4K, led and LCD are two concepts: 4K represents the clarity of the picture, while LED and LCD represent whether the backlight behind the LCD screen is the light source of LED or LCD. In contrast, LED light source is high brightness, uniform, more energy-saving, compact body and longer service life. From 2011 to 2012, most LCD TVs produced by domestic manufacturers use LED backlight; Since 2013, 4K TV has been on the market gradually, with clearer pictures, representing the latest display technology, and 4K TV must be LED backlight, so it must be better than 4K TV.

of course, the LED backlight is more advanced than ordinary cold cathode backlight.
now the LED liquid crystal TV is actually a liquid crystal TV.
but the backlight of liquid crystal panel uses LED light source, However, the performance has been improved. As a backlight, LED has five advantages over cold cathode fluorescent tube backlight: 1. Ultra wide color gamut, which can reach 105% ntse color gamut, so the color is more bright.
2. Ultra thin appearance.
the thinnest backlight can reach 1.99cm, which is more fashionable.
3. Energy saving and environmental protection.
energy consumption is 52% lower than cold cathode backlight, and there is no mercury pollution of cold cathode tube.
4 It has a long service life.
it can be used for nearly 100000 hours, and it can be used for 27 years if it is opened for 10 hours every day.
five At present, the market price of LED backlight is almost 150% of that of cold cathode backlight.
there is no choice for LED backlight itself.
the main choice for the whole machine is the technical performance parameters of LCD panel,For example, the maximum physical resolution and dynamic response time are the same as those of ordinary LCD TVs.
.
the representative brands of LCD TVs are sharp and Samsung.
they are the largest LCD panel manufacturers and suppliers in the world. Their overall development quality is stable, and all domestic products are imported screen assembly, without their own technology and low price, However, the stability of the whole machine is not as good as that of the imported brand, and the budget is rich, so the imported brand joint venture product is the first choice for this product.
