Description
The 12864 128×64 Graphic LCD Display Module is a versatile monochrome graphical display designed for Arduino, 3D printers, RAMPS boards, robotics, CNC machines, and other microcontroller-based projects. With a 128×64 pixel resolution, it can display text, numbers, symbols, icons, menus, and custom graphics.
The display features a blue background with white pixels, providing clear and easy-to-read visual output. Unlike standard character LCDs, this graphical display gives you pixel-level control, allowing you to create custom fonts, shapes, graphics, status screens, and simple animations.
The module supports parallel and serial/SPI communication, with the interface mode selected through the PSB pin. When used in serial mode, fewer connections are required, making it a convenient option for projects where microcontroller GPIO pins are limited.

Parallel and Serial Communication
One of the major advantages of the 12864 graphic LCD module is its flexible communication options. The display can be configured for parallel or serial communication using the PSB interface-selection pin.
In serial/SPI mode, the number of required signal connections can be reduced, making it easier to integrate the display into compact Arduino and embedded projects.
Graphic Display Capability
The 12864 display provides much more flexibility than a conventional 16×2 or 20×4 character LCD. You can control individual pixels to create your own graphical interface.
Depending on your software and controller configuration, you can display:
- Custom text and fonts
- Numbers and symbols
- Icons
- Lines and boxes
- Circles and shapes
- Sensor readings
- Menus and status screens
- Progress indicators
- Graphs
- Simple animations
This makes the display particularly useful for projects that require more than basic character-based information.
