FAQ

1.What is the difference between LCD and TFT display?

LCD: liquid crystal display. Works by adjusting the amount of light blocked. Usually has a backlight but might not (clocks, calculators, Nintendo Gameboy). ... TFT: is a type of LCD with a thin film transistor attached to each pixel.

2.Which is the best display type for mobile?

IPS-LCDs are costlier than normal TFT LCD and hence are found only on higher end smartphones. A higher resolution (640 x 960 pixels) version of IPS LCD is used in Apple iPhone 4 and is called Retina Display because of its brilliant picture quality. Touchscreen LCD displays are of two types – Resistive and Capacitive.

3.Which one is better TFT or LCD?

TFT stands for "thin-film transistor." LCD stands for "liquid crystal display." Both terms refer to the flat-panel display, or screen, of a computer monitor or television set. A TFT display on a computer monitor is brighter and faster than a regular LCD display.

4.How does a TFT screen work?

TFT displays or thin film transistor displays utilize simple chemical and electrical properties to create a visible image on a screen. Utilizing an electrical charge that causes the liquid crystals to change their molecular structure allowing various wavelengths of backlight to “pass-through”.
