Home > Technology     TFT-LCDs consist of a lower glass plate (TFT formation), an upper glass plate (Colorfilter formation), and an injected liquid crystal between both glass plates. The TFT plays a role in transmission and electric signal control, which determine the level of voltage applied to the liquid crystal.   Special Features | Manufacturing Process | Technology Forecast   IPS  |  Cu bus line  |  LTPS  |  ODC  |  Glass Etching  |  Side-Mounting  |  Colum Spacer |  Reduced the number of mask step |  BCB Technological innovations in the LCD industry occur at a faster pace than in any other industry. In response to the rapid technological developments in the flat panel display industry, LG Electronics' Central Research Institute conducted research on TFT technology in 1987 and later established the Anyang R&D Center in April 1990.
