3.4 Inch Industrial Square LCD Display 480×480 RGB Interface TFT Module
A 3.4-inch industrial square LCD display is a TFT module designed for embedded systems and industrial control applications requiring compact size, square aspect ratio, and stable visual performance.
This display features a 480×480 resolution with RGB 40-pin interface and 350 nits brightness, making it suitable for industrial control panels, smart devices, and embedded systems.
The square 1:1 aspect ratio provides a modern UI layout advantage, especially for industrial human-machine interfaces (HMI).
Compared with traditional rectangular LCDs, square displays allow more flexible interface design and better space utilization in compact industrial equipment.
