Under Display Camera Another advancement by scientists in the world of smartphones. Full screen smartphones are a new glimpse of the future
Under Display Camera technology is constantly progressing in the world. One of the most important designs in the last few years is the bezell-less display. Consumers have mostly shown interest in the screen-to-body ratio. Which has inspired manufacturers to find new ways to hide or integrate the front part, especially one of them is the selfie camera. Mostly we have seen notch, punch hole, cut out and flip selfie cameras till now, which made the display look bad. That’s why manufacturers have tried to make the display full screen and enhance its beauty. However, the most advanced and integrated solution till date has been worked on “Under Display Camera” (UDC) to enhance the beauty of the display.
What is an Under Display Camera?
Under display camera is a front facing camera that is placed under the display of a smartphone and can be hidden when not in use. Unlike traditional selfie cameras it is invisible (UDC) technology enables manufacturers to offer truly seamless displays without any notches, punch holes, cut outs, flips etc. When activated a portion of the screen becomes transparent allowing light to reach the camera sensor
How does it work?
The core concept of UDC technology involves a combination of hardware and software innovation
1 Transparent display- A small portion of the OLED display is made with transparent material and pixel density that allows light to pass through when the camera is in use
2 Special camera sensor- The camera has to work under a layer of pixels and faces challenges like light modulation and low clarity. To compensate, manufacturers use specially tuned sensors capable of capturing more light and details
3 Advanced algorithm- The image generation algorithm is essential for improving image quality. This algorithm helps to correct the diffuse haze and color distortion caused by the screen layer on top of the camera
Development of Under Display Camera
The concept was first released in 2019 when companies like Oppo and Xiaomi showed prototypes. However it wasn’t until 2020 that ZTE released the AXON 20 5G. Which is the world’s first available smartphone with an under display camera. Though this innovation was unprecedented, the camera quality was quite different from traditional selfie cameras. There have been several computational processes to improve image processing and display transparency. Samsung Galaxy Z Fold 3 and Z Fold 4 incorporated UDC with better resolution and performance. But still not at par with traditional front cameras. Challenges faced by UDC technology
Despite its potential, under-display camera technology faces significant hurdles
Image quality The camera is hamper by pixels so capturing sharp images is very difficult especially in low light
Display artefacts The camera may have noticeable differences in brightness or color compared to the rest of the screen
Manufacturing complexity The UDC requires precise engineering to assemble which increases manufacturing cost and failure rate
Benefits and Applications
Despite its challenges, UDC technology offers several benefits
Aesthetics- Provides a simple display with no notch or punch hole which makes it great for gaming and media use
Ultra-modern appeal- UDCs offer a cutting-edge appeal that makes them appealing to early adopters and tech enthusiasts Makes it attractive for
Potential for other devices – Apart from smartphones, UDC can be use in tablets, laptops and AR/VR headsets where space optimization and aesthetics are important
Future of Under Display Camera
Current trends in UDC are still improving. Rapid advances in material science, AI-based image enhancement and display engineering are improving the technology. As these improvements continue, under display cameras can become a common feature in flagship mobiles and devices.
In addition, manufacturers are exploring multilayer displays, adaptive refresh rates and machine learning-based correction algorithms to make UDC more effective. It is believe that within a few years, under display cameras can perform as well as or even better than the old traditional selfie cameras.
Under display cameras are a reality. Full screen bezel-less display, which was earlier like a dream, is now coming true and it can be seen as a significant breakthrough while the road to completion is still being made. The progress so far is a new milestone in the industry. Represents a continual innovation that, as the technology fully evolves, promises to reshape not just smartphone design. But also influence the shape of a long and wide range of digital devices
