Character readers are those devices which read the characters printed on the source documents and then convert them directly into computer usable input. LCD is not a character reader.

LCD (liquid crystal display) is the technology used for displays in notebook and other smaller computers. Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology.
