Look at the slogan, "Welcome to a whole new world." There is Samsung's LED technology that brings you crisp images and deep dark and bright colors. Ultra-slim Samsung LED TV".
Obviously, he would think that he used an LED screen. But in fact he just changed the backlight and did not modify the panel! It's best not to be fooled by Samsung's propaganda. Buying a TV or a panel is the most important!

LED TV is a kind of LCD, they can fool out the concept of LED, the correct name should be called LED backlight LCD TV or LED LCD TV. The name of LED TV is inherently a deception.
LED LCD TV, is to change the value of the CCFL backlight position LED backlight CCFL backlight **low but need a high-voltage inverter The backlight is either not bright or extinguished, LED can be realized through the algorithm The backlight is bright where the panel is bright and the backlight is dark where the backlight is dark. Improve contrast The improvement in image quality is not very large.
I can't save too much electricity, it's more than a dozen watts less than CCFL's, it's 300 watts, 400 watts.
Life can grow a little longer, and if you break a few tubes, you can't see that it doesn't matter.
**Super expensive, in short, it is not recommended to buy nowQuality-wise, it's just backlit and reliable.

The advantages of LED backlight ultra-long life.
LED (Light Emitting Diode) light-emitting diode (LED) was recognized as the end of fluorescent tubes, light bulbs and other lighting equipment after its birth in the 60s of the 20th century. LED lamps, also known as light-emitting diodes, have the smallest power consumption for a single LED lamp compared to other light sources.
The LED light source is composed of many grid-like semiconductors, and each "grid" has an LED semiconductor, so that the LED backlight successfully achieves the planarization of the light source. The planar light source not only has excellent brightness uniformity, but also does not require complex optical path design, so that the thickness of the LCD can be thinner, and at the same time, it has higher reliability and stability.
Secondly, in terms of luminous life, LED backlight technology surpasses CCFL and is an improvement of CCFL technology. The lifespan of ordinary CCFL backlights is basically about 30,000-40,000 hours, and the lifespan of some top CCFL backlights (WCG-CCFL) is about 60,000 hours. This longevity can last for several years, even for frequent users.
The life of the LED backlight is longer, the life of the white LED backlight at this stage has been as high as 100,000 hours, even if it is used 24 hours a day, its life can be enough for 5 years.
Energy saving and environmental protection are outstanding, and it is a truly green TV.
An important factor in the rise of LED backlighting is the RoHS directive implemented by the European Union. The Directive provides for the elimination of substances such as lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers from electronic devices sold in EU Member States from 1 July 2006. While mercury is the main ingredient in CCFL tubes and other types of fluorescent lighting, LED lamps do not use mercury at all.
In terms of power consumption,Compared with ordinary CRT TVs,Flat-panel TVs consume a lot of power,Many consumers are quite concerned about the energy consumption of TVs。 It is understood that the 12 million flat-screen TVs sold in 2008, if each TV works 4 hours a day, it will consume an additional 2.4 billion kilowatt-hours of electricity every year, which is equivalent to the total annual power generation of several large thermal power plants.
The brightness of LED can be actively adjusted with the brightness of the picture, and the effective energy saving can reach more than 30% compared with LCD TV. In this way, when representing some dark scenes, you only need to adjust the local light in the necessary backlight area (the black or darker part of the picture) to show you a high-quality image with natural contrast between light and dark.
Don't talk nonsense if there is no basis, Samsung's LED is very good, and there are many advantages.

Samsung Galaxy S III
Samsung Galaxy S III (i9300) is a high-end smartphone launched by Samsung Electronics, released in London, England in May 2012, using Android operating system, equipped with Samsung Exynos 4412 quad-core processor, the main frequency is, the body built-in 16GB storage space. The design of the machine is inspired by nature, with a rounded and smooth body without clear lines, and the colors are available in pebble blue and marble white. It is equipped with an inch HD Super AMOLED capacitive screen with a resolution of 1280 720 pixels, an 8-megapixel camera on the rear with LED flash, and a 1.9-million-pixel camera on the front.
This mobile phone not only has a powerful configuration, but its newly designed human-computer interaction function also makes the mobile phone more convenient to operate.
I'm a fan,I bought SamsungQLEDTV to watch the game,I feel that the biggest advantage of this TV is that the color is very close to real,Accurate brightness contrast,More details in the picture,The sound effect is superb。 For example, the jersey I wore finally had no color difference, the stadium I saw was finally the same green, and even the cheering was so real......
Nowadays, many TV stations have such tips
I'm a professional TV,The color of this TV image is very good,The clarity is very good in similar products,The sound quality can only be said to be average,After all, the speaker power of the flat-panel TV is limited,And the design is not conducive to the best effect,If you want to have good sound quality, you still have to buy audio。
To tell you the truth, this one really doesn't.
U608 is beautiful, ultra-thin, but standby is not good, and it is only more than 1 day if it is used normally. >>>More
