LCD is the highest power consumption in notebook components

By Toshiba LibrettoU100, for example, 7.2 inch LCD screen, wholesale electronic stores with 32 independent control body to the LED backlight system to achieve, you can clearly and clearly display images and text, power consumption is only 1.3W, while the same size need CCFT LCD cold cathode fluorescent tubes in power for more than 2.5W. LED displays and LCD monitors, higher refresh rate makes the LED in the video has a better performance - LED display of a single element of the reaction rate is 1000 times the LCD screen in bright light you can not stop watching error, and adapt to the low temperature of minus 40 ℃. In addition to low power consumption, to environmental protection, LED there is a big advantage, it is up to 100,000 hours life, even if used continuously for 10 hours a day, you can spend 27 consecutive years.

However, LED, there are some more serious birth defects, wholesale electronic stores one of the most troubled of the industry should be LED luminous efficiency. The LED backlight device as to the type of mostly white, wholesale electronic stores and white LED light at the beginning of the device is not efficient, resulting in generally low screen brightness. For example, in the current LED technology, no matter who the manufacturer of the screen, LED brightness components are different. Currently CCFT Cold Cathode Fluorescent Lamp luminous efficiency can reach 50 ~ 100lm / W (lumens / watt), while the white LED devices in the start of light-emitting efficiency is only 20lm / W or less, this problem has led to the color shift, inconsistent poor color purity and quality of the true "white", which is destined not for the beginning of the LED as the backlight LCD display. 

To eliminate this problem, LED chip manufacturers to "partition" or wholesale electronic stores broken down into a similar color and brightness of the block. This deal will certainly help, but there is still insufficient brightness and color shift still exist. Though the company has developed a color correction circuit can correct this problem to some extent, but the uniformity of the problem still exists. Fortunately, technological advances in the field very quickly, white LED luminous efficiency at an annual rate of increase 60 upgrade, so far, the device luminous efficiency white LED breakthrough 50lm / W, begin to reach a practical level.
