STN LCD are widely used in detection instruments, display instruments, and regulation (control) instruments. They can meet the industrial instruments’ requirements for high precision, high reliability, and intelligence. At the same time, STN dot matrix displays can accommodate the needs of complex display content, such as showing adjustment parameters, setting alarms, and outputting control signals. STN segment displays are capable of multiplex drive and offer a wide viewing angle range. Paired with a 10mm-thick glass cover, they can be adapted for explosion-proof, dust-proof, and contamination-resistant environments, with an optional integrated touch function.

The 1.3?inch OLED display features an ultra?thin profile, high contrast ratio, and wide viewing angles. It adopts self?emissive technology, requiring no backlight, which results in extremely low power consumption, and supports a wide temperature operation range from -40?℃ to 70?℃. The module is equipped with standard SPI/I2C interfaces, making it compatible with mainstream microcontrollers. It is widely used in applications such as smart wearable devices, industrial instrumentation, portable medical equipment, and smart home control panels.

The COG LCD product is widely used in differential pressure flowmeters, positive displacement flowmeters, variable area flowmeters (rotameters), turbine flowmeters, electromagnetic flowmeters, vortex flowmeters, ultrasonic flowmeters, mass flowmeters, volumetric flowmeters, and more. Its dot matrix display can present information such as instantaneous flow rate, total accumulated flow, operational status indicators, engineering units, conductivity/empty pipe alarms, frequency/signal strength, temperature and density, speed of sound, and time of flight difference,?in multiple languages as well as digitally. It ensures the accurate and reliable display of measurement data from the instrumentation.

The 0.96 inch OLED is a compact, high-contrast display. It employs self-emissive technology, eliminating the need for a backlight. This results in an ultra-thin module structure that saves valuable internal space in devices. It is widely used in wearable devices, portable electronics, smart home appliances, and similar applications.

FSTN LCD enhances viewing angle width and improves background color uniformity (compared to STN LCD) through the compensation film process. FSTN is suitable for multiplex dynamic driving and can support up to 320-multiplex dot matrix products, making it ideal for complex graphic displays.

The Negative LCD series is widely used in elevator applications such as floor indicator panels, hall call display panels, car operation panels, LCD information panels, horizontal display panels, and monochrome LCD modules. Among these, the three most representative display modes are white characters on a blue background, white characters on a black background, and colored characters on a black background. The LCD segment display is employed to show the current floor number, indicate the direction of elevator movement, confirm selected floors, display overload warnings, provide arrival notifications, and respond to passenger calls by indicating operational statuses such as “Up,” “Down,” or “Stopping.” Additionally, touch-sensitive functionality can be integrated to meet human-machine interaction needs during elevator operation.

This product is an LCD 16×2 character dot matrix display module designed for ASCII character display, featuring 2 rows with 16 characters per row. The display utilizes an FSTN mode LED backlit LCD, showing blue-black characters on a gray background with high contrast and a wide viewing angle. The module includes a built-in character driver chip and is manufactured using COG technology, making it thin, lightweight, and energy-efficient. It connects to the main MCU via an SPI interface or an 8-bit parallel LCD interface.

VA LCD segment displays feature a black background with white characters, offering high contrast, a wide operating temperature range, broad viewing angles, and fast response times. They can be combined with color silk printing or color filter films to achieve TFT-like colorful display effects and can also be used in conjunction with TFT screens.

0.54-inch OLED display module is an ultra-compact, high-contrast solution designed for embedded systems and portable electronic devices. With a resolution of 96 x 32 pixels and an operating temperature range of -40 to 70°C, it enables clear information display within a minimal footprint. It is widely used in smart wearable devices, portable industrial instruments and meters, and controllers for small household appliances.

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.
