My question how, how can i tell that i've recieved a led screen rather than the lcd screen? Is there something i can search for on my computer? because just comparing the thickness is not convincing enough for me?
thank you!

Try this , go to yahoo and type in the model number of your monitor, it will bring up the information you need. Also lcd is better picture wise and will not leave burn in, led will

No one is making LED displays.

All the screens are LCDs. The difference is that the cheap screens use a cold cathode florescent backlight, the expensive ones use an array of LEDs.

The easiest way is going to be to take Dell at their word and measure the thickness. This would be logical as a PCB with an array of LEDs is going to be much thinner than a CCFL plus light guide.

Other than that:
Take the panel apart.

If you have two units compare the battery run time. The one with the LEDs will run longer. (swap the batteries over and run the test again to compensate for the different battery characteristics.)

If you have access to a 'scope or a sensitive frequency meter, put a loop of wire close to where the CCFL inverter card would be. If it picks up a 30 kHz to 100 kHz pulse, then you have a CCFL, if it doe snot then it is the LEDs (or you are in the wrong place, or the meter is not sensitive enough.)
