The Samsung Galaxy Z Fold 2 may be brand new but we already know one area where its successor the Z Fold 3 will improve: its selfie camera. According to reports, Samsung will eventually dig into the punch-hole camera design and place the front camera at the bottom of the display, showing the Z Fold 3 company’s first all-screen display.
According to Korean site The Elek (found via Android Authority), Samsung originally hoped to implement it on the Samsung Galaxy S21, but had to abandon their plan “due to low production yields”.
We’ve known since May 2019 that Samsung had an all-screen front design and an integrated cam position at No. 3 on our Galaxy S30 / S21 wish list for new features. Unfortunately, we have to live with the conventional pop-up design, which exposes the camera to potential damage and closes some screen space.
The Galaxy S21 is expected to launch in February 2021, and the Z-Fold 3 will probably not end until the end of 2021 as a more niche product than the flagship S21, and with more time to develop the technology, the Z feature will be tested. Fold 3 seems like a logical candidate to do.
In addition to Samsung, Xiaomi also has plans for 2021 under-display selfie cameras for third-generation phones, such as ZTE’s Exxon 20 5G smartphone.
How technology will work
Samsung smartphones already have on-screen fingerprint scanners, but implementing a screen camera presents more challenges.
According to The Elek, Samsung has tried several ways to achieve this: by drilling a hole in the display, sprinkling a few small holes in the display, or making the display transparent in places where it is not. Required The camera is a hole for peeking.
No matter which method they use, they need to be able to pass light through the holes but it is not so big that they affect the feel or functionality of the touch screen.
Samsung OLED screens contain a yellow polyamide that is useful for ultra-thin or foldable displays, the cameras also need software color correction, so that a yellow filter is not applied to make all your photos look unpleasant.
