If you want to know who makes the display in your Mac and Apple hasn't overridden the EDID information from the panel simply open up terminal and execute this string:

ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

The output will look something like this:

LP116WH4-TJA3
Color LCD

The first line is the panel's model number. Typically a quick Google search of the first few characters will give you the manufacturer's name. In this case, the LP116WH4 is made by LG Philips (hence the LP prefix). This happens to be the panel in the 11-inch Core i7 MacBook Air I just got my hands on. If you read my original review of the 2011 MBAs you'll know that both of the systems I tested there had panels by a different manufacturer:

LTH133BT01A03
LTH116AT01A04

The LT prefix on both of those part numbers implies Samsung is the OEM. The current working theory is that the LG panel in the new MacBook Air is somehow worse than the Samsung panel. Given the vast difference we saw in SSD performance between the Samsung and Toshiba drives, is it possible that Apple has allowed a similarly large gap to form between LCD vendors? Not so much:
