Graphic LCD Displays

Graphic LCD displays provide a pixel-based output, allowing for custom graphics, symbols, charts, and text. Unlike character LCDs, which display fixed characters, graphic LCDs offer flexible layout design with various resolutions and pixel densities.

These displays are perfect for dynamic interfaces and are widely used in:

• Industrial machines

• Medical instruments

• Portable test equipment

• DIY electronics

• Home automation systems

Common display resolutions:

• 128x64 (most popular)

• 192x64, 240x128, 320x240, and more

• Monochrome or STN/FSTN displays

• Backlit options for low-light use

Most graphic LCDs use controller chips like KS0108, ST7920, or RA8835, and support parallel, SPI, or serial interfaces. They are compatible with Arduino, STM32, AVR, and ESP32 platforms with libraries like U8g2, GLCD, or Adafruit GFX.
