Buying a New LCD TV "Tips Buying Guide"
Buying a television is a major decision. Besides, you don't treat a TV in the same manner either - especially not if it's an LCD TV. If you're in the market to buy your very first LCD TV, here are some tips you might want to keep in mind:
LCD means liquid crystal display. Find your size.
Bigger is not always better, although LCD TV screens are certainly not wimps in that department. If you want big, you can go as high as 52 inches for most brands or if you have something bigger in mind, Sharp offers a 65-inch living room wall filler.
LCD TVs that range in size from 15 to 19 inches will work well in smaller rooms such as bedrooms and kitchens. Mid-sized screens starting at 26 inches up to 37 inches are good choices for living rooms, dens and some bedrooms. Remember, too, that size is relative to price. If you want to buy bigger LCD TVs, be prepared to pay premium, particularly for top brands. Watch your budget.
Test the unit.
Look at the screen and determine if the image impresses you. Ultimately, an LCD TV is simply a large gadget - it should perform for your viewing pleasure and no one else's.
LCD Review Guide - LCD TV Ratings Step One - How do LCD Displays Work?
Basically they work initially by blocking light. The display contains TN liquid crystals that are in between two perpendicular panes of glass that have been polarized. When light shines through this crystal matrix from one end out the other the intensity of the light is controlled and managed by the display. Displays with higher LCD TV ratings will manage this intensity more effectively. The variable voltage of the electrical charge that passes through will untwist the liquid crystals to vary the intensity of light in order for that light to pass through the second polarized pane. Higher LCD TV ratings will have a greater dark to light ratio.
The size of the display is difficult to manufacture in regards that more pixels and transistors must be added. Advances in the manufacturing process has lead to more affordable large displays.
The display can control the full spectrum of light to create the proper color. All the colors in the spectrum is achieved by dividing each pixel into three sub-pixels of red, green and blue that work together to calculate the pixel's overall hue. Each sub-pixel can range over 256 shades of intensity. Displays with higher LCD TV ratings will have lower amount of bad pixels which is caused if there is a problem with one of the transistors. The higher the resolution of the display the higher the amount of transistors the display contains since you are combining the 3 sub-pixels with the resolution.
The active-matrix inside LCD TV displays use TFTs, transistors and capacitors arranged in a matrix on a glass substrate which send electric signals down columns to the destination pixel.
