AM-640480G4TNQW-A0H AMPIRE 5.7" TFT-LCD screen 640*480 Display

Product Overview

The AM-640480G4TNQW-A0H is a 5.7-inch a-Si TFT-LCD display module manufactured by Ampire Co., Ltd., a leading Taiwan-based specialist in industrial TFT LCD displays with over 25 years of experience. This 5.7" VGA (640×480) TFT panel features TN (Twisted Nematic) technology with WLED backlight, delivering 500 cd/m² brightness and a 250:1 contrast ratio — making it ideal for industrial HMI, medical devices, test equipment, and embedded display applications.

Ampire is renowned in the TFT display industry for producing highly reliable, long-life display modules with extensive product lines covering sizes from 2.2" to 21.5". Many Ampire displays offer extended temperature range versions, high-brightness options, wide viewing angle technologies (IPS/MVA), and long-life backlight solutions — making them a preferred choice for demanding industrial environments worldwide.

Technical Specifications

Signal Interface Note: LVDS vs. Parallel RGB

The AM-640480G4TNQW-A0H uses an LVDS (Low-Voltage Differential Signaling) interface with 1 channel and 6-bit color depth, connected via a 20-pin FPC (Flexible Printed Circuit) connector. The LVDS interface provides superior electromagnetic interference (EMI) performance compared to parallel RGB, making it better suited for industrial environments with electrical noise. If TTL/Parallel RGB input is required, an external AD board (signal converter) can be added to accept standard VGA or TTL input signals.

Typical Applications

• Industrial HMI: Human-machine interfaces for PLC-based automation equipment, CNC machines, and industrial control panels

• Medical Devices: Patient monitoring equipment, diagnostic displays, and portable medical instruments requiring reliable industrial-grade screens

• Test & Measurement: Oscilloscope displays, signal analyzers, power meter interfaces, and laboratory equipment

• Embedded Systems: Single-board computers (Raspberry Pi, BeagleBone), retro gaming kits, and DIY electronics projects

• Transportation: Vehicle dashboards, GPS navigation units, and maritime electronics

• Point-of-Sale (POS): Commercial terminal displays and receipt printer interfaces
