4-inch Square TFT LCD Display - SRFA6400E-AWH-MNN - Raystar

4-inch Square TFT LCD Display 480x480 MIPI High Brightness Wide Temperature IPS (ST7701S IC)

Model No. RFA6400E-AWH-MNN

RFA6400E-AWH-MNN is a 4-inch square LCD display based on a color active matrix thin film transistor (TFT) liquid crystal display technology, using amorphous silicon TFT as the switching device. This square LCD panel features a 4-inch diagonally measured active area with 480 × 480 resolution and a 1:1 aspect ratio, making it suitable for applications requiring a display square format. The module is designed as a square TFT display for consistent image presentation in compact system layouts.

RFA6400E-AWH-MNN is an IPS transmissive square TFT that integrates the ST7701S driver IC and supports a 2-lane MIPI interface. The square LCD display provides wide viewing angles, high brightness of 1000 cd/m², and a typical contrast ratio of 800:1. This square TFT display operates within a wide temperature range from -30 to +80 °C, with the same range specified for storage.
