LED LCD set off a wave of industrial upgrading

If the same picture hanging on the wall of the ultra-thin TV attracted the attention of the participants, more colorful, higher contrast the excellent quality and magnificent appearance design...... LED products in the domestic market began large-scale appearance. Samsung has just launched 3 series a total of 9 new LED TV, LED TV has become the first domestic mass market TV manufacturers, at the same time, SONY, SHARP and other international manufacturers have also targeted the LED TV, domestic manufacturers Hisense, Konka launched their new LED TV, LED technology has become flat the television industry a hot topic recently.

Back light source -- the fundamental difference between LED and LCD

LCD lcd. LED that is Light Diode Emitting, we often say that the light-emitting diode. The difference between the traditional LCD TV and today's LED TV is on the backlight. Chinese CVIA Deputy Secretary General Hao Yabin said, LED TV uses LEDs as the backlight source, rather than using the lamp as a backlight, from technology to save space.

After years of development, LED has been applied in a number of areas, including mobile phone backlight, computer display, etc., but in the field of television, LED technology is truly a new topic. Until 2007, Samsung Corp took the lead in the introduction of the world's first commercial use of LED technology 70 inch TV, officially opened the prelude to the LED TV market.

Using LED as the backlight of LCD TV, the main purpose is to improve the image quality, especially color saturation, the wide color gamut can be achieved even more than Adobe RGB and NTSC color standard, can achieve NTSC color gamut coverage of more than 105%.

LED is lighter, thinner and more environmentally friendly

Chief China Samsung Group Vice President Gao Yang Qin told reporters, TV manufacturers using LED as the light source of the reason is that it has higher light efficiency than the existing fluorescent lamps, and bring more high-quality picture has many advantages to bring added value to the tv.

Compared with LCD technology, LED has obvious advantages in many aspects: the first is the high brightness; second is a wider color gamut, more bright colors; the third is the white balance of backlight can be adjusted, while ensuring the overall contrast. When the user's video source switch between the computer and the DVD machine, you can easily adjust the white balance between 9600K and 6500K, and will not sacrifice the brightness and contrast; fourth is a large range of brightness adjustment. Therefore, both in the bright and dark room, the user is very easy to display the brightness of the device to adjust to the most pleasing state; fifth is the use of a wide range of temperature, low voltage, impact resistance. Because the solid state light emitting device with LED backlight, not fragile parts, the ability to adapt to the environment is very strong.

Low electromagnetic radiation is also the main advantage of LED, because of its light source does not produce any ray, no mercury and other toxic substances, can be described as a green light source. At the same time, because the light emitting element volume LED is very small, it has a significant contribution to the ultra-thin LCD TV, LCD manufacturers have launched several high-end ultra-thin LED backlight products, the effect is quite shocking, but also one of the trend of the future.

Technology patents become a spectacle

It is understood that this year, including PHILPS, LG, Toshiba, Hitachi, Changhong and other brands have launched LED backlight LCD TV products, LED backlight technology has become the technology of LCD TV and a trend of screen full HD, the ultra-thin, driving speed. But because the technology is still in the immature stage, higher product costs, resulting in the high price of LED TV market, compared with LCD TV, the price is more than 3 times, although the product has a good advantage, but consumers elusive, also caused LED TV but shaorenwenjin Wumart embarrassment situation.

Therefore, the international giants have been in full swing in technology research and development. Gao Yangqin, chief vice president of Greater China, Samsung Group, for LED, Samsung Electronics Applications for more than 3000 patents, has become the world's most innovative TV manufacturers LED TV technology companies. According to reports, Samsung Electronics has developed a thickness of only 20mm of the goal of LED TV, which is equivalent to 1/4 of the thickness of the previous product.
