What is LED
LED is the acronym for Light Emitting Diode LightEmittingDiode , LED applications can be divided into two categories : First, single-tube LED applications, including backlight LED, infrared LED, etc. ; another is the LED display.
The LCD is short for liquid crystal display . It includes a TFT, UFB, TFD, STN and other types of liquid crystal display.
Technically, from the display , LCD is a liquid crystal display , the LED light-emitting diodes is set by the display. LED digital display, each pixel element is a light emitting diode , If the color , usually red light emitting diodes. If the color is generally composed of three primary colors of a small diode large diode. These diodes matrix composed by the real-time digital control display text or images, relatively low cost , large area consisting of imaging . General stations, squares and other public places subtitles cards, open-air digital TV wall are LED .
While the lcd module pixel units are integrated in the same LCD panels which separated out a small box . Through the digital control these tiny squares for imaging , the performance effect is more delicate. LED Advantages: good color , long life, environmental protection is backlighting applications, the color is good , long life, environmental protection is the LED advantage lies. As we all know , LCD itself does not glow, it relies on the backlight will light through the display panel , displaying graphic images. Therefore , backlight LCD TV technology directly affects the image quality .
Conventional liquid crystal display usually CCFL backlight , the cold cathode fluorescent lamps. CCFL has a lot of very nice features, including excellent white light source , low cost, high efficiency , good stability , easy operation . Has been widely used in notebook computers, desktop computers and televisions .
But the CCFL is considered enough green , mercury ; color performance is not only achieve the NTSC 70 % ~ 80% ; for large- size TV screen , CCFL tube voltage and extended height of processing is difficult.
In contrast , LED light-emitting diode as a light source that can provide red , green, blue , green , orange, amber , white and other colors, broader color gamut that can reach 105% of the NTSC color gamut , which for OLED Module TVs color has provided a guarantee .
In addition, LED lifetime is very long service life of up to 100,000 hours , if the boot 5 hours per day basis, a station with LED backlighting LCD TV can be used for nearly 55 years . In addition, it is not mercury, better environmental performance . LED urgent problems facing : cost, technology , light efficiency
LED (Light Emitting Diode) light-emitting diodes, born in the 1960s after being identified as fluorescent tubes , light bulbs and other lighting equipment Terminator . LED light emitting diode , also known as , compared to other light sources , a single LED light dissipation is minimal. From blue to red , LED lights have a variety of colors , there is a special color is white. Our custom as " cool white " and " warm white " two.
LED light source is composed of many semiconductor grid-like composition , each " grid" has an LED semiconductor , LED backlight on the successful implementation of such a light source plane . Planar light source not only excellent brightness uniformity, do not require sophisticated optical design , so that the thickness of the LCD can be thinner , but also has a higher reliability and stability.
Secondly, in terms luminescence lifetime , LED backlight technology is beyond CCFL, CCFL technology is improved. Common basic life CCFL backlight in 30,000 -4 ten thousand hours or so, some of the top CCFL backlight (WCG-CCFL) life of about 60,000 hours. Such frequent use of life even for users, but also to maintain a good few years . The LED backlight life even longer , at this stage has a white LED backlight lifespan up to 100,000 hours, even 24 hours continuous use , its life may be sufficient for five years.
