Customer Reviews
Very fast response to email and after payment validated item got shipped with express air freight and received within few days. Items were brand new in condition and even had pin header soldered which is a big plus. Very happy overall and will buy again!

—— Andreas Anderssons

As always 100 % best service....

—— Evto-WEb Aps. Denmark

The display is bright! Worked as expected using the libraries from Adafruit mention in other reviews. Also must use the SPI_MODE3 setting in the Init. I used the Arduino Nano, VCC to 5V and BKL to 3.3V. (PN: SFTM130JY-7181AN)

—— Richard Ingram

It is a straight up HDMI monitor with Micro-USB for power and touch controls. It's one fancy trick is that it is a 5 point (capacitive) touch monitor so it works just like a phone or a laptop screen with taps, drags, pinches and other touch gestures. When in extended mode both switched to their native resolutions and the display was nice and sharp.

Hello Janco, Hope you are well. We were very happy with the quality of the previous batch of 2.42 inch OLED displays that we brought from you (see below). We would like to place another order for XXXX pcs.

—— Libby

I have this set up as a monitor for a security system. It works great after I did some troubleshooting.

—— Michael Helms

Excellent work! Thank you I will keep your company in contact for next orders。

—— DEMAC S.A.

Overall a great monitor. I’m a road warrior and was looking a portable monitor that I could take with me to make my work more efficient. Overall impressed with the product. Screen looks good, is responsive, and colors/sharpness are good.

—— J Rau

Awesome little monitor for my projects.

—— Daniel Champagne

I got the samples within a week. Very fast delivery. This is a very nice display. Very sharp with good contrast. The viewing angles are a little better than some of the other displays I have used.

—— GeorgeB

Displays came well packaged with foam to protect the header pins against being bent in shipment. Came right up at the default 0x3C I2C address used by MicroPython's SSD1306 driver. Pre-soldered header is a time saver. Enough room for four lines by sixteen characters of tiny text. These are my new favorite displays. (0.91 OLED)

—— Detta

Easy enough to get set up, and good colors. Pure black is perfect, as expected from an OLED. Only issue I have is per-pixel writing - it takes about 1.5 seconds for a full refresh with my setup.

—— Ryan James

Great screens - were packed well and worked great!

—— Fletcher

This is not the first time we have ordered. At first, we ordered a trial batch of 10 pcs, then two times of 1000 pcs, and now 3000 pcs.

—— Josh

Hi Christina, The product we ordered, OLED 3.12inch display, have now been tested and all worked perfectly, 100%. Very happy with product, fast shipping and excellent customer service. We will place order for more displays in November. (SFOM312YZ7-25664WBYG-01) Best regards Andreas

—— Andreas Anderssons

I am working on the Reflections open-source mobile entertainment system and needed a bright display for a wrist-watch application. SAEF gave me great communication, answered my questions quickly, and sent me the parts quickly. -Frank

Beyond the Rectangle: Mastering UI Design and Integration for Circular TFT Displays
Latest company news about Beyond the Rectangle: Mastering UI Design and Integration for Circular TFT Displays

Introduction: The Allure and Challenge of the Circle
The shift from rectangular to circular displays marks a significant evolution in product design, driven by wearables, smart home interfaces, and premium industrial instruments. A circle is intuitive, space-efficient, and aesthetically distinctive. However, for engineers and designers in Munich, Stuttgart, Silicon Valley, or Boston, this shape introduces unique challenges: how do you design a compelling user interface (UI) for a non-rectangular canvas, and how do you integrate it mechanically into a compact product?

This article explores these challenges through the lens of a specific component: the 2.1-inch Round TFT LCD Module, model SFTO210XC-7000AN from Saef Technology Limited. With a sharp 480x480 circular resolution and an "all" viewing direction, it's a premium canvas for innovative design.

Part 1: Reimagining the User Interface for a Circular Canvas
Traditional GUI frameworks are built for rectangles. A 480x480 round display requires a rethinking of layout, information hierarchy, and animation.

  • Challenge: Wasted Space vs. Creative Layout. The active area is a 53.28mm diameter circle within a rectangular pixel array.

  • Solution & Datasheet Insight: The key is to embrace the shape. Design UIs that are radially symmetric. Use circular menus, ring-shaped progress indicators, and rotating data visualizations. The high 300 cd/m² luminance and 80-degree viewing angles (Page 10) ensure this radial UI remains clear and vibrant from any perspective. The 262K color depth enables smooth gradients and visual depth, crucial for creating immersive watch faces or gauge clusters.

Part 2: Mechanical and Electrical Integration in Tight Spaces
A 2.1-inch round display is often chosen for its compactness, but integrating the driver board and connectors demands careful planning.

  • Challenge: PCB Real Estate and Connector Placement. The module's 58.18mm x 60.71mm outline includes a significant PCB "chin" housing the 40-pin connector (Page 4, 5). This must be accounted for in the product's internal layout.

  • Solution & Datasheet Insight: Successful integration requires early collaboration between mechanical and electrical engineers. The pin assignment (Page 5) reveals a hybrid 3SPI+18RGB interface. The SPI pins (CS, SCK, SDA) can be used for initial configuration of the ST7701S driver IC, while the RGB interface streams display data. This flexibility allows designers to optimize their host processor's resource usage. Furthermore, dedicated pins for touch (TP_INT, TP_SDA, etc.) are pre-laid out, signaling readiness for a complete touch solution.

Part 3: From Display to Interactive Experience: Adding Touch
A beautiful circular interface begs to be touched. Transforming this display into a touch-enabled HMI is a critical upgrade.

  • Solution: Saef Technology Limited expertly laminates high-quality Capacitive Touch Panels (CTP) onto this circular display. This creates a seamless, flush surface that is intuitive for end-users. The touch controller communicates via the dedicated I2C pins (TP_SDA, TP_SCL), keeping the interface clean. For applications requiring gloves or a stylus, a Resistive Touch Panel (RTP) option is also available. This turnkey "display + touch" solution drastically reduces development time and complexity.

Conclusion: The Circle as a Competitive Advantage
Implementing a circular display is more than a component swap; it's a strategic design decision that can define a product's identity. The SFTO210XC-7000AN provides the high-performance foundation—with its square-pixel circle, wide viewing angle, and robust interface. By mastering circular UI principles and leveraging expert integration support, engineers can create products that are not only functional but also distinctive and desirable.
