AI Technical Summary

Technical Problem

Conventional optical systems in mobile devices are insufficient in reducing the impact of high-intensity stray light, which degrades image quality, and existing anti-reflective structures in non-mobile devices are prone to deformation due to environmental factors.

Method used

An imaging lens with a plastic lens element featuring a peripheral portion containing a two-dimensional array of columnar protrusions, optimized in density and arrangement to minimize stray light reflection, and optionally incorporating a light-absorbing coating to further reduce reflections.

Benefits of technology

The imaging lens effectively attenuates stray light, maintaining high image quality by reducing reflection intensity and preventing deformation of optical components, thus meeting high-end functionality requirements.
