128×64 STN Yellow-Green Positive Transmissive LCD Module (3.0 V Operation)

This 128×64 dot-matrix monochrome LCD module is designed with STN yellow-green positive transmissive technology, delivering high contrast and clear visibility for compact embedded devices and industrial applications. 

Operating at a low 3.0 V supply, it is ideal for portable, battery-powered equipment requiring low power consumption and stable visual performance. Its wide temperature tolerance (–10 °C to 60 °C) and robust mechanical structure ensure dependable operation in demanding environments. 

With a viewing direction of 6 o’clock and a 1/64 duty, 1/9 bias driving scheme, the display provides stable contrast and uniformity. The module supports an 8080-type parallel interface via a 17-pin connector, making it easy to integrate into various control systems.
