How to replace the display of an iPhone 14 Pro Max
The iPhone 14 Pro Max display (OLED LTPO 120Hz with Dynamic Island and Always-On) is among the most requested premium spare parts. This guide covers disassembly, sensor transfer, and testing. Average time: 30-40 minutes. Difficulty: medium.
Warnings Before You Start
- The Face ID flex is paired to the phone: if you damage it, Face ID will never work again. Transfer it carefully to the new display.
- INCELL displays don't handle Always-On like the original OLED: inform the customer about the difference in performance.
- Always disconnect the battery before the display connectors. Do not exceed 80°C during heating.
Required Parts
Recommended Tools
- Pentalobe P2 screwdriver
- Tri-wing Y000 screwdriver

Step-by-Step Procedure
- 1
Power off and remove the pentalobe screws
Fully power off the iPhone. Remove the 2 P2 pentalobe screws on the bottom edge.
- 2
Heat the perimeter and lift the display
Heat the edges to 70-80°C for 2-3 minutes. Apply the suction cup, create a gap with a spudger, and slide it along the sides to cut the adhesive.
💡 Tip: Lift the display from the bottom, rotating it like the page of a book: the metal clips are on the top side. Never pull upward. - 3
Disconnect the battery, then the display connectors
Open to ~90°. Remove the tri-wing bracket and disconnect the battery connector FIRST. Then remove the display connector cover (Phillips #00 screws) and disconnect the touch and display flex cables.
- 4
Transfer the reusable components to the new display
Carefully remove from the old display and transfer to the new one: earpiece speaker, top sensors, and the Face ID flex (NOT cloneable, must remain the phone's original one). Follow the same assembly order.
💡 Tip: If you break the Face ID flex, Face ID will never work again on that phone. Handle it with extreme care. - 5
Connect and test the new display BEFORE closing
Connect only the display connectors (not the battery yet), power on temporarily, and check: touch across the entire surface, brightness, ProMotion 120Hz, Dynamic Island, Face ID, earpiece audio. If everything is ok, disconnect again. Verify in Settings → Display that the adaptive refresh rate is active.

Clean and apply the new perimeter adhesive
Using 99% isopropyl alcohol, remove adhesive residue from the housing. Apply the new perimeter adhesive starting from one corner, pressing firmly all along the edge.
- 7
Reassemble and test
Reconnect the display connectors, then the battery. Replace the cover and screws. Close by aligning the top clips and pressing along the perimeter for 1-2 minutes. Reinsert the pentalobe screws. Power on and perform a full round of testing.
Frequently Asked Questions
How much does an iPhone 14 Pro Max B2B display cost?
On InParts: INCELL from about €70, soft OLED from about €90-125, premium OLED (RJ) around €260, refurbished originals higher. Choose based on budget and the performance required by the customer.
With an INCELL display, do I lose Always-On and 120Hz smoothness?
Always-On and native LTPO management are guaranteed only by OLED displays. INCELL displays work but with different performance and power consumption. For a demanding customer, choose soft/hard OLED.
Do I need to program the display for True Tone?
Not for basic operation. To restore True Tone and reduce the 'non-original parts' warning, a programmer (e.g., JC/AIXUN) is required.
