How does a TFT Display or Active Matrix Display work?
The difference between TFT displays and LCD displays is now clear, but how does TFT technology work? TFT stands for Thin Film Transistor. For each RGB sub pixel there is a transistor integrated into the glass. These sub pixels can therefore be individually controlled and turned on and off. This allows development and production of vibrant color images, with high resolutions. In addition, the response time of a TFT is faster, making it interesting for many manufacturers.
A TFT is made by combining a thin film of a semi-conductive active layer with a layer that acts as an electrical insulator. They are laid on a supported under layer together with metal contacts.
An LCD pixel is then actively controlled by one to four transistors. By adjusting the voltage, the transistors turn the pixels on and off easily. Red, green and blue color filters are placed on the inside of the top glass to show the color information. The intensity of light transmission is controlled by color filters. As a result, millions of colors can be displayed on one screen.
The embedded TFT layer on the screen reduces crosstalk between pixels. Crosstalk occurs when a signal sent to a pixel, also affects the pixel next to it. This makes TFT display technology the technology that offers the best resolution and image quality. TFT’s are therefore more expensive than regular LCD’s.
TFT displays have become todays standard in producing LCD monitors.
