Why are LED lighting devices better than the traditional ones?

There is a continuous innovation in the display technology. The cathode ray tube based TVs or computer monitors are now giving way to the more advanced display lighting systems. These are the modern day liquid colour display and the light emitting diode technology based display lighting technologies. Companies like Sony are now fast outdating the CRT based display with the flat screen, practical LCD TV or the LED lighting technology based displays.

What makes LED so special? Why is its usage fast outstripping the demand of the CRT displays? There are many advantages which come with the LED. Some of these are the following:

1.Widespread use: LED lighting has been there for some decades now and is therefore a proven technology. Its use is not confined only to the TVs or ,monitors but is also being used extensively in different electronic and lighting devices like bulbs, telephones, and others.

2.Aesthetic appeal: The LED device creates a glow which is very soothing and warm. The earlier LED lighting devices produced a little harsh glow but this is not the case with the new ones. Technology has improved to produce the warm and soft glow.

3.Energy-efficient: This is one of the greatest benefits of these devices that these consume less power to produce the same type of lighting brightness. This not only saves you money by reducing your electricity consumption but also saves the energy.

4.Long lasting: The LED based products have greater life. Whether it is the bulbs or the TVs or even the monitors, the LED products are long lasting. These can work without glitch for years. You do not have to be in trouble for replacing them often as in case of the incandescent bulbs. These are also better than the CRT based TVs who had this problem of malfunctioning tube. The modern LCD TV have life in tens of thousands of hours.

5.Score over CFL: You must not confuse the LED with the CFL lighting devices. The latter contains mercury which makes it necessary to handle it with extreme care. The presence of mercury makes them dangerous to use. These are therefore very environment unfriendly.

6.Do not heat up: The LED lighting devices does not heat up even after using them for several hours. The incandescent lights and the CFL can get hearted within a few minutes but not the LED ones.

7.Constant light throughout their life: The light of the LED devices is of same intensity all through their lifetime. These do not get dim. In fact, they fade only when these are at the end of their very long lifetime.

All these factors make the light emitting diode based lighting devices extremely popular, especially among those who want to reduce their monthly electricity bills as well as are conscious of the damage to environment. These might be more expensive than the traditional ones but when their advantages are considered, these are found to be more practical.

Unfolding the display technology innovations: from LCD TC to SED TV

You would have often come across the terms ‘LED’ and/or ‘LCD’ while buying or speaking about the TVs, computer monitors or other display devices. The LED is the short form of the light emitting diode, which is an electronic component that is used in the electronic instruments for displaying light. The LCD refers to the Liquid Colour Display, which is a technology in which the use is made of the liquid crystals to provide display of different colours. The LCD TV was an improvement over the old cathode ray tube (CRT) based TV.

A LCD TV was more practical and provided and better viewing quality than the CRT based TV. These are not thick and bulky, like the old CRT TVs but, on the contrary, these are slimmer and flatter than the traditional ones. These make use of the cold cathode fluorescent lamps for backlighting purposes. This is where the main difference between the LCD and the LED TV lies. The LED lighting from behind the screen is done, not with the fluorescent bulbs but with the light emitting diodes.

This small technological change has redefined the viewing quality of the TVs which have since then become flat panel, use less of power and offer better contrast ratios. The more recent technological change has been to use the SED technology, or the surface conduction electron-emitter display technology. These imbibe the qualities of the CRT TVs and the LCD displays. So, these offer you wide display angles, higher contrast ratios, wider viewing angles of the CRT TVs and thin and slim features of the LCD TV.

Major electronic companies of the world have been producing the LED displays for different uses for a long time now. In fact, the popularity of the LED lighting displays made by top companies like Sony, Samsung, Toshiba and others has risen considerably. The total number of LCD TVs sold in a year has now been able to breach the yearly sales figures of the CRT TVs.

Another popular change has been the evolution of high definition high resolution audio-video formats. The use of high definition audio and sound quality has tremendously improved the audio and video quality. The use of special cables to connect the various devices, which support the high definition pictures and audio quality, have been able to deliver error free and undistorted quality. The high definition DVD, also called the HD DVD, stores the high resolution data and the DVD player sends these signals through the HDMI cables to the LED display networks.

The innovations in the display technology and the improved functionality of the systems making use of the high definition sounds and pictures has made possible the theatre experience to come right in your homes. Aptly called the home theatre, the system make use of the HD LCD TV, HD DVD players and HDMI connecting wires, apart from other devices like the speakers, amplifiers, etc.
