UART Display

UART Display

A UART display (Universal Asynchronous Receiver Transmitter) is a widely adopted serial communication protocol that enables low-cost, low-power, and real-time data transmission between a host system and a display module. As an intelligent display solution, the UART display module integrates a TFT display controller, touch interface, and graphical resources, allowing developers to control screen content and interactive functions using simple command instructions—without the need for complex drivers or advanced programming languages. This greatly reduces both the development threshold and time-to-market.

The module includes a comprehensive built-in library of commonly used graphics, fonts, and animations, and supports JPEG, PNG (including transparency), image rotation and scaling, quick UI component layout, page transition effects, and multi-language font libraries, enabling a professional and visually rich user interface.

Designed with a modular architecture, UART display modules combine display control logic and touch functionality, and can be paired with a variety of TFT LCD panels. They connect directly to the host system (such as MCUs, ARM-based cores, or single-board computers) via the UART interface, eliminating the need for complex wiring or driver development. With just a few simple commands, developers can control display content and receive user feedback, significantly accelerating project development timelines.
