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

The activity generating the emissions is polarizer, liquid crystals and colour filters production, for liquid crystal display. The reference product is polarizer, liquid crystals and colour filters, for liquid crystal display. 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 reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
