Samsung Electronics unveiled the display of its foldable smartphone at the Samsung Developer Conference (SDC) held at the Moscone Center in San Francisco on Nov. 7 (local time).

Samsung Electronics has unveiled the display and user interface (UI) of its foldable smartphone that will be released in 2019.

Samsung Electronics held the fifth Samsung Developer Conference (SDC) under the theme "Where Now Meets Next" at the Moscone Center in San Francisco on Nov. 7 (local time).

More than 5,000 people attended the conference, including developers and service partners from around the world, and showed high interest in Samsung Electronics' latest technologies, including its foldable phone and AI platform Bixby.

In particular, Samsung unveiled the display of its much-anticipated foldable smartphone that will be released next year, the 10th anniversary of the Galaxy smartphone.

The display, dubbed “Infinity Flex Display,” is an in-folding display that measures 7.3 inches when unfolded and 4.6 inches when folded.

What Samsung unveiled at the SDC was not a prototype of a foldable smartphone but its display. It showed only an introduction video for the smartphone without demonstrating its operation, saying it will provide a strong multi-tasking experience.

But the company disclosed detailed specifications of Infinity Flex Display during a session titled “Is your app ready for foldable phones?”

Park Ji-sun, senior engineer at Samsung Electronics' Wireless Business Department, said the cover display has a screen ratio of 21:9 while that of the main display is 4.2 to 3. Both displays have a resolution of 420 dpi. Other specifications such as batteries and release dates were not made public.

"The cover display is somewhat smaller than the displays of ordinary smartphones but all functions of apps available on the main display are available," Park said.

Samsung Electronics explained that main display is optimized for multi-tasking because it supports multi-window functions. Users can either use only one app on the main display screen or two or three apps at the same time. For example, you can view YouTube in full screen on the left and divide the screen on the right to use both text messages and Internet browsers at the same time.

Samsung Electronics and Google introduced guidelines for app development so that developers can participate in early development of foldable applications. Emulators (devices designed to copy or run the same device characteristics) will be released within the fourth quarter.
