Monochrome dot matrix LCDs in STN and FSTN types, with a resolution of 128×64 or higher, capable of displaying graphics and multiple lines of text. They are widely used in handheld portable terminals like POS machines. These products feature high contrast and wide viewing angles, available in various display modes such as gray background with blue-black characters, yellow-green background with blue-black characters, and blue background with white characters. Utilizing COG (Chip-on-Glass) manufacturing technology, the products are slim, lightweight, and feature low power consumption. The module includes a driver chip and connects to the main MCU via an SPI or I2C interface, offering simple operation, excellent display quality, and stable performance.
STN and FSTN monochrome COG dot matrix LCDs feature a simple structure and mature, stable driver ICs, offering high reliability and long lifespan. They are suitable for high-frequency, long-duration operations like scanning and checkout in POS machines.
Monochrome screens themselves do not emit light or only require simple LED side lighting, resulting in low power consumption. This enables longer battery life for mobile POS machines and handheld terminals reliant on battery power. In environments with complex ambient light, such as supermarkets and outdoor markets, monochrome LCD modules offer good readability under strong light.
Monochrome LCD modules are low-cost and fully capable of displaying text (e.g., product name, price, quantity, total amount) and simple graphics. Choosing monochrome screens can significantly reduce overall machine costs and enhance product market competitiveness.
Monochrome LCD modules are applied in various POS equipment:
Desktop POS Machines: Used as the main display or a customer-facing secondary screen, stably displaying transaction details and amounts.
Mobile Handheld POS Terminals: Used for ordering and checkout in restaurants or for inventory counting in warehouses, where their low power consumption is an indispensable advantage.
Dedicated Transaction Terminals: Such as bank card readers and bus ticket vending machines, where display requirements are simple and fixed. Monochrome screens are the most economical and practical choice.
Portable Thermal Receipt Printers: Many incorporate small monochrome screens for displaying status and simple information.

VA LCD products are widely used in industrial alarm instruments such as multi-channel alarm meters, single-channel digital display alarm meters, status/process indicators, and dedicated gas detection alarm meters. The LCD screens digitally display real-time measurement values (temperature, pressure, etc.), alarm setpoints, analog displays (percentage), channel numbers, alarm status indications, gas concentration values (e.g., %LEL), and provide precise display of single-point parameters and threshold alarms. This enables the informational representation of instrument functions for monitoring production process parameters and ensuring personal and property safety.
