According to GizmoChina, details about the $4 that will be making use of the technology are scarce at the moment.
$4 had launched the Xiaomi MIX 4 as the very first commercially-selling smartphone from the company with an under-display. Its resolution was 20MP.
With the new tech, Xiaomi is planning to reduce the photo quality gap between under-screen cameras and regular selfie cameras.
Earlier, Xiaomi patented a smartphone design with an under-screen flip camera that can serve the dual purpose of the primary camera and a selfie camera.
The flip technology to be used in the phone's camera setup will enable the camera to rotate 180 degrees and serve as both a selfie cam and a rear-facing camera.
Xiaomi continues to pursue active research and development within the smartphone segment of the tech industry.
