Galaxy without camera hole?
Full screen can be realized by hiding the front camera
The 'Under Display Camera (UDC)' smartphone competition, which is considered as the next generation form factor (specific device type), has been announced. UDC, which hides the front camera in the screen, is a true 'full screen' that removes notches and camera holes (holes) from the existing display, and is a technology that realizes even higher-definition cameras than before.
According to various foreign media such as Phone Arena on the 26th, Nokia's next-generation flagship (strategy) 'Nokia 9.3 PureView', which is expected to release in the second half of this year, is expected to be the first UDC smartphone. It is known that HMD Global, which produces Nokia brand smartphones, has raised the technology of UDC to commercialization level.
UDC features a display that covers the camera hole, so the camera is exposed only when you take a picture while sweeping the entire screen. When using a smartphone, it is possible to implement a full screen with an immersive feeling because there is no visual jam.
In the meantime, the notch, which allowed the display of the area to be displayed as much as possible while leaving the camera in place, and Samsung Electronics 'Infinity T Display', which drilled a small camera hole in the upper front, provided a wider display. However, no company has yet implemented 100% full screen. Last year, Xiaomi and Oppo in China released a prototype that applied UDC technology, but it was not released as a full product.
Samsung Electronics, the industry's No. 1, is also accelerating the implementation of the system LSI division. An official from Samsung Electronics explained the Galaxy S10 display technology at the beginning of last year and said, "Ultimately, bringing all sensors into the screen is the direction of future development." Samsung Display also introduced UDC-related manufacturing equipment.
Recently, Samsung Electronics Galaxy Store. Looking at the terminals appearing in the official advertisements of the airless air conditioner, unlike the previous year, when the actual products were mainly released, the application of the full-screen smartphone model with UDC continues to raise expectations.
As a result, foreign and other IT (Information and Communication) communities have decided whether to launch the UCC first in the 'Galaxy Note 20' or 'Galaxy Fold 2', which will be released in the second half of this year, or the flagship 'Galaxy S21' (tentative name) to be released next year.
However, Samsung Electronics was wary of expanding the interpretation that terminals appearing in Galaxy stores are simple models. The position that it is not decided when UDC loaded products will be released.
It is not known which manufacturer will launch the UDB-equipped smartphone for the first time. The industry believes that there are still many tasks to be solved to commercialize the UDC technology.
First of all, the UDC must hide the camera in the screen while allowing the light to enter through the lens. To do this, it is necessary to increase the transparency of the OLED (organic light emitting diode) display panel, but it is difficult to make it as transparent as glass until now. Xiaomi has introduced a UDC method that uses a process to drill a hole that is so small that it is invisible to the naked eye on the camera position through a prototype. However, it was criticized as an unnatural display even to the public.
The picture quality problem must also be solved. The question is whether the camera in the display can secure the amount of light as a normal camera in a low-light environment. This means that it is inevitable that the image quality deteriorates in a building or in a dark place. Another problem is that light leaking from inside the display enters the lens.
