BOE makes the glass substrates used in semiconductor packaging in its sensor business unit. The four tracks it set out to earn money outside displays have climbed to 26% of revenue, but open the filings and 18 points of that are TVs and monitors. The only business that display processes actually crossed over into is sensors, and it is 0.41% of revenue. And in the first half of 2026, the core display business slipped into decline.
A hard coat does a different job on every substrate. On film it lends hardness to a soft base and fights curl; on automotive PC it is graded by Taber haze instead of pencil hardness; on UTG it takes pen drops as a layer softer than the glass. Even a pencil hardness of 9H cannot be compared unless the load and the substrate are written down with it.
Researchers at Yonsei University and the University of Cambridge built a near-infrared OLED from a radical emitter. Switching hosts dropped the film photoluminescence efficiency from 21% to 8%, yet device efficiency stayed almost the same at 6.2% and 5.7%. Charge balance made up for the photoluminescence loss. Securing both together delivered an EQE of 8.1%, and holes were identified as the culprit that cuts efficiency at high current.
From October 5 to 11, 1,192 papers published in 28 major journals were checked, narrowed to 87 first-round candidates, and 18 are introduced here. One in-depth article is covered separately. This window brought together work on where efficiency and lifetime part ways, and on blue. Liquid crystals and reflective displays returned with four papers after a long gap, and with blue, green and red all present, this window alone fills out RGB.
The two OLED patents behind the $191.4 million jury verdict against Samsung in November 2025 came not from displays but from lighting. They date from OSRAM's OLED lighting days, and on August 11, 2020 they passed to a patent assertion entity that changed its name the same day. After the US Patent Office's tribunal later cancelled a single claim and put half the damages in doubt, the two sides settled the suits on October 8.
On the iPhone 18 Pro, the screen above Face ID leaves every other row of pixels empty. Under-display camera pixels went from a 1st generation that removes pixels to a 2nd generation that moves the circuits to the edge and lays transparent wiring, and the first to claim that 2nd generation was China's Tianma. But transparent wiring added masks, and Apple chose a 1.5 generation that goes back to removing pixels. Apple itself first described that arrangement in a 2018 specification and drew it in a 2020 filing.
Today the anti-static layer sits not on the screen but on the protective film that gets peeled off and thrown away. Static is generated at the very surface that separates, so the anti-static layer moved from the base film to the adhesive face, and every reduction in static brought contamination and corrosion with it. The mainstream PEDOT:PSS is expensive but survived because it is used as thin as 0.03 micrometers, while CNT, which meets the same condition, still has to clear the wall of dispersion.
Until now, metasurface holograms needed a laser. Researchers at the University of Toronto produced them with a halogen lamp. A Q-200 resonance compresses a 300-nanometer band to under 4 nanometers, so the device generates coherence itself. That flips the strengths and weaknesses of laser holograms: speckle averages itself out and shrinks, while thin strokes blur.
