Starting From 5 Key Parameters, Accurately Select The Character Display Module
How to quickly make the right decision when selecting a character display module for industrial control, medical equipment, or smart home appliances, facing numerous specification parameters? Shenzhen Xinnuoya Display Technology Co., Ltd. has summarized 5 core selection dimensions for you based on years of experience in source factories.
1. Display format and character size
The common formats for standard character modules are 16×2, 20×2, 20×4, etc., which represent the number of characters and lines per line. Choose the appropriate character size (such as 2.0mm~5.0mm character height) based on your product panel space and reading distance. Xinnuoya supports standard and non-standard format customization.
2. Interface type
The mainstream interfaces include parallel (6800/8080), SPI, and I ² C. If your main control MCU has limited pins, it is recommended to choose SPI/I ² C interface; If fast refresh is needed, parallel interfaces are better. We can provide multiple interface adaptation solutions.
3. Backlight color and brightness
Common backlight colors: yellow green, blue, white, amber. Yellow green provides visual comfort in low light environments, while white is suitable for high contrast requirements. Xinnuoya supports customers to specify backlight color and brightness values (cd/m ²), and provides LED side backlight or array backlight options.
4. Working temperature range
Consumer grade: 0 ℃~50 ℃
Industrial grade: -20 ℃~70 ℃
Automotive/Medical grade: -30 ℃~80 ℃
Please choose based on the final usage environment of the product. All modules in the Xinnuoya series are available in a wide temperature version to ensure stable display under harsh conditions.
5. Supply voltage and power consumption
Most character modules support 5V or 3.3V logic power supply. It is recommended to choose 3.3V for battery powered equipment and pay attention to backlight power consumption. We can optimize the backlight driver circuit to help customers reduce overall power consumption.
