Problems at LG Displays’ production lines may have played a part in Apple’s struggle to meet demand for the iPad 2, according to a new report. Citing anonymous industry sources, DigiTimes reports that Samsung shipped a total of four million 9.7-inch IPS panels for iPads in the first quarter, outpacing the 3.2 million delivered by LG Displays. LG is said to have forcibly reduced its first quarter shipments due to a light leakage problem with panels produced at its 6G production lines, although the problem is said to have been fixed. A number of iPad 2 owners reported problems with backlight light leakage shortly after the device’s release. The report also notes that Chimei Innolux has been selected as a supplier of iPad 2 IPS display panels, but is still awaiting verification from Apple, and is expected to start shipping panels this month. A prior report indicated that Innolux had been added by Apple as a third supplier of touchscreen sensors for the iPad 2.
