What this guide covers

The laptop model name is useful, but the screen part number is the safest way to match a replacement panel.

Look for the code on the rear sticker of the removed panel, then confirm size, resolution, connector pin count, connector position, and mounting type.

If the screen is still inside the laptop, share the laptop model plus photos of the old panel before ordering.

Start with the panel sticker

Most laptop screens have a manufacturer label on the back of the panel. This label can include the screen model number, panel code, part number, revision, and barcodes.

Common panel codes start with patterns like B156, N156, NV156, LP156, LTN156, or NT156. The exact code matters because two laptops with the same outer model can ship with different panels.

  • Remove the bezel carefully and photograph the full rear sticker.
  • Capture the connector area so the pin count and connector side are visible.
  • Note screen size, resolution, refresh rate, and whether brackets are attached.
  • Keep the laptop model number ready as a backup compatibility clue.

Do not rely only on laptop model names

A laptop model such as Dell G5 15, Lenovo Legion, or HP Pavilion can have multiple display options. One variant may use HD, another Full HD IPS, another high refresh, and another touch panel.

Use the laptop model to narrow the search, then verify the actual panel code and connector before payment. This avoids buying a screen that fits the lid but not the cable or motherboard.

What to send before ordering

For a reliable match, send the screen part number, laptop model, old screen photos, and the preferred screen type. If the old display is cracked but readable, also note the current resolution shown in Windows display settings.

LapKart display products include compatibility notes, specifications, and a 6-month replacement warranty, but the best result still depends on matching the old panel correctly.

Questions customers ask

Where is the laptop screen part number printed?

It is usually printed on a sticker on the back of the LCD/LED panel. You normally need to remove the front bezel and loosen the panel to see it.

Can I order using only my laptop model?

Sometimes, but it is less reliable. Many laptop models ship with multiple screen options, so the panel code and connector details are safer.

What photos should I send to check compatibility?

Send the rear sticker, connector area, full old panel, laptop model label, and any bracket/mounting points.
