Liquid Crystal Display is all about flat panel tv technology. The innovation of liquid crystal screen has actually penetrated our daily life in everyday things like wristwatches, mobile phones, calculators, computer monitors and high definition television. The use is growing rapidly and sales of LCD television are expected to go beyond 4 million in America alone.
There are some distinct advantages of LCD panels over other sort of display screen innovations. They are slimmer and barely surpass 3.5 “in depth. These are lighter also and most importantly they draw less power – just about 60% of the power consumed by plasma displays. LCD tvs do not spew electromagnetic waves that are damaging.
There are drawbacks obviously – seeing angle is restricted, contrast ratio is minimal and time of display response may trigger issue. The greatest frown of all is caused by the rate. Although it is falling but still it is considerably higher than its plasma equivalent.
LCD display screens consists of mainly of sheets of polarized glass sheets – two in number. A liquid crystal service is sandwiched in between these. These liquid crystals are very specific that causes them to function as shutters that open or shut out entry of light as the requirement occurs depending upon flow of electric current. This current passing through the liquid crystals is controlled by voltage that is applied in between the glass sheets through the electrodes that are transparent. These form a network having rows on one instructions of the panel and columns on the other side representing the pixels or photo aspects.
What are these liquid crystals? There are substances that exist in a state that is neither liquid nor strong at any one point of time. Thus these liquid crystals can be called neither liquid nor strong though they have more of an affinity for the latter – that is the liquid state.
There are different kinds of liquid crystals with each having its distinct homes. Those used in LCD panels are termed nematic-phase liquid crystals. The particles are set up in a particular fashion having distinct pattern.
LCD display systems are of two types – passive and active matrix. A typical wide screen panel will need 3.1 million transistors. Any one malfunctioning transistor can not be changed and are known as dead or stuck pixels.
It was throughout the early 2000’s that LCD flat panels took over the television market from the common CRT’s. The basis of the innovation is founded on the attributes of polarized light. The thin semi liquid crystal gel caught in between 2 slim polarized sheets is divided into pixels.
There is hectic activity to get rid of the technological problems to make the set economical. The LCD TV has actually to be made economical to hit the headings of success.
