Apple Insider posted a story that Apple's newly released Thunderbolt Display sports an LG display with the same model number found in the 27-inch iMac released in 2009, a teardown of the screen has found.

The new display, powered by Apple and Intel's Thunderbolt technology, was disassembled this week by iFixit. They found that the LG display is model number "LM270WQ1," matching the previous iMac as well as the screen found in Dell's competing UltraSharp U2711 27-inch monitor.

However, Apple's display uses LED backlights for better picture quality and lower power consumption, as opposed to the cold-cathode fluorescent lamps (CCFLs) found on Dell's screen. In addition, the Dell display is matte, while Apple's is glossy.
