| - | A screen can be described as a **graphical interface** which converts electronic signals to a displayable form for the end-user. The technology consists of pixels that have been laid out in a matrix and can be controlled independently to display texts, images, or video sequences.

| - | The scope of this life cycle assessment study involves the complete screen unit, encompassing the screen panel itself. This also extends back to upstream production processes such as the mining and refinement of materials used to create the screen, as well as the manufacturing of sub-units such as backlighting and the screen glass. Distribution is considered as part of the perimeter as it involves transport from the manufacturing facility to the end-user. | + | The scope of this life cycle assessment study involves the complete screen unit, encompassing the screen panel itself.
