Samsung Electronics said it would postpone the launch of a cell phone that could fold the screen. I acknowledged that there is a problem with the folded part of the screen and said that I would make a countermeasure.

First of all, I will explain to you what part of the problem there was.

Samsung Electronics announced its decision to postpone the release of Galaxy Fold through its homepage today (23th).

After investigating the product that caused the abnormality, we recognized that the folded portion of the screen was vulnerable.

The upper and lower parts of the folded part called 'hinge' are not blocked by the edge of the phone like the existing smartphone, so there is a slight gap between the screen and the shield.

Shielding is essential for OLED displays that are particularly vulnerable to oxygen and moisture, which can damage the screen.

[Byoung Kwon Ju / Professor, Dept. of Electrical and Electronic Engineering, Korea University: When oxygen and moisture enter the OLED device, isolate the electrode and organics. When the current is not supplied, the light does not come out.]

Screen damage caused by foreign substances was also confirmed. There was a foreign substance between the layer and the layer of the screen where the substrate, the OLED and the polarizing plate were overlapped.

[Dieter Vaughn / IT professional media 'The Bourgeoisie': Something was stuck between the screen and the folded part, and I do not know what it is, but that's why the screen is broken.]

Samsung Electronics said it would not mislead consumers with the idea that the plastic shield, which is part of the screen, could be removed.

With the delayed launch of the US market scheduled for the 26th, the European and domestic market launches scheduled for next month will be delayed. Product launches are expected to be delayed by at least one month.
