Brightness directly affects readability in various environments.

4.2 Ensure Interface Compatibility

Common interfaces for 7-inch TFT LCD Displays include:

RGB

LVDS

MIPI

MCU

SPI (for some smaller modules)

Each interface corresponds to different signal types and refresh methods. Compatibility with the mainboard or controller must be confirmed in advance.

4.3 Choose the Right Touch Technology

Depending on the application, you may need:
