TFT Displays

Colours are also very important in the world of displays. The well-known RGB colour scheme (red, green, blue) has been refined with TFT display technology. 8 bit gradations can be selected for each colour. TFT displays are based on LCDs (liquid crystal display). The liquid crystals in a TFT are arranged according to different systems. These include IPS (in plan switching), VA (vertical alignment), MVA (multi vertical alignment) and TN (twisted nematic). In order to manage the high number of individual pixels, an active control principle was implemented using TFT technology (thin film transistor). The latest TFTs have a resolution of up to 8K (7680 x 4320 pixels) and display 16 million colors. Thanks to the large, highly efficient production facilities, TFT displays have an excellent price/performance ratio.
