On the advantages of LEDs to the fluorescent lamps are now even know the students. Throughout the whole year LCD TVs with LED-backlit discussed everywhere - from TV to food markets. However, to enjoy the benefits of new technology until very recently, few could - too high a price of entry in the LED- club....
High-tech innovations are always a lot - or pay just me, or wait for when the product becomes popular and the prices start to fall on him. The speed of this, if I may say so, democratization depends on the complexity of the design and, of course, on the volume in which the new product will be sold to the mass market.
So, it seems that the process output LED-TVs in the masses finally starting to gain momentum. The period of elite sales clearly over, and afford new panels will soon be able not only to people who are not accustomed to deny themselves the pleasures of extremely expensive, but it is ordinary citizens, well, maybe with a slightly above average income.
Most of optimism inspires adoption rate of LED technology - at the moment it mastered though not all, but many TV manufacturers. This means that the LCD panel with LED-backlit produced in large quantities and at cost, are quite capable of competing with conventional matrices for fluorescent lamps.
In addition, developers were able to win if not completely, then smooth out the main problems is seriously light-emitting diodes - the difficulty of removing heat from a large number of densely packed matrix elements, and increasing in the course of the variation of brightness.
Designers have come up with a trick that not only helped to deal with the difficulties described, but also greatly reduced the cost of production. This, of course, talking about Edge LED, that is, the boundary illumination. Its operating principle is simple: the LEDs are not on the entire screen, but only along its perimeter. The required uniform illumination is achieved by svetoraspredelitelnoy panel made of transparent plastic, and therefore relatively inexpensive. The disadvantage of this scheme is the inability to control illumination of certain areas of the image, and hence, lower than the contrast with the classical scheme. At the same time and the benefits of Edge LED promises noticeable - not just low cost and economical power consumption, but also an opportunity to reduce the thickness of the shell just a few millimeters.
For today's test we picked up four LED- TV, three of which just uses the edge illumination. Screen size in subjects less than 40 inches, that is just right for a medium sized room. As for prices, they were not really very democratic, but in any case, far from astronomical.
* LG 37LE5500 52 990 rubles.
* Philips 40PFL9904H 179 990 rubles.
* Sharp LC-40LE700RU 54,990 rubles.
* Toshiba 40WL753R 59,990 rubles.
So, let's take a brief summary.
We examined four LED- TV, designed for installation in a relatively small living space. Accordingly, they can be used or in a modest ( by number of viewers, but not the image quality ), home theater, or as a standalone device, for example, for the living room. In both cases, the LED lights should be very useful, because it is a mediocre black depth, clearly visible in the dim artificial light, usually causes the main complaints against the LCD matrix.
And I must say, our subjects were able to substantially strengthen the belief in the future of cinema liquid crystals. It turned out that not only the full-screen, and LED lights on the boundary contrast with the stock outperforms the vast majority of systems in fluorescent lamps.
As the functionality of our heroes, too, are at the cutting edge - all TVs are able to play media from USB- carriers, and three models of the four friends with the local networks and the Internet.
Now let's move on to the individual. The all-new 40WL753R from Toshiba boasts a luxurious design and a wide range of high-tech systems, image processing and sound. Unfortunately, the effect of certain functions on pre-production samples could not be verified, which is why this model is not able to compete for awards, but the potential it has, without doubt, the high.
Specificity of Sharp LC-40LE700RU is to have a full rear LED- backlight. Parameters of most LCD panels are so high that the picture does not allow no serious hindrances. From a functional equipment is the case is less optimistic, but the inability to access the Internet more than offset by a humane, especially given the status of the brand price.
Philips 40PFL9904H from a rational point of view is not easy to describe. With an excellent technical equipment and an impressive picture, this device is intended for sophisticated and, judging by the price, well-endowed lovers of beauty. What we recommend and.

And the Grand Prix goes to LG 37LE5500. TV shows perfectly, no problems coping with a variety of multimedia files, feels confident in our etheric roads and, finally, simply elegant looks.
