Indicates whether the product includes a built‑in screen or display unit that can be used directly for viewing content, such as an integrated monitor on a laptop or a built-in display on appliances. A value of "Yes" means the device has such a display; a value of "No" means it does not.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The operating frequency of a device or component, expressed in hertz (Hz). It represents the number of cycles per second that the product’s internal circuits or wireless radios can run and is useful for comparing performance across similar products.

The IP (Ingress Protection) code indicates a product’s resistance to solids and liquids. It follows the standard two‑digit format (e.g., IP20, IP67), where the first digit represents protection against solid particles and the second against liquids. The code may include an ‘X’ to denote unknown protection for that category or multiple codes separated by commas for products offering different levels of protection in various configurations.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.
