TFT
|
Also called active matrix, TFT is short for thin film transistor. It refers to a type of flat panel liquid crystal display in which each pixel is controlled by one or more transistors (typically 4). A thin TFT uses a thin film of silicon (as opposed to a MOSFET for example, which uses a much thicker silicon wafer) to transfer current. Light must pass through this silicon film that makes up the picture on the display, and each thin film transistor corresponds to each pixel. A current is used to turn on and off the transistor, which in turn controls the light that's passed through the film.
Some of Sony's flagship models feature a 32,000-color TFT display, with a 96 x 400 resolution, adding up to 38,400 pixels in 15-bit color - pretty close to what you'd expect to find in the best laptop computers or wide screen HDTV's. Visual feedback never looked so good in a car audio context, rivaling the best in home A/V offerings. Many of these visually stunning models offer full customization of the image displayed on the TFT display, including images from your digital camera, or even the moving image from your DVD player. In some models, you can even capture a still image from the DVD, and use it as the unit's permanent wallpaper! Related Technologies Active Matrix LCD Widescreen |
