In this TI DLP Labs video, we will 
describe some key advantages of using DLP technology 
for high-resolution headlight applications 
and describe some typical use cases. 
DLP technology enables incredibly high-resolution 
headlight modules. 
The automotive-qualified DLP5531-Q1 DMD, 
or Digital Micromirror Device, has over 1 million pixels. 
And there's no sacrifice to style 
when the final lens height of a DLP5531-Q1 headlight module 
can remain under 40 millimeters. 
A headlight module that uses DLP technology 
can be designed with LED or laser illumination. 
DLP technology has been proven over 20 years in markets 
such as cinema and enterprise projection, 
and now it's automotive-qualified 
and in production vehicles today. 
What can a headlight do with 1 million pixels? 
One application is Adaptive Driving Beam, or ADB. 
ADB allows the high beam to remain on continuously 
while shaping light around oncoming traffic. 
DLP technology's high-resolution allows 
precise illumination control, put light 
exactly where it is needed so more of the high beam 
can remain on at all times without blinding oncoming 
traffic or pedestrians. 
More light can show drivers and ADAS systems everything 
in view, giving them more time to react to changes if needed. 
High resolution can also create smooth, gradient transitions 
in the light shape to avoid rapid, jerking motion of light 
that can be seen in low-resolution ADB options. 
Use the full programmability of high-resolution headlights 
to reinvent how vehicles and drivers see at night. 
Highly reflective road signs can glare drivers and oversaturate 
camera sensors. 
With high-resolution DLP technology, 
the headlight can dim or turn off 
pixels to avoid glare for the driver or camera 
while highlighting pedestrians, cyclists, 
and obstacles to give the driver and ADAS systems time to react. 
And ADB is only the beginning of what 
a high-resolution headlight can do. 
Any custom content can be displayed on the road. 
This enables a new communication channel between the vehicle 
and the driver. 
Here, the headlights are used to project lines indicating 
a vehicle path and to show the vehicle width as it traverses 
a narrow construction zone. 
Lane marking can give drivers and also other cars 
more confidence to safely navigate through hazards 
by communicating intent. 
Only the highest resolution makes symbol projection 
possible. 
Symbol projection enables welcome messages 
to the driver, differentiated branding, navigation, warnings, 
and other vehicle-to-everything, or V2X, communication 
to be conveyed on the road. 
Here, an arrow and distance are projected onto the road 
to indicate where a turn is located. 
But how many pixels does a headlight really need 
to perform these functions? 
To answer that, let's look at the navigation symbol 
that was projected on the previous slide. 
We can assume the headlight is mounted in the vehicle 
approximately 60 centimeters above the road. 
The symbol is 2 meters long and projected 
at a distance of 10 meters. 
Because of the steep angle that this symbol is projected 
on the ground, it actually fills less than 1 degree 
of the headlights' entire field of view. 
These images show the flattened image 
from the headlights' perspective. 
In a typical design, the DLP5531-Q1 DMD 
is able to use 50 to 100 lines of pixels 
to display this symbol due to its high pixels per degree, 
depending on the optical design. 
Other so-called high-resolution headlight technologies 
struggle with too few pixels for this level of detail.
