Longer life for LCD screens is now possible thanks to two types of glass developed by German glass tube manufacturer Schott, the company said on 31 August 2004. The two glass types have a filtering effect on UV rays which protects the plastic components from premature ageing. Flat-screen displays have a limited life because the ultraviolet radiation emitted from the backlights damages plastic components inside the screen. The UV radiation responsible for the damage to the plastic components occurs in the invisible wavelength spectrum between 254 and 313 nm. Schott has managed to incorporate a UV filter for this frequency range in the two new glass types so that no complex coating is necessary at a later stage.
