Apple (AAPL -2.19%) already knows that it's going to have a hard time keeping up with demand this quarter for the iPad Mini with Retina display. Reports have been circulating for months about expected supply constraints, and Apple implicitly confirmed them by saying the device would only be available "later in November." Investors now have another possible nugget of truth, as DIGITIMES is reporting that Sharp is the culprit, which is expected to be supplying 40% of Apple's 7.9-inch Retina panels. LG Display should be responsible for the remaining 60%. LG Display and Sharp use different manufacturing procedures, and Sharp's production remains plagued by low yields. 

As with all rumors, investors should consider this report with a grain of salt. In the broader picture of what investors have been hearing about supply constraints for Apple's new small-sized tablet, the rumors have some legs. That could present some challenges this quarter, as the iPad Mini with Retina display would be bound to be a popular stocking-stuffer -- if consumers can get their hands on them.
