MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049791 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 19, for 'amorphous memory nullification via entropic self-driven annealing apparatus exploiting deterministic thermal window coupling.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to flexible optoelectronics and display architectures. A technical problem is the permanent plastic and viscoelastic deformation (creasing) of polymeric substrates under persistent folding stress, degrading optical clarity. The solution is an amorphous memory nullification apparatus executing deterministic thermal window coupling. A foldable display device (110) features a polymeric substrate (140) with an operational fold zone (150) comprising a Tg-engineered polymer matrix (160). The glass transition temperature (Tg) is configured strictly between an ambient storage temperature and a steady-state operating temperature. In a device closed state (210), the polymer freezes in an oriented low-entropy state (220), yielding a permanent crease deformation (230). In a device open state (310), endogenous thermal dissipation (130) from an active OLED layer (120) elevates the local temperature across a Tg temperature threshold (320). This unlocks massive entropic restoring forces (410) that drive the chains to a random coil configuration (420), executing absolute macroscopic surface planarization (430) powered exclusively by harvested waste heat."
