MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202511132528 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 27, 2025, for 'smartphone display screen system with smudge-resistant, antimicrobial, and anti-glare features.'
Inventor(s) include Aakriti Chambial; Poonam Saini; and Dr. Himanshu Sharma.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a smartphone display screen system with smudge-resistant, antimicrobial, and anti-glare features designed to introduce a tri-functional smartphone screen that integrates anti-smudge, antimicrobial, and anti-reflective properties into a single, durable coating designed to enhance hygiene, clarity, and sunlight readability. This multifunctional system combines three bio-inspired layers: a lotus leaf-inspired top layer that repels oils, fingerprints, and water to maintain a clean surface and smooth touch responsiveness; a middle antimicrobial film embedded with copper nanoparticles that delivers broad-spectrum, long-lasting microbial protection; and a bottom moth-eye nanostructured layer that reduces glare and enhances visibility under bright sunlight without additional power consumption. Although each of these technologies exists independently, their integration into one cohesive coating creates a self-cleaning, multifunctional screen that surpasses conventional solutions such as silver-ion coatings, matte films, and oleophobic layers."
