What is the difference between QVGA and TFT screen in a mobile???
TFT (Thin Film Transistor) and QVGA (Quarter VGA) are two terms that we commonly encounter when we look at the LCD screens of mobile phones and other small devices. They give us a quick idea of the specifications of the LCD without digging too much into the manual. These are not competing technologies though and can both be true to a single device. TFT is a construction method where the screen is made by laying a thin film of silicon on a glass substrate. On the other hand, QVGA is simply a shorthand term that indicates the resolution of 320×240. The VGA resolution is 640×480 and the QVGA resolution is exactly a fourth of that.
