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

Technical Deep Dive: Leveraging the 2.4-inch 480x640 TFT Display for Robust Industrial HMI
Latest company news about Technical Deep Dive: Leveraging the 2.4-inch 480x640 TFT Display for Robust Industrial HMI

Introduction: The Demand for Clarity and Reliability
In the realm of Industrial Human-Machine Interfaces (HMI), portable medical devices, and advanced point-of-sale systems, the display is a critical touchpoint between user and machine. It must deliver sharp visuals, unwavering reliability, and seamless integration. The SFTO240PY-7404AN from Saef Technology Limited is a 2.4-inch TFT LCD module engineered to meet these exacting standards. With its high 480x640 resolution, 24-bit RGB interface, and robust ST7701S drive IC, this module is a powerhouse for demanding applications. This article provides a technical deep dive, exploring how its specifications translate into real-world performance and design simplicity for engineers in Germany, the United States, and other industrialized nations.

Decoding the Core Specifications: A Foundation for Performance
At the heart of any display selection are the fundamental specs that dictate its capabilities. The SFTO240PY-7404AN is built on a solid foundation:

  • Screen Size & Resolution: The 2.4-inch diagonal screen boasts a sharp 480 (RGB) x 640 (V) pixel array. This VGA-esque density results in a fine pixel pitch of 76.5µm, rendering crisp text, detailed graphics, and smooth lines essential for data visualization and user interfaces.

  • Color & Interface: Utilizing a full RGB 24-bit interface, the module can display 262K colors. This ensures smooth color gradients and accurate image reproduction, which is crucial for diagnostic displays and status indicators. The parallel RGB interface is a widely supported standard, simplifying connection to most modern microprocessors and FPGAs.

  • Drive IC: The integrated ST7701S drive IC is a key enabler of performance. It not only manages the pixel matrix efficiently but also offers flexibility in interface timing (supporting both DE and Sync modes) and includes built-in functionality for gamma correction and power sequencing, reducing external component count.

Conquering Design Challenges: Optical and Electrical Integrity
Beyond the basic specs, several features directly address common design hurdles.

  • Challenge 1: Readability in Varied Lighting. With a typical luminance of 300 nits and a high contrast ratio of 1200:1, this display remains clearly visible under bright factory lighting or ambient office light. The "Normally Black" mode ensures a deep, true black state, enhancing contrast and readability.

  • Challenge 2: Consistent Viewing Angles. The module offers wide 80-degree viewing angles in all directions (Left, Right, Up, Down). This is vital for devices where multiple operators may view the screen from different positions, ensuring color and contrast remain consistent.

  • Challenge 3: Power and Signal Integrity. The module operates from a low 2.8V analog supply, with a typical power consumption of just 23mA. The pin assignment clearly separates power and ground lines, aiding in the design of a clean and stable power delivery network to minimize noise.

Enhancing Functionality: The Touchscreen Addition
While the core display module is highly capable, modern HMI often requires interactivity. Saef Technology Limited offers standard and custom capacitive or resistive touchscreen overlays that can be seamlessly integrated with the SFTO240PY-7404AN. This transforms the module into a complete touch-display solution, ready for intuitive user input without significant mechanical redesign.

Conclusion: A Display Engineered for Excellence
The SFTO240PY-7404AN is more than just a list of specifications; it's a carefully engineered solution for professional applications. Its combination of high resolution, accurate color, robust ST7701S driver, and industrial-grade reliability makes it an ideal choice for engineers who cannot compromise on quality.
