You are purchasing a BRAND NEW 15.6" WXGA HD Glossy LED LCD.  This LCD is compatible with many laptop models as well as many LCD screens.  This 15.6" LCD is LED and does NOT use an inverter (Some Sony PCG-71312L models use a different screen so you'll want to verify which one you need).  This screen has the LED connector towards BOTTOM-LEFT (If facing the back of the screen).
