The reliable way to know is your own panel code, not the model name.
Short answer: the iPhone 18 Pro Max can come with a panel from more than one maker, and the model name does not tell you which. The only way to know yours is its panel code.
No source we use lists the display suppliers of this exact model. A MacRumors report (May 2026) about iPhone 18 Pro displays names Samsung and LG; that is a single source, so treat it as likely, not confirmed.
| Code | Maker | Reported for |
|---|---|---|
| G9N | Samsung Display | iPhone 15 Pro, 16 Pro and the 17 family (OLED) |
| G9P | Samsung Display | iPhone 15 Pro, 16 Pro and the 17 family (OLED) |
| G9Q | Samsung Display | iPhone 15 Pro, 16 Pro and the 17 family (OLED) |
| GH3 | LG Display | iPhone 15 Pro Max, and the 16 and 17 series |
| GVC | LG Display | iPhone 16 and 17 series and iPhone Air |
| G9C | LG Display | iPhone 16 and 17 series |
| J5V | BOE | iPhone 16 and 17 base models |
These codes are confirmed on earlier models. No source we use confirms which codes iPhone 18 uses; a code not in the list shows as "maker not identified yet" in Panelmi.
This page does not rank makers. Panelmi shows who made the panel and does not judge quality.
Check True Tone and Night Shift first, they change the tint. Small tint differences can also exist between any two units.
Check your seller's return policy. This page does not give return advice.
Read its panel code with a sysdiagnose. The first three characters name the maker.
