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.

—— Darkwynd

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

Reliable, Cost-Effective Touch Display Solution for Demanding Embedded Applications

 

Saef Technology Limited presents the SF-TC350H-8812A-T, a robust 3.5-inch TFT LCD module engineered for applications where durability, simplicity, and reliability are paramount. Featuring a 320×480 resolution, integrated resistive touch panel, and a widely supported 16-bit parallel interface driven by the ILI9488 IC, this module is ideal for industrial HMIs, medical devices, point-of-sale systems, and embedded control panels.

 

Engineered for Stability & Ease of Integration:

  • Proven Resistive Touch Technology: With over 1,000,000 input cycles and linearity within ±1.5%, this RTP delivers reliable performance in environments where capacitive touch may be less suitable, such as gloved operation or dusty conditions.

  • Wide Operating Temperature Range: Certified for -20°C to +70°C operation and -30°C to +80°C storage, ensuring consistent performance in challenging environments.

  • Simple Interface & Low System Overhead: The 16-bit parallel interface reduces development complexity and is compatible with a wide range of microcontrollers and embedded processors, speeding up time-to-market.

  • Optical Performance Tailored for Readability: 300 cd/m² brightness and 250:1 contrast ratio provide clear visibility in typical indoor and industrial lighting conditions. The 12 o’clock viewing direction optimizes display orientation for vertical-mounted applications.

 

Technical Specifications for Design Consideration:

  • Power Supply: VDD = 2.8V ±0.2V, IOVCC = 1.8V–2.8V

  • Backlight: White LED edge-lit, 19.2V typical forward voltage (20mA drive)

  • Touch Panel Ratings: X-axis resistance 300–900Ω, Y-axis 200–500Ω; operating voltage ≤7V DC

  • Mechanical Outline: 54.48mm × 84.71mm × 3.25mm (max)

  • Compliance: Designed to meet industrial reliability standards with testing for high/low temperature, humidity, thermal shock, and vibration resistance
