The 1.4mm radius enabled the South Korean company to create a smaller folded gap compared to the original model, which besides stopping dirt from slipping into the display, also makes for a neater design.
Samsung claimed that French firm Bureau Veritas certified the display for 200,000 folds.
The smartphone also has the lowest blue-light emission is the lowest ever, with 6.5 percent.
And the 7.6-inch, 2,208 x 1,768 display is the third bendable model phone by Samsung.
The firm claimed that they've had over 50,000 pre-orders for the $2,000 smartphone.
Earlier this month, it was reported that a whopping 230,000 people in Korea signed up to enter a draw to buy the $3,299 Galaxy Z Fold 2 Thom Browne edition.
The limited run of the device which has been designed in partnership with the fashion brand saw people flock in the thousands to be in with the chance of owning the smartphone.
Samsung only has 5,000 units available, with South Korea only getting 1,000 units.
Those who wanted to pre-order the phone had to sign up by September 8, and if they make the 1,000, they'll get their hands on the in-demand device on September 25.
The Thom Browne Edition has already sold out in Thailand.
