The P40 and P40 Pro are Huawei’s OLED flagships: the P40 uses a flat OLED panel, while the P40 Pro uses a curved OLED with a punch-hole camera. A Huawei P40 screen replacement is a careful OLED job, and the Pro’s curved panel demands the most skill. Digi4u stocks tested screens for both models.

About this guide: based on hands-on bench testing and repair experience; confirm model specifications with the supplier before ordering.
Which P40 model do you have, and which panel fits it?
The P40 uses a 6.1-inch flat OLED panel, while the P40 Pro uses a 6.58-inch curved OLED panel. Both use punch-hole front cameras, and the panels are not interchangeable.
| Model | Display | Repair note |
|---|---|---|
| P40 | 6.1″ OLED, flat | Flat OLED, standard fitting |
| P40 Pro | 6.58″ OLED, curved | Curved panel, higher fitting risk |
Confirm the exact model before ordering, because the flat and curved panels are completely different parts. The P40 Pro’s curved panel is thin and fragile along the edges.
Common P40 and P40 Pro screen faults
The most common faults are cracked glass, lines or blotches after a drop, touch failure, and burn-in on heavily used panels. The curved Pro panel cracks at the edges, while the flat P40 cracks at the corners.
Lines and blotches point to panel damage, while burn-in shows as ghost images on grey screens. Test in safe mode and rule out water damage before ordering. On both models, the punch-hole camera sits in the panel, so the front camera must transfer cleanly.
P40 screen repair differences
The P40 and P40 Pro are OLED repairs with a punch-hole camera, and the Pro’s curved panel is the high-risk step. The front camera and earpiece sit in the top of the screen assembly and must transfer cleanly.
On the Pro, the curved panel must seat evenly to avoid light bleed along the edges. Because these are older flagships, match the repair price to the phone’s current value and check the battery with the quote. The screen grades guide explains the OLED grade options.
Post-repair testing checklist
Test the display, touch, the fingerprint sensor, the cameras, the proximity sensor and charging while the phone is open, and check the battery health before sealing. The full test sequence is listed in the screen repair tools and preparation guide.
The standard process
The standard screen replacement opens from the rear: isolate the battery first, release the assembly, fit the new part and test before resealing.
The full tool list is in the screen repair tools and preparation guide, and the opening technique is covered in the safe phone opening guide. The model-specific risks for this phone are covered above.
Digi4u workshop notes
The P40 pair shows the two sides of OLED repair: the flat P40 is straightforward, and the curved Pro is where the skill shows. Our rule is the same for both ¡ª transfer the punch-hole camera carefully, seat the curve evenly, and test before sealing. Check the battery with the quote, because owners of these phones often need both.

Conclusion
The P40 and P40 Pro are careful OLED repairs with a punch-hole camera to transfer, and the Pro’s curved panel is the high-risk step. Match the panel to the exact model, test the camera and the curves, and check the battery with the quote. Shops can order P40 series screens from Digi4u.
Frequently Asked Questions
Does the P40 Pro use a curved screen?
Yes. The P40 Pro uses a curved OLED panel, while the standard P40 uses a flat OLED panel.
Can I use a P40 screen on a P40 Pro?
No. The two models use different panel sizes and curves, so the parts are not interchangeable.
Why is my P40 screen showing burn-in?
Burn-in is a normal ageing effect on OLED panels and appears as ghost images on grey screens. A replacement with a burn-in-tested panel avoids it.
