3M material solutions for automotive information displays
Application spotlight: eMirrors
-
What does it take to transform a simple rearview mirror into a multifunctional information display? At 3M, we know the answer lies in clarity, functionality and maximal design freedom.
We’ll help you craft a crystal-clear digital display that transfers seamlessly between mirror and LCD modes. Deliver clear, bright signals with minimal distractions. Place mirror display modules wherever your design requires: higher on the dashboard, on door panels, on A-pillars and even across multiple separate eMirrors. With 3M Science, make the eMirror stand out in your automotive HMI design.
-
In mirror mode, reflect light just like a conventional mirror. In LCD mode, optimize display brightness and clarity by transmitting up to 90% of the backlight.

Maximize brightness and efficiency for better readabilityWe’re entering a new era of Human Machine Interface (HMI). Automotive display designs must support an ever-growing assortment of information and data: audio systems, navigation systems, vehicle cameras and various driver-curated apps, just to name a few. On-axial luminance, readability and efficiency in automotive displays are essential for safe, differentiated customer experiences. 3M provides advanced brightness enhancement and reflective polarizing films to help you achieve demanding display requirements: increase backlight efficiency, transmit more light and prevent moiré effects. Our prismatic, multilayer optical technologies recycle and direct light where it is most needed.
3M™ Dual Brightness Enhancement Film (DBEF)
-
Decrease reflections — and distractionsAs information displays grow larger and move higher on the dashboard, managing reflections becomes critical. 3M™ Advanced Light Control Film (ALCF) helps OEMs enable cockpit designs to meet their increasing demands of modern digital displays by controlling and directing light to exactly where it is needed — and reducing light from where it can become a distraction. 3M ALCF is a louver film that controls the distribution of light perpendicular to the louver structure (viewing angle) to help create privacy, minimize ambient reflections and improve display contrast.
-
Reimagine mirrorsCreate dual-function displays that deliver immersive experiences with optimal clarity and brightness. In full mirror mode, with backlight off, 3M™ Reflective Polarizing Mirror reflects as proficiently as a conventional mirror. Because the film is optically flat, the image won’t be distorted. In LCD mode, with the backlight on and film and LCD transmission axes aligned, >90% of light is transmitted, optimizing the brightness of the eMirror image display.
3M display bonding
-
Our foam tapes, structural liquid adhesives and optically clear adhesives can help meet a range of bonding challenges: impact absorption, fatigue resistance, moisture resistance, environmental robustness, anti-shatter, light efficiency and transfer, and more.

Deliver bigger, thinner and more curved automotive display designsEnhance design flexibility by combining the strength and reliability of an acrylic adhesive with the conformability of an acrylic foam core. 3M™ VHB™ Tapes bring a rare balance of performance to automotive display bonding. Energy-absorbing, viscoelastic tapes help control shock and vibration to protect sensitive display designs from impact and cyclic fatigue. They provide strong adhesion strength and heat resistance, while their premium sealing with 100% closed-cell construction keeps out contaminants, moisture and chemicals. Tapes are convenient, easy to use and can be die cut into pre-formed shapes.

Improve stability and resilienceAutomotive display bonding solutions from 3M are designed to deliver excellent static tensile strength and shear performance with high peel adhesion. With plenty of strength even for bond lines below 0.5 mm wide, our liquid urethane adhesives are excellent for thin device designs and assemblies. These one-part adhesives deliver the reworkability of a polyurethane-reactive adhesive (PUR) — often critical for recovery of valuable displays — but can be laminated as a pressure sensitive adhesive for immediate handling strength.

Secure your flexible printed circuits (FPCs)
Virtually invisible, high-strength bonding solutions from 3M include double-coated tapes and adhesive transfer tapes ideal for FPC thin bonding applications. Double-coated tapes are effective for dissimilar materials with different bonding properties, while adhesive transfer tapes contain no carrier and are thus extremely conformable to intricate designs with irregular surfaces. Tapes from 3M are convertible to provide accurate edge profiles and can accommodate fast or high-temperature processing.
