What does LCD TV mean and how does it function? LCD stands for liquidcrystal display. Behind the screen are a number of pixels followed by afluorescent light. When this light falls on the pixels, an electriccurrent is generated, creating light variations, which make up thevividly colored images that we see. Generally, the twisted nematicliquid crystal is used which has a naturally twisted crystallinestructure.The screen size of an LCD TV varies between 13-46 inches and it isabout 2 inches deep in thickness. They are very light and so extremelyeasy to install. This indicates that they require very little space andcome with a very sleek look. In fact, they can very well be compared tothe fragile beauty of a woman!Next is the consideration of the `burn-in` factor. LCD TVs are notsusceptible to `ghosting` which results due to premature dying out ofthe pixels. The uniquely twisted crystals do not allow `burn-in` or`ghosting` to happen. There has been a marked improvement in the refresh rate or responsetime of LCD TVs. Previously, the images tended to lag behind and stayon screen for a period of time that was much more than necessary.Recent technological advances have put all that behind. Usually, theresponse time varies with the size and quality of the LCD TVs.The contrast ratio in the more advanced LCD TVs is 1000:1. The contrastratio is measured by the ratio between the brightest white to thedarkest black. The scenario has improved here too. Research is on topush the ratio well past the 1000:1 mark. Sixty-thousands hours is the average life span of an LCD TV. So at anaverage viewing of 8 hours a day, an LCD TV should last for about 20years. The life span of an LCD TV is dependent on the back-light. Sinceit uses a liquid crystal, there is nothing else which can wear outother than the back-light. Technology has found a way around thisproblem by creating replaceable back-lights as well.Power consumption, which is perhaps a very important aspect, has adefinite advantage in case of LCD TVs. LCD TVs utilize fluorescentback-lighting and so power consumption is low and steady. LCD TVs are unaffected by changes in air pressure. This makes it afavorite among air travelers. The performance is consistent and thepicture flawless, regardless of the altitude of the airplane. There is much talk about mercury being used for the fluorescentlighting. But, the manufacturers will vouch-safe for the fact that anominal amount of mercury is used. This mercury does not come incontact with the viewer and so is entirely harmless.Some manufacturers are trying to incorporate picture-in-picture featurein their monitors. This feature enables a viewer to see one program onthe full TV screen while a few other programs can run in small windowsin it. The viewer gets the added advantage to watch a particularprogram, while waiting for the intermittent advertisements to end inanother window.Experiments are on to extend color reproductions in LCD TVs. The ideais to use two back-lights with slightly differing intensities of colorsin consecutive frames. This will enable the viewer to experience abetter and a more vivid picture using a more precise color variation. An LCD TV is a whole new experience, the flavor of which can be savoredonly by purchasing one. The advantages are manifold and the experienceis just exotic. Indulging in one is a worthy bargain.
