Understanding UART TFT Displays: Benefits, Applications, and Features
Why UART TFT displays could be the ideal choice for you
UART TFT displays are versatile and efficient solutions for creating dynamic graphical user interfaces (GUIs) in various applications. Leveraging the Universal Asynchronous Receiver/Transmitter (UART) communication protocol, these displays offer seamless connectivity with a wide range of microprocessors, from basic models to advanced systems. This ease of integration, combined with vibrant color output and advanced features, makes UART TFT displays an ideal choice for developers looking to enhance their human-machine interfaces (HMIs) without overwhelming their microprocessor resources. In this blog, we will explore the key benefits, applications, and unique features of UART TFT displays, highlighting why they are a valuable addition to any project.
What are UART TFT Displays?
UART TFT Displays are colour TFT LCD that can communicate with a microprocessor via a UART port (TX, RX).
Why a UART port (TX, RX)?
UART (Universal Asynchronous Receiver/Transmitter) is a device-device communication protocol that is supported by most of today’s microprocessors. Even the simplest of microprocessors may include one or more UART ports that allows connection to a UART display.
Why a UART TFT Display?
For many existing applications, it is unnecessary to upgrade your microprocessor as most will have at least one UART port. A UART TFT display when connected via UART uses no major microprocessor resources.
Why Crystal Display Systems?
Crystal Display Systems and their partner DWIN Technology, a developer and manufacturer of Smart UART TFT display modules commit to building long term customer partnerships here in the UK and throughout the world by offering free development samples and direct technical support for both hardware and software by a dedicated team of engineers. With DWIN’s extensive choice of smart displays, powerful development tools plus local and factory support we believe we can reduce your development times and enable you to build a very cost-effective HMI solution with the right display and a powerful graphical user interface.

Why our UART Displays?
Our COB UART display range starts at a 1.3” 240×240 resolution size and goes up to a 21.5” 1920×1080 full HD resolution and encompasses all the key display sizes in-between, also included are versatile bar types (letterbox format) and modern contemporary circular options as well as a range of super slimline COF versions. IPS wide view technology is used extensively across the range, delivering wide viewing angles and consistent image quality across all viewing directions
At the heart of the complete UART Display range is a dual-core processor based on the ever popular and stable intel 8051 architecture, plus DWIN’s own powerful development software, DGUS. The DGUS design tool allows system designers to build their graphical user interface including touch functionality by simply importing images, fonts and music files from popular software programmes, vastly reducing the GUI development time. Once complete your GUI can be quickly and simply transferred to the UART Display’s 16MB FLASH (expandable to 64MB) memory via SD card or RS232/USB adaptor boards.
Communication to your application’s microprocessor is via the displays integrated UART interfaces, with a choice of TTL or RS232 with some models also having a dedicated RS485 or CAN-Bus.
The standard operating temperature range is -20°C to +70°C, however the demand for displays that can withstand harsh environmental conditions has become increasingly vital across various industries. To address these needs DWIN have developed a range that emerge as a beacon of innovation, designed to thrive in severe environments where standard displays falter. Ranging from 3.5” to 15.0”, these displays boast standard sizes and formats, incorporating a blend of IPS wide view and TN TFT technology at competitive prices. Without doubt, the operational prowess of these displays spans an impressive -40C to +85C temperature range, ensuring resilience in extreme climates. Moreover, the incorporation of UV protection, ESD, EFT, Radio Interference, surge protection and a conformal coating on critical components to protect against moisture contamination, render them indispensable in hostile settings. Additionally, with full touch functionality provided by both 4-Wire resistive and Projected Capacitive technologies and a custom cover lens service make these displays a cutting-edge solution for diverse applications within medical, industrial automation, auto/aero/rail, and industrial process control markets.
DWIN’s Smart UART Displays stand as a testament to technological ingenuity, providing a robust solution for demanding environments. Furthermore, as we navigate an era where technology meets adversity, DWIN’s Smart UART Displays prove to be indispensable, offering not just resilience, but a forward-thinking approach to HMI display solutions in the face of challenging environments. In conclusion, whether it’s outdoor applications or critical industrial processes, these displays redefine what’s possible, ensuring seamless performance in the harshest conditions.
