3 Questions and Answers to CCFL

How flatscreen Computer screens are Assembled

Tvs all flat-screen pc monitors, tablet PCs, and laptop displays use twisted-nematic/thin-film transistor, active matrix, liquid-crystal displays. The term "liquid-crystal show" is where the acronym LCD comes from. Both LED and liquid crystal display monitors use this type of technology.

Why is LCD and LED screens distinct is the type of backlight used. All flat panel shows have a backlight, normally at the foot of the unit, which reflects light throughout the viewing area to illuminate the display for the consumer. There is a CCFL light a type of fluorescent tube, that has been the technology embraced to provide the backlighting in early -design flat screen displays. Often, when you see a screen advertised today as a "LCD monitor," it is using the older CCFL back-lighting technology.

Why Manufacturers Changed to LED Backlights

The newer LED back lighting technology got its beginning in 2007, when Apple, Inc. declared that it would begin transitioning a way from utilizing CCFL tubes for back-lighting in its screens, and rather use LED lights. The phrase "LED" means "light-emitting diode." There were several grounds for switching to LEDs for backlighting:

Helping the environment. CCFL tubes, like all fluorescent tubes, comprise mercury vapor which is energized to make the lighting effect. The requirement for mercury is removed in LED backlit screens.

Energy Savings. LED backlights demand not significantly more electrical power- about 40% to 50% less than CCFL backlights need. They also create less waste heat.

Simplification of Design. Switching to LED backlighting additionally enabled simplification of the layout of a computer screen. Screens with LED backlighting weigh less than CCFL backlit computer screens, because of elimination of the fluorescent tube and its associated ballast and are more slender.
Using LED back lighting Empowered Functionality Gains

Contrast Ratio is the ratio of the light of the most vivid color (white) as compared to the darkest colour (black) that there is a screen effective at generating. LED backlighting could be dimmed if not shutdown to supply pure- . This provides for Mo-Re realism in dark scenes; for example in night-photographs in movies or in dark rooms while gaming. The Dynamic Contrast Ratio of a CCFL can be 30,000,000:1, while it backlight might be 100,000:1. With high definition LED screens, the darker black amounts enhance brightness for a much more brilliant picture at all color degrees.

LED lighting has taken the world in everything from light bulbs; by storm, in backlighting in flat-panel shows, and now to flashlights. Perhaps your next screen will probably be among the LED computer screens that are new!
