Montreal, July 26, 2026 — This was one of those weeks where the technology industry showed both of its faces at once. On one side, pure engineering spectacle: Samsung unveiled a folding phone thinner than most USB-C connectors, and LG Display showed OLED panels that hit brightness numbers that would have sounded like typos two years ago. On the other side, sober housekeeping: Microsoft shipped one of the largest security updates in its history, patching roughly 570 vulnerabilities in a single month. In today's edition we unpack the science behind all three stories — how a sheet of glass learns to fold, how stacking two light-emitting layers rewrites the rules of display engineering, and why the arms race between patchers and attackers keeps accelerating — and we translate each one into practical buying advice, with products you can actually get from our store today.

Today's Tech Radar

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

Deep Dive 1 — The 4.1-Millimetre Tablet: How Samsung Folded an 8-Inch Screen into a Phone

At its Galaxy Unpacked event in London on July 22, Samsung introduced the eighth generation of its folding phones: the Galaxy Z Fold8 Ultra, the Galaxy Z Fold8 and the Galaxy Z Flip8. The headline number is startling. The Fold8 Ultra measures just 4.1 millimetres thick when unfolded and weighs 215 grams, while opening into a full 8-inch main display. For perspective, that makes the opened device thinner than the USB-C port that charges it — the connector's internal receptacle alone requires close to 3.2 mm of housing. Samsung calls it the thinnest Galaxy Z Fold yet, and reviewers at the event confirmed that folded, it now feels close to an ordinary flagship slab phone.

The science: how do you fold glass?

The core problem of every foldable is a materials-science paradox. A display needs a hard, scratch-resistant front surface — which is why phones use glass — but glass is a brittle, amorphous solid that fails catastrophically under tensile stress. The solution rests on a well-understood principle of mechanics: the bending stress at the surface of a sheet is proportional to its thickness divided by the bend radius. Halve the thickness, and you halve the stress for the same curve. Make glass thin enough — the ultra-thin glass (UTG) used in folding phones is measured in tens of micrometres, thinner than a human hair — and it can bend to a radius of a few millimetres while staying below the stress at which cracks propagate. Manufacturers further strengthen it by chemical ion exchange, bathing the glass in molten potassium salt so larger potassium ions replace smaller sodium ions near the surface, creating a compressive "skin" that any crack must first fight through.

Beneath the glass sits the actual display: a flexible AMOLED. Unlike an LCD, an OLED needs no rigid backlight assembly — each pixel is its own light source, a stack of organic semiconductor layers a few hundred nanometres thick deposited on a plastic (polyimide) substrate instead of rigid glass. That is what makes folding displays possible at all. The layers of the display sandwich — polarizer, touch sensor, emitting stack, substrate — are bonded with special optically clear adhesives engineered to behave like an elastic solid, letting the layers shear microscopically against each other at the fold line instead of delaminating. Every one of those choices is invisible in a spec sheet, but they are why a modern folding screen survives hundreds of thousands of fold cycles.

The final piece is the hinge. Early foldables folded the screen flat like a piece of paper, concentrating stress along a sharp line. Modern designs sweep the display through a gentle "waterdrop" path inside the hinge cavity, keeping the bend radius large enough that the glass and OLED stack stay in their elastic comfort zone — while also letting the two halves close completely flat with no gap. Shaving the whole assembly down to 4.1 mm, as the Fold8 Ultra does, means every layer — battery, mainboard, cameras, cooling — had to be re-engineered around that hinge cavity.

Industry context

Thinness is not vanity; it is the metric that decides whether foldables go mainstream. The historic objection to folding phones was that you carried a thick, heavy "double phone" all day to enjoy a tablet occasionally. When the folded device approaches the thickness and weight of a normal flagship, that objection evaporates. It is no coincidence that the whole industry pushed in the same direction this week: the Fold8 line adopts Qualcomm's Snapdragon 8 Elite Gen 5, the Flip8 (from $1,199.99 US) gains a larger cover display with Samsung's Now Brief assistant, and the event also introduced updated Galaxy Watch models. Meanwhile the competition is not standing still — OnePlus launches its N6x on July 31 and Google unveils the Pixel 11 family on August 12.

What this means for buyers

New generations do something quietly wonderful: they make the current generation the smart buy. The Galaxy Z Fold7 — the direct predecessor announced this week's device replaces — shares the same fundamental engineering story: an 8-inch flexible folding Dynamic AMOLED 2X screen, a Snapdragon Oryon-core platform and Android 16. We currently have the Samsung Galaxy Z Fold7 512 GB in Blue Shadow and the Galaxy Z Fold7 256 GB in Silver Shadow in stock — but note stock is very limited on both, so if a foldable is on your list, this is the moment.

If what actually attracts you to a foldable is the big canvas rather than the fold itself, a thin modern tablet delivers the same 11-inch-class AMOLED-or-better experience for a fraction of the price. The Samsung Galaxy Tab S10 FE (10.9", 8 GB / 128 GB) (in stock) is built around a 4-nanometre Exynos 1580 — the same class of low-power silicon that makes thin devices possible — and the Samsung Galaxy Tab A11+ (11", 6 GB / 128 GB) (in stock) covers the family-and-media use case on a budget.

Deep Dive 2 — Tandem OLED and the 4,500-Nit Screen: Why Every Display You Buy Next Will Be Different

While Samsung was folding screens in London, LG Display spent the week in Seoul unfolding the future of the panels themselves. At K-Display 2026 (COEX, from July 22), the company showed an 83-inch OLED TV panel built on tandem technology, gaming monitors running at 540 Hz and even 720 Hz, and — the number that turned heads — Tandem WOLED television panels reaching 4,500 nits of peak brightness with under 0.3% surface reflectance. The company also rebranded its TV lineup around the architecture, now marketed as "Tandem WOLED" and "Tandem OLED." Behind those numbers sits one elegant idea worth understanding before your next TV, monitor or laptop purchase.

The science: two engines instead of one

An OLED pixel is an organic sandwich: when current flows, electrons and "holes" (missing electrons) are injected from opposite electrodes, meet in an emission layer, and release their energy as photons — light created directly at the pixel, with no backlight. This emissive nature gives OLED its famous perfect blacks: a pixel that is off emits literally nothing. But it also creates OLED's two historic weaknesses. Brightness is limited because pushing more current through the organic layers accelerates their chemical degradation — the dreaded burn-in — and blue emitter molecules, which carry the highest-energy photons, age fastest of all.

A tandem OLED stacks two complete emission units vertically within the same pixel, connected in series by a transparent charge-generation layer. The physics dividend is substantial: for the same total light output, each layer can run at roughly half the current density. Because organic degradation grows disproportionately with current, halving the drive stress more than doubles practical lifespan — or, flipped around, the panel can be driven far brighter at the same lifetime. That is how 4,500-nit OLED becomes feasible where 1,000 nits was once a ceiling. The approach was proven in professional and automotive displays, moved into tablets and laptops, and is now scaling to 83-inch television glass. Add modern anti-reflective coatings — multilayer films that cancel reflected light by destructive interference, bringing reflectance under 0.3% — and OLED's contrast advantage survives even a sunlit living room.

The refresh-rate demonstrations rely on the same emissive physics. An OLED pixel switches in microseconds, orders of magnitude faster than liquid-crystal cells that must physically rotate molecules. Feed the panel a fast enough signal and 540 Hz or 720 Hz becomes an electronics problem, not an optics problem — which is why esports-class OLED monitors are arriving so quickly.

Industry context

The market data shows this is not a laboratory curiosity. Research firm Omdia forecasts large-area OLED shipments will grow 18.8% in 2026 to 38.8 million units, powered specifically by demand for OLED monitors and laptop displays. Display makers showed ultra-slim OLED laptop panels at this year's expos, shaving thickness with thinner glass layers on both sides of the stack. Certification bodies are following: LG Display's WOLED panels earned the industry's first "100% dimming consistency" verification from UL Solutions this month. And on the quality summit, the 2026 Value Electronics TV Shootout — an annual jury evaluation by professional calibrators — crowned Samsung's 65-inch S95H OLED, confirming that the QD-OLED generation now defines reference picture quality. Competition between the two OLED camps (LG's white-OLED-plus-filter approach and Samsung's quantum-dot OLED) keeps pushing prices down while specs climb; LG's entry-level 2026 OLED TV launched in Korea around US $2,200.

What this means for buyers

The practical takeaway is a two-track strategy. If you buy premium, you are buying into the tandem/QD-OLED era and the value keeps improving each cycle. But the same OLED gold rush is compressing the price of excellent LCD technology — and for many real-world uses, a bright, calibrated 4K LCD remains the rational choice, especially where burn-in risk from static content (spreadsheets, signage, dashboards) matters. From our current inventory: the Samsung ViewFinity S8 32" 4K UHD monitor (in stock) is a factory-calibrated productivity panel ideal for photo and document work; the Samsung 55" Crystal UHD Signage QBC (in stock) brings 4K to lobbies, meeting rooms and storefronts with a 16/7 duty rating; and for large venues the Samsung QM85C 85" UHD display (in stock) offers 500-nit non-glare output rated for 24/7 operation — an application where LCD's immunity to static-image aging is precisely the right engineering trade-off.

Deep Dive 3 — 570 Fixes in One Day: The Anatomy of a Record Patch Tuesday

On the second Tuesday of July, Microsoft shipped fixes for roughly 570 vulnerabilities across Windows and its server products — one of the largest Patch Tuesdays on record — including three zero-day flaws, with actively exploited bugs in SharePoint Server (CVE-2026-56164) and Active Directory Federation Services (CVE-2026-56155). The same week, CISA escalated a maximum-severity CVSS 10.0 authentication bypass in the SimpleHelp remote-support tool (CVE-2026-48558), Ernst & Young confirmed attackers spent two weeks in spring quietly downloading client documents from an IT support ticket platform, the ShinyHunters group hit Abbott Laboratories through voice phishing of employees, and a browser extension with 1.6 million installs, ModHeader, was pulled from the Chrome and Edge stores after researchers found dormant code capable of encrypting and exfiltrating users' browsing history. A dense week — and an unusually instructive one, because these incidents illustrate every layer of how modern attacks actually work.

The science: why software can't simply be built without holes

A vulnerability is a gap between what a program is specified to do and what it actually does under adversarial input. The mathematics is humbling: a modern operating system contains tens of millions of lines of code, and the number of possible execution paths grows combinatorially with program size — no amount of testing can explore them all, and formal proof of correctness at OS scale remains beyond practical reach. So security becomes a discovery race. When defenders (or vendors) find a flaw first, it gets a CVE identifier and a patch. When attackers find it first, it is a zero-day — defenders have had zero days to prepare — and it gets exploited until discovered. A number like 570 fixes in one month is therefore not evidence that software is getting worse; it partly reflects the enormous, still-growing surface area of code, and partly a defensive machine (bug bounties, automated fuzzing, internal red teams) that is finding flaws faster than ever. The metric that matters is the handful under active exploitation — this month, flaws in exactly the identity and collaboration systems (ADFS, SharePoint) that sit at the heart of corporate networks.

The week's breaches complete the picture, because most real intrusions no longer start with exotic exploits. The EY incident targeted a help-desk platform — attackers love ticket systems because they concentrate credentials and trust. The Abbott attack used vishing, voice phishing: calling employees and talking them into granting access, an attack on human trust rather than code. And ModHeader was a supply-chain play: compromise one trusted component and you inherit its 1.6 million users. Defence therefore has to be layered — patching closes the code layer, hardware-backed authentication closes the human layer, and cautious software sourcing closes the supply-chain layer.

Practical protection, at home and at work

The good news is that the highest-value defences are cheap and mostly automatic. First: turn on automatic updates everywhere — the JulyPatch Tuesday only protects machines that install it, and attackers begin reverse-engineering patches into exploits within days of release. Second: retire hardware that no longer receives updates; an unpatched device on your network is a door that can never be locked. If your PC predates the current security baseline — TPM 2.0 hardware cryptography, virtualization-based security, an OS still in support — replacement is a security decision as much as a performance one. Two in-stock options we recommend: the HP EliteBook 6 G1a 14" Copilot+ PC (AMD Ryzen AI 5 340, 16 GB / 512 GB), a business-class machine whose on-chip NPU also happens to place it in the modern AI-PC category discussed in this week's radar, and the Lenovo ThinkPad E16 Gen 3 (Intel Core Ultra 7 255H, 16 GB / 512 GB), both current-generation platforms with years of update runway ahead. Third: move your most important accounts to phishing-resistant authentication. A FIDO2 hardware key such as the Kensington VeriMark Guard USB-C fingerprint key (in stock) performs a cryptographic handshake that simply fails on a fake login page — the mathematical countermeasure to the social attacks that hit EY and Abbott.

For businesses, the calculus is stricter: an inventory of every device and its patch status, retirement schedules for out-of-support systems, and hardware keys for anyone with administrative access.
