Designing daytime running lights, part 1: adding one-fail-all-fail LED fault detection

Daytime running lights (DRLs) are becoming more popular in vehicles and are even a requirement in some countries. As I’m sure you can guess, DRLs are on during the day, which requires them to be very bright. As a designer, you typically have two choices to achieve the desired DRL LED brightness: Increase the number of LEDs in your string...

Create high-resolution adaptive headlights Using DLP technology

To achieve a glare-free high beam in a headlamp, designers can now turn to pixel-level digital control. Traditionally, a typical automotive headlight beam only illuminates what’s in front of a vehicle to improve visibility for drivers in low-light and poor weather conditions. Low beams illuminate the road a short distance in front of the vehicle...

How to design high-resolution retinal limited displays in an AR HUD

Instead of using the digital cluster or infotainment screen to deliver critical driving information, some auto manufacturers are beginning to use augmented reality (AR) head-up displays (HUDs) or near-field windshield displays to present this information directly in the driver’s line of sight. These displays must be high resolution so that drivers...
