iPhone screen panel codes

Which company made the panel, by the first three characters of the panel serial number.

Short answer: the first three characters of the panel serial number in an iPhone's diagnostic file name the panel maker. Match all three, not only the first letter: G starts codes of both Samsung Display and LG Display.

Confirmed codes

Confirmed means at least two independent sources, or a real diagnostic archive plus a source.

Code	Maker	Reported for	Confidence
G9N	Samsung Display	iPhone 15 Pro, 16 Pro and the 17 family (OLED)	confirmed
G9P	Samsung Display	iPhone 15 Pro, 16 Pro and the 17 family (OLED)	confirmed
G9Q	Samsung Display	iPhone 15 Pro, 16 Pro and the 17 family (OLED)	confirmed
GH3	LG Display	iPhone 15 Pro Max, and the 16 and 17 series	confirmed
GVC	LG Display	iPhone 16 and 17 series and iPhone Air	confirmed
GVH	LG Display	iPhone 16 Pro	confirmed
G9C	LG Display	iPhone 16 and 17 series	confirmed
J5V	BOE	iPhone 16 and 17 base models	confirmed

Likely, from one source

These come from a single source each, so treat them as likely, not confirmed.

GV3: likely LG Display. One page lists it; it may be a typo of GH3.
JDV: one page lists it as BOE, but it conflicts with J5V. Treated as unreliable.
Older LCD iPhones (6 to 11): DTP and C3F are likely LG Display; DKH and COV are likely Sharp; FVQ and F7C are likely Toshiba. Sources for these agree only with each other.

No source we found lists codes for other makers of iPhone panels.

How to read yours

Create a sysdiagnose (how to share an iPhone sysdiagnose) and open it in Panelmi. This page does not say one maker is better than another.

Which panel codes are confirmed?

G9N, G9P and G9Q are listed as Samsung Display; GH3, GVC, GVH and G9C as LG Display; J5V as BOE.

Why does the first letter not decide the maker?

Both Samsung Display and LG Display codes start with G, so all three characters must match.

Is one maker better than another?

This page does not rank makers. Codes only name who made the panel.
