800x800 3.4 Inch TFT LCD Display Module 350 cd/m2 LCD TFT Display Panel

The 3.4 Inch Standard SMALL TFT DISPLAY is a high-performance standalone display panel, engineered to maximize the 3.4-inch size’s core advantage: enhanced visibility without compromising portability. Unlike integrated modules, this standalone panel focuses on pure display performance, making it the perfect choice for manufacturers seeking full customization control while upgrading from smaller 3.2-inch screens. Built with advanced TFT (Thin Film Transistor) technology and an IPS (In-Plane Switching) panel, it delivers exceptional image clarity, vibrant 16.7M colors, and a fast 12ms response time—ensuring smooth visuals for both static data and dynamic content. The 3.4-inch diagonal offers a critical upgrade over smaller sizes: its 800(RGB)x800 WVGA resolution (higher than the 800(RGB)x800 of 3.2-inch models) and expanded display area make it ideal for devices requiring detailed text, icons, or basic graphics—all while remaining compact enough to fit into portable gadgets, smart wearables, and small household appliances. Equipped with a 400 cd/m² high-brightness LED backlight

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.

• 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 Arduino, Raspberry Pi, and ESP32-C3, 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.

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).
