What is TFT and What is LCD?


Published by JFCVision April 11,2019

TFT is a variant of LCD, TFT "Thin Film Transistor" is one of the active matrix type liquid crystal displays AM-LCD,

The TFT is provided with a special light pipe on the back of the liquid crystal, which can "actively" control the individual pixels on the screen,

which is the origin of the so-called active matrix TFT (AcTIve Matrix TFT), which can greatly improve the reaction time. 

Generally, the reaction time of TFT is relatively fast, about 80ms, while STN is 200ms. If it is to be improved, there will be flickering.

And because TFT is an active matrix LCD, it makes the arrangement of the liquid crystals memorable and will not be restored immediately after the current disappears.

The TFT also improves the STN flicker (water ripple)-blurring phenomenon, effectively improving the ability to play dynamic pictures.





Compared with STN, TFT has excellent color saturation, reducing power and higher contrast, but the disadvantage is that it consumes more power and costs.

LCD: Liquid Crystal Display, mainly divided into: monochrome, pseudo color, true color and so on. TFT is a kind of LCD, also called true color screen.

The brightness and viewing angle are stronger than the other two!

LCD refers to liquid crystal display, TFT is a kind of LCD

Common liquid crystal displays are classified into four types according to their physical structure:

   TNTwisted NemaTIc

   STNSuper TN

   DSTNDual Scan Tortuosity Nomograph

   TFTThin Film Transistor


 TFT-LCD display


The basic display principles of TN-LCD, STN-LCD and DSYN-LCD are the same, except that the twist angle of the liquid crystal molecules is different.

The liquid crystal molecules of the STN-LCD have a twist angle of 180 degrees or even 270 degrees.

The TFT-LCD uses a display mode that is distinct from the TN series LCD.
