1.47 Inch TFT Color Display 172×320 ST7789 SPI

Product Description

The 1.47 Inch TFT Color Display is a compact full-color LCD module designed for embedded systems, microcontroller projects, portable electronics, and graphical user interfaces. With a 172 × 320 pixel resolution, the display provides a relatively high pixel density in a small form factor, making it suitable for applications where screen space is limited but detailed graphics, icons, measurements, and text are required.

The display uses an ST7789-family controller and communicates with the host microcontroller through a 4-wire SPI interface. SPI requires only a small number of communication lines compared with parallel display interfaces, making the module practical for microcontrollers with limited GPIO resources. It can be integrated with platforms such as Arduino, STM32, ESP32, Raspberry Pi, and other systems capable of driving an SPI display.

The 172 × 320 resolution provides 55,040 individual pixels, allowing the module to display detailed menus, graphical indicators, sensor readings, icons, charts, and other UI elements. Matching modules are available with 262K RGB color capability, providing significantly more visual information than monochrome displays or basic character LCDs.

Many versions use an IPS panel, providing wide viewing angles and consistent color reproduction when viewed from different directions. This makes the display useful for handheld instruments, control panels, wearable electronics, and other embedded products where the viewing angle can change during operation.

The compact display format is well suited to portable and space-constrained designs. Depending on the specific module or breakout board, the physical dimensions and connector arrangement can vary. For example, the Waveshare implementation measures approximately 22 × 38.5 mm, while other bare-panel and breakout versions have different dimensions.

The module can be used to build graphical interfaces for measurement equipment, IoT devices, robotics controllers, smart-home products, portable instruments, and development prototypes. Libraries and example projects are available for several popular development platforms, simplifying integration into embedded applications.
