Simply so, what does LCD mean on a TV?
liquid crystal displays
Secondly, what is the difference between LED and LCD TV? An LED TV uses a liquid crystal display (LCD) panel to control where light is displayed on your screen. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.
Also question is, which is better LED or LCD TV?
LCD TV vs. LED TV. An LED TV uses less power, provides a brighter display with better contrast, a thinner panel, and lesser heat dissipation than a conventional LCD TV. This is because an LED TV uses light-emitting diodes for backlighting as opposed to the CCFLs of conventional LCD TVs.
How does a LCD TV work?
Flatscreen LCD and plasma screens work in a completely different way. In a plasma screen, each pixel is a tiny fluorescent lamp switched on or off electronically. In an LCD television, the pixels are switched on or off electronically using liquid crystals to rotate polarized light.

Why are LCD screens polarized?
An LCD has two polarized layers on top of each other. Normally they are both polarized in the same way, so that light gets through both layers just fine. When the voltage is applied, the crystals' polarization shifts so that it is at 90 degrees with respect to the second layer, and no light gets through the layers.How can I fix my LCD screen?
