Amazon.com plans to unveil a smartphone with a 3D display in June and start selling it from September, according to the Wall Street Journal on Friday.
Last October, rumors surfaced that Amazon was working on new smartphones with the assistance of Taiwan's HTC.
"The retailer has been demonstrating versions of the handset to developers in San Francisco and its hometown Seattle in recent weeks," the daily reported.
The phone enables users to watch 3D images without special glasses using "retina-tracking technology embedded in four front-facing cameras, or sensors, to make some images appear to be 3-D, similar to a hologram," the WSJ wrote.
A 3D phone with similar technology was released in Korea, but due to the inferior quality of its 3D images and the weight of the gadget, sales failed to measure up to the hype.
