distracted, thereby causing unnecessary safety hazards.


Zheng Haibing hinted at another possibility. DLP products combine touch technology and sensing technology. When encountering some road conditions, such as narrow roads, some drivers are more cautious if they can drive past, and a safe channel can be projected at this time. To ensure that drivers pass safely.


Conclusion:


The three advantages of DLP technology have gradually emerged on the application side. TI believes that it is necessary to build the DLP technology ecosystem with the help of partners, in order to quickly build products.


The customization of the DLP chip size allows the projection product to be made very small, and it can also be very bright and very large. DLP technology applications have evolved from traditional projection to ultra-portable display products such as smart home displays, mobile phone accessories Pico projectors, smart speakers with displays, augmented reality and virtual reality wearables, and TI is expanding DLP technology to more More field development. Such as industrial and automotive electronics. Its achievements include 3D printing and 3D modeling, as well as expanding in the field of automotive smart headlights.
