Bottom-driven threaded shank rotates counter-clockwise to secure jewels in hinge holes without applying damaging torque to the ornament.
Segmented pin hole structures block stray light and focus display emissions, resolving image degradation while maintaining see-through visibility.
Separated front and rear sound cavities create an acoustic dipole effect that reduces far-field leakage while maintaining near-field loudness.
Position the waveguide on a pad before molding to establish a positional reference, eliminating complex mold tolerances and reducing production costs.
A single cavity electro-wetting lens eliminates fishnet patterns and black matrix reflections to enhance light transmittance.
