LCD and LED

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have now shifted their focus on making the more practical, slimmer, LCD/LED TV sets which are fast replacing the outdated CRT sets.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.

Blu Ray Disks And Player

Change of and advancement in the technology of consumer electronics has never stopped or reached saturation. Continued research by the scientists has led to the development of newer instruments or devices with loaded features, improved functionality and better user experiences. This has also been the case with the optical storage devices like the CDs/DVDs. When one were thinking that the high definition DVDs are one of the greatest feats of the modern times and that these are going to stay here for sometime to come, the Blu-Ray disks came to the forefront as further improvements over the previous HD DVDs.

Blu-ray disks are a more compact version of the DVDs. These are able to store much more data and are more scalable as well. These are called so because the blue laser is used to read the data. This allows the data to be stored on this optical storage device in a more compact way. The blu-ray players are the devices which are used to read the video formats on these disks. The choice or selection of blu ray player would depend on whether you have a compatible HD TV as well or not. While having a HDTV is not a necessary condition for using these, there is definitely better quality output that can be had using the HDTV. Also, you will be requiring the HDMI connecting cables between the player and the TV. Most of the movies currently are being recorded on these modern optical storage devices, in the 16:9 aspect ratio, which is also the standard aspect ratio for the HD TV screens. Therefore, if you are viewing these on standard definition TV, it may not appear in full screen mode.


Some of the main features of these devices which can be derived by reading the blu ray reviews are given below:

1.High storage capacity: These can store up to 50 GB of data which is almost five times the storage capacity of the SD DVDs.

2.High definition support: It provides support for the full 1920*1080 pixel resolution levels, the highest for best quality video production.

3.Surround sound: This brings out the sounds in full clarity. Uncompressed sounds are delivered.

4.Faster data transfer rate: There is a difference of almost four times in the data transfer rate between it and the SD DVD.

5.Compatibility with the SD DVDs as well as CDs is another notable feature.

6.Resistance to scratches. This is another improvement over the traditional optical storage media. Earlier, there were problems of scratches on there devices since the data was stored very close to the surface. With coating technology these problems have been reduced considerably.

There is often a need for the blu ray player to play the MP3 CDs. This is distinctly possible with the recent blu ray player which come with quality converters. It is important to note that the blu ray CDs can be played only on blu ray players, not on DVD players. The MP3 players are available in different formats and can be used for playing both the audio and video files.
