Key Factors Before Integration

1. Display Size and Resolution

Choose the correct size (e.g., 3.5″, 5″, 7″) and pixel resolution (e.g., 480×320, 800×480) based on your device’s requirements.

2. Interface Type

Common options: RGB, MCU, SPI, MIPI DSI, LVDS. Interface selection affects data transmission speed and complexity.

3. Power and Backlight Considerations

Ensure voltage and current meet module requirements. Consider LED driver compatibility.

4. Operating Environment

Is the device exposed to sunlight, vibration, or extreme temperatures? Choose sunlight-readable or wide-temperature TFT modules.

Step-by-Step Integration Guide

Step 1: Select the Right Module
Check parameters: size, resolution, interface, viewing angle, brightness.

Step 2: Mechanical Design Integration
Use the module’s 2D/3D CAD files to align with your enclosure design.

Step 3: Interface Connection and Driving
Choose the matching interface (SPI, RGB, etc.) and select a compatible driver IC or development board.

Step 4: Display Control Software
Develop or adapt GUI software for data display, such as using STMicroelectronics TouchGFX or LVGL.

Step 5: Prototype and Testing
Test for brightness, viewing angle, response time, and compatibility with other system components.
