The underlying display panel technology used in a visual device, such as IPS, TN, VA, OLED, AMOLED, or other variants. It indicates the type of liquid crystal arrangement or organic light‑emitting structure that determines image quality, color accuracy, viewing angles and power consumption.

The number of pixels per inch on a display, expressed as points‑per‑inch (ppi). This metric indicates how sharp and detailed the screen appears, allowing comparison across monitors, smartphones, tablets, and other pixelated devices.

Represents the physical size of a single pixel on a display, expressed as width and height in a length unit (e.g., millimeters). This attribute allows comparison of the physical resolution of screens or imaging devices that use metric units to describe the smallest visible point.

The time interval between a stimulus and the corresponding response of a device or system, expressed in units such as milliseconds (ms). It indicates how quickly the product reacts to input or processes data, which is critical for performance-sensitive applications like displays, gaming monitors, and interactive devices.
