2.1 WHAT IS LCD ?
●LCD means Liquid Crystal Display. Liquid Crystal is neither in Solid state nor in fully Liquid state. (Example: Like soapy water)
●Liquid Crystal when stimulated by an external electrical charge, can change the properties of light passing through the crystal.
●LCD are the Passive Display Device.
●LCD does not emit its own light, therefore artificial light is required to produce desired level of light passing through each cell or it needs ambient light.
●By manipulating this external light a display is produced at very low power consumption.
