Different supply chain checks mostly point to Apple’s fifth-generation iPad being lighter and thinner over its predecessor, the iPad 4. According to one display expert, Apple will achieve the thinner appearance in a light device thanks to a few advancements in the iPad’s display department. For starters, in reducing the size of the LED backlight and improving its efficiency, Apple engineers will be able to reduce the overall weight of the device. The company may also use a new kind of touch sensor, he speculated Friday…
CNET quotes NPD DisplaySearch analyst Paul Semenza:
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. The other significant change that we feel is likely is a shift to a film-based touch sensor.
The iPad mini, which is 7.2mm thick, incorporates a DITO film touch panel sensor. In addition to a thinner and lighter display assembly, the next full-size iPad is also thought to adopt the iPad mini’s narrow side bezels.
DisplaySearch knows a thing or two about display technologies and they correctly called for the in-cell display tech on the iPhone 5 ahead of its release. On the other hand, the company incorrectly predicted the iPad 4 would be thinner than the third-generation model.
It wasn’t immediately clear what some concrete leads or pure speculation led Semenza to claim knowledge of Apple’s plans. He also couldn’t tell whether or not there will be “a big change” to the iPad’s 9.7-inch screen, such as using IGZO (indium gallium zinc oxide)panels by Sharp.

The rumor-mills speculated Apple could adopt IGZO for next-gen iOS devices, but it is believed that ongoing issues with manufacturing yields and Sharp’s financial woes led Apple to stick with IPC LCD technology used on current iPads.
Currently, Sharp is only able to produce IGZO panels for smaller devices sold in the Japanese market.
The company did hire a former LG Display OLED expert, indicating it is actively researching emerging technologies and constantly evaluating its options.
