1. Classic Standard 128×64 Dot Matrix, Low Development & Debugging Difficulty

The JGS12864W3201 adopts widely recognized 128×64 monochrome dot matrix specification, complete with abundant driver demo codes and Chinese font libraries. It can be driven by ordinary MCUs to fully display numbers, curves and Chinese prompts, greatly shortening instrument R&D cycle.

2. 3.1 Inch Compact Body, Easy Installation for Narrow Devices

The whole module features compact 93×70mm outline with two thickness options (11.6mm / 13mm) to fit different equipment inner spaces. Narrow-bezel view window with standard mounting holes allows direct embedded assembly for handheld and cabinet-mounted small instruments.

3. Low Power STN LCD, Stable 7×24 Hours Continuous Operation

Adopts mature STN monochrome LCD craft with zero ghost image and flicker on static screens and low overall power consumption. Industrial anti-aging LCD raw materials prevent yellow background and pixel decay after long-term power-on in workshop environments.

4. Universal 20PIN 5V Interface, Direct Replacement for Legacy Equipment

Unified pin definition of 20PIN pin header matched with standard 5V power supply. Most old PLC and temperature control testers can be replaced directly without circuit board redesign, lowering after-sales maintenance and mass assembly costs.

5. -20~70℃ Wide Temperature Resistance, Durable Under Complex Working Conditions

Operating range covers -20℃ low temperature to 70℃ high temperature, storage tolerance from -30℃ to 80℃. It rarely suffers screen flicker or dim display after long power-on in northern winter workshops and high-temperature control cabinets, cutting equipment after-sales failure rate.

6. Universal Compatibility for Multiple Types of Small Industrial Equipment

Industrial Control & PLC Equipment

Small PLC operation panels, temperature & humidity transmitters, power monitoring instruments.

Medical Testing Instruments

Portable physical examination devices, laboratory testing display terminals.

Physical & Chemical Precision Testers

Water & gas analyzers, power supply testing instruments.

Small Embedded Terminals

Handheld measuring equipment, miniature temperature controllers, security status display screens.
