LED is light emitting diode LightEmittingDiode English abbreviation.
LCD and led the difference between LED applications can be divided into two categories: First, LED single tube applications, including backlight LED, infrared LED, etc ; the other is the LED display, at present, China's LED base material manufacturing and international still exist A certain gap, but the LED display, the Chinese design and production technology level and international synchronization.
The LED display is a display device consisting of light emitting diodes. It uses low-voltage scanning drive, with: less power consumption, long life, low cost, high brightness, less failure, large viewing angle, visual distance and so on.
LED display and LCD display compared to LED in the brightness, power consumption, viewing angle and refresh rate, etc., are more advantages. LED and LCD power consumption ratio of about 10: 1, and a higher refresh rate makes the LED in the video has better performance, can provide a wide viewing angle of 160 °, you can display a variety of text, digital, color images And animation information, you can also play TV, VCD, DVD and other color video signals, multiple displays can also be networked. Organic LED display a single element of the reaction speed is 1000 times the LCD screen, in the light can also take care of the wrong, and to adapt to minus 40 degrees low temperature. The use of LED technology, can produce thinner than LCD, brighter, more clear display, with a wide range of applications.
Simply put, LCD and LED are two different display technology, LCD is composed of liquid crystal display, and LED is composed of light-emitting diode display. LED display and LCD display compared to LED in the brightness, power consumption, viewing angle and refresh rate, etc., are more advantages.
LCD is the full name of the LCD screen: it includes TFT, UFB, TFD, STN and other types of liquid crystal display.
Notebook LCD screen commonly used is TFT. TFT screen is a thin film transistor, the English full name (ThinFilmTransistor), is the active matrix type LCD display, in its back set a special light pipe, you can take the initiative to control the various pixels on the screen, which is the so-called active matrix TFT origin, This can greatly improve the time, about 80 milliseconds, while the STN of 200 milliseconds! Also improved the STN flicker (water ripple) blurred phenomenon, effectively improve the ability to play the dynamic picture, compared with the STN, TFT Have excellent color saturation, restore ability and higher contrast, the sun is still very clear, but the disadvantage is more power, and the cost is higher.
OLED: OrganicLightEmittingDisplay, that is, organic light-emitting display, mobile phone LCD on the new rise of the species, known as the "dream display." OLED display technology and the traditional LCD display different, no backlight, using a very thin organic coating and glass substrate, when there is current through, these organic materials will light. And OLED display screen can be made lighter and thinner, the viewing angle is greater, and can save significant energy. However, although the future of better OLED technology will replace TFT and other LCD, but the organic light-emitting display technology there are still short life, large screen and other defects.http://www.gentwin.com/
