Product Overview

This 3.5-inch High Brightness TFT LCD Display Module is a versatile, high-quality screen solution designed for industrial, embedded, and multimedia applications. With a resolution of 640×480 pixels (VGA) and a 54-pin interface, it supports both RGB and SPI communication protocols, offering flexibility for different system requirements. The display delivers excellent visual performance, characterized by high brightness, vivid colors, and wide viewing angles, making it suitable for both indoor and outdoor environments.

Key Features

• High Brightness Backlight
  Equipped with a powerful LED backlight, the display ensures clear visibility even under strong ambient light conditions, making it ideal for outdoor devices, industrial controls, and portable equipment.

• Dual Interface: RGB + SPI

  • RGB Interface: Provides high-speed data transmission for full-color, high-refresh-rate display, suitable for dynamic graphics, video, or GUI applications.

  • SPI Interface: Offers a simpler, lower-pin-count alternative for basic display tasks or MCU-based systems with limited I/O resources.

• 54-Pin Connector
  The comprehensive pinout supports display data, touch control (if integrated), backlight control, and power supply, ensuring easy integration with common driver boards or custom circuits.

• Compact and Robust Design
  The 3.5-inch form factor balances size and readability, while the module is built with durable components suitable for long-term operation in demanding environments.
