MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641007411 A) filed by Bapatla Surendra Babu, Tenali, Andhra Pradesh, on Jan. 26, for 'bistable transflective display apparatus utilizing acoustically-triggered colloidal self-assembly for zero-power transparency.'
Inventor(s) include Bapatla Surendra Babu.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a bistable transflective display apparatus capable of video-rate switching and zero-power image retention. The apparatus comprises a micro-fluidic layer (102) containing a colloidal suspension of high-refractive-index nanoparticles (e.g., Titanium Dioxide in 8 mM SDS) and an acoustic field generator (104). By applying an acoustic standing wave (106), the system triggers Concentration-Driven Self-Assembly, causing particles to condense into a crystalline lattice at pressure nodes (108). This lattice is held by a Secondary DLVO Minimum (depth of 3-10 kB T), maintaining transparency ( 85%) without continuous power. For dynamic content, multi-frequency excitation achieves refresh rates exceeding 60 frames per second. A frequency-chirped "Chaos Pulse" overcomes the DLVO minimum and resets the layer to a light-scattering opaque state for outdoor reflective display operation."
