Polarizer - liquid crystals and colour filters - for liquid crystal display (polarizer - liquid crystals and colour filters production - for liquid crystal display)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This product is used in the production of a liquid crystal (LCD) display. A polarizer controls the brightness of the pixels of a liquid crystal display while the colour filter filters the backlight in such a way that the required colour is projected on the screen. Main data are based on information in a US-EPA LCA study about LCD and CRT production. The data represent the respective efforts for a 15-inch LCD computer screen as it is produced in Japan in the late 1990s. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
