Did you know that there are seven generations of TFT-LCD technology? Apparently so, and from Autumn 2007 there will be an eighth.
Sony and Samsung have signed a final contract and jointly invested $1.9bn into constructing a new production plant at S-LCD (Tangjeong, ChungCheongNam-Do, Korea), capable of producing panels with a glass substrate size of approximately 2,200mm×2,500mm.
This will allow the production of 50 iinch LCD TVs.
If you like numbers, here's a comparison of 7th and 8th generation screens:
- For 7th generation (1,870mm×2,200mm): 6 panels for 46 inch TV, 8 panels for 40 inch TV, 12 panels for 32 inch TV
- For 8th generation (approx. 2,200mm×2,500mm): 6 panels for 50 inch class TV, 8 panels for 46 inch TV
This should help to meet the increasing demand for larger-scale LCD screens.
