3.2 Inch 128×64 STN Blue Negative Transmissive LCD Module

The HSM12864A is a 128×64 dot-matrix monochrome LCD module built with STN Blue Negative Transmissive technology, offering sharp, high-contrast white characters against a deep blue background. This display is optimized for professional devices requiring clear graphical output in a compact form factor. With a 5.0 V operating voltage, 0107/0108 driver ICs, and stable 1/64 duty, 1/9 bias driving scheme, the module delivers consistent performance suitable for industrial control panels, handheld instruments, and embedded systems. The wide operating temperature range of –20 °C to 70 °C, along with a robust metal frame construction, ensures long-term durability even in demanding environments. A bright white LED backlight (I = 80 mA) provides excellent visibility under various lighting conditions.
