Under-Display Camera
It is like hiding a lens behind a sheer lace curtainโdisplaying a seamless, full screen until it is time to let light through for a photo.
Definition A screen technology that hides the front camera completely beneath the smartphone display, eliminating distracting punch-holes and notches for a truly borderless view. The screen lights up normally when displaying content and allows light to pass through to the camera sensor when capturing a selfie.
Looking Out Through a Sheer Curtain
When you stand behind a sheer lace curtain, people outside cannot see in, but you can see outside clearly. An under-display camera works on this exact principle. Normally, the entire screen displays vivid graphics, but the moment you open the camera app, the area right above the lens acts like a transparent window.
The secret behind this magic lies in transparent display materials and spaced-out pixels. Right above the camera lens, the pixels (the tiny building blocks of the screen) are spaced slightly farther apart, and the electrical wiring is replaced with transparent, light-transmitting materials. This creates microscopic gaps that let incoming light slip through.
As a result, light reaches the camera lens without punching a physical hole through the glass. Users can enjoy fully immersive, edge-to-edge screens without annoying black dots interrupting their videos or games.
The Tightrope Between Screen Quality and Camera Clarity
Hiding a camera under a display panel is no simple feat. Because multiple screen layers physically block the lens, the amount of incoming light drops noticeably compared to a traditional front-facing camera.
When light is scarce, photos not only look dark, but the light squeezing through tiny pixel gaps scatters in all directions. This causes noticeable glare and haziness, making photos look like they were taken in a thick fog. In dim indoor lighting or at night, this drop in quality becomes even more pronounced.
Yet, simply reducing the number of pixels to let in more light creates a whole new problem. Lowering the resolution right over the camera leaves an obvious, mesh-like grid pattern on the display. Engineers face a delicate balancing act between keeping the screen seamless and gathering enough light for clear photos.
Under the Hood: How AI Fills in the Blanks
To be more precise, modern under-display cameras do not rely on optical hardware alone. Light that bends and distorts as it passes through display layers cannot easily be corrected by lens physics alone.
This is where AI-powered image restoration comes to the rescue. The instant you snap a photo, the phone's neural processing unit (NPU) springs into action, sharpening edges blurred by light diffraction and digitally scrubbing away artifacts and visual noise.
Trained on tens of millions of high-resolution images, machine learning models reconstruct lost colors and fine details in real time. While early versions suffered from noticeable quality compromises, newer transparent panels combined with advanced AI computational photography algorithms are rapidly closing the gap with conventional front cameras.
๐ค Common misconceptions
There are no display pixels directly above an under-display camera.
If there were no pixels, it would leave a black punch-hole just like older designs. Pixels are still present, but they are arranged with wider gaps and transparent wiring so light can pass through.
