Intelligent signal displays

Dynamic exterior displays that enable context-aware communication, enhance safety, and open new design possibilities 

Exterior communication displays for modern vehicle interaction 

Intelligent signal displays (ISD) transform exterior vehicle lighting into an active communication interface, providing dynamic, context-aware visual cues for surrounding road users. As mobility moves toward richer interaction and automation, ISDs enhance safety and enable new design concepts. ams OSRAM supports these systems with high-resolution LEDs, micro-LEDs and intelligent driver ICs that deliver precision, clarity and durability. 

What are intelligent signal displays (ISD)? 

Intelligent signal displays are LED‑based display elements integrated into the front, side or rear of a vehicle. They communicate information to other road users, supporting V2X (vehicle‑to‑everything) scenarios or indicating vehicle states such as charging status. Because the technology is still emerging, several terms - such as interactive signal display, interactive social display, or interactive social and signaling display - are used interchangeably, all referring to the same concept. 

Technology overview: LEDs and driver 

ISDs typically use compact, automotive‑grade white LEDs, although red, green or other mono‑color variants may be used depending on the signaling function.

To balance brightness, visibility and power consumption, ISDs usually operate with hundreds of LEDs rather than thousands. This makes automotive multi‑channel LED drivers - with a high number of individually controllable channels - the preferred choice.

Design aspects for intelligent signal displays? 

Design requirements for ISDs are driven by both functional and aesthetic considerations. Because ISDs remain visible even when turned off, compact high‑brightness LEDs are used to deliver sufficient luminous intensity across varying viewing distances while remaining comfortable to look at up close. To avoid visual artifacts in video recordings—such as flicker or rolling‑shutter interactions—the driver architecture and refresh rate must be carefully designed. This is especially important as ISDs increasingly appear in media, traffic monitoring footage and safety‑relevant camera systems. 

FAQ: Below are some of the most common questions about Intelligent signal displays 

What is the difference between intelligent signal displays and an interactive grille illumination?

Grille illumination can be simpler and may provide only decorative or low‑resolution functions. As resolution increases, grille illumination can evolve into an intelligent signal display. ISDs, however, can be positioned anywhere on the vehicle body and can use multiple colors and signaling concepts. 

What are the differences between intelligent signal displays, interactive social displays and interactive social and signaling displays?

These terms are used interchangeably. The industry does not yet follow a standardized naming convention, but all describe the same category of vehicle‑mounted communication displays.
