The regulation specifies in Article 1 (2) point (g) that displays that are components or sub-assemblies as defined in point 2 of Article 2 of Directive 2009/125/EU are excluded from the scope of the regulation. This exemption was intended to apply to displays integrated in other products. However, it is not specified whether displays provided as spare parts shall be considered out of scope of the Regulation.
Displays integrated in other products can be considered as components or sub-assemblies, and therefore excluded from the scope of the Regulation if their environmental performance cannot be assessed independently as stated in point 2 of Article 2 of Directive 2009/125/EU.
It is irrelevant whether a display is commercialised as 'component or sub-assembly', 'spare part', 'display tile' or 'integrated display'. Displays provided as spare parts are therefore exempted if for example they do not have a suitable interface for data and power which can be used by authorities for the purpose of testing or other characteristics that would prevent assessing their compliance independently of the product they are to be integrated in. In short: if a display falls under the scope of the regulation and can be tested separately having a suitable interface for data and power, it is subject to Ecodesign requirements, regardless of being or not connected to another product. At the same time the regulation does not apply to the components of a display, e.g. the LCD panel.
