“Packing four times the pixels into the new iPad’s Retina display has proven to be a challenge for Apple’s manufacturing partners, who are utilizing advanced technology like Super High Aperture pixel design and packing in double the LEDs for backlighting,” Neil Hughes reports for AppleInsider.
“Insight on the new 2,048-by-1,536-pixel screen has been offered by the NPD Group’s DisplaySearch. In a post to the firm’s official blog, Richard Shim explained that the new iPad’s Retina Display has been difficult for suppliers Samsung, Sharp and LG to manufacture,” Hughes reports. “The three companies are said to be relying on a production process known as ‘a-Si TFT,’ which has proven to be particularly difficult, as Apple’s Retina Display requirements are reportedly testing the upper limits of the technology. Shim said that the 264 pixels-per-inch crammed into the new iPad’s 9.7-inch screen is believed to be the upper limit of pixel density for a-Si TFT.”
Hughes reports, “Doubling the pixel density in the new iPad has also forced Retina Display manufacturers to double the number of LEDs for backlighting. Shim said the new screens likely include at least 72 LEDs, which could result in a significant increase in power consumption.”
