The P20 and P20 Pro use different displays: the P20 is LCD, while the P20 Pro is OLED. A Huawei P20 screen replacement is a simple flat LCD job, while the P20 Pro is an OLED repair that needs more care with the notch assembly. 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 P20 model do you have, and which panel fits it?
The P20 uses a 5.8-inch LCD panel, while the P20 Pro uses a 6.1-inch OLED panel with a notch. The two models share no screen parts, so confirm the exact model before ordering.
| Model | Display | Repair note |
|---|---|---|
| P20 | 5.8″ LCD | Simple flat LCD repair |
| P20 Pro | 6.1″ OLED | Notch assembly, more care |
The P20 Pro’s OLED is the higher-value repair, and the notch houses the front camera and sensors that must transfer cleanly. Match the panel to the exact model.
Common P20 and P20 Pro screen faults
The most common faults are cracked glass, lines or blotches after a drop, touch failure, and burn-in on the OLED Pro model. The Pro panel is prone to burn-in after heavy use.
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 the P20, a dim screen with a faint image usually means an LCD backlight fault.
P20 screen repair differences
The P20 is a straightforward LCD repair, while the P20 Pro is an OLED job with a notch assembly. The opening sequence is similar, but the Pro’s panel is thinner and the notch transfer is the highest-risk step.
Because these phones are older, match the repair price to the phone’s current value and check the battery with the quote. The screen grades guide explains the grade options for OLED and LCD panels.
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 P20 pair is another two-in-one name: LCD on the standard model and OLED on the Pro. Confirm the model first, transfer the notch assembly carefully on the Pro, and check the battery with the quote, because these phones are old enough that owners often need both services.

Conclusion
The P20 and P20 Pro are different repairs: a flat LCD job and an OLED job with a notch transfer. Match the panel to the exact model, test the notch functions on the Pro, and check the battery with the quote. Shops can order P20 series screens from Digi4u.
Frequently Asked Questions
Does the P20 Pro use an OLED screen?
Yes. The P20 Pro uses a 6.1-inch OLED panel, while the standard P20 uses a 5.8-inch LCD.
Can I use a P20 screen on a P20 Pro?
No. The two models use different panel types, sizes and connectors, so the parts are not interchangeable.
Why is my P20 Pro screen showing ghost images?
Ghost images on a grey screen are OLED burn-in, a normal ageing effect. A replacement with a burn-in-tested panel avoids it.
