The first Chinese foldable to use glass instead of plastic
In late 2021, OPPO's debut foldable phone quietly revealed something larger than a product launch: a Chinese manufacturer turning to its most formidable rival for the very screen that would define the device. By choosing Samsung Display's Ultra-Thin Glass technology for the Find N, OPPO acknowledged both the maturity of Samsung's foldable expertise and the industry's convergence around a shared standard — one that Samsung, paradoxically, profits from even as competitors rise to challenge it.
- OPPO's Find N arrives as the first Chinese foldable to use Samsung's UTG glass, breaking from the polyimide film that had quietly limited every previous attempt by Chinese makers.
- The 7.1-inch LTPO OLED main display with 120Hz refresh rate signals that OPPO is no longer willing to compete on compromise — it wants parity with the category's leader, built from the leader's own components.
- Samsung Display's willingness to supply a direct competitor suggests its manufacturing capacity has grown large enough that feeding rivals is more profitable than guarding exclusivity.
- Xiaomi is reportedly circling Samsung's 8.01-inch foldable panel, and if multiple Chinese brands adopt the same display stack, Samsung's dominance shifts from device maker to indispensable infrastructure.
- The foldable market remains expensive and nascent, but the Find N's launch marks the moment the industry stopped debating materials and started competing on execution.
When OPPO prepared to launch the Find N in December 2021, the decision that mattered most wasn't the design or the price — it was the screen. OPPO had gone to Samsung Display for a 7.1-inch LTPO OLED panel built with Ultra-Thin Glass, a proprietary protective layer that Samsung had developed to replace the polyimide film standard in earlier foldables. Glass was harder, more scratch-resistant, and closer in feel to what consumers expected from a premium phone. The Find N would be the first Chinese foldable to use it.
The secondary cover display, measuring 5.45 inches, came from BOE — a domestic Chinese supplier — while the main panel's 120Hz adaptive refresh rate offered both smoothness and battery efficiency. But the UTG layer was the headline. Polyimide had worked well enough, but it always felt like a concession. Samsung had moved past it in its own Galaxy Z devices, and now it was willing to bring that same technology to a competitor.
That willingness said something important. Samsung Display's manufacturing capacity had grown to the point where supplying rivals was a strategic advantage, not a vulnerability. The company could remain central to the foldable category regardless of which brand's logo appeared on the outside of the device.
The implications stretched beyond OPPO. Xiaomi was reportedly considering Samsung's 8.01-inch foldable panel for its own upcoming flagship. If Chinese manufacturers began adopting Samsung's display technology at scale, the foldable market would transform from Samsung's private territory into a genuine competitive arena — one where Samsung still collected a toll at the gate. For consumers, the Find N represented something real: a foldable built to the same material standard as the category's best, arriving at a moment when the industry had finally agreed on what that standard should be.
OPPO was about to unveil its first foldable phone, the Find N, and the company had made a choice that said something about where the Chinese smartphone industry stood in late 2021: it went to Samsung for the screen. Not just any screen—a foldable display built with Samsung Display's proprietary Ultra-Thin Glass, or UTG, a protective layer that represented a meaningful step forward in how these devices could be made.
The Find N's main display measured 7.1 inches diagonally, an LTPO OLED panel capable of shifting its refresh rate up to 120Hz depending on what was on screen. That flexibility mattered for battery life and smoothness. But the real story was the UTG layer sitting on top of it. Samsung had developed this glass-based protection to replace the polyimide film that had been the standard in foldable phones up to that point. Glass was harder, more resistant to scratches and impacts, and it felt more like the glass you'd find on a regular phone. The Find N's secondary display, the one you'd see when the phone was folded shut, came from BOE, a Chinese manufacturer, and measured 5.45 inches with its own OLED panel, likely protected by Corning's Gorilla Glass.
What made this moment significant was that OPPO's Find N would be the first Chinese foldable to use UTG technology. Previous foldables from Chinese makers had relied on polyimide, a plastic-like material that worked but felt like a compromise. Samsung had been using UTG in its own Galaxy Z folds for a while, but now the company was willing to supply the technology to a competitor. That willingness suggested something about Samsung Display's confidence in its manufacturing capacity and its position in the supply chain—it could afford to sell to rivals because demand was outpacing what any single phone maker could absorb.
The timing mattered too. Xiaomi was reportedly eyeing Samsung Display's 8.01-inch foldable panel and UTG protection for its own upcoming flagship. If that happened, if multiple Chinese manufacturers started adopting Samsung's display technology and protection methods, the foldable phone market would begin to look less like Samsung's exclusive domain and more like a genuine competitive space. The Find N's December 2021 launch was positioned as a turning point—not because OPPO had invented something new, but because it was adopting the best available technology and bringing it to a market that had been waiting for something better than what polyimide could offer.
The question hanging over the moment was whether this would actually change anything. Samsung had dominated foldables since the beginning, and supplying the screens to competitors was a way of staying central to the category even if other companies' phones gained market share. But for consumers in China and elsewhere, the Find N represented a real alternative, built with materials and technology that matched what Samsung was putting in its own devices. The foldable phone market was still young, still expensive, still finding its shape. OPPO's choice to use Samsung's display technology was a sign that the industry had settled on what worked—and that Samsung, at least for now, was the company that knew how to make it.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that Samsung is making OPPO's foldable screen? Couldn't OPPO just make their own?
The display is the hardest part of a foldable phone. You're bending glass and electronics repeatedly, and that breaks things. Samsung spent years figuring out how to make a screen that survives that. OPPO could try to build one from scratch, but they'd be years behind.
So this is really about Samsung's UTG technology—the glass layer instead of plastic?
Exactly. Polyimide film works, but it scratches easily and feels cheap. UTG is actual glass, harder and more durable. It's the difference between a phone that feels like a real device and one that feels like a prototype.
If Samsung is supplying screens to OPPO, isn't Samsung helping its own competition?
Yes, but Samsung Display is a separate business unit. They make money selling screens. And they're so far ahead in foldable display manufacturing that they can afford to supply competitors. It's actually a way of staying central to the market.
What does this mean for other Chinese phone makers?
It opens the door. If Xiaomi and others can buy Samsung's foldable displays and UTG protection, they can build competitive foldables without inventing the technology themselves. The barrier to entry just got lower.
Does this threaten Samsung's foldable phone business?
Potentially, but not immediately. Samsung's still ahead on design, software, and brand. But yes, if Chinese makers can offer similar hardware at lower prices, that's a real threat over time.
