The terms CCFL and LED are the two different types of screens that laptops can use. This is important information to know because one type will not work on a laptop that requires the other. For those needed CCFL model, there are two types of backlights 1-CCFL and 2-CCFL.
CCFL (Cold Cathode Fluorescent Light - High Intensity Discharge Lamps) was mostly used in older laptops. It comes in two types 1-CCFL or 2-CCFL and also required an inverter to power the lamps. 1-CCFL or “single backlight” contains one bulb to light it up and a pair of wires at the bottom. It has one white inverter connector that is used for plugging into inverter board. 2-CCFL or "dual backlight" contains 2 bulbs, has 2 inverter pair cables as well as 2 inverter connectors.
LED screens are the most common, especially in new laptops and they are available in several different types in terms of resolution, data/video connectors and the type of fittings needed depending on the laptop you own. LED’s are becoming more famous because of higher efficiency in terms of size, resolution, power consumption, heat generation etc.
If you have never purchased laptop screen before, then you’ll need to know a little information about your existing faulty screen before you buy replacement. The most important information is the manufacturer’s code and the screen size. Fortunately, the information for both can be found in one place, on the back side of the screen itself.
If you have removed your faulty screen from laptop, simply turn it around and look for the manufacturer’s code which is written on the back. This is the information you need to search for in order to get correct replacement screen. For example let’s say the code you find on the back of your laptop screen is LTN156AT01.
This translates into having a Samsung 15.6 inch screen. The “LTN” is the code for Samsung and the “156” is the code for the screen size of 15.6 inches. You’ll often see this code next to or above the UPS bar code for the screen.
