Recently, when the smartphones got punch hole display to fit the camera into the hole, then I thought for a moment that, How cool it would be if the camera placed under the display and showed only if we required it. Guess, what happened? It is going to be true soon. What is it and how it has become possible, you will get all the information in this article. So, without any further ado, let’s get started.
What is the under-display camera?
OPPO and Xiaomi are among those companies in the mobile technology markets so far, who experiments a lot and tries to bring the expensive technology within the range of common people. Recently they have achieved a breakthrough in mobile display technology.
OPPO becomes the first company to demonstrate an under-display camera (camera beneath the display) to the public at Mobile World Congress (MWC), held in Shanghai, China. OPPO published a teaser video on its official Twitter page on demonstration of how the camera will work actually.
Another Chinese tech giant Xiaomi also teases a video and revealed its under display camera too, just after the OPPO teaser. As usual, the camera is embedded in the top of the device but the cache is, it will be under the display, not in the notch or within a hole in the display.
It doesn’t appear to be a perfect system yet and you can clearly see that. In the teaser video, you see a faint outline of the camera lens underneath the active display. Compared to other notch-less solutions, like the pop-up cameras (One Plus smartphone) or flipping cameras (Asus 6Z), there are no mechanically moving parts to worry about here.
How does it work?
Instead of putting a border (notch) around it or cutting a hole in the screen (a punch-hole display), the camera is covered with a special-low-reflective glass with high transmittance that works with a redesigned pixel structure so that light can get through to the camera just like transparent glass.
The setup allows the area of the display to become transparent to take pictures, and after taking selfies the camera hides behind the display and that transparent area of display becomes a usable display.
The advantage of implementing transparent display over the existing camera module system is that it allows a larger sensor with a wider aperture lens and better image quality than its existing teardrop notches and punch-hole displays.
The area of the screen reserved for the camera still works with touch control, and OPPO and Xiaomi both claims that the display quality won’t be compromised.
The future of mobile technology seems very promising if you see the present scenario. However, OPPO and Xiaomi both do acknowledge that putting a screen in front of a camera will inherently reduce image quality. The common problems like haze, glare, and color cast need to be overcome.
Both of them say that they have developed algorithms that are tuned to the hardware in order to address these issues, and claim the quality of the images will never compromise and we will continuously evolve our technology to provide better images with it. OPPO also promises to launch a device with an under-display camera soon.
