Teardown: Moto 360 Broke Ground with Round Display

The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Motorola Mobility’s Moto 360 Android smartwatch, released in September, broke new ground in that—unlike other previous smartwatches—it features a round capacitive display that looks much like those traditionally associated with wrist watches.

Prior to the Moto 360, touchscreen displays associated with smartwatches and other consumer electronics devices were almost exclusively rectangular. And while the different form factor may seem trivial, putting it into production was anything but, according to Dan Panzica, a veteran of engineering and electronics manufacturing who worked on the project as a contractor at Motorola.

“Up until that time, in our ecosystem, the displays were rectangular,” said Panzica now a senior principal analyst for outsourced manufacturing at IHS Technology. “Entire new processes needed to be created to support the circular display.”

Producing a round display involved different design rules and entire new saw process to cut the thin-film-transistor LCD panels, Panzica noted. “There is a reason no one was doing round,” he added. “The entire process was an invention.”

After some initial difficulties creating the displays, yields came up very quickly, Panzica said.

The end result was success. The Moto 360 hit stores shelves as an elegant, attractive smartwatch that many consumers gravitated to. And since the Moto 360, a number of other smartwatches with round faces have become available, including the LG G Smart Watch.

“You are seeing a lot of smartwatches with round designs out there now,” Panzica said. “Breaking that ice for the first time was very tricky.”
