US-based tablet PC players Apple has recently canceled its iPad 3 supply schedule for the second half of 2011, forcing other tablet PC brand vendors that are set to launch same-level product to compete, to follow suit and delay their launch; however, supply of the iPad 2 in the second half will still be maintained at 28-30 million units, according to sources from the upstream supply chain.
Apple was originally set to launch its iPad 3 in the second half of 2011 with a supply volume of 1.5-2 million units in the third quarter and 5-6 million in the fourth quarter, but Apple's supply chain partners have recently discovered that the related figures have all already been deleted, the sources pointed out.
The sources believe that the yield rate of the 9.7-inch panel that feature resolution of 2,048 by 1,536 may be the major reason of the supply delay since such panels are mainly supplied by Japan-based Sharp with a high price and Apple's other supply partners Samsung Electronics and LG Display are both unable to reach a good yield. Since Apple is unable to control a certain level of supply volume, the iPad 3 is unlikely to be mass produced as scheduled, the sources added.
Sources from panel players also pointed out that the 9.7-inch panel with high resolution requires a much larger backlight source and a single edge light bar is hardly able to reach satisfaction levels. Due to iPad 3's requirements over the physical thinness, rich color support and toughness will all conflict with the panel's technology restrictions; therefore, this could cause a delay in the launch.
In June, LG Display supplied three million panels for the iPad 2 with Samsung supplying 1-1.5 million units and Chimei Innolux (CMI) 10,000-20,000 units. In July, LG's supply volume dropped to 2.8 million units with Samsung maintaining its same levels, and CMI's volume increased to 450,000-500,000 units.
