LCD TVs

The decorative and romantic world of flat panel TVs and plasma TVs get a new dimension with the ingress of LCD TVs, or liquid crystal display TVs, in the home entertainment industry. Theydeserveit takes you for a journey round the slim display of LCD TVs.

LCD TV is a flat and thin device made of a number of colored or monochrome pixels aligned in front of a reflector.


Due to its usage of small amounts of electric power, it is highly prized by engineers and is considered suitable for use of battery-powered electronic devices. The pixels in the LCDs consist of a layer of perpendicular molecules lined up between two transparent electrodes, and two polarizing filters, the blocs (axes) of polarity of which are perpendicular to each other.

The liquid crystal material and the alignment layer material contain ionic compounds and if this ionic material is attracted to the surfaces, it degrades the device performance. One can avoid this by applying either an alternating current, or by reversing the polarity of the electric field. Each individual pixel of LCDs is divided into three-sub pixels colored red, green, and blue, respectively, by additional filters and can be controlled independently to produce thousands or millions of colors for each pixel.

Modern LCD TVs use an active matrix structure for High-resolution color displays. Few of the drawbacks of LCD technology are:

  • LCDs produce crisp images and the attempts to run LCD panels at non-native resolutions usually result in non-native resolutions in the scaling of the image leading to blurriness.
  • LCDs have more vibrant images and better contrast ratios (which is the difference between a completely on and off pixel). LCDs produce "backlight bleed" when light leaks out and turns black into gray.
  • Many LCDs fail to display as many colors as their plasma counterparts
  • LCDs have longer response times compared to the plasma counterparts
  • Some LCD monitors may lead to migraines and eyestrain problems due to fluorescent backlights fed at 50 or 60 Hz.
  • Many LCDs are incapable of displaying very low-resolution screen modes like 320 x 200. This happens due to scaling limitations.
  • Consumer LCD monitors are more fragile than their plasma counterparts.


Normally LCD TV screens are in the range of extra large, large, medium and small screen. Here we bring to you a list of LCD TVs by few of the best manufacturing houses in the industry:
