TI DLP ® is TI a patent technology, aimed at the optical processing system using MEMS technology.
The most important part is DMD, Digital Micromirror Device. The principle is to form a mirror array on the chip by MEMS technology, and reflect the optics by adjusting the deflection Angle of the mirror, so as to present various images. The DMD chip was invented by TI's Dr Larry Hornback in 1977. At the very beginning, it was mainly for the purpose of developing the imaging mechanism of printing technology. The micro-mechanical control was first developed with the analog technology, and then the Digital control technology was changed into the Digital micro-mirror Devices in 1981. It was officially named as the Digital micro-mirror Devices and began to be divided into the two directions of printing technology and Digital imaging. In 1991, TI decided to separate the development of digital imaging into a business unit, and developed the first digital image product in 1996. In 1997, TI officially terminated the research and development of printing technology, and went all out on the research and development of digital image.
Does god close a window when he closes a door? Obviously not. DMD, which was originally intended to revolutionize the printing technology, has shown great promise in the field of image display. The man on the wall wanted to float
The earliest DMD device of | only had 840 microscopes. Now there are more than 8 million microscopes in one DMD device.
| this is the simple principle of DLP imaging, which can be obtained by optical transmission, DMD and image controller for reflection control, and finally form a pattern for amplification.
Mozi refused to accept: it does not look much more difficult than pinhole imaging
What does a DLP system look like?
This is a typical DLP imaging system diagram, including system front-end processing, light source, DMD driver and DMD chip.
TI: I have DMD, I have controllers, I have processors, I have power management and other analog products, and only I can provide the most complete solution for this technology.
Where are the current DLP technologies used?
DLP technology has excellent optical properties, so any application related to light is likely to be used.
We look at the DLP technology can be seen in the 30 years of history, can be roughly divided into three stages, the first decade or so is technology preheating period, the second stage is the development, main application fields and the projector is the cinema, and since 2009 the third stage is the outbreak of the DLP technology, can be seen in the micro, automotive, industrial, and other fields, DLP technology has made breakthrough progress.
According to
Currently, DLP projectors account for more than 85% of the global digital projector market and more than 90% in China. Because of the DLP technology in the field of display contribution, has won an emmy award and an Oscar, an engineer got the Oscar, from then on to the peak of life, and some people compared...
Why a year before me?
TI has long wanted to bring DLP technology to consumer electronics. More than a decade ago, some tuhao might have had DLP in their homes. However, there are some fatal defects. First of all, the life of the backcast light source is not long, which requires thousands of hours to change the light source. The second problem is that the focal length is too long, so it is big and stupid, which is very inconvenient to install.
Let's take a look at the size and weight of the original rear projection TV... Bigger than you heavier than you, the key occupied nearly a square meter of space, so... Congratulations to the original in order to put the back to buy a big living room friends, early TV money earned back.
In 2009, TI hopes that projectors can be combined with consumer electronics, so it launched DLP Pico technology. In addition, with the development of light source and the whole optical structure, short focus technology, many micro-projectors are born. In addition to micro investment, the current 4K laser TV market, is also the use of DLP technology.
Look at the size and weight of the current laser TV... Nevertheless also congratulate the friend that buys laser TV now, besides the price is lower than liquid crystal besides, still saved very big space.
The car
| actually automobile HUD is also a part of display, but because interior space, thermal management, display load and so on are more special, more special technologies are needed.
DLP technology tries in AR HUD head-up display and intelligent headlamp.
For |, for AR HUD, DLP technology has such features as wider perspective, farther virtual image, brighter display effect, support for wearing sunglasses for viewing, and better temperature resistance.
| commercial HUD technology about today for 7-8 ° FOV visual Angle, unable to display more information, real AR characteristics, FOV need more than 12 °, and when to 20 °, HUD technology lane can display information and other more ADAS elements.
As you can see, as the viewing Angle increases, the more content you can carry
In 2017, the Continental model released by Lincoln adopted DLP technology for HUD development. Meanwhile, in 2018, the navigator will load a brighter and wider HUD with DLP technology.
It feels like there will be a car version of warzone in the near future
For intelligent headlights, DLP technology can achieve anti-glare, projection of custom signposts and other personalized functions.
Cameron university has developed an intelligent headlamp that can identify objects around it
The "smart and thoughtful" headlights were developed by engineers at the robotics institute at Carnegie Mellon university (CMU).
Anxious to ask, if I converted my porsche into smart headlights, and projected a heart, I can catch the girl I love?
The sensing
Sensing applications, mainly using DLP technology for spectral scanning. At present, the spectral analysis using DLP technology mainly focuses on near-infrared light, which can support the spectral analysis from 900nm to 2500nm. This is also due to the obvious biological characteristics in the nir part, including food safety, ingredient detection and other fields.
In addition to the spectral scanning of |, DLP technology can also be used in 3D scanning modeling. Because DLP technology can flexibly generate various structural lights and also supports different light sources, it is convenient to detect different substances.
| USES DLP technology with structured light products, which is equivalent to the status of bog fish in pokemon
industrial
With the continuous breakthrough of DMD, light source and other technologies, TI sees the prospect of high-end industrial market. Because DLP technology supports ultraviolet light, it can be used in some special fields.
Such as digital exposure, 3D printing and other functions.
So what is beginner's mind? At the beginning of the design of the printing market did not open, after a circle, back to the digital exposure printing market, so capricious.
DLP technology is so cool, not only the DMD and the controller itself, but also the cooperation of optical manufacturers, solution providers, light sources, lenses and so on.
TI has built an ecosystem, so if you want to experience it, come on in.
