BOE is building glass-based optical interconnects for AI data centers

BOE, the Chinese display giant, is moving beyond screens and into the guts of data center hardware. The company confirmed late this week that it has established a dedicated project team for Micro LED optical interconnect systems and glass-substrate Co-Packaged Optics (CPO) technology.

CPO is one of the more promising approaches to a problem that keeps getting worse as AI chips get faster. Data has to travel between processors, and the traditional copper traces on circuit boards can’t keep up. By placing optical components — the lasers and modulators that send data as light — directly next to the compute silicon, CPO cuts power consumption and boosts bandwidth. BOE’s version uses Micro LEDs as the light source and a glass substrate as the carrier, an approach that could offer better thermal stability and lower signal loss than conventional organic substrates.

The company disclosed the effort in its latest investor relations filing. It is also working with Corning on several joint projects including glass-based carrier boards, optical interconnects, perovskite materials, and foldable glass. The partnership has moved into a substantive phase with quarterly progress reviews.

BOE also offered updates on its LCD and OLED businesses. On the LCD side, rising memory prices are expected to put some pressure on mainstream panel shipments, but growing demand for larger screen sizes should keep total area shipped higher year-over-year. The exit of older production lines is tightening TV panel supply, which BOE sees as a positive for industry pricing dynamics.

For OLED, BOE said shipments in the high-price, small-size segment are expected to rise, supporting demand for LTPO panels. On the mid-size side, AI PC launches and the ramp-up of AMOLED Gen 8.6 production lines should accelerate OLED adoption in laptops and tablets.

The CPO project is the most interesting signal here. Display manufacturers have been finding new uses for their core competencies — glass processing, thin-film deposition, precision optics — and BOE’s bet on glass-based optical interconnects suggests it sees a future where data center hardware starts to look a lot like display manufacturing.
