LCDs for Medical Electronic Infusion Pumps An electronic infusion pump is a precision device widely used in the medical field. Its human-machine interface (HMI) typically utilizes Segment LCDs, Dot Matrix LCDs, or TFT LCDs. Among these, Segment LCDs are the most commonly used in infusion pumps. Segment LCDs offer advantages such as low cost, low power consumption, and high reliability, making them highly suitable for displaying critical parameters like flow rate and volume, which are often numerical values or fixed symbols.

The STN and FSTN single-color dot-matrix LCD screens, with resolutions of 128×128,128×64, and 192×64, can display graphics and multi-line text. Widely used in commercial retail terminals such as cash registers, these products feature high contrast ratio and wide viewing angles. They offer multiple color modes including gray background with blue-black text, yellow-green background with blue-black text, and white text on blue background. Utilizing COG manufacturing technology, they are lightweight, thin-profile, and energy-efficient. The modules contain built-in driver chips that connect to the main control MCU via SPI interface or 8-bit parallel LCD interface, ensuring simple operation, excellent display quality, and stable performance.

LCD Display for Air Purifiers: Essential home air purifiers typically display real-time PM2.5 readings, formaldehyde (HCHO) levels, allergen concentrations, temperature/humidity readings or alerts, wind speed, operating modes, and emergency notifications. Some models feature touch-sensitive LCD interfaces. These devices usually come with backlighting for clear visibility in dim environments and are often equipped with color screen printing and tinted film for enhanced visual clarity.

The segment COG module features a TN or VA LCD display with LED backlighting, ensuring clear visibility in both bright and dim environments. Utilizing the COG technology, it integrates driver chips and connects to the main MCU via SPI/I2C interfaces through flexible printed circuits (FPC) or metal pins. This lightweight design offers wide temperature tolerance, low power consumption, user-friendly operation, and excellent cost-effectiveness. Customizable configurations are available for various LCD types including TN, HTN, STN, FSTN, and VA. The display supports seven-segment numbers and customizable graphic symbols, making it widely applicable in automotive air conditioning controllers.

Vehicle-mounted LCD displays require exceptional electrostatic discharge (ESD) resistance. Given the complex and dynamic automotive environment, electrostatic discharge (ESD) remains a primary cause of electronic component failures. The anti-static standards for automotive displays are exceptionally stringent, far exceeding those of consumer electronics. Common contact discharge levels typically range from ±4kV, ±6kV, and ±8kV, while airborne discharge levels generally exceed ±8kV, ±15kV, and ±25kV Core requirements: clear, stable, reliable, low power consumption.

Monochrome LCD screens in biosafety cabinets and medical transport cabinets are designed to monitor equipment status, display operational parameters, and support user interaction while meeting the specific requirements of biosafety environments. VA segment displays feature high contrast, wide viewing angles, and a broad temperature range, featuring fixed color icons (e.g., fans, alarm symbols) and numerical parameters. 192×64 dot matrix screens with STN negative display mode offer high contrast and wide viewing angles, supporting simple graphics (e.g., airflow diagrams) and multi-line text. These monochrome LCD screens prioritize functionality, reliability, and cost control in biosafety cabinets, making them suitable for mid-to-low-end models or scenarios where color accuracy is not critical.

Fitness equipment such as treadmills, rowing machines, and spin bikes typically utilize LCD segment displays for their cost-effective interface. Core requirements include clarity, stability, reliability, and low power consumption. Essential display features encompass basic exercise metrics (time, speed, distance, calories burned, heart rate, preset programs, and difficulty levels), while ensuring operation in complex environments like gyms or homes with temperature variations, vibrations, and lighting changes.

LCD Applications in Agriculture: Agricultural equipment and monitoring instruments. Given the complex and ever-changing environments, corresponding LCD products must demonstrate high reliability. Specific requirements include: ultra-wide temperature tolerance, UV resistance, vibration resistance, high humidity tolerance, strong light visibility, low power consumption, and long lifespan. The products should also meet low-power operation standards and adapt to battery or solar power supply conditions.

The VA segment code COG LCD module, known for its high reliability, superior optical performance, and cost-effectiveness, has become an ideal choice for display systems in small electric vehicles. This custom segment code COG module features a VA LCD screen, which is manufactured using the COG process and integrated with a driver chip. The LCD screen operates in VA mode and is connected to the main MCU via an I2C interface, using FPC (Flexible Printed Circuit) technology. This type of LCD module can be customized according to specific needs, offering high contrast, wide viewing angles, excellent display quality, a broad operating temperature range, low power consumption, a lightweight design, and stable performance.
