According to NPD DisplaySearch, the iPad 5 is expected to feature a redesigned LED backlight apparatus which may get it closer to the iPad 2 in thickness and weight. (via CNET). Analyst Paul Semenza suggests that a thinner, lighter LED design will be achieved partly by making the display more efficient and partly by using more efficient LEDs.
“It’s likely that part of the thinner/lighter design will be reducing the size of the LED backlight, partly by making the display more efficient and partly by using more efficient LEDs,” said Semenza.
NPD DisplaySearch also feels that Apple could be likely to change parts of the way the iPad 5 senses a user’s touch saying, “The other significant change that we feel is likely is a shift to a film-based touch sensor.”
The 3rd and 4th generation iPads gained significant weight and thickness as compared to the iPad 2 due to technologies supporting the Retina display.
Speculation of IGZO displays, which were first rumored to be headed to Apple’s iPhone 6, have multiplied in recent months and now also point to the technology’s inclusion in the iPad 5. IGZO displays have lower power consumption and more accurate touch support according to Sharp’s presentation at CES 2013. Sharp gave Gotta Be Mobile got a demonstration of the screen technology which you’ll find below.
IGZO, which stands for Indium Gallium Zinc Oxide, is a type of material created by Sharp and partner Semiconductor Energy Labs that acts as a semiconductor for electrical current. Because it can be used in extremely thin-film transistors or touch layers it’s able to offer manufacturers a way to create displays for phones, televisions, and in Apple’s case, an iPad 5 with even higher screen resolutions and more power efficiency. Typically, displays are one of the biggest draws on a mobile device’s battery.
The new iPad 5 is expected to arrive sometime in the third quarter.
