Laptop Screens: LVDS vs eDP, Resolution, Form Factor

A Screen "Fits by Size" — That's a Myth

Diagonal (13.3", 14", 15.6") is only one of four parameters, and the least reliable. A screen of the same diagonal from different manufacturers or even different revisions of the same laptop may have:

• Different cable types — LVDS (older standard, thick flat cable, 30-40 pins) or eDP (thinner, fewer pins, newer models) — they are physically incompatible
• Different resolutions — HD (1366×768), Full HD (1920×1080), or higher
• Matte or glossy
• Touch or non-touch — touchscreens have an additional cable for the touchscreen controller

How to Check the Exact Screen Model

The most reliable source is the marking on the back of the screen itself (a model like N140HCE-EAA or similar). This is the actual identifier for compatibility search.

Why the Cable is a Separate Part from the Screen

The cable (flex) connecting the screen to the board often changes within the same laptop model between revisions — so the screen and cable sometimes need to be ordered separately.

Typical Customer Mistakes

• "The diagonal is the same — so it will fit" — the diagonal says nothing about the cable type or resolution.
• "I'll buy a cheaper screen with a different cable type, I'll resolder it" — LVDS and eDP are not compatible at the controller level.
• "The main thing is that an image appears at all" — a screen with an unsuitable resolution can technically show a distorted image — this is not a "working" solution.

How to Choose a Screen from Us

Most accurately — send the marking from the back of your old screen or the exact model and configuration of your laptop.
