All LED displays are technically LCDs. The key difference is their backlighting: standard LCDs use fluorescent tubes, while LED displays use light-emitting diodes. LEDs offer better contrast, deeper blacks, slimmer profiles for display, and greater energy efficiency, whereas traditional LCDs are generally more affordable.
