The technology seeks to avoid the use of the perforated camera and removable mechanisms to gain more space on the screen.
The South Korean Samsung revealed that he is currently working on the next design of his folding screen phone Galaxy Z Fold. The ambitious bet is focused on the development of its own technology to place the selfie camera sensor below the screen.
According to the Korean media ETNews, which cites industry sources, the system that will allow the front camera to be placed under the screen, so that it is invisible, unlike current solutions such as the eyebrow-shaped section (nothc) and perforated camera, and also avoiding removable mechanisms, also called pop-up.
To use this system, the display unit of the South Korean company, Samsung Display, is developing a special version of screen for mobile phones, while Samsung Electronics System LSI will work on the camera sensor.
The screen will have a special design, with a greater separation between pixels to avoid light interference in the camera, while the camera sensor will be accompanied by algorithms to correct the image.
Samsung plans to incorporate under-screen camera technology into its new flexible-screen smartphone model, Samsung Galaxy Fold 3, which will succeed the current Galaxy Z Fold 2 and which is expected to hit the market in the third quarter of 2021.
Under-screen camera technology officially landed this year 2020 with systems like the one produced by Chinese manufacturer Visionox and ZTE Axon 20 5G, the first on the market that thus avoided the design with notch (eyebrow), perforated camera and removable or pop-up mechanisms.
This solution was based on five technologies– Use of special materials, dual control chips, circuits with a single controller, custom pixel matrix and additional algorithms for the selfie, as explained from ZTE.
In this way, the Chinese company used materials with high transparency in the design of the screen to increase the amount of light that the camera receives, and also developed an independent dual control controller and processor that help to synchronize the color between camera and screen.
The internal components and circuits were also designed with the aim of avoiding image interference. To improve consistency and screen transitions, a special pixel matrix.
Also, the 32 megapixel front camera makes use of an algorithm that optimizes its performance under different lighting conditions, with support for high dynamic range adjustments and with clarity and contrast enhancements.
