It features a 98.0×60.0×15.0 mm module size, 76.0×25.2 mm viewing area, 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, 16PIN interface, white LED backlight, FSTN Positive LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
20 X 4 Character LCD Display is designed for readable character output, stable circuit connection, and efficient use in standard electronic control layouts. The 16PIN interface provides a direct parallel connection route for engineers who prefer conventional LCD control in industrial boards, testing devices, and custom product panels. Its FSTN Positive display structure improves text sharpness on a light background, while the white LED backlight gives the screen a clean appearance for indoor viewing. The module also supports high contrast, wide-temperature operation, low power consumption, anti-interference performance, multiple color combinations, technical data support, source code assistance, customization, 1–3 day sample preparation, cost-effective production, and fast batch delivery planning.
Applications
20 X 4 Character LCD Display is suitable for products that need structured information output without using a graphic display. It can present setup menus, measurement records, status feedback, count values, fault messages, operation steps, maintenance reminders, and user instructions in a four-line text format. Common application fields include measuring instruments, industrial control panels, medical equipment, home appliances, communication terminals, information display systems, consumer electronics, access devices, Arduino projects, and DIY development boards. Its 20×4 character capacity, FSTN Positive readability, white backlight, and 16PIN hardware connection make it practical for long-term equipment interfaces requiring stable and organized data presentation.
