Montreal, July 27, 2026 — This past week was one of those stretches where the technology industry showed both of its faces at once. On one side, engineering at its most impressive: Samsung unfolded an entirely new generation of foldable phones in London, and the world's two biggest OLED panel makers confirmed that next year's televisions will be more than twice as bright as what most of us have in our living rooms. On the other side, the reminder that all of this hardware lives in a hostile environment: Microsoft shipped one of the largest Patch Tuesdays in its history, a popular browser extension with 1.6 million users was pulled for hiding data-exfiltration code, and a Big Four accounting firm confirmed a weeks-long breach. In today's edition we unpack the materials science of folding glass, the device physics behind the new brightness race, and the practical lessons of a rough week in security — with concrete advice on what to buy and how to protect it.

Today's Tech Radar

The ten stories that mattered most this week, before we dive deep into three of them:

Deep Dive 1 — The Galaxy Z Fold8 Generation: The Materials Science of a Phone That Bends

On July 22, Samsung hosted its Galaxy Unpacked event in London and introduced the eighth generation of its foldable line: the Galaxy Z Fold8, the Galaxy Z Flip8, and — for the first time — a Galaxy Z Fold8 Ultra, the first "Ultra" model in the company's foldable portfolio. According to Samsung's official materials, the Fold8 Ultra measures just 4.1 mm thin when unfolded, is reinforced by a dual layer of titanium beneath the display, carries an 8-inch foldable AMOLED main screen alongside a 6.5-inch cover display, and runs a Snapdragon 8 Elite Gen 5 for Galaxy with up to 16 GB of RAM, up to 1 TB of storage and a 5,000 mAh battery. Peak brightness on the panels reaches 3,000 nits at 120 Hz.

Why folding a screen is physically hard

To appreciate what those numbers mean, it helps to understand why a folding display is such a difficult object to build. An OLED display is a stack of extraordinarily thin layers: a substrate, a backplane of thin-film transistors that switch each pixel, the organic light-emitting layers themselves, a thin-film encapsulation layer that keeps oxygen and moisture out, a touch sensor, and a cover layer. In a conventional phone, the cover layer is rigid glass and the whole stack simply has to survive drops and scratches. In a foldable, every one of those layers must survive being bent through a radius of a few millimetres — hundreds of thousands of times.

The physics problem is bending stress. When you fold any sheet, the outer surface of the fold is stretched (tension) and the inner surface is compressed. The stress is proportional to the thickness of the sheet divided by the bend radius. That gives engineers exactly two levers: make the layers thinner, or make the fold radius larger. This is why foldable displays use ultra-thin glass (UTG) — glass drawn down to a few tens of micrometres, thinner than a human hair — laminated with polymer layers. At that thickness, glass stops behaving like the brittle plate we know and starts behaving like a flexible film, while still providing the hard, smooth touch surface that plastic cover films cannot.

The second lever, bend radius, is the job of the hinge. Samsung's newest hinge designs (the company brands the current mechanism "Armor FlexHinge") guide the display through a teardrop-shaped path when closed: instead of creasing the panel around a tight cylinder, the display forms a droplet of larger radius that hides inside the hinge cavity. A larger radius means lower stress at the fold line, which is why the visible crease on modern foldables is so much shallower than on the first generation. Samsung also says the Fold8 generation pairs the new hinge with an improved OLED panel to deliver a nearly crease-free experience, with a dual titanium layer beneath the display lending stiffness without much weight — titanium's strength-to-density ratio is roughly twice that of the aluminium used in most phone frames.

Thermals, batteries and the 4.1-millimetre problem

Thinness creates its own engineering debts. A 4.1 mm chassis leaves very little vertical space for a vapour chamber to spread heat from the processor, and lithium-ion pouch cells lose capacity quickly as they get thinner because a larger fraction of the cell is packaging rather than active material. Fitting a 5,000 mAh battery — the same nominal capacity as many conventional flagships — into a device this thin implies meaningful gains in cell energy density and very careful internal layout. It also explains why foldable makers are so eager to adopt the most power-efficient silicon available: the Snapdragon 8 Elite Gen 5's efficiency gains matter more in a foldable than in any other phone, because there is simply less thermal mass to absorb waste heat.

What it means for buyers

The Fold8 generation signals that foldables have crossed from curiosity to mainstream flagship — but they remain premium-priced, and Canadian availability and pricing typically firm up over the weeks following launch. If you want flagship Samsung hardware today, the classic slab flagship remains outstanding value by comparison: we currently have the Samsung Galaxy S25 Ultra 256 GB in Titanium Black in stock — a 6.9-inch Dynamic AMOLED 2X QHD+ panel and 12 GB of RAM, sharing much of its display and materials DNA (including the titanium frame) with the new foldables. If your budget is closer to everyday than flagship, the Samsung Galaxy A16 5G 128 GB (in stock) brings a 6.7-inch Super AMOLED screen — the same fundamental display technology discussed above, in rigid form — to a much friendlier price point. And if the appeal of a foldable is really "a phone that becomes a tablet," a dedicated tablet still does that job better per dollar: the Galaxy Tab A9+ 11-inch (in stock) and the more powerful Galaxy Tab S10 FE (in stock) both offer more screen area than any foldable, for a fraction of the price.

Deep Dive 2 — The 4,500-Nit Race: How Tandem OLED Doubled TV Brightness

At the K-Display 2026 exhibition, which opened July 22 at Seoul's COEX, LG Display showed TV panels built on its "Tandem WOLED" architecture reaching up to 4,500 nits of peak brightness with screen reflectance below 0.3%, alongside gaming OLED panels running at up to 720 Hz and a 27-inch 5K OLED office monitor. Reporting from FlatpanelsHD confirms both LG Display's 4,500-nit 2026 TV panel and — remarkably — the same 4,500-nit figure from rival Samsung Display's 2026 QD-OLED TV panel. When the industry's two dominant OLED camps land on the same headline number in the same season, that number stops being a stunt and becomes next year's baseline.

What a nit is, and why 4,500 of them matter

A nit is one candela per square metre — a measure of luminance, the light intensity a surface emits per unit area. A typical mid-range TV manages 300–600 nits; today's best OLEDs peak between 1,500 and 3,000 nits on small highlights. The reason brightness matters so much is high dynamic range (HDR) content, which is mastered assuming displays can reproduce small, intensely bright regions — sun glinting off water, a streetlamp at night — at up to 4,000 or even 10,000 nits, per the standards used in mastering studios. A display that cannot reach those levels must "tone-map" the signal downward, compressing highlight detail. A 4,500-nit panel can display most commercially mastered HDR content essentially as the colourist saw it.

The tandem trick: stacking light-emitting layers

How do you double an OLED's brightness without burning it out? The core problem of OLED has always been that the organic emitter materials degrade as current flows through them — drive them harder and they age faster, which historically capped OLED brightness well below LCD backlights. The tandem architecture attacks this directly: instead of one organic emission stack, the panel contains two (or more) complete emission stacks in series, vertically stacked and connected by a transparent charge-generation layer. For a given brightness, each stack now needs to supply only half the light, so each runs at roughly half the current density. Because degradation accelerates non-linearly with current, halving the drive current more than doubles the emitter lifetime — or, equivalently, lets the panel run much brighter at the same lifetime. Tandem stacks were proven in automotive displays and tablets (where longevity requirements are brutal) before migrating to TVs; LG Display has now rebranded its whole TV lineup around the technique.

The second half of the announcement — reflectance under 0.3% — is arguably just as important for real living rooms. Perceived contrast is the ratio between what the screen emits and what it reflects back at you from lamps and windows. Anti-reflective coatings work by destructive interference: nanometre-thin layers are tuned so that light waves reflecting off successive layer boundaries arrive out of phase and cancel. Cutting reflectance from a typical 1–2% down to 0.3% means blacks stay black even in a sunlit room — which, for most households, does more for picture quality than the last few hundred nits.

Buying advice: brightness where it counts

Those 4,500-nit consumer panels will appear in 2026 TV ranges (LG's new G6 and C6 series were announced with upgraded tandem panels). But the underlying lesson — match brightness and coating to your room — applies to hardware you can buy today. For bright commercial spaces, lobbies and conference rooms, high sustained brightness and anti-glare treatment matter more than peak HDR numbers: our Samsung QM85C 85-inch 4K display (in stock) delivers 500 nits with a non-glare finish and is rated for 24/7 operation, while the Samsung 55-inch Crystal UHD QBC (in stock) is a superb 4K choice for meeting rooms and storefronts. On the desktop, the same physics shows up in miniature: the Samsung Odyssey Neo G7 43-inch 4K 144 Hz (in stock) uses Mini LED backlighting — thousands of tiny zones that switch off behind dark regions — to approximate OLED-like contrast with LCD brightness, and the Samsung ViewFinity S8 27-inch 4K (in stock) offers a matte anti-glare panel that tames office lighting for colour-accurate work.

Deep Dive 3 — 570 Patches, a Poisoned Extension and a Breached Auditor: Anatomy of a Bad Week in Security

This week brought one of the largest Patch Tuesdays on record and a string of breaches and supply-chain incidents. Photo: Sasun Bughdaryan / Unsplash.

Security researchers barely had time to breathe this week. Microsoft's July 2026 Patch Tuesday addressed roughly 570 vulnerabilities — one of the largest batches in the company's history — including two zero-days already being exploited in the wild: CVE-2026-56164 in SharePoint Server and CVE-2026-56155 in Active Directory Federation Services. CISA separately warned of active exploitation of a critical Adobe ColdFusion flaw (CVE-2026-48282) and urged immediate patching. Ernst & Young confirmed that an unauthorized third party accessed its IT support ticket platform between March 28 and April 12, downloading client tax and investment documents before detection. And the ModHeader browser extension — installed by 1.6 million users — was removed from the Chrome and Edge stores after researchers found dormant code capable of encrypting and uploading users' browsing history to an external server.

The science of a zero-day

A "zero-day" is a vulnerability that attackers discover and exploit before the vendor knows it exists — the vendor has had zero days to fix it. What makes the SharePoint and AD FS zero-days particularly serious is where they sit in the architecture. SharePoint servers store an organization's documents; AD FS is an identity federation service — the component that vouches for who you are across applications. Compromising an identity provider is the digital equivalent of stealing the machine that prints ID cards: the attacker doesn't need to break any other lock, because every door opens for the credentials they can now mint. This is why identity infrastructure attracts the most sophisticated attackers, and why patches for it should be applied within hours, not weeks.

The ModHeader incident illustrates a different and increasingly common threat model: the software supply chain. The extension was legitimate for years, accumulating trust and installs, before an update introduced dormant malicious code. Browser extensions are a uniquely attractive target because they run inside the browser's security context and can read the pages you visit — and because auto-update means a single compromised developer account can turn a million benign installations hostile overnight. The defensive lesson is to treat every extension as standing permission: audit what's installed, remove what you don't actively use, and prefer extensions with minimal permission requests.

Windows 10's reprieve — and what to do with it

In related news, Microsoft has quietly extended Windows 10 security support to October 2027 — a full year beyond the deadline many households were planning around — following slower-than-hoped migration to Windows 11. The extension buys time, but the direction is unchanged: older machines that cannot meet Windows 11's hardware security requirements (TPM 2.0, modern CPUs with virtualization-based security) will eventually stop receiving fixes for exactly the kinds of vulnerabilities patched this week. Hardware-backed security is not marketing: a TPM stores encryption keys in a dedicated tamper-resistant chip, and features like memory integrity use the CPU's virtualization hardware to isolate the most sensitive parts of the operating system from malware.

If your laptop is on the wrong side of that line, replacing it is a security decision as much as a performance one. The Samsung Galaxy Book 4 15.6-inch (Core i5, 512 GB) — in stock now — ships with modern hardware security out of the box, a 15.6-inch display and fast SSD storage, and makes an excellent Windows 11 machine for home or office. For strengthening your sign-ins on any computer, a hardware key is the single most effective upgrade against phishing: the Kensington VeriMark Guard USB-C fingerprint key (in stock) supports FIDO2/WebAuthn, the standard that replaces phishable passwords with cryptographic challenge-response tied to your fingerprint.
