Recent years have seen the growing popularity of LCD TVs. They offer a slim lined device that looks great in our living rooms and can offer a much better picture. But how do they work?
An LCD TV is a flat-screen televisions based on liquid crystal display that has other active properties of both liquid crystal and light. The crystals are nothing but molecules are cylindrical, which allow light to pass through them during the crowd. This untwisting of molecules depends on the amount Gift electric field. The greater the amount of electricity the greater the untwisting of molecules and the greater the blockage of light rays. Therefore, varying the amount of current, light intensity can be varied.
Liquid crystal technology is used nowadays many electronic products such as video camera, Display screen digital camera, mobile phone screens and computer monitors. LCD TVs are designed specifically to view video images. Screensize LCD TVs can range from 13-100 inches. When compared with plasma TV, they are much lighter and more durable.
An LCD TV is made liquid crystals that are placed between two polarizing filters and two transparent electrodes. The work of the electrodes is to access each crystal and control of electrical flow. The LCD crystals are unable to produce light, so they are supported by external light source that causes them to become visible to the viewer. Each molecule or crystal behaves as a limiter, which limits the light to pass through them, depending on the voltage supplied. So for bright display voltage is kept low and the voltage dark details is kept high.
Since LCD technology does not require electrodes to stimulate extra phosphorus in relation to plasma, therefore they are much thinner and lighter in weight. LCD technology is also called non-deliverable and eco-friendly which means it does not emit any harmful radiation.
Due to the characteristics mentioned above, LCD TVs are gaining immense popularity despite being expensive and had become a very popular choice for home theaters and seeing TV.
