Do you consider built-in lighting features essential for your smartphone video calls?

Apple has introduced the iPhone Duo, which features a new Edge Light function on its inner display. This technology illuminates the screen borders to act as a virtual ring light for users in low-light environments.

Why it matters

The Edge Light provides a functional lighting solution directly from the device screen during video calls. It helps ensure the user's face is clearly visible even when ambient lighting is poor.

The Edge Light function uses the borders of the inner display to emit illumination. This technical implementation enables the screen to act as a virtual ring light during video communication sessions.

The players

Apple

Apple is a multinational technology company known for designing and manufacturing consumer electronics, including the iPhone and Mac hardware lines.

The details

The Edge Light feature works by illuminating the perimeter of the phone's inner screen to brighten a user's face. This built-in tool is specifically designed to assist with visibility during video calls conducted in low-light settings.

The Edge Light feature first debuted on Apple silicon Macs in 2025.

The Tech Race

The integration of display-based lighting follows the successful deployment of Apple's 2025 Mac silicon Edge Light feature. This expansion highlights a trend of migrating utility-focused interface features across the company's broader hardware ecosystem.

Users can expect improved video call clarity without the need for external lighting accessories. The screen-integrated light streamlines the mobile experience by providing necessary illumination directly from the device's own display borders.

The takeaway

This feature provides a practical alternative to portable ring lights for mobile video callers. Users should test the lighting in various dark settings to determine how the display brightness affects their specific video quality.
