7-inch eDP IPS Touch Display for LattePanda IOTA/3 Delta

Jargon buster

Plain-language definitions for the technical terms used above.

6H surface hardness

6H is a pencil-hardness rating used to describe how resistant the screen surface is to scratching. A higher hardness rating helps in portable or classroom projects where the display may be touched often or handled roughly.

DisplayPort

A digital display interface used to connect monitors and other video displays. It matters because the supported DisplayPort version affects display resolution, refresh rate and monitor compatibility.

eDP

Embedded DisplayPort (eDP) is an internal display interface used to connect a computer board directly to a built-in panel rather than an external monitor. When a display uses eDP, it requires a host board with a matching eDP connector and support, and will not plug into a standard external output such as HDMI.

HDMI

HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.

I2C

I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.

IPS

IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.

LCM luminance

LCM luminance is the brightness of the liquid crystal display module, usually measured in candelas per square metre. It helps you judge whether the screen will be easy to read in the lighting conditions where your project will be used.

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.

Transmittance

Transmittance is the fraction of light that passes through a material or layer rather than being absorbed or reflected, usually given as a percentage. A higher transmittance means more light gets through, which can produce a brighter or clearer result for the same light source.
