Скачать или смотреть BOE 17-Inch Rollable OLED, 4 mm Radius & 3.2:1 Extension | Display Week 2025 Flexible Panel

BOE’s latest f-OLED prototype shown at Display Week 2025 measures 17 inches when fully unrolled yet curls around a core only 4 mm in radius. The concept tablet transforms from a pen-sized cylinder to a full desktop-class screen thanks to a 3.2:1 extension ratio and can be wrapped through 6.5 complete turns without creasing. These figures establish a new flexibility benchmark for large-format OLED and hint at genuinely pocketable workstations, sketchpads, or field monitors. https://www.boe.com/

Mechanically the panel relies on a multilayer polyimide substrate, ultra-thin barrier coatings, and an oxide TFT backplane optimised for low-stress bending. A staggered hinge cassette and high-elongation laminated adhesive distribute strain uniformly so that the sheet survives thousands of roll–unroll cycles; BOE’s internal testing quotes at least 6.5 full windings with a 272 mm bend span before any optical drift is measurable.

Optically the demonstrator inherits the tandem-stack architecture BOE introduced for high-brightness mobile OLEDs, delivering 10-bit colour, 97 % BT.2020 gamut and peak luminance above 1200 nits while holding differential ageing in check. Integrated touch, 360 Hz pen sampling and HDR10 rendering are driven by an oxide backplane clocked at 240 Hz, enabling latency-free stylus input for CAD and animation workloads. These metrics position the rollable sheet close to laptop-grade panels rather than the lower-spec flexible displays of earlier years.

The company framed the rollable tablet as part of its “ONE” sustainability programme, highlighting reduced material mass, recyclable magnesium housing, and AI-assisted power management that can cut OLED drive energy by 20 %. In BOE’s roadmap the device succeeds the 15-inch rollable shown in 2023, whose 10 mm bending radius now looks conservative; shrinking that figure to 4 mm underscores the pace of f-OLED material and hinge improvements. Together with concurrent α-MLED and UB Cell demonstrations, the rollable display signals a broader shift toward convertible form factors that let end-users scale canvas size to the task rather than the chassis.
