Modern LCD/LED TVs are highly practical in use

Display technology has travelled a long technological distance from the days of cathode array tube based display devices to the most modern LCD/LED/SED and plasma displays. It was only recently that the CRT TV sales worldwide were beaten by the LCD TVs signalling that the times of the CRT display are numbered and that the modern displays are being increasing adopted by the people. For the technical person, the difference between the two technologies is immense but for the consumers it is the easy-to-use and easy-to-manage nature of these appliances that matter the most. No wonder that most of the top names in the consumer electronics products are spending fortunes to be the leaders in the cutting edge display technologies.

For the layman who does not understand the meaning of these technology terms, the difference is there to be seen. The good old Samsung TV would be bulky since it has the picture tube in it but the new LCD /LED TVs would be slim and sleek with flat displays. And, you do not have to buy a trolley for keeping the new ones. These can be fixed on the walls. In this way, you save the considerable space for moving around. These are perfect for small spaces. Due their being slim, these are easy to carry as compared to the bulky ones. It is also a fact that the picture quality of these displays is better than the previous ones. This has largely to do with the high definition resolution levels compatibility of these displays and also with the use of the latest display technology.

While getting the modern slim TVs installed in the homes or office, the points of their placement are to be duly considered. These shall be placed at the right places on the walls. The placement shall preferably be straight for most of the viewers since these are not visually appealing when these are viewed from the side angles. This is one aspect where the CRT scores over the modern LCD/LED ones. CRT based Samsung TV will give the same picture irrespective of the place or angle from where you view it.

Plasma TVs are yet another innovation in the display technology. There are more long lasting than the LCD TV/LED TV ones. The only disadvantage that these currently face is that the impressions of the last images remain on the screen for a long time even after the TV is switched off. The companies are making efforts to get over this drawback.

There is no doubt that the modern TVs are an improvement over the others, both in terms of technology as well as user experience. It is also a fact that these are more practical to use. That is also the reason why most of the modern homes use these for setting up modern systems like the home theatre. These have also taken the wall space of organisations where these find good application in lobby, waiting rooms, visitor’s areas and other such area where the works not going on.

LCD and LED: Display technologies for TVs and mobiles alike

There were times when the cathode ray tube based TVs held sway. In fact, these ruled the TV display technology till the last decade of the last century when their global sales dipped for the first time against the rising sale of the LCD TV sets. All major companies of the world, which make the consumer electronic items, including Samsung, have now shifted their focus on making the more practical, slimmer, LCD/LED TV sets which are fast replacing the outdated CRT sets. The Samsung LED TV is an improvement over the LCD TV since the former uses light emitting diode for backlighting purposes, obviating the need for a tube. The result is the emergence of the visually more appealing and wall-mountable TVs.

LCD/LED technology has made it possible for the companies to provide real life display to the users in the various modern devices that they use. Computers and mobiles are two of the most important areas where this technology finds application. Samsung Galaxy and a range of the smart phones with wide touchscreen features use the LCD/LED TV display technology. Mobiles are used for a range of picture and video based works. Whether it is the playing of the multi-media files, or browsing the internet or even viewing the pictures shot from the mobile camera, these screens provide the most real-to-life display of the photos.

The LCD TV screens in mobiles are a blessing since these provide the best viewing experience of the photos, videos and along with the high resolution cameras that these smart phones come with, the viewing never got better anytime before. When the times of the CRT based TVs were around, the LCD display was limited only to monochrome screen which glowed with one light only. Mobiles have a long way since then. With better contrast ratios and higher resolution capabilities, the picture quality does not leave much to be desired.

Samsung LED TV is more costly than the CRT TV. Further, the latter gives a better view from the side angles, which is not the case with the former. For the TV, where the screens are bigger, you might need to sit straight in order to see the pictures, images or videos. But, in mobiles, due to the comparatively smaller screen size and essentially single user usage, this visual distortion does not matter much as it does in case of LCD TV.

The major benefits of the Samsung LED TVs are their excellent audio-visual delivery, slim and sleek features and the flexibility of using these as wall mounts which occupies less space. These also form part of home theatre system since wider screens can be made using the LCD/LED technology while retaining their sleekness. This was not possible in the era of CRT TVs
This has enabled the use of these TV for public viewing, besides the home or office viewing. Today, one can see these being used in the shopping malls, stadiums, crowded markets and other outdoor places.

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.
