The Benefits of LCD TVs

LCD displays are surrounding people every day whether they are at home, school or perhaps at work. Liquid crystal displays are so common that many people can’t last a day without using one. This technological innovation can be found in car dashboards, calculators, thermometers, stereos, microwave ovens, digital clocks and bathroom scales. This technology can be applied anywhere and it is no surprise that it reached the basic home appliance- television set. Liquid crystal technology has indeed given birth to slim, nice looking and bright displays that are emerging almost everywhere from hotel lobbies to living rooms.

So how do LCD TVs work?

The most popular type of liquid crystal used in display apps today is the twisted nematic crystal. This type of liquid crystal reacts with electrical currents in a predictable manner- by untwisting to different degrees based on the voltage that has been exposed to it Launch creader Crp129x.

The kind of backlighting is also a determining factor in what consumers today call LED TVs. The traditional backlighting that has been used until today has always been CFL fluorescent backlighting. The past few years, it has already upgraded into a brighter and more luminous LED or light emitting diode technology. These LCD televisions embedded with LED backlighting are still considered as LCD TVs but there are others who have tagged them as ‘LED TVs’ just to give more emphasis to its LED backlights.

What are the advantages of LCD flat screen television sets?

· Brighter & higher contrast. Flat screen TVs such as plasmas, LEDs and LCDs appear brighter and have higher contrast compared to the classic CRT sets. LCD TVs usually perform well under ambient lighting conditions. A good thing about flat screens is that you do not need to switch off the lights for you to view images vividly and easily. You don’t have to worry about eye strain either since neither plasmas nor LCDs flicker the way old television sets do. LCD TVs have also made innovations lately with the use of LED backlighting systems that allows for better black levels and are more energy efficient.

· Dot pitch and viewing angles. You can now watch TV from anywhere in the room as LCD displays may have up to 160 degrees viewing angle- this only means that your TV will still look good when viewed from any point eighty degrees in either direction from the center of display. Dot pitch refers to the total distance between sub pixels of similar colors in adjoining triads. The closer these dots are to one another, the sharper image resolution it produces. High dot pitch units can also increase the panel’s viewing angles. As a general rule, smaller dot pitches make sharper images. TV plasmas have long been acclaimed for their wide viewing angles compared to LCD units. But modern improvements have already made LCD televisions comparable to the plasma units when it comes to viewing angles.

· Smooth, bold, colorful and high quality images. Flat screen TVs don’t have the annoying scan lines that can often be found in conventional sets. Each sub pixel has its own transistor electrode that creates smooth and equally lit images throughout the entire display surface. Many of the current advances in LCD TV technology have remarkably increase display response times which results to smother on screen presentations.
