LCD-TV – The latest ads

Liquid Crystal Display technology is all about flat-panel TV. The technology of liquid crystal display has penetrated our everyday life in everyday things like wristwatches, mobile phones, calculators, computer monitors and high definition television. The usage is growing rapidly and sales of LCD TVs is expected to more than 4 million in America alone.

There are some distinct advantages of LCD panels over other display technologies. Youare more narrow and difficult to move forward, 3.5 “ in depth. These are the easiest and best of all draw less power – only about 60% of energy consumed by plasma displays. These televisions do not spew electromagnetic waves that are harmful.

Of course there are drawbacks – limited viewing angle, contrast ratio is limited and the response time display can relate to. The largest of all the frown is caused by the price. Even if it is, but it is much higher than theirPlasma counterpart.

LCD is composed mainly of layers of polarized glass sheets – two in a row. A liquid crystal solution is trapped between them. These liquid crystals are very specific cases such as open, or close the shutters outside the entrance of light, if necessary, depending on the flow of electric current to act. This current through the liquid crystal voltage, regulated by the electrodes between the panes of glass, which is usedtransparent. These form a network of lines representing a direction of the panels and columns of pixels on the side.

What are these LCD? The material can be determined in three states – liquid and gas are found. However, there are substances to exist in a state that is neither liquid nor solid at any given time. The behavior of these molecules is unique. They keep their orientation, as in a solid, yet around shuffleThe inclusion in various positions, such as molecules of a liquid. These are called liquid crystals or solids or liquids, although they tend to have an affinity for the second – which is the liquid state.

There are several types of liquid crystals with each having its distinct characteristics. These panels are used as LCD-Liquid Crystal nematic phase. The molecules are arranged in a special way with distinctive patterns.

LCD display systems are composed of twoTypes – active and passive matrix. The first is more complicated, produces the best pictures and consequently increases the price. During the manufacture bad points are a serious problem. Numerous control transistor on glass substrates are provided for each sub-pixel control. A typical wide screen panel requires 3.1 million transistors. Each transistor can not be replaced defective and are known as dead spots or dark spots. If your system is definitely a black spotShow and then indicating whether a white spot. If there are a number of the whole group will be crossed out.

It was during the early months of 2000 that LCD panels s. took the CRT TV market in the typical "The technology exploits the properties of polarized light is created. The gel thin semi-liquid crystal between two sheets of thin polarized captured divided into pixels.

There is frenetic activity on the technological difficulties to be overcomeaccessible to the masses. Thus, the LCD TV will be made accessible to the success of the first page.
