Two interesting pictures emerged which allowed us to look at a project of the Chinese smartphone manufacturer Oppo. Oppo apparently working on a nearly completely borderless smartphone. A patent has been filed already to December 2014. According to the sources of the photo it will be a 5.5-inch display.
The video then shows us the smartphone in action. It probably involves an early prototype. The video is found hosted by Tencent in China.
However Oppo is not the only company working on a display without border. Also, the other Chinese producers LeTV has a similar project in the works,
