MIPI Interface 3.97 Inch TFT LCD Display 480x800 24PIN For Fingerprint Lock
This 3.97-inch TFT LCD display offers a slightly larger screen area compared to standard 3.5-inch displays, providing enhanced visibility for embedded and DIY projects. It maintains the core benefits of TFT technology—vibrant colors, sharp resolution, and fast refresh rates—in a compact form factor ideal for applications requiring additional screen space while maintaining a small footprint.
The display features a 24-pin interface designed with FPC (Flexible Printed Circuit) connectivity and utilizes MIPI DSI interface (typically 2 channels). This mobile-optimized interface delivers higher transmission rates and lower power consumption compared to traditional interfaces. The 24-pin configuration includes power ground, differential data pairs, differential clock pairs, reset pins, and dedicated pins for LED backlight power and reset control, ensuring stable data transmission and reliable screen operation.
With a 3.97-inch diagonal size, this TFT LCD employs active matrix Thin Film Transistor technology combined with an IPS panel, providing wide 80-degree viewing angles from all directions. The 480x800 resolution with 0.108mm×0.108mm dot pitch delivers clear, detailed imagery suitable for vertical display applications. The display offers a 900:1 contrast ratio and brightness up to 600 nits for excellent visibility even in bright lighting conditions.
Powered by the ST7701S driver IC, this module operates within a narrow voltage range of 2.8-3.3V with low power consumption. It functions reliably in temperatures from -20℃ to 70℃ and can be stored in conditions ranging from -30℃ to 80℃, making it suitable for most daily and industrial environments. The compact module thickness of approximately 2mm (57.14×96.85×2.15mm dimensions) facilitates easy integration into space-constrained devices.
