Two repairs can cost £40 apart and look identical on the counter. The difference is the panel, and almost nobody explains it. Here is the whole thing — substrate, brightness, thickness, True Tone — including where the cheap option is genuinely the right call.
Every iPhone from the X onwards left the factory with an OLED panel built on a flexible plastic substrate. When you replace that screen you have three realistic choices: a soft OLED, which is built the same way; a hard OLED, which is the same display technology on a rigid glass base; or an incell LCD, which is a different display technology altogether, wearing your phone's frame.
We fit soft OLED as standard, from MobileSentrix. Most cheap repairs fit incell. Both carry a warranty and both work. They are not the same thing, and you should be told which one you're getting before it goes in — not after.
| Grade | Substrate | Display quality | Build | True Tone | Rough wholesale cost |
|---|---|---|---|---|---|
| Genuine service part On request |
Original Apple panel | Reference — it is the original | Factory spec | Native | Highest |
| Soft OLED (XO7) What we fit as standard |
Flexible polyimide — same construction family as the factory panel | Industry grading puts it at roughly 90–95% of original | Thinner assembly, sits flush, tolerates chassis flex | Supported via data transfer from the old panel | Mid–high |
| Hard OLED | Rigid glass | Good OLED colour and true blacks | Slightly thicker, less tolerant of housing flex | Supported via data transfer | Mid |
| Incell LCD What most cheap repairs use |
LCD with backlight — not OLED at all | No true blacks, lower peak brightness, washes out in sunlight | Functional, warrantied | Varies by batch | Lowest — often a third or less of soft OLED |
Grade characteristics and the 90–95% figure are from published repair-industry grading guides (see sources at the foot of this page). Wholesale cost bands are indicative and move constantly with model and supply.
Specifics beat adjectives, so here is exactly what we buy. Our soft OLED panels are XO7, MobileSentrix's own screen line, listed on their catalogue as "Aftermarket Pro: XO7 Soft". We source through their UK arm.
Four things about XO7 that matter to you rather than to us:
What that last one means for you, precisely: your warranty is with us — 12 months on parts and labour. The supplier's lifetime cover is why we can replace a failed panel without arguing about it, because it costs us nothing to do the right thing. A shop buying unbranded stock with no supplier backing is paying out of its own pocket every time, which is exactly when warranty claims start getting difficult.
This is the bit that gets skipped. Your iPhone's original OLED is built on polyimide — a flexible plastic film. That matters for three practical reasons:
Soft OLED is not a marketing tier. It is a description of how the panel is physically built — the same construction family as the one that came out of the factory.
Where we'll argue against ourselves: construction type alone does not determine brightness, colour accuracy or pixel uniformity. A well-made hard OLED can measurably outperform a poorly made soft OLED. "Soft OLED" on an invoice is not automatically a guarantee — the manufacturer and the batch matter just as much as the category. Anyone telling you the label alone settles it is selling, not explaining.
We're not going to pretend incell is worthless. It works, we fit it on request, and it carries the same 12-month warranty. On a five-year-old handset that has stopped getting security updates, spending soft OLED money is a poor decision and we'll say so.
But you should know what changes, because it is not subtle once you've seen it:
OLED pixels switch off individually. An LCD backlight is always on behind the panel, so black is dark grey. Most obvious at night and in dark mode.
Lower peak brightness. In direct Windsor sunshine on the Long Walk, the difference is immediate.
Whites often read cooler or warmer than the original, which you notice most when comparing against another phone.
Support varies by batch on incell. On soft and hard OLED it can be transferred from the old panel.
OLED draws less on dark content because black pixels are off. An LCD backlight doesn't care what's on screen.
Anyone buying a used handset checks the screen first. A visibly non-original display is a negotiating point against you.
Tell us the model and what's broken. We'll quote the soft OLED, the budget option and the genuine part side by side, and tell you which we'd pick if it were ours.
Already had a repair somewhere and wondering? Four tests, no tools:
None of this means you were cheated — a budget panel honestly sold at a budget price is a fair deal. It means you should know what's in there, and what to ask for next time.
An aftermarket panel built on flexible polyimide — the same construction family as the factory Apple panel. Thinner, sits flush, tolerates chassis flex. Industry grading puts it at roughly 90–95% of original display quality. It's what we fit as standard on OLED iPhones, from MobileSentrix.
The substrate. Soft is flexible polyimide like the original; hard is rigid glass, slightly thicker and less flex-tolerant. Hard OLED is cheaper and its rigid build resists some pressure well. Category alone doesn't decide brightness or colour — a good hard OLED beats a bad soft OLED — but at equal quality, soft is the closer match to factory.
It's LCD technology in an OLED phone's body. Backlight instead of self-lit pixels, so no true blacks, lower peak brightness, washes out in sun. Often a third or less of soft OLED at wholesale — which is exactly why cheap repairs default to it.
It depends on calibration data stored on the original panel, which can be transferred across with a programmer. Soft and hard OLED support this. Whether it works on your model depends on the handset and the condition of the old display — we check and tell you before, not after.
Soft OLED from MobileSentrix on OLED iPhones. Genuine Apple and Samsung service parts on request, ordered in. Incell as an explicit budget choice, named and priced up front — usually on older handsets where it's the sensible call. Same 12-month warranty on every tier.
XO7 soft OLED, MobileSentrix's own line, listed as "Aftermarket Pro: XO7 Soft", sourced through their UK arm. Genuine XO7 panels are engraved "XO7" on the flex cable so you can verify it. They ship with the steel plate pre-installed and fresh water-seal adhesive, and XO7 2.0 carries a lifetime supplier warranty covering flex, digitizer, frame separation and panel failure.
