MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051643 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 23, for 'neutral-axis extended uniform segmentation for undistorted surfaces in foldable displays.'
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: "A micro-segmented vertebral fold-zone apparatus kinematically isolates flexible display components from bending strain while maintaining macroscopic optical continuity. The apparatus comprises a flexible substrate (110) patterned with an alternating structural array of rigid micro-segments (120) and highly compliant micro-joints (130). Active functional elements (140) are spatially registered to reside exclusively over the rigid micro-segments (120), with non-functional inter-element gaps (150) aligning directly over the compliant micro-joints (130). The width of the micro-joints (130) is strictly less than a sub-pixel pitch, rendering them optically imperceptible. Upon articulation, the compliant micro-joints (130) absorb substantially all angular deflection (210), spatially extending an extended neutral mechanical axis (230) via a stiffness gradient and forcing the rigid micro-segments (120) to undergo discrete rigid-body rotation (220). Consequently, the active elements (140) exist in a zero-strain region (310) with bending strain maintained below a predefined failure threshold, eliminating cyclic fatigue and optical distortion without requiring a macroscopic mechanical hinge."
