Laptop Monitors: Backlight CCFL & Wireless Antennae

Now we explore backlight a little more thoroughly.  The backlighting has what’s called CCFL which stands for Cold Cathode Florescent Light.  CCFL uses electron discharge and florescence to emit light.  Its evenly distributes the light, has more electricity, warmer temps, and last longer but is also less bright and less expensive on an LCD and the opposite on an LED. The wireless antennae provide a much larger surface area than a standard single prong-shaped wireless antenna; it is actually a long, thin component laid out the entire circumference of the laptop. The wireless antenna sits just below the surface in order to capture wireless signals from any direction or orientation the laptop may be positioned in, in order to maintain a constant connection. So the wireless antenna in a today’s laptop is actually a component of both the monitor as well as the bottom keyboard level of the laptop.
