Under-display Camera: Issues With This Technology

The under-display camera is a technology available in very few current smartphones that allows front cameras to produce photos even while buried behind displays. In 2020, the ZTE Axon 20 5G was the first smartphone to feature an under-camera display.

To have a better grasp of how under-display cameras function on smartphones and other devices, we must first understand how camera sensors work and why putting them under a standard OLED panel makes image reproduction nearly impossible.

To capture photographs, our smartphone camera sensors require light. This implies that every camera sensor, including those buried beneath the display, requires light to process and produce high-quality selfies. However, our standard OLED panels are not transparent, which means that light cannot reach the camera sensor located beneath them.

For an under-display camera phone to function, the display or area above the camera sensor must be reasonably transparent. This means that the OLED panels used in under-screen camera phones must be modified to allow light and other signals to pass through. This is a difficult task, especially when it comes to coming up with scalable ways for millions of such panels.

Even though pop-up cameras were introduced to address the shortcomings of the notch display.

There will always be certain concerns in the back of consumers’ minds, no matter how strong firms make them. Will they crack if subjected to external force or pressure? As well as issues such as, is there a chance that the pop-up will stop working? And, to top it off, the pop-ups made the phones too heavy.

Despite its ability to provide users with the demanding full display they’ve wanted, the under-display camera had several flaws; we’ll be looking at those shortcomings in this post.

Cost.

Because it is a new implementation, the overall cost of the smartphone rises, and we must pay a premium to the producers.

Image Quality.

While under-display camera phones do a better job of concealing the under-screen camera sensor; The photographs they produce are marginally poorer than selfies taken by other, similarly priced phones.

Because a camera converts light into digital, the camera quality on these devices drops. The cameras here are located beneath the display; Making it difficult for the camera to pick up light, resulting in detail loss and poor picture quality. The quality of the cameras utilized here may improve over time.

Although manufacturers maintain that the camera portion is unnoticeable, this hasn’t always been the case. In the phones that have been released so far, there is a little pixelated part of the screen that may be seen from certain angles or if you look closely.

However, these concerns have been solved in current under-display camera phones, and we can see noticeable improvements, particularly on phones such as the Samsung Galaxy Fold.
