Laptop screens come in two main types. LED backlit and LCD CCFL. When ordering please make sure that you order the correct screen. Check the part number. If we do not have your part number listed then please contact us before purchasing as we may be able to match up a compatible screen as many screens fit many laptops.
LED screens are the latest type and can be identified by their total lack of any visible wiring from the top or bottom whilst LCD CCFL screens have a noticeable wire from the bottom which powers the light tube inside. These have a plug which connects to an inverter somewhere at the bottom of the laptop screen housing.
These are typical LCD CCFL and LED screens as seen from the back.
