HD and full HD are the same. HD Ready is different. LCD and LED technology are about the same except that the backlighting of the screen is different. LCD, which uses fluorescent back lights, consumes more electrical power than LED, which uses light emitting diodes as backlighting control.
I suggest LED. I think all LEDs are HD or full HD ( 1920 by 1080 screen resolution )and not HD Ready ( 1366 by 768 screen resolution ). I have not made a comprehensive market search, though.
