With Thin-Film Transistor (TFT) technology applied to the display, each display pixel has its own transistors and capacitors located next to it. When addressing a particular column and individually activating each pixel in that row of a TFT display, this will ensure dramatically faster response time and greater contrast of pictures quality compared to CSTN display. Therefore, TFT screens are also called active matrix LCDs.
Ever since the first TFT display was born, the existing LCD industry has experienced fundamental changes, demands for wider viewing angle, higher resolution, high brightness, and long-life backlight, are never ending. We work closely with our TFT cells suppliers to design and manufacture high performance, durable TFT display for both custom and standard ones.

Our core competitiveness is to develop added values of high quality products and provide efficient designs service. Especially the concept of “Interactive Display” which is TFT display integrated with Capacitive Touch Panel to provide the novel and more natural ways for people to easily access and manipulate related information from the machines.

STN LCD
STN (Super-Twisted Nematic) LCD has quite a long development history, it requires less power and is less expensive to manufacture than TFT LCD. With the addition of a retardation film on top to the STN LCD (known as FSTN) that compensates for the color added by the birefringence effect, will allow FSTN display with better black and white color and provides for a higher contrast and wider viewing angle. With the RGB color strips properly made inside the FSTN display, through external white backlighting, to generate the full colors effect, it becomes a color STN (CSTN) display.

Because of its maturity and its low fabrication cost, STN LCD technologies is still popular used for the display market of most portable applications such as industrial and medical instrumentation and many other products that require small-medium size display.
 Flat-panel display technology has been developing extremely rapidly, the main advantages of STN over other display technologies is the relatively easy and economic that the display content can be customized to satisfy the specific requirements of an application. EDT is keeping the R&D resource to support our customer’s need for their future STN LCD designs.
