The smartphone will be "full screen display"!-Notch -free smartphones appear one after another
The iPhone series is equipped with a face authentication sensor, and there is a hidden area called a long "notch" on the top of the display.Therefore, iPhone 12 Pro Max is 6.Although it is equipped with a 7 -inch display, there are fewer areas that can be displayed.On the other hand, the number of Android smartphones that use the front camera for face authentication has increased, and it is common to have a "punch hole camera" that has no notch and a hole in the screen.However, there is still a hidden area on the screen, and when you watch a video on the full screen, you are worried.
However, recently, smartphones equipped with displays that have no punch hole as well as notches have come out in a row.Even if you display the full screen, there is nothing that blocks the screen, and you can get a high immersion even when watching a video.
"GALAXY Z FOLD3 5G", which was just announced as a Samsung flagship model, is a big topic as a smartphone equipped with a foldable display, but the display does not see the front camera.The front camera is built -in at the top right of the opened display, but the camera is hidden under the display.As a result, 7.You can fully use a 6 -inch tablet size screen.
The camera embedded under this display is sometimes called an "under display camera" (UDC) or an "under screen camera" (USC).If you look closely at the UDC structure, you can see that the display on the camera has a structure that allows you to pass the light required for photography by reducing the density.
The world's first Chinese smartphone maker OPPO was released in June 2019 a smartphone prototype model with UDC.However, ZTE was faster for commercialization, and in fact, Rakuten Big, which was released by Rakuten Mobile in Japan, was the world's first UDC -equipped smartphone.After that, ZTE also appeared as "AXON 20 5g", but in 2020, ZTE only commercialized two models.
However, in the summer of 2021, in the summer, the company will come out from each company one after another.First of all, on July 27, ZTE released "AXON 30 5G" as a successor model of AXON 20 5G.The display size is almost the same as AXON 20 5g, but the density of the display covering the front camera has doubled, and the part where the camera is embedded is not visible.Although UDC has a camera under the display, the display on the camera has a rough density.In AXON 20 5g, when the display was diagonally, the shadow of a small square was slightly visible in the upper center of the display, but in AXON 30 5G, it became difficult to see it.
On August 4, OPPO announced new generation UDC technology.As an OPPO, this is the third generation UDC, and it is said that UDC, which passes through the display, is improved so that a clear image can be taken by AI processing.In addition, it seems that the display side can be clearly displayed in the display part at the top of UDC, with improvements on the display side.Unfortunately, OPPO's announcement is only technology, and the release time of OPPO smartphones equipped with UDC has been undecided.
And on August 10, Xiaomi announced "MIX 4".In the MIX series, the first model appeared in 2016 as a big screen display model, and in March this year, the Mi Mix Fold, which is equipped with a foldable display, was released.In the past, the world's first smartphone "Mi Mix Alpha", where displays around from the front to the back side, were also announced, but this was a concept model.Nevertheless, Xiaomi has long been developing products that are particular about the "large screen".
Mix 4 is equipped with UDC and 6.We have realized that all 67 -inch displays are displayed areas.Xiaomi (June 2021, a counterpoint survey), which was the world's largest market share in the smartphone market.The fact that Xiaomi has launched a smartphone with UDC, and other manufacturers may be able to spread the adoption.
