3.9 Inch TFT LCD Module (480×800) IPS
The DBT039BVC31M035A is a 3.97-inch Color TFT-LCD Module designed for modern HMI applications. Featuring a vertical 480×800 resolution and IPS Full View technology, it delivers vibrant, sharp images from any angle.
Engineered with In-Cell Touch technology, this module integrates the touch sensor into the LCD cell, resulting in an ultra-slim 3.36mm profile. With a high-speed MIPI interface and robust 6H surface hardness, it is the ideal solution for smart home thermostats, handheld POS, and medical instruments.
Compact Brilliance: 3.97″ In-Cell Touch Display
In the world of IoT and smart devices, the user interface is everything. The 3.9 Inch TFT LCD Module (Model: DBT039BVC31M035A) brings the responsiveness and clarity of a smartphone screen to your industrial and smart home projects.
In-Cell Technology: Thinner & Clearer
Unlike traditional screens that bond a touch panel on top of the LCD, this module uses In-Cell Technology. The touch sensors are embedded within the liquid crystal layer.
-
Ultra-Slim Profile: At just 3.36mm thick, it fits perfectly into slim wall panels or sleek handheld housings.
-
Better Optics: Eliminating the air gap or extra adhesive layer reduces reflection and improves light transmittance, making the 16.7M colors pop.
IPS Full Viewing Angle
Designed for versatility, the IPS panel ensures that the screen is readable from 80/80/80/80 degrees. Whether mounted vertically on a wall thermostat or held in a hand, the colors remain accurate without washing out.
High-Performance MIPI Interface
Driving a 480×800 resolution requires significant data throughput. This module utilizes the MIPI interface, commonly found on high-performance processors (like STM32H7, Raspberry Pi CM4, or Rockchip). This ensures smooth 60fps animations and responsive touch feedback, far superior to older SPI or MCU interfaces.
Built for Usage
-
Durability: The cover glass features 6H hardness, protecting against scratches from daily use.
-
Environment: With an operating range of -20°C to +60°C, it is suitable for both indoor control panels and semi-outdoor handheld usage.

📥 Request Datasheet & Driver Code
Technical support available for MIPI initialization.
Q: What is the benefit of the MIPI interface for a 3.9-inch screen? A: A resolution of 480x800 contains 384,000 pixels. Traditional SPI or 8080 interfaces struggle to refresh this many pixels at 60Hz without screen tearing. MIPI DSI (Display Serial Interface) offers high-speed differential signaling, allowing for fluid animations and complex UIs, making it perfect for modern smart home interfaces.
Q: Can this screen be used in Landscape mode? A: The native resolution is 480x800 (Portrait). However, you can rotate the display content 90 degrees in your software/driver to use it as an 800x480 (Landscape) display. Please note that the polarization is optimized for full viewing angles (IPS), so it will look good in either orientation.
Q: Does it support custom Cover Glass (e.g., with a logo)? A: Since this is an In-Cell module, the touch sensor is integrated inside the LCD cell. Customizing the cover lens (adding a logo or changing the shape) is possible but typically requires a higher MOQ compared to discrete CTP solutions. Please contact our sales team for customization options.
Q: What is the pin definition for the MIPI connector? A: The module typically uses a standard FPC connector. For the full pinout diagram and the initialization code for your driver IC, please request the full datasheet below.
Q: What is the MOQ?
A: The MOQ for our products is 1 piece. We are able to provide support throughout the testing process.
Q: What about the delivery time?
A: We have products in stock and can ship them within 3 working days.
Q: Does your product have any warranty?
A: Yes, we offer a warranty that ensures the LCD will function properly upon receipt. However, please note that we do not provide guarantees for any damage caused during use.
Q: What’s your payment method?
A: We accept several payment methods, including T/T (bank transfer), and PayPal.
