The indoor story for COB is already clear: it accounts for nearly 50% of fine-pitch sales value at P1.2 and below, and over 75% at P1.0 and below. But the real variable is now moving outdoors.

The signal from ISLE 2026 is that the competitive focus of advanced packaging has shifted from indoor control rooms and conference rooms toward outdoor advertising and retail. COB’s penetration in the outdoor and rental market is currently “close to zero,” yet that market exceeds RMB 20 billion. Several industry figures are calling 2026 the inflection year for outdoor COB.

Near-zero does not mean inaccessible. COB’s fully encapsulated packaging is inherently suited to outdoor conditions: IP65 protection without an additional mask eliminates the yellowing that affects SMD outdoor screens, while the “no-lamp-bead”structure removes the root causes of lamp detachment and dust accumulation.What held COB back outdoors was not protection capability, but cost and the pace of weather-resistance validation—both of which are being rewritten by indoor-scale manufacturing.

For Focono, this crossing is not a single-product pivot. The encapsulation experience accumulated in the COB Series indoors meets the weather-resistant design and thermal architecture proven in the K/E Series outdoors. The Cloud Series LED poster screen points to retail’s demand for flexible deployment and plug-and-play operation—35 mm thin, 38 kg, one person can reposition it. When COB’s display quality meets the deployment logic of outdoor and retail, the next market maybe more fragmented than the conference room—but also larger.
