A 128×64 pixel graphic LCD module driven by the ST7920 controller. This display supports English characters, Chinese characters, and custom graphics over both serial (SPI) and parallel interfaces, making it a versatile choice for Arduino projects that need more than a simple character display.
The blue backlit screen provides good readability, and the ST7920's built-in character ROM means you can display text without loading custom fonts. For graphics and custom layouts, DFRobot provides Arduino libraries for both serial and parallel modes.

Jargon buster
Plain-language definitions for the technical terms used above.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- parallel interface
- A parallel interface sends several bits of data at the same time using multiple wires. It can be faster than simple serial connections, but it uses more microcontroller pins, so it is less convenient for small projects with limited wiring space.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
