Most hd TV manufacturers now offer a variety of LED HD TVs.
Led hd TV is based on the same basic technology as LCD hd TV, but on the back
The lighting used to create pictures on the display is different.
LCD HDTV usually uses an array or tube located behind the display to produce light that allows the HDTV to display pictures.
The disadvantage of this form of back is
Lighting is that some areas of the picture look brighter than others.
It is also more difficult to create a good black grade.
Led hd TVs use many smaller LED lights to make pictures.
This allows for more dynamic adjustments to the lighting as there are many LED lights that can adjust their level to create the best picture.
This has increased the level of black a lot.
In addition, LED lights often require less physical space, making HD TVs with this technology thinner.
Led hd TVs are significantly better than traditional LCD TVs, but the new technology still has a price advantage.
Which led hd TV is worth buying? Sony Bravia KDL-
55XBR8Sony has always been a leader in high-definition TV technology, KDL-
55XBR8 is the flagship product of Sony LED technology.
So it\'s not surprising that this is a great hd TV.
Its biggest selling point is that it can be directly attributed to the selling point of LED technology-the black level.
Sony Bravia KDL-
The 55XBR8 is capable of approaching the black level of most plasma devices and most viewers will not be able to tell any difference.
However, the XBR8 is also bright enough to be viewed in a sunny room.
The XBR8 also features an excellent image processor with a large number of options, which makes the XBR8 friendly to a variety of resolutions and formats.
In fact, the XBR8 has almost no negative impact when playing any type of video.
Great color, great action and great viewing angle.
But, of course, there is a problem. The KDL-
The retail price of 55XBR8 is about $4500.
In a world where you can buy very good LCD TVs and plasma HD TVs for $1500 or less, this is a huge asset.
Unfortunately, this price will disqualify it from the center stage in many living rooms, but if you have this cash, KDL-
55XBR8 is undoubtedly the best led hd TV at the moment.
Although the LG LH90 series is not often considered the top of hd TV games, LG has made great progress in becoming a leader in the past year.
The LH90 series is another example of this effort.
With 42 to 55 inch sizes, The LH90 series is one of LG\'s top HD TVs.
It takes full advantage of LED technology and therefore provides excellent black level performance.
Thanks to its matte screen, this performance is easy to see even in rooms where glare is usually generated.
Color accuracy is also in stock
Although the perspective of the LH90 seems limited.
This may make it difficult to use in a large living room.
In addition to LED technology, The LH90 is also one of the first HD TVs to use the 240Hz technology.
This should make hd TV better in high definition
But in fact, the difference is hard to notice.
This makes sense because there is a limit to how much movement the human eye can record.
The LH90 also includes a wealth of connectivity, including 4 HDMI inputs, which is handy.
The price is also very convenient as the 47 inch LH90 sells for about $1800.
This makes the LG LH90 series great value for money.
Samsung\'s UNB8000 series does not have manufacturers to promote LED technology like Samsung.
UNB8000 series hd TV is one of Samsung\'s many led hd TV series.
This picture is a bit disappointing.
Samsung\'s black level is not as good as LG LH90, and the contrast is not as good in dark scenes.
Samsung\'s unb8000 perspective problem is also a bit bad.
However, Samsung\'s UNB8000 pictures are still better than almost all LCD or LED HD TVs, and the UNB8000 series makes up for picture quality by offering some great features.
The UNB8000 hd TV supports Yahoo widgets and web streaming.
They are also very energy efficient.
Then the size-the UNB8000 is only 1.
2 inch thick, is one of the thinnest HD TVs ever.
The price of Samsung un46 b8000 is about $2200, and the LG LH90 provides better value.
However, Samsung\'s better feature set will appeal to the hearts of those who don\'t buy hd TV based solely on image quality.
