iPad 2 Still Suffers from Yellow and White Light Leakage Issues (Spots)
Apple iPads last year also had an issue where the left side of the screen was slightly brighter than the right side.
Almost all LED and LCD screens have some white light leakage issues, but I have to say that the iPads exhibit an abnormal amount (plus its yellow in some areas of the screen). The flashlighting or light leakage can be seen when looking at dark backgrounds or black user interface elements under lower lighting conditions.
