What are the advantages and disadvantages of TFT screens? from ycbing's blog

TFT--ThinFilmTransistor thin film transistor is a kind of active matrix type liquid crystal display AM-LCD. TFT is equipped with a special light pipe on the back of the liquid crystal, which can "actively" control each independent pixel on the screen, which is The origin of the so-called active matrix TFT (activematrixTFT) can greatly increase the response time. tft lcd module，Generally, the response time of TFT is relatively fast, about 80ms, while STN is 200ms. If it is increased, flicker will occur.

And because the TFT is an active matrix LCD, the arrangement of the liquid crystal can be memorized and will not return to the original state immediately after the current disappears. TFT also improves the STN flicker (water ripple)-blur phenomenon, effectively improving the ability to play dynamic pictures. Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, but the disadvantage is that it consumes more power and costs more.
