Key Specifications
I2C Display Module is a 20×2 character LCD designed for equipment that needs more text space than standard 16×2 displays. The JXD2002A-IIC model provides a 116.0×37.0×20.0 mm module size and an 83.0×18.6 mm viewing area, allowing two longer lines of letters, numbers, menu prompts, and parameter data. It supports 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, IIC/I2C interface, white LED backlight, and VA negative display mode. The module also supports -20°C to +70°C working temperature, -30°C to +80°C storage temperature, and a 06:00 viewing angle for stable panel readability.
Design Standards
I2C Display Module is developed for simplified wiring, high-contrast viewing, and efficient embedded product integration. The IIC/I2C interface reduces pin usage compared with traditional parallel connection designs, helping engineers save controller resources and shorten PCB routing work. Its VA negative screen creates a dark-background display effect with strong visual contrast, while the white LED backlight improves character recognition in modern control interfaces. The design also supports low power consumption, high anti-interference performance, multiple color combinations, technical documentation, source code support, customization, 1–3 day sample preparation, and batch delivery as fast as 15 days.
Applications
I2C Display Module is suitable for products that need longer two-line character content, such as setting menus, device status, measured values, fault codes, operation guidance, and system messages. It can be used in meters, equipment control panels, information display systems, home appliances, industrial controllers, medical devices, consumer electronics, and DIY development projects. Its 20×2 format, I2C communication, VA negative contrast, and larger viewing area make it practical for compact products that require clearer information layout without switching to a graphic LCD screen.
