Samsung Display is working on solving the front camera transparency problem. As per the new report, Samsung has set a goal to apply a transparent PI substrate to its foldable phone by 2024 (Possible Galaxy Z Fold 6).
The Elec report suggests if the yellow PI substrate is replaced with a transparent PI substrate, the light transmittance increases, making it possible to take clear photos with an under-display camera.
In the race, LG Display is also solving this issue by developing a transparent PI substrate with the goal of supplying it to Apple.
Samsung 2024 Fold phone will get the transparent PI substrate
The flexible organic light emitting diode (OLED) applied to foldable phones currently in mass production uses a yellow PI substrate, and the goal is to replace it with a transparent PI substrate.
Samsung Display has reportedly decreased the pixel density of the UPC area to 187 PPI, which is half of the 374 PPI (Pixels Per Inch) of the rest of the display area, to compensate for this shortcoming in the UPC first applied to Samsung Electronics’ Galaxy Z Fold 3 last year.

If everything goes well then Samsung will become the first company to apply it to Samsung Electronics’ foldable phone OLED, and then aim to apply it to Apple’s iPhone OLED. According to the roadmap, LG Display plans to increase the UPC light transmittance to 20% by 2023 and 40% after 2024.
