Curved Screens

Definition and Technical Forms

An automotive curved display refers to an in-vehicle screen unit utilising flexible OLED or specialised curved LCD technology, allowing the panel to take on a fixed curve or dynamic flexible form. Compared with conventional flat screens, curved displays seamlessly contour along the cockpit interior lines via physical curvature, marking an evolution from standard flat displays to intelligent shape-shifting interfaces. At present, automotive curved displays mainly come in two configurations: fixed curved screens (such as pillar-to-pillar ultra-wide displays) and dynamic curved screens (such as rollable or slidable panels tailored to various usage scenarios).

Key Technical Indicators and Products

In the fixed curved display segment, Tianma Microelectronics' 49.6-inch panoramic immersive Tianxuan screen unveiled in 2025 features an R3000 ultra-curved radius, stretching from the left to the right A-pillar. It integrates the instrument cluster, centre infotainment, front passenger entertainment, and electronic rearview mirror displays across an expansive 1.25-metre span. Equipped with ACRUS pixel-level local dimming technology, the panel delivers a 100,000:1 contrast ratio and keeps windscreen reflection below 0.55%, ensuring crystal-clear legibility even under harsh direct sunlight. Concurrently, Tianma introduced the Liuyun curved centre console Tianxuan screen featuring an L-shaped profile, an extreme R40 mm bending radius, and a 138° optimal angle, boasting a slim 1.9 mm body whilst nearly doubling touch response sensitivity.

In the flexible dynamic display arena, BOE has rolled out a 15.6-inch on-cell L-shaped curved OLED centre display. Featuring a 135° fixed bend angle designed around the natural reach of the driver's arm, it reduces the reach distance to high-frequency controls by 30%. Meanwhile, Visionox's C-shaped fixed-curve centre console screen tackles the issue of inaccurate touch inputs whilst driving through a tight-radius curvature design.

Core Advantages and Values

The value of curved screens in smart cockpits spans three key dimensions. In terms of immersive visual experience, pillar-to-pillar curved displays eliminate visual breaks between traditional instrument clusters and centre screens, creating a seamless, borderless field of view. For ergonomic optimisation, fixed curved displays follow the natural angle of driver interaction, shortening reach distance and improving the accuracy of blind operation. Regarding interior aesthetic integration, curved screens blend effortlessly into streamlined cabin architecture, evolving from mere functional modules into an emotional intelligent space.

Industry Trends

Flexible OLED technology is steering automotive displays into a new "flexible era". Beyond fixed curved layouts, dynamic form factors—such as slidable displays (e.g., Visionox's 14.2-inch slidable rollable AMOLED centre display with 75 mm travel) and rollable screens (such as BOE's 31.6-inch tiled sliding rollable display)—are rapidly making their way into production vehicles. Industry trends indicate that curved screens are shifting from "fixed curvatures" to "on-demand morphing", allowing a single display to seamlessly transition between a vehicle control interface and a cinematic entertainment screen.

Technical Limitations

Nevertheless, curved screens face several hurdles in mass-market automotive applications. Flexible OLED panels must maintain display fidelity and surface flatness across over 100,000 sliding or rolling cycles. High-brightness output also introduces power consumption and thermal management concerns—while Tianma's IRIS HUD solution caps power draw at 6W, heat dissipation under extreme operating conditions still demands rigorous testing. Additionally, the crash structural integrity of pillar-to-pillar curved screens, clearance for airbag deployment paths, and high replacement costs remain critical engineering challenges.
