The 128×64 Dot Matrix Graphic LCD Display is a monochrome graphical display module designed for embedded electronics, instrumentation, control panels, and microcontroller projects.
With a resolution of 128 × 64 pixels, the display provides significantly more flexibility than standard character LCDs, allowing developers to create custom text, symbols, icons, menus, status indicators, graphs, and simple graphical user interfaces.
The green LCD screen provides a clear and professional appearance, making the module suitable for both prototyping and finished electronic equipment.
Key Features
- 128 × 64 pixel graphic LCD
- Blue display screen
- Monochrome graphical display
- Supports text, symbols, icons, and custom graphics
- Suitable for menu-based interfaces
- Compact embedded display solution
- Low power consumption
- Suitable for microcontroller applications
- Ideal for control panels and instrumentation

- More flexible than standard character LCD modules
128 × 64 Graphic Resolution
The display provides a matrix of:
- 128 horizontal pixels
- 64 vertical pixels
- 8,192 individually addressable pixels
Unlike traditional 16×2 or 20×4 character LCDs, a graphical LCD allows the application to control individual pixels.
This makes it possible to display:
- Text
- Numbers
- Symbols
- Icons
- Logos
- Menus
- Progress bars
- Battery indicators
- Sensor readings
- Simple graphs
- Custom user interfaces
Green LCD Screen
The green screen provides a clean visual appearance suitable for electronic equipment and control interfaces.
Depending on the specific LCD version, characters and graphics are displayed with contrasting illuminated or non-illuminated pixels against the blue background.

Important Compatibility Note
Different 128×64 LCD modules can use different controllers, pinouts, interfaces, operating voltages, and backlight connections.
Before connecting the display, verify the exact model number or controller used by your module.
Common 128×64 graphic LCD modules may use controllers such as ST7920, KS0108-compatible controllers, or other LCD controllers, but these should not be assumed without checking the specific module.
Always verify:
- Supply voltage
- Controller type
- Pin configuration
- Communication interface
- Backlight voltage/current
- Logic voltage
before connecting the display to a microcontroller.
