How Under-Display Cameras Are Improving in 2026

Fact-checked by the VisualEnews editorial team

Under-display camera phones are finally delivering on a promise that felt premature just three years ago. Advances in transparent OLED subpixel routing and AI dehazing algorithms have pushed selfie image quality within measurable range of punch-hole rivals — according to GSMArena’s 2026 display technology overview, the gap in MTF (Modulation Transfer Function) scores between UDC and conventional front cameras has narrowed to under 12% on flagship devices.

This matters now because the entire premium smartphone market is converging on full-screen designs. Every percentage point of quality improvement removes a reason not to buy — and in 2026, the remaining objections are shrinking fast.

How Has the Display Technology Over the Camera Improved?

The core problem with early under-display cameras was simple: display pixels blocked light. Modern solutions reroute subpixels around the camera aperture, increasing light transmission from roughly 10% on first-gen panels to over 40% on 2026 flagships.

Samsung Display’s fourth-generation UDC panel, used in the Galaxy Z Fold 6 series, spaces OLED subpixels further apart above the lens area using a proprietary algorithm called “Pixel Sparse Array.” This increases per-pixel pitch without visibly reducing resolution to the naked eye at normal viewing distances.

Transparent Electrode Materials

Traditional indium tin oxide (ITO) electrodes absorb a measurable share of incoming light. Several 2026 panels now use silver nanowire composites, which are more transparent. According to Samsung Display’s UPC technology page, this material shift alone contributes a 15–18% increase in optical transmittance compared to ITO-based designs.

Xiaomi’s Mi Mix Fold 4 goes further, pairing the nanowire layer with localized refresh-rate suppression — the display above the camera drops to 1 Hz during photo capture, eliminating flicker interference entirely.

What Role Does AI Play in Under-Display Camera Image Quality?

AI image restoration is the single biggest quality equalizer for under-display camera phones in 2026. Because the display scatters and partially blocks incoming light, raw sensor data is inherently degraded — AI reconstructs detail that the optics alone cannot capture.

Qualcomm’s Snapdragon 8 Elite includes a dedicated “UDC Enhancement Engine” within its Hexagon NPU block. It applies multi-frame deconvolution at up to 30 frames per second, correcting haze, reducing halation around light sources, and recovering edge sharpness in real time. This is the chip inside the Samsung Galaxy S26 Ultra and the OnePlus 13T, both shipping with under-display front cameras in select markets.

Training Data and Scene Recognition

The AI models are trained on paired datasets — clean reference images alongside degraded UDC captures of the same scene. Google Research published work in late 2025 showing that transformer-based restoration networks outperform CNN-only models by 2.3 dB PSNR on UDC benchmarks, a finding quickly adopted by Android OEMs.

Scene-adaptive processing matters too. Night selfies previously showed the worst performance due to amplified scattering. In 2026, AI night mode for UDC cameras stacks between 8 and 12 frames, applying alignment and deconvolution before compositing — a process invisible to the user but responsible for the most dramatic quality jump in low light.

Which Under-Display Camera Phones Lead in 2026?

Three manufacturers account for nearly all commercial under-display camera phones available today: Samsung, Xiaomi, and ZTE. Their approaches differ in meaningful ways, and performance gaps remain despite shared underlying technology trends.

ZTE’s Axon 60 Ultra was the first 2026 device to use a dual-layer pixel arrangement above the camera, physically separating display and light-guide functions. Early reviewer testing on The Verge placed its front camera within 9% of a comparable punch-hole sensor — the closest any UDC device has measured.

It is also worth noting how these devices fit into the broader shift toward always-on display intelligence. Just as wearable technology now uses continuous sensor fusion to process biometric data in real time, flagship phones apply the same always-on NPU model to camera image restoration — turning a hardware limitation into a software-solved problem.

What Limitations Do Under-Display Camera Phones Still Have?

Despite major gains, under-display camera phones carry real trade-offs that buyers should understand before choosing one over a punch-hole alternative. Backlit scenes and direct light sources still produce visible halation artifacts that AI processing does not fully eliminate.

Display uniformity is a second concern. The pixel sparse area above the camera reflects ambient light differently from the rest of the panel, creating a faint visible ring under certain angles and bright lighting. Independent display analysis from DisplayMate Technologies found that 87% of tested 2026 UDC panels showed some perceptible non-uniformity under angular lighting — down from 100% in 2023, but not yet eliminated.

Video Quality Gap

Still photo quality has improved faster than video. Multi-frame stacking, the main AI tool for stills, cannot apply to real-time video without latency. Current UDC video at 4K/30fps shows measurably lower acuity than punch-hole rivals — a gap manufacturers have not yet bridged in 2026 shipping hardware.

For users who prioritize video calls or short-form content creation, this matters. The broader push toward richer mobile content formats — from social video to AI-powered visual search — means front camera video quality is increasingly a purchasing decision factor, not an afterthought.

Where Are Under-Display Camera Phones Headed After 2026?

The next phase of UDC development is already in prototype testing, and it points toward the remaining trade-offs closing within two product cycles. Micro-LED is the most important technology on the horizon for this application.

Micro-LED emitters are physically smaller than OLED pixels, allowing higher-density sparse arrays above the camera with less total light blockage. Early research shared at the SID Display Week 2025 conference demonstrated prototype Micro-LED panels achieving 52% optical transmittance — a figure that would essentially close the hardware light-gathering gap entirely.

On the software side, generative AI upscaling is entering the UDC pipeline. Rather than simply deconvolving captured data, models trained on 100 million+ face and scene samples can now hallucinate credible detail beyond what the sensor physically captured. This raises fidelity questions but dramatically increases perceived sharpness. The same edge-processing principles driving advances discussed in edge computing architectures are central to making this work without cloud latency.

Industry analysts at IDC project that under-display camera phones will represent 35% of all flagship smartphone shipments by 2028, up from approximately 12% in 2025. That trajectory assumes continued AI and display improvements — both of which are currently on track. For consumers keeping pace with the latest wireless standards alongside display upgrades, the comparison of 5G vs Wi-Fi 7 connectivity is equally relevant when choosing a 2026 flagship.

Frequently Asked Questions

Are under-display camera phones worth buying in 2026?

For most users who prioritize a clean full-screen design and primarily shoot stills, yes. The quality gap versus punch-hole cameras is now under 12% on flagship devices. Users who record frequent front-camera video should still consider a punch-hole alternative until the video quality gap closes.

What is the best under-display camera phone in 2026?

The ZTE Axon 60 Ultra currently leads on measured metrics with 420 ppi pixel density and 44% light transmission. The Samsung Galaxy Z Fold 6 offers broader software support and ecosystem integration. The right choice depends on whether you prioritize raw image quality or platform features.

Do under-display cameras affect display quality?

Yes, to a small but measurable degree. DisplayMate testing shows 87% of 2026 UDC panels have some visible non-uniformity in the camera zone under angular lighting. At normal viewing distances and in typical use, most users report not noticing it after a brief adjustment period.

Why do under-display cameras still look worse than punch-hole cameras?

The display physically blocks and scatters light before it reaches the sensor, reducing the effective aperture and introducing optical aberrations. AI correction recovers most of the lost detail in stills, but real-time video cannot use the same multi-frame stacking process, leaving a persistent gap in motion capture quality.

Which chip handles AI correction for under-display cameras in 2026?

The Qualcomm Snapdragon 8 Elite is the most widely used, powering the Samsung Galaxy Z Fold 6, Xiaomi Mi Mix Fold 4, and OnePlus 13T. Its Hexagon NPU runs Qualcomm’s dedicated UDC Enhancement Engine at up to 30 fps. MediaTek’s Dimensity 9400 APU performs a comparable role in the ZTE Axon 60 Ultra.

When will under-display cameras be as good as regular front cameras?

For still photography, parity is plausibly within one to two product cycles — approximately 2027 to 2028 — based on current Micro-LED prototype data and AI model improvement rates. Video parity is likely to lag by an additional cycle due to real-time processing constraints.
