New Smartphone Sensors Merge Display and Camera Tech

ams OSRAM has introduced a unified sensing solution for smartphones that bridges the gap between what a screen displays and what its cameras capture. The technology was presented at the 2026 China International Optoelectronic Exposition, where the company highlighted a system designed to make mobile visual experiences more stable and accurate across varying lighting conditions.

Developed in partnership with vivo, this approach represents a shift from isolated sensors to an integrated chain. By combining front-facing under-display optical sensing with rear-facing spatial sensing, the system aims to help devices maintain true-to-life color and brightness, regardless of whether they are in bright sunlight or dim indoor settings.

Sensors Work Behind the Screen

A key component is a spectral color sensor positioned behind the OLED display. Unlike traditional sensors placed on the outside, this unit works through the screen itself to measure ambient light. It supports five-channel spectral sensing, allowing the phone to adjust brightness and color temperature with greater precision even when the display has very low light transmittance.

This setup helps eliminate the common issue of screen color shifting under different light sources. The sensor’s high sensitivity and signal-to-noise ratio enable fine-grained control, ensuring that the visual experience remains comfortable and natural. It also handles proximity detection and infrared suppression, which are critical for bezel-less designs where physical buttons are absent.

Rear Camera Gains Spectral Depth

On the back of the device, a multi-channel spectral sensor handles the heavy lifting for photography. This eight-channel component emulates human color perception to provide precise data for automatic white balancing and exposure. It is specifically designed to identify light sources and detect flicker, a common problem in photos taken under artificial lighting.

According to GN technics/mobile (en-US), this sensor improves color stability in complex lighting environments. By incorporating optical calibration data, it compensates for slight variations between individual devices, which simplifies the manufacturing process and ensures that every phone produces consistent photo quality.

Depth Sensing Expands Mobile Capabilities

The solution also integrates a direct time-of-flight depth sensor, marking the first time this specific technology is being used in a smartphone. This sensor provides real-time depth information across multiple zones, allowing the device to understand spatial relationships rather than just capturing flat images.

This capability supports applications like portrait depth-of-field effects and augmented reality ranging. However, the trade-off is increased complexity in the device’s optical stack. Manufacturers must balance the benefits of spatial awareness with the challenges of fitting these additional components into thin smartphone chassis while maintaining battery life and thermal performance.
