Product Introduction

CH12864320 128X64 FSTN Monochrome COG LCD Module: Compact Reliability for Industrial & Consumer Applications

The Chenghao Display 128x64 FSTN monochrome COG LCD module is a compact, ultra-low-power visual solution engineered for industrial and handheld applications demanding maximum efficiency and clarity. Utilizing advanced COG (Chip-on-Glass) technology, this module directly integrates the driver IC onto the glass substrate, ensuring a lightweight, exceptionally thin profile and superior long-term reliability. The FSTN technology delivers significantly higher contrast and wider viewing angles compared to standard STN displays, rendering sharp, legible text and graphics.

Supporting flexible interfaces such as SPI or I2C for streamlined system integration, the display runs efficiently on a 3.3V low operating voltage. Built to industrial-grade specifications, it performs reliably across a wide temperature range from -20°C to +70°C. It serves as an ideal choice for smart meters, portable instruments, POS terminals, and power-conscious IoT devices.

Product Features

  • FSTN Monochrome Display with Transflective Versatility
    Adopts FSTN (Film-compensated Super Twisted Nematic) technology in a positive/transflective mode, ensuring clear visibility in both bright outdoor and dim indoor environments. The 128×64 dot matrix resolution delivers sharp text, icons, and simple graphics, with a 6 o’clock viewing direction optimizing readability for frontal interaction—ideal for industrial gauges and consumer electronics.
  • Compact COG Structure for Space Efficiency
    Features a COG (Chip-On-Glass) design that integrates the driver IC directly onto the glass substrate, reducing overall thickness to 3.1mm and module dimensions to 46.0×30.0mm. This slim profile, paired with a 42.0×21.0mm viewing area, fits seamlessly into space-constrained devices like smart meters and portable sensors, minimizing installation bulk.
  • Rugged Performance Across Extreme Temperatures
    Operates reliably in temperatures ranging from -20℃ to +70℃ and withstands storage conditions of -30℃ to +80℃, ensuring durability in harsh industrial settings, outdoor enclosures, or temperature-fluctuating environments. This robust design guarantees long-term stability in diverse applications.
