Flexible Screen / OLED

Definition and Technical Principles

A flexible screen refers to a display panel that utilises a flexible substrate (such as polyimide, PI) instead of conventional rigid glass substrates, enabling the panel to bend, fold, roll, and adapt to various form factors. Due to its self-emissive properties and the structural benefit of not requiring a backlight module, OLED (Organic Light-Emitting Diode) is currently the primary medium for flexible display technology—each pixel emits its own light, allowing panels to be engineered exceptionally slim (down to 0.187 mm) while delivering ultra-high contrast ratios. Flexible AMOLED currently stands as the mainstream technological solution for in-vehicle flexible displays.

Core Advantages: Overcoming Cabin Space and Packaging Constraints

The primary value of flexible screens lies in resolving the packaging conflict between conventional rigid displays and interior cabin architecture. Visionox has introduced a dynamic cold-formed in-vehicle display solution featuring two 14.2-inch flexible AMOLED panels that bend rearwards for compact storage when not in use, seamlessly contouring with the curved cabin trim to maximise cabin space. At CES 2026, LG Display showcased a 33-inch flexible rollable OLED panel engineered with a 30R curvature (a bend radius of roughly 3 cm) that retracts neatly into the driver's dashboard assembly; it presents essential navigation data in a compact format while driving, and rolls out into a full 33-inch widescreen layout for infotainment when parked or in autonomous driving mode. Visionox also demonstrated an automotive-grade dynamic folding AMOLED solution that deploys when needed and folds away when idle via an inward folding radius of just 3 mm, having successfully cleared over 100,000 cyclic fold tests to meet stringent automotive durability standards.

Form Factor Innovations and Mass Production Deployment

In-vehicle applications for flexible displays continue to see rapid form-factor innovations. Visionox has rolled out an integrated dual-screen curved flexible AMOLED solution featuring an R50 cold-formed radius and an ultra-slim 3.0 mm bezel, enabling a seamless transition across display sizes from 12.3 to 14 inches. Its fixed-curve flexible AMOLED centre console display embeds directly into wood veneer and metallic dashboard inserts with an overall thickness of just 1.1 mm (tapering down to 0.1 mm in specific sections), and is currently fitted in models such as the Hongqi Guoya.

In terms of in-display integration, Samsung Display presented its HIAA (Hole in Active Area) technology at K-Display 2026. By precision-cutting an 80 mm diameter aperture directly through the OLED panel, physical switchgear such as rotary gear selectors and air-conditioning vents can be integrated straight into the active display area, perfectly balancing tactile control ergonomics with maximised screen real estate. Concurrently, Samsung launched its dedicated automotive OLED sub-brand, "DRIVE™", anchored by five core pillars including design differentiation, reliability, and intelligent safety, alongside the OTS modular platform offering 7 display configurations ranging from 7 to 17 inches.

OLED Visual Performance and Cost Optimisation

The display performance of automotive OLED panels continues to advance. At CES 2026, LG Display unveiled a large-format OLED panel boasting a peak brightness of 4,500 nits, powered by a new four-layer tandem light-emitting architecture to ensure crystal-clear legibility even under harsh, direct sunlight.

On the production cost front, LG Display revealed the development progress of its automotive Advanced Thin OLED (ATO) technology for the first time in 2026. Utilising glass substrates combined with thin-film encapsulation (TFE), ATO eliminates complex processes such as laser lift-off typically required for plastic OLEDs. This significantly trims manufacturing overheads without compromising display fidelity. A portfolio of five panel sizes ranging from 7.2 to 24.2 inches is currently planned, spanning digital instrument clusters through to central infotainment screens.

Technical Limitations

Several engineering challenges remain before flexible screens can be deployed across mainstream production vehicles: dynamic bending mechanisms must withstand tens of thousands of continuous articulation cycles, while folding and rollable mechanisms need to ensure silent operation and long-term mechanical reliability; expansive high screen-to-body designs must strictly comply with crashworthiness standards and avoid obstructing airbag deployment zones; and the thermal management and power consumption demands of high-luminance panels require further validation. Furthermore, flexible OLED applications are currently confined largely to premium and flagship models, meaning it will take time before production costs decline enough to penetrate mainstream vehicle segments.
