The Galaxy Fold line set to expand with 8" and 13" dual-bend display tablets

Like, for instance, not to scrape off the cover polyimide which is an integral part of the flexible display underneath, slapped on it against scratches, even though it does not completely wrap around and fuse with the panel at the edges, making it look like a screen protector of sorts.

In any case, there are the usual rumors through the grapevine that the delay in the Chinese launch may also be due to Samsung determining there are bigger problems with the flexible screen and its plastic substrate that may appear even if users don't take off the cover film, so it won't ship the Fold to stores before it investigates the potential issues thoroughly.

The polymer substrate that Samsung employs makes the Fold screen 50% thinner than that on other phones, though, and allows for some other intriguing design avenues that Samsung is exploring, reports Korean media today.

These are to be developed in a year, and include both G-type and S-type foldables with screens much larger than what we have now on the unfurled Galaxy Fold. The G-type is reportedly going to fold twice like, ahem, the letter G, and has an 8 inch diagonal when opened, while the other one folds like a squished letter S and unfurls into a whopping 13" display. This is about the diagonal of the larger Apple iPad Pro, and should bring new meaning to the phrase portable tablet. According to an official of the parts industry:

The biggest upgrade to the new Folds, compared to the original one that the company is about to release soon, is that the display bends not once but twice, and, while the G-style phone bends inwards, the S-style should be both an "innie" and an "outie." 

Samsung has numerous phone patents that depict both new styles and is now putting them in motion, it seems. Here's how these might function, according to Samsung's own patents filed with the United States Patent and Trademark Office as well as other similar bodies around the globe.
