Terms used on this page (5)
- ppi
- Pixels per inch: how densely pixels are packed on the screen.
- Nits
- A unit of screen brightness (candela per square metre). Typical, HDR and outdoor peak figures are measured under different conditions.
- IP rating
- Ingress protection under IEC 60529: the first digit rates dust protection, the second water protection, each under the manufacturer's stated test conditions.
- mAh and Wh
- Battery capacity. mAh is charge; Wh also accounts for voltage, so it is the more comparable energy figure across device types.
- LTPO
- A display backplane technology that lets the refresh rate vary, down to low rates to save power.
