Exact replacement panel

The ATPAZDB B156ZAN03.1 is a 15.6 inch UHD 4K display panel built as a direct replacement for the original B156ZAN03.1 screen. It delivers a native resolution of 3840x2160 through a 40 pin video signal connector and operates at a 60Hz refresh rate.

Owners of compatible 15.6 inch UHD laptops

This panel suits owners of a laptop that originally shipped with the B156ZAN03.1 part number and a 40 pin UHD 4K display. It is not suitable for machines that use a different pin count, a lower resolution panel, a touch digitiser layer, or a high refresh rate screen.

40 pin UHD 4K connector

The single specification that determines fit is the 40 pin video signal connector combined with the 3840x2160 resolution. Verify the original panel part number and pin layout before ordering; a mismatched connector or resolution will prevent installation.

Questions about this item

Will the 40-pin connector on the B156ZAN03.1 need replacement during the laptop's lifespan?

The 40-pin video signal connector is a fixed part of the panel and is not designed for separate servicing or replacement.

What limit appears first when the 3840x2160 panel runs continuously at 60Hz?

The 60Hz refresh rate caps motion smoothness, so fast-moving content will show the panel's temporal limit before brightness or contrast degrade.

How much heat and power does the 400 cd/m² backlight generate during all-day use?

At 400 cd/m² brightness the backlight draws its rated power and produces typical LCD panel warmth; no active cooling is required.
