Do all LCD screens use TFT screen technology?

I am Wondering if all LCD screens are TFT? Will LCD screens ever go away?

    No, there are several different LCD technologies in use.

    TFT (thin film transistor) is one of the commoner types, for larger / higher resolution types.

    IPS (in-plane switching) & variation on that technology are very common - that presently has the widest viewing angle range.

    TN (twisted nematic) is still also very common in smaller LCDs and cheaper monitors/screens. They are cheaper to manufacture but have limited viewing angle range.

    LED screens are just one of the LCD types with LED rather than fluorescent backlighting.

    OLED & it's variations (AMOLED etc) which are now becoming commoner are totally different and unrelated to LCD types.

    With those, each pixel is made up from individually controlled LEDs

    It has a lot of possibilities but is still relatively new and still has some problems, such as areas of a display that are often very bright age and fade more, leaving ghost images similar to CRT "burn-in" in appearance.
