DigiTimes heard Apple will be unable to mass produce the iPad 3 in the second half of this year due to poor yields of the 9.7" LCD panel with 2048 x 1536 pixel resolution:
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.
