A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously.

The display technology. Flat screen technologies like Liquid Cristal Display (LCD) and Thin Film Transistor (TFT) active matrix technology are the trend. In TV technologies one can notice FST (Flat Screen Tube) technology, and ARASC (Anti Reflexion, Anti Static Coating) or AGARAS (Anti-Glare ARASC) or simply AGC (anti-glare coating). The old tv and screen technology CRT means Cathodic Ray Tube. MLA = Micro Lens Array. p-Si=Polycrystalline Silicon. a-Si=Amorphous Silicon.

Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The wireless interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2.
