Product Description
3.4inch TFT LCD DISPLAY MODULE with 480(RGB)x480 Resolution and 350 cd/m² Brightness for Harsh Environments
The 3.4 Inch TFT LCD Display Module is a fully integrated display unit that combines a high-performance 3.4-inch TFT LCD panel, built-in driver IC (optimized for ST7789V3), LED backlight, FPC (Flexible Printed Circuit), and metal frame—providing a ready-to-use solution for manufacturers seeking hassle-free integration. Unlike standalone TFT screens, this module is a complete display subsystem, designed to simplify the production process, reduce R&D costs, and shorten time-to-market—key priorities for Western businesses. The 3.4-inch size’s unique advantage shines here: it delivers enhanced visibility (compared to 3.2-inch modules) while remaining compact enough to fit into portable, industrial, and medical devices. Equipped with a high-resolution 480×800 IPS panel.
Note1: The LED driving condition is defined for each module.
Note2: When LCM is operated, the stable forward current should be inputted. And forward voltage is for reference only.
Note3: Optical performance should be evaluated at Ta=25℃ When LED is driven at high current, high ambient temperature & humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical operating life time is estimated data.
Note4: The LED driving condition is defined for each LED module.

Product Advantages
-
Fully Integrated Design: Combines TFT panel, driver IC (ST7789V3), backlight, FPC, and metal frame into one complete unit, eliminating the need for separate assembly of components—reducing R&D and production costs, and shortening time-to-market for manufacturers.
-
Optimal Size Benefit: 3.4-inch diagonal offers enhanced display area for detailed data and improved readability, while remaining compact enough for portable and space-constrained devices—filling the gap between smaller 3.2-inch and larger 3.5-inch modules.
-
Flexible Compatibility: Supports RGB and SPI interfaces, compatible with popular microcontrollers (Arduino, Raspberry Pi, ESP32-C3), and offers customization options (touch screen, brightness adjustment, wide temperature range) to meet diverse application needs.
-
Superior Display Performance: 450 cd/m² high brightness, 1000:1 high contrast, and 11ms fast response time deliver sharp, smooth visuals—suitable for real-time data display and dynamic content playback, critical for industrial and medical applications.
-
Easy Installation & Maintenance: Compact size, standardized interface, and robust structure make installation quick and easy, while the integrated design reduces the risk of component failure—lowering maintenance costs for businesses.
-
Maker-Friendly: Compatible with popular DIY platforms (Arduino, Raspberry Pi), catering to Western maker communities and expanding market reach.
-
Reliable & Compliant: Industrial-grade stability (optional wide temperature range), EMC Class B compliance, and RoHS/REACH certification ensure compatibility with global markets and harsh operating conditions.
Application Fields
The 3.4 Inch TFT LCD Display Module, as a fully integrated display unit, is widely used in scenarios that require easy integration, high stability, and enhanced visibility—leveraging the 3.4-inch size’s unique balance of display area and compactness. Key applications include:-
Industrial Control: HMI (Human-Machine Interface) for small industrial equipment, PLC control panels, equipment status monitors, and industrial automation terminals (where easy integration and clear data display are critical).
-
Medical Equipment: Portable medical monitors, blood glucose meters, small diagnostic devices (requiring high stability and clear display of detailed health data), and medical handheld scanners.
-
Automotive Electronics: In-car displays, dashboard auxiliary screens, car diagnostic tools, and motorcycle dashboards (where the 3.4-inch size fits seamlessly and enhances visibility of critical information).
-
Smart Home: Smart security panels, doorbells with display, home automation control terminals, and smart thermostat control panels (where enhanced readability improves user experience).
-
Industrial Instruments: Portable test equipment, environmental monitors, pressure gauges with digital displays, and handheld industrial detectors (where easy integration and durability are key).
-
DIY & Maker Projects: Compatible with Arduino, Raspberry Pi, and ESP32-C3, making it ideal for Western maker communities and DIY electronic projects (e.g., custom handheld devices, smart prototypes).
