TFT vs. LCD: Know the Difference
By Shumaila Saeed || Published on February 10, 2024
TFT (Thin Film Transistor) is a type of LCD (Liquid Crystal Display) with improved image quality and response time; LCDs are display devices using liquid crystals for image formation.
Key Differences
A Thin Film Transistor (TFT) is an advanced form of Liquid Crystal Display (LCD). While both use liquid crystals, TFT technology involves using transistors for each pixel, enhancing image clarity and response time.

TFT displays, being a subtype of LCDs, offer higher resolution and faster response times. This is because each pixel in a TFT is controlled by individual transistors, whereas traditional LCD screens use a passive matrix technology.
