Q: How do LCDs compare to CRTs in terms of radiation?
Because LCDs do not use an electron gun, they do not generate the same amount of radiation at the

Q:
What is a Liquid Crystal Display?
A Liquid Crystal Display (LCD) is an optical device that is commonly used to display ASCII
A:
characters and images on digital items such as watches, calculators, portable game consoles, etc. LCD
is the technology used for displays in notebooks and other small computers. Like light-emitting diode and
gas-plasma technologies, LCD allows displays to be much thinner than cathode ray tube (CRT)
technology. LCD consumes much less power than LED and gas-displays because it works on the
principle of blocking light rather than emitting it.
Q:
What differentiates passive matrix LCDs from active matrix LCDs?
An LCD is made with either a passive matrix or an active matrix display grid. An active matrix has a
A:
transistor located at each pixel intersection, requiring less current to control the luminance of a pixel. For
this reason, the current in an active matrix display can be switched on and off more frequently, improving
the screen refresh time (your mouse pointer will appear to move more smoothly across the screen, for
example). The passive matrix LCD has a grid of conductors with pixels located at each intersection in
the grid.
