In the ever changing world of laptops, many manufactures are developing the same laptop models with different screen types. You can have 2 laptops that physically appear identical but with different screens. You can't assume you have a particular screen type because it is the only one listed on a website. With that being said:
- CCFL screens are not compatible with LED screens and there are different styles of CCFL and LED screens.
- The term LCD (Liquid Crystal Display) can refer to both CCFL and LED type screens. The LCD, simply put, is the top part of the display.
- The CCFL or LED is what lights up (or backlights) the LCD to make the display visible.
CCFL's (Cold Cathode Florescent Lamp)
CCFL screens are the older style and cost less to manufacture, out of the two. They tend to have a thicker side profile, weigh more, and produce more heat. The CCFL style also requires an inverter or inverters (know as 2-CCFL or Dual CCFL) to power the backlight or backlights (know as Dual Backlights). The backlight for the CCFLs are usually located at the bottom and top of the screen. As technology advances, the CCFL style screen will start to fade out (no pun intended).
Determining you have a CCFL style screen is not the only hurdle. You will now need to find the correct type of CCFL. The amount of backlights, the resolution, and the type of screen cable it uses can all play a factor. Because there are so many different types, it is important to know exactly which one you have.

LED's (Light Emitting Diode)
Being the newer technology LEDs, as expected, are lighter, brighter, and cooler. The efficiency of the LED screens have caused leaps with display advancements for mobile devices and laptops. Instead of using lamps to illuminate the LCD, the LED style screen uses a series of LEDs to brighten things up. The LED style screen will not use an inverter, but in some cases, they will use a converter instead.
The same as CCFLs, LED screens have many different options. The possibility of screen cable types, resolutions, and converters makes knowing your part number imperative.
