Liquid crystal polarization gratings steer light to stabilize images, resolving the contradiction between device complexity and spatial resolution.
Oriented acicular microparticles in the functional layer boost contrast without adding thickness or complex manufacturing steps.
Continuous axis rotation eliminates visible interfaces between regions, enabling glare and heat control.
A printed layer between the touch sensor and flexible circuit board conceals bubbles caused by height differences, ensuring visual uniformity.
A dispersive prism folds light through multiple reflections within a compact volume to maintain optical path length.
Etching fused silica with nanoparticle masks forms voids that impart birefringence, overcoming low laser damage thresholds of specialized materials.
