TFTdisplays
TFT displays are a class of liquid crystal displays (LCDs) that use thin-film transistors (TFTs) at the pixel level to enable active addressing. In an active-matrix LCD, each pixel is paired with a transistor and a storage capacitor, allowing precise, individual control of brightness. A color TFT LCD adds red, green, and blue subpixels through a color filter, with a uniform backlight providing illumination.
The TFT backplane improves response time and contrast compared with passive-matrix designs and makes higher resolution
Common TFT variants are TN (twisted nematic), IPS (in-plane switching), and VA (vertical alignment). TN offers
Applications span consumer electronics (laptops, monitors, tablets, smartphones), automotive displays, and industrial instrumentation. Benefits include fast
TFT displays became common in the 1990s and remain a dominant LCD technology, though they compete with
