Before you can order a replacement laptop screen, you need to know exactly which panel your laptop uses. Two laptops that look identical on the outside can ship with completely different screens — different connectors, resolutions, or mounting. This guide shows you the reliable ways to find your laptop screen’s model number so you order the right panel the first time.
Method 1: Read the label on the back of the panel (most reliable)
Most laptop LCD panels have a label on the back with the full model code, for example NV156FHM-N48, B156HAN02.5 or LP156WFC-SPD1. The full panel model and hardware revision are the strongest starting point for finding a compatible replacement.
To read it you usually have to remove the screen bezel and detach the panel. If you are comfortable opening the lid, record the complete code, revision and connector photo. Do not rely on the base code alone: connector position, mounting, firmware, touch construction and other details can still differ. If you cannot open the lid, use one of the methods below first and confirm the final specification before ordering.
Method 2: Use the panel model number
The code identifies a panel family and variant, but it is not a universal specification decoder. Using NV156FHM-N48 as an example:
- NV156FHM — a BOE 15.6-inch Full HD panel family
- N48 — the specific variant suffix
Within BOE naming, size and resolution families often follow patterns such as 156 for 15.6-inch and FHM for Full HD. These conventions are manufacturer-specific and the suffix must be looked up using the complete model and revision; do not infer refresh rate, pin count or connector position from a few characters alone.
Method 3: Look up your laptop model
If you can’t open the lid, start from the laptop’s full model number — not just the marketing name. “Lenovo IdeaPad 3” or “ASUS VivoBook 15” is not enough; you need the full model such as 15IIL05 or X512DA, usually printed on the bottom case or in the BIOS.
One laptop family often shipped with several different panels over its production run, so a laptop model gives you a shortlist rather than a single answer. That is why you should confirm every specification group below before buying. You can use our compatibility lookup to cross-check your laptop or panel code against the panels we stock.
The specifications you must confirm
A replacement is safe to order only after the complete mechanical and electrical specification has been checked:
| Specification | Why it matters |
|---|---|
| Size & resolution | Diagonal size, pixel count and aspect ratio must suit the laptop |
| Interface & pinout | eDP/LVDS, pin count, lane configuration and cable wiring must match |
| Refresh rate | The panel, cable, motherboard and firmware must support it |
| Connector position | The cable must reach without twisting or strain |
| Dimensions & mounting | Outline size, thickness, brackets and adhesive layout must fit the lid |
| Touch & revision | Confirm whether the part is a bare LCD or complete touch assembly, plus the full hardware revision |
