7” 800x480 TFT DSI Capacitive Touchscreen for Raspberry Pi (V1.0)

Jargon buster

Plain-language definitions for the technical terms used above.

DSI

DSI stands for Display Serial Interface, a high-speed connection commonly used to send video data from a computer board to a display. It matters because DSI signals are not simple GPIO wires, so the cable, connector, and signal routing need to match the display interface.

FPC

FPC stands for flexible printed circuit, a thin flat flexible cable or connector style often used where space is tight or some movement is needed, commonly for displays, cameras and other high-density connections. Connecting to an FPC connector generally needs a matching cable with the correct pin count, pitch and contact orientation.

HMI

HMI stands for Human-Machine Interface, meaning the screen, buttons or controls a person uses to interact with a device. Describing something as suited to HMI use suggests it is intended for user-facing applications such as control panels, dashboards or instrument displays.

M2.5

A metric screw thread size with a 2.5 mm nominal diameter. It matters for mounting because screws, standoffs, and holes must use the same size to fit securely without damaging the board.

Multi-touch

Multi-touch means the touchscreen can detect more than one finger contact at the same time. This matters for interfaces that use gestures such as pinch-to-zoom, two-finger scrolling, or on-screen controls used together.

potentiometer

A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.

TFT

A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
