LCD 1.44 Inch Colored Screen TFT SPI Module 128X128

The 1.44-inch SPI TFT LCD Display Module is a compact full-color display designed for embedded systems, Arduino projects, and other microcontroller applications. Featuring a 128 × 128 pixel resolution and the ST7735 display controller, it delivers vibrant 65K-color graphics while requiring only a few GPIO pins through its SPI interface. Its small size, fast refresh rate, and low power consumption make it ideal for portable devices, instrumentation, robotics, IoT projects, and graphical user interfaces.

Features

  • 1.44-inch full-color TFT LCD display.
  • 128 × 128 pixel resolution.
  • Driven by the ST7735 display controller.
  • SPI interface for high-speed communication.
  • Supports up to 65K RGB colors.
  • Low GPIO usage with SPI communication.
  • Integrated LED backlight.
  • Compact design suitable for embedded applications.
  • Compatible with Arduino, ESP32, STM32, Raspberry Pi, and other SPI-capable controllers.

Principle of Operation

The display communicates with a host microcontroller using the SPI (Serial Peripheral Interface) protocol. The microcontroller sends commands and pixel data to the onboard ST7735 controller, which stores the image in internal display memory and refreshes the TFT LCD accordingly.

The Data/Command (A0/DC) pin selects whether transmitted bytes represent display commands or pixel data, while the Chip Select (CS) pin enables communication with the display. The RESET pin initializes the controller during startup, and the LED pin powers the display backlight.
