LED into the future trend

Hisense TLM42T08GP backlight technology used by the industry is generally optimistic about the LCD TV core technology LED. LED light emitting diode known to the public, is a kind of semiconductor light emitting element, applying voltage to the semiconductor chip at both ends, carriers in semiconductor composite induced photon emission so that the light can emit red, yellow, blue, green, orange, purple, white light.

LCD TV screen is not illuminated, voltage is applied after the liquid crystal molecules by changing the direction which affects the transmission of light to achieve the purpose of displaying images, therefore, backlight plays an important role on the screen color gamut. Currently widely used in the industry CCFL (cold cathode backlight) backlight can only achieve about 70% of the NTSC color gamut value. However, the use of LED backlight LCD screen, color gamut values can generally reach more than NTSC 110% color gamut value, so that more colorful, more vivid imaging, closer to the real color.

In addition, LED as backlight has more advantages. Using LED backlight, energy consumption than ordinary TV, the service life is much longer. In addition, LED backlight production does not use lead, mercury and other heavy metals, to avoid the destruction of the home environment and ecological environment. Dynamic contrast to 40000:1, the bright field, dark layered, richer picture.

As a major trend in the development of the industry, Hisense actively involved in LED backlight R & D. Hisense large size LED backlight module project has been the country's 863 major projects and electronic information industry development fund. After 2 years of efforts, the national brand LED backlight LCD TV was finally successfully listed in Hisense.
