TFT, e kgutsufaditsweng bakeng sa Thin-Film Transistor, e bolela matrix ya di-transistors tse nyane haholo. Ho fapana le dipontsho tse tlwaelehileng, pixel ka nngwe hoTFTSkrine e laoloa ka bonngoe ka sistimi ea "matrix e sebetsang". Molao-motheo oa ts'ebetso o tšoana le mokhoa oa "shutter": ho sebelisoa theknoloji ea backlight, li-transistors tse inehetseng ka mor'a pixel ka 'ngoe li laola phetiso ea leseli ka ho laola ho hokahanya kristale ea metsi, ho fihlella 'mala o nepahetseng le tlhahiso ea khanya.
