3.5 Inch TFT LCD Module 320x480 ST7796 40pin
3.5 Inch TFT LCD Module 320x480 Dots ST7796 40pin Serial Interface Touch Optional
Key Features of a 3.5-Inch TFT Display:
Color Depth:
These displays support 16.7 million colors (24-bit color), meaning they can produce vibrant and accurate images and graphics.
Touchscreen (Optional):
Many 3.5-inch TFT displays come with a resistive or capacitive touchscreen layer, enabling user interaction via touch. Resistive touch is pressure-sensitive and works with any object (including a finger, stylus, or gloves), whereas capacitive touch is more sensitive and supports multi-touch gestures but usually requires conductive input (finger).
Interface:
SPI (Serial Peripheral Interface): Most 3.5-inch TFT displays use SPI for communication with microcontrollers or single-board computers like Arduino and Raspberry Pi. SPI uses fewer pins than parallel communication, making it more compact and easier to connect.
Parallel Interface: Some larger TFT displays use parallel communication for faster data transfer, though they require more I/O pins.
