TFT Last modified: Tuesday, September 09, 2003

 

Short for thin film transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called active-matrix LCDs.

 

TFD

 

TFD (thin film diode) is a type of LCD (liquid crystal display) flat-panel display technology.

 

TFD technology combines the excellent image quility and fast response times of TFT, with the low power consumption and low cost of STN.

 

TFD technology is an active-matrix technology, meaning that a tiny circuit (a diode) is located next to each pixel, allowing the pixel to be turned on and off individually. This permits faster response time and greater contrast compared to passive-matrix technology.

 

Edit håper dette svarer på spørsmålet ditt har ikke tid til å oversette det men.......
