Thin film transistor liquid

Thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin-film transistor (TFT) technology to improve image quality (e.g., addressability, contrast).

LCD produces high image quality. They can be made very thin, which makes them less space-consuming, and the user can hang them anywhere. This makes them appealing to buyers.

LED screens are actually very much like LCD's. They also have a flat-screen which utilizes Liquid Crystal Display technology. The only difference is their source of light, which is at the back of the screen. The LCD uses fluorescent lamps, and the LED uses LED (Light Emitting Diodes).
