TFT display is the technology used on most modern flat-panel monitors and screens. Mobile phones, computer monitors, and flat screen televisions with LCD screens likely use TFT display technology. TFT stands for thin film transistor, and it allows for the creation of ultra-thin screens with displays that update faster than before.
Thirty years ago, the only screens available for use with computers or televisions used cathode ray tubes (CRT). This is the original technology used in televisions. While it worked for decades, the large, bulky size of the screens kept monitors and televisions comparatively small. These monitors also did not use digital technology and became hot with extended use.
TFT display screens use a single transistor to operate each pixel in the display. Larger screens with higher resolution will have more pixels and more transistors in a TFT display. Since each pixel is operated individually, minute changes in the screen can quickly take place. This is most noticeable with TFT screens used on mobile phones or computers. Changes on the screen like movements of the pointer or typing letters appear instantly on the screen, without lag time or vague disappearances of the cursor.
Liquid crystal display (LCD) screens using TFT technology are some of the best available today. TFT displays allow for sharper images, thinner screens, larger displays, and cooler operation. This technology is found in most of today's LCD screens. Pick those with the fastest update times for the best, clearest display.
Old CRT televisions and monitors are only good now for boat anchors or paper weights. Digital technology and portability demand the use of thinner, lighter screens that use TFT technology.
